Blender Compositing VFX Tutorial : Remove People/Objects from Videos [Node Editor]
Вставка
- Опубліковано 13 лип 2024
- In this Blender Compositing VFX Tutorial we will be removing people/objects from our footage. Be sure to check out our latest Add-on, The Darkfall VFX Add-on. It's a free add-on that contains 8 different effects and the Clone Node making this Tutorial outdated.. .. Check out the blog page here: bit.ly/2kB5XYt
When shooting in locations you can not control, there is always the risk of having unwanted people or objects in your shot.
For example, we want a nice shot of the lighthouse and the water behind but there is a man in the way.
With a few Masks and some Nodes we can easily remove the problem and get the shot we want.
I hope this Blender Compositing VFX Tutorial helps and as always Thanks for watching!.

simple, practical and short, just perfect!!! thanks for sharing
I'm glad you like it!.. Thanks for the comment!..
Omg this is so awesome! I never imagined that blender can be used for such things! Thank you very much
Hey Marvin thanks for the comment!.. Yeah I'm always surprised at what blender can do.. Anyway I'm glad you found this video helpful and thanks again for the comment..
No problem man! Im getting into Blender and your videos are really well done.
You got my subscription!
Thanks buddy! I appreciate the support.. Blender can be a little daunting at first but after a while it becomes much easier. Good luck with your project!..
This is a really great tip! Good work!
Hey, thanks for saying so Kenan!..
I think u are the very first youtube i've ever seen who answers every single comment. Great!
(The Vid too btw)
Hey Herbert, I'm glad you enjoyed the Video!.. I'm sure bigger youtubers have a harder time replying to every comment since they get many each day, but I try and answer everyone of them. If you take the time to leave a comment I think it's only fair that I take the time to reply..
Darkfall sure bigger youtubers who have like thousands of comments can't answer them all, but ive seem much smaller ytber than u are and they dont care about their comments :)
They will no doubt find it hard to grow if they don't care about the comments, and besides it takes less than a couple of mins to read and reply to a comment.
Darkfall exactly
Wow! This is kind of magic! You got yourself a new subscriber!
Hey thanks! :D
Another good useful tutorial.....great job!
Hey, thanks! Glad you liked it..
Great!!!
Thanks for taking the time to do the tutorial ;)
Thanks for taking the time to watch them :D
Prachtige tutorial!
Mogelijk is dit nu nog eenvoudiger te doen met Blender 2.90.
Ik had geen idee dat je Blender zo eenvoudig kon gebruiken om video te bewerken!
Hallo Mark, bedankt voor de reactie. Dit effect kan veel gemakkelijker worden bereikt met de gratis blender-add-on die ik heb ontwikkeld, het heet de VFX Nodes.
Check de link hier darkfallblender.blogspot.com/p/blog-page_8.html
Er zijn veel verschillende effecten, maar voor dit effect heb je de Clone-node nodig
Awesome tutorial, Great work!
Glad it was helpful! If you want to speed up your workflow you should check out the free blender add-on I have been developing, The VFX Nodes add-on : darkfallblender.blogspot.com/p/blog-page_8.html
It has the patch node, with the press of a single button the node will be added to your compositor and you can get the same effect but much quicker..
Great man! Thank you for sharing it!
My pleasure! Glad you like it.. I should also mention, I have been developing a free blender add-on called the VFX Nodes, it has a bunch of different effects for the Node Editor and one of them is the Clone Node. That and/or the Patch Node would give you the same results as in this video, it will build a single node to help speed up your workflow. If you want to check it out you can see the blog post here: darkfallblender.blogspot.com/p/blog-page_8.html
I was reading about Adobe doing this with Affects and wanted to do it in linux . Great video. Thanks
Hey no problem thanks for watching!
Very, very useful. Thanks for sharing.
I'm glad it helped! Thanks for the comment!..
Great tutorial! Thanks!!
Hey man thanks for saying so!..
really helped me, thank you
Im' glad it helped! thanks for the comment!
thank you very much my friend plz keep going uplaoding videos
:D thanks for the comment. I appreciate your support!..
Nice channel 👍 new features in Blender I`ve never known about. Thank you, man
Hey thanks for saying so.. I am glad you found it helpful!
@@DarkfallBlender all of your videos are helpful, prewatching all of them and want to learn)) and waiting for new ones in Blender 2.8 😉
Glad to hear it :D im not sure when I will get around to 2.8. The bigger uploaders will cover everything anyway ;)
@@DarkfallBlender not sure. Special feature of your channel - video anf vfx and composting. And there is not enough info about this on all of the blender-resources. But it is very interesting and amazing and I'm very glad to find your channel 😉
wow, nice!
Thanks for the comment!..
BADLY MISSING SUCH TUTORIALS!
😥😥😥
Leuk !Bedankt..
Huh I just searched up masking in blender to see if/how it could be done because I'm curious and this video came up. Definitely will be using this in the future. Thanks for the tutorial!
The Masks in blender are pretty good.. at first they may be a bit of a pain to get used to, but after a while they become really easy to use.. Not to mention useful also..
I have used the masking tool so many times in various projects, but this example I think shows how useful it can be. Not only removing a person from a video but the background is also moving.. Of course this wont work for every video but I think you get the Idea..
I'm glad you will find a use for this and thanks for the comment!..
No problem. I'm planning on attempting some motion tracking projects and wanted to be able to remove printed trackers in blender after I've taken the video. But seeing I can also use it for much larger things is awesome.
I did a video on how to remove Tracking markers on a Face, I think its the same steps pretty much, just like you said its on a different scale.. You would track the markers, then create the small masks and then parent them to the trackers (since its moving) and composite the same way in this video..
Anyway good luck with your project!..
Oh cool! I'll check it out!
Un genio! Gracias!
¡Gracias por el comentario!
"out praying to the ocean god" 😂
Lol.. It's hard to remember a mythical deity's name and record a tutorial at the same time.. So I went with "Ocean God" and I'm sticking with it..
Hi,
Not sure if this is the right video to ask this question. I watched some of yours, blender frenzy and Ryan King and they make sense.
My skill level is I guess about middle beginner.
My wife is making some tutorial videos ( Writing Chinese ) , she has some marks on her face she is sensitive about. To reduce them the best I have come up with is a mask on each cheek with points on either side of the eye, below center eye and jaw /ear. I can get tracks on the jaw / ear and eye brow.
Making the mask follow the tracks is fine, using parent.
But I then have to go through frame by frame as moves her head and move the nodes of the mask to keep the shape and exact position.
Is there a way to automate the mask reshaping as she moves?
I can't get any more tracks?
The best I thought of was a makeup pencil to make black dots when each point of the mask should be and parent each mask point to its own track.
Is that a sensible way of doing this?
Sorry for asking a dumb question, Im a southerner and blonde.... remembering to breathe in and out again is taxing.
Thank You
Jessica
Hello! Could you please share a link of the video footage? That would be wonderful!
Really good tutorial, I never thought something like this is possible in blender. Aaaand is this by any chance recorded in Croatia ?
hey Pavol, glad you like it. As for t footage, it was downloaded from the internet so I am not sure where it was recorded.. I guess it looks familiar to you?.. Also I should mention, This effect can be done with one single node, The Patch Node. It can be found in a free blender add-on I have been developing. You can check it out here: darkfallblender.blogspot.com/p/blog-page_8.html
@@DarkfallBlender Thanks for the response :D yeah it looks familiar to me
Is the process the same for when the camera is moving? I'm assuming you just animate your masks?
Yeah if the camera is moving you can just animate the mask. If your object or person (or what ever you are trying to remove) is still, you could just track the object then parent the mask to the track. That way the mask will move along with the object saving you some time..
Thank you!
Great tutorial! There is one thing you might better change with your mic: let it record all the time, not only when you're speaking. Because there is always a little bit if noise (which is okay) but it keeps cutting of and that's a little bit annoying.
Anyway, keep up the good work :)
Hey thanks for the comment!.. Yeah the mic I use has a noise filter and I always have it on.. I could turn it off and see how it goes.. thanks again for the comment!..
great video. how can we use the same technique to remove static text from video?
Thanks for the comment, It would be the same way but without animating the mask..
When i want to remove a object on the street or other objects and the camera is moving backward or other camera movements, then the place where i masked the object out with the translate Node then i get a street ground in the mask place with out the object but when the camera is moving this street ground will look different because this same street ground with out the object is not any more at the same position do you have any idea who i can still have the same street ground from the beginning that i make with the translate Node also when the camera is moving that i also have the same streeet ground?
Hey ZGames.. It all depends on how the camera is moving would make me approach it differently but say for example your camera is moving backwards as you mentioned. You could add a couple of tracking markers and use the data to move your Translate nodes so your corrected image (in the mask place) should be the one you need.
I did something similar with the offset x and offset y Tutorial you can see here: ua-cam.com/video/_fpiTDX9Ccs/v-deo.html
SO you can use the Offset x and offset y technique and use it to move your translate nodes for your "Clean image" or the new image that has no people/objects.. But again this may not work depending on your movie clip/camera movements..
I hope this helps!..
how do you do this on 2021 blender? the node editor has been split into texture and geometry editor and i cant switch it to scene view anywhere.
Lol 2021 blender? a version number would be better but I know what you mean.. I am not sure when it changed but the Node Editor is just called the Compositor. Also just to let you know, this process can be made even easier by using the VFX nodes (a free blender add-on.) It will add the nodes for you and package it into a single node. If you want to check it out you can follow the link here: darkfallblender.blogspot.com/p/blog-page_8.html
Is this the same process if you want to remove the video background, and if not, then how do you remove video backgrounds (without green screen) if you just want to keep the person in the video minus the background (or with a transparent background) and export it that way?
Yeah this would be pretty much the same process all you would need to do is invert the mask.. You would have to take more time and detail to rotoscope around the person...
@@DarkfallBlender Ok, thanks
No problem and good luck with your project 👍
And how you would do the opposite? I mean keep the image of the guy dancing and deleting the backgrond?
seen the comment below, thanks
Good tutorial however i did everything exact to the point of adding translate node. When i use the X slider it does not move the mask. Maybe i have done right but it might be to do with the mask, for example i use Alt C to close the points and go from there. What if it is because all the points are still selected as in the a key ? Hope you figure my problem there.
Hey RWF, You mean if all the points in the mask are selected?.. As long as the mask is closed (like you did with Alt C) it should not be a problem. I would think it would be a problem with the Nodes.. I should also mention that I have been developing a free blender add-on called VFX Nodes. It has a bunch of pre made nodes with different effects, the Patch Node is essentially this same effect but in one single node group. You can check out the video on my channel or check out the blog post here: darkfallblender.blogspot.com/p/blog-page_8.html
@@DarkfallBlender Thanks for the rapid response. I will get that add on but first let me explain what i figured out. I loaded a still image into movie clip editor and followed your instructions from there . It did not work, however on an actual movie clip it did work but still a problem there. The problem was the area i masked when using the translate node X axis it was moving stuff from the right of what i masked. Other than that amazing tutorial that has made me have a go at other tutorials you have made. Definitely. subscribing to your channel.
So when you load in a single image into the movie clip editor and then say move to a different frame it will cause issues (I think that was one of your problems) Another thing, in your render settings make sure the resolution Percentage slider is at 100% (this is a common problem and will effect your output in the compositor) The vfx nodes will auto set the % slider when you add a node. I think the % slider will effect your Translate for the X..
If this is still not working you can try starting a new project, use the VFX addon and see if you get the same result?.. Also thanks for the support 👍!
@@DarkfallBlender GOSH At last it worked a real treat. Others with the same problem as mine will benefit from this topic. Now i want to have a go at the one you did with removing cars on that video so that only one car is seen driving on the road. Anyway i downloaded that vfx add on of yours and although a bit complicated for me at the moment will help me to do good stuff once i learn them.
Glad you got it working. Yaeh the car one is very much the dame process and again can be simplified with the use of the Patch Node.
There are some videos on my channel on how to use the nodes and dome info in the blog but if you are still having trouble just let me know..
Im still beginning to learn blender, a convert from davinchi.
I work mostly on videos around 30min. Is this method scalable ?
Also, my wife needs to some skin blemishes such as freckles , scar etc davinchi has some filters which help.
Please would someone give me some pointers on where to look to learn how to do such skin touch up in Blender.
I'm really tired of davinchi and really want to change , Blender looks great.
Also I'm a linux user, sometimes Mac. MS does not like any of my pcs, which is fine, I dont like ms so its mutual.
3 min or 30 min the procedure and result should be the same the only different is the time masking (if animated mask is needed).. As for your second question, it;s certainly possible. I did a video on a "hollywood airbrush effect" you can check it out here: ua-cam.com/video/RNIeLEOPKFU/v-deo.html
@@DarkfallBlender Thank you very much for replying. I will take a look. Sorry for asking dumb questions I am still very new to Blender.
The only dumb questions are the ones we don't ask.. We all gotta start somewhere so don't worry..
Which software is it please
Blender : www.blender.org/
At 4:42 came across an issue. My mask is the incorrect size and in the wrong position relative to the movie clip showing in my backdrop. It is smaller and located more towards the middle of the screen. I have double checked that my nodes are the same and started from the beginning again to make sure I didn't make any mistakes. Any idea why this is happening? Here is a picture of what I have imgur.com/a/CQAmKZq
Hey Ryan, Make sure your resolution is the same as the movie clip you are using Then under that make sure the slider is at 100%
That was it! My slider was at 50%. Thanks for the quick response.
Hey no problem buddy.. good luck with the project..
I followed these instructions... but when I preview the clip on the compositing tab, the mask looks exactly as it should (which is good). When I render it out though, There is no mask whatsoever. Am I missing a step or something? Please help!
Could it be your render settings? is the Video resolution the same as your movie clip? also is the percentage slider at 100%?
@@DarkfallBlender none of those settings are any different from the original video, no. The percentage slider is at 100%.
On the video editing tab it is the original video. How to I get what I have in the compositing tab to be there? I feel like that's the issue maybe? It's only rendering the original video, not what I've created in the compositing tab.
You mean the other workspace? that shouldn't make a difference..
If you check the compositor and it is plugged into the composite node?
Also, I have been developing a free blender addon called the VFX Nodes, it will add the nodes into one single group called the Clone Node with the click of a single button.. You just need to add your masks as normal.. You can check it out here: darkfallblender.blogspot.com/p/blog-page_8.html
or check out the videos on the channel..
Is there a way to invert the selection so that you could remove the background and keep the subject?
Yeah you can just add an invert node after your mask (in the compositor) but you will have to refine your mask and make it fit your person perfectly (also known as roto scoping).. It's not as easy since it takes more time but yeah totally possible..
Also, just to let you know: I have been developing a free Blender Add-on called the Darkfall VFX Nodes.. It has a whole bunch of custom nodes including the Patch Node and the Clone Node.. It will save you arranging the nodes yourself.. you can check out the Blog post here: darkfallblender.blogspot.com/p/blog-page_8.html
Darkfall: That’s very intuitive. The pickle I’m in is I was using Adobe after effects and the roto-brush does that exact thing frame by frame automatically. Unfortunately, I’m using the trial version of After Effects and there is no way (that I have found) to export my footage in a way that can be played. So, I’m looking for free solutions that don’t require me to outline my subject frame by frame every time. Do you have and tips or solutions to offer? Any help means a lot
I see.. roto scoping can be done 5 frames at a time (in some cases) which will make it slightly easier but most times it will need frame by frame.. It can be time consuming but it's worth the effort..
That being said, for some videos we can use the difference node.. This would require you to first have a clean plate image of your back ground(so just the bg and no actor in the shot) and secondly your background needs to be stationary (not just camera motion but no motion at all).. Again this is very specific and probably won't help in this scenario..
Darkfall No no, actually. That helps a lot. My footage all takes place in a single room with the camera facing a wall
What software is this?
Blender - www.blender.org/
Can you do the same but for the background? Leaving only the person there?
You can remove the person but it would be more work. You would have to animate the mask and do whats called Roto scoping (fancy name for going frame by frame and moving your mask to match the outline of the man). Then once you have animated your mask you can jump to the compositor and just add a mix node, plug in your movie clip and plug in your new movie clip (the one you want to replace the old background with) then add a mask and plug into the factor of the mix node.. I also created an Addon called the VFX Nodes with you could use to create the nodes for the Patch node and the Clone Node
Check out the Blog Post here: darkfallblender.blogspot.com/p/blog-page_8.html
@@DarkfallBlender yes, I know that. Iam doing this technique with resolve and I hate it because it takes ages and makes my hand hurt. I asked because I thought there would be an easier way in blender, because I saw a guy who showed how to track faces and remove things like pimples or stuff in the background, all with a plugin that gives you a 3d model of a human head.
It depends on the scenario I guess. For example, if th footage was on a tripod and the background did not move but the actor does, you could create a quick clean plate (a still shot from before the actor enters the shot) then use a difference node it would remove the background since the node will only show the difference (that being the actor).. Though I guess that's not going to be helpful for other cases.
You said about how you saw someone remove pimples, that would be easy and we have done things like that before. I also have a "Marker Removal" node that you can use to remove things from actors faces (no models needed)..
Again it's always "scene dependent"
@@DarkfallBlender thanks
No problem! and good luck with your project!
Help! When I slide X axis in 'Translate' node my original man stays put and another one appears to his left! Followed this early stage of your tutorial five times to make sure I was doing it all correctly. Any suggestions?
Is the translate node on the correct string?.. You could try and swap the inputs round on the mix node.
Thanks for getting back so quickly. All nodes connected as per your tutorial. I changed the inputs round on the mix node and although the man didn't duplicate, only some of him disappeared then returned erratically. I'll keep working away and see how I get on. Once again thanks for responding and producing an exciting tutorial.
Hmm, it's strange. When you connect the nodes it sometimes doesn't update. Once you connect everything just reconnect the string into the viewer node or (if you have the node wrangler add on enabled) hold ctrl+shift then left click the mix node.. This should refresh the backdrop.. (you could also check "Auto Render" at the bottom - this may help) Anyway I'm sorry I couldn't help you any more then this without seeing the problem It's hard to guess what it could be.
Think I may have a problem with Blender - I followed one of your other videos using tracking markers and masks to remove specific areas. Although while scrubbing through the markers and masks tracked the areas they did not remove/mask those specific areas. Think I'll re install Blender. Thanks for your help and advice.
Im not sure if that will fix the issue.. It would help if I could see your process.. So when you add the mix node and then the mask and connect them up, at first nothing changes but when you add the translate node (to the bottom string) and then change the value of the translate now the man should move.. in your case what happens? I think it may be something simple and can be fixed but without seeing the problem it's hard to guess what it may be.. If you can record a video of you trying this tutorial and then posting it on my facebook page, I might be able to help..
Software name used in it?
Blender.. www.blender.org/
Removing all the actors from a movie
Only if they are annoying 😉
You only needed two masks for that. Even one would have been enough if you had used Gimp or Photoshop to create the missing rock part (using a still frame from the footage) and add it back on top of the scene. Look here for the node three and exemple of the rock image on transparent background -> i.imgur.com/Q60iq3Q.jpg
What about lighting changes? When you use a still frame it wont change when the lighting does.. In this example the lighting does not change and yes you can get away with going into another program and creating your image but in my opinion its a waste of time. In most other cases the lighting may change slightly especially outdoors and a still frame will stand out..
It clearly is faster, if you're used to photo editing. You're right about the lighting, I didn't think of that because it's not an issue on this footage. Though, you can animate the value of a color correction node, or a simple "hue/ saturation/ value" node. I've used this technique once.
Your second mask can be avoided, in the "motion tracking" window you can add located feathering on your mask, this way your mask is only blurry in the sea area, not the rock/feet, you don't need the blur node.
I don't see how its faster to stop and open up a program just to create an image when I can create a mask in the same program I am already using. The workflow is much better IMO but we all have our preferences I guess. As for the feathering you are correct but I prefer to use a blur node. again its all down to your preference. Creating an extra mask takes only a few seconds... anyway, I appreciate the comment!..
You're welcome, I admit that I'm so used to photoshop that it's the first idea that poped when I saw your video. Keep up the good work, I really enjoy watching your channel!
ohhh yeesss docs.blender.org/api/2.79/bpy.app.translations.html looking forward thx
After removing someone can you add some one
Hey, yeah once you have removed that person or object, you can then add another person or object on top of that movie clip as you normally would. I should also mention, I have created an add-on that helps with tasks like this. You can use the Clone node or the Patch Node to remove someone from your shot. It will save you time by adding the nodes you need with a single button : ua-cam.com/video/HyPSR1v6sps/v-deo.html
That is a video of the Darkfall VFX Nodes addon. You should note that this was version 1.0 and we are now on version 1.5.. So you my want to watch the other videos in that series to see what has changed. Of you can download the Addon from our blog (link in description)..
@@DarkfallBlender Maaaan I appreciate your response how much does this cost to download & what's the link
It's no trouble, as for price it's free and you can download it from our blog: darkfallblender.blogspot.com/p/blog-page_8.html you can find the link to the download there.. If you need help installing the add-on you can watch one of the videos, I think version 1.4 shows me installing the add -on there..
@@DarkfallBlender Okay cool I appreciate it I wanna use a old wwf entrance but remove the wrestler & insert myself lol
Lol fair enough.. You could use the Patch node and remove the wrestler, then film yourself in front of a greenscreen then add yourself on top.. I did a couple of videos about adding green screen footage to another movie clip.. One of them the camera is moving so you have to track that shot as well, if you want just search for green screen in my videos and you will find it.. Good luck with your project,..
The disabling and enabling of the microphone is more than just annoying. If it's a noise filter, please reconfigure it, or add some white noise to disable its effects.
This video was from a while ago, I'm sure the audio in the newer videos is better..
Joseph Stalin would've loved this!
Ooooo kaaaay...
after effects but free
😄👍
there is no stamp tool? lol
There is a Clone Node.. Check out the Darkfall VFX Nodes Add-on >> ua-cam.com/video/HyPSR1v6sps/v-deo.html Just to note, I have released version 1.0 1.1 1.2 1.3 and now 1.4.. You can watch the videos to see whats changed or just download the add-on and start using it..
What apk link plzzz
Apk link?
It's not android
but it cant work in a more details video
Cant?.. I've not had a problem with this technique. Also the water is quite detailed..
Info, you are wrong! This works many situation.
Okay.
Remove one person from 10 persons who is in series
It's not impossible... Just a lot more work.. You can roto scope around your object then clone from a clean area, Or create a new clean plate for it and use that. It's more work but it's certainly possible.
Nice tutorial but the technique is to specific for this scene.
I'm not sure I follow.. using this technique you can remove Objects or people.. We have done this a few times in a few different shots..
@@DarkfallBlender Well, you need to have a shot that contain background that can be moved into the place of the object/person to be removed, like the ocean.
Uhm, No.. No you don't.. If you wanted to use a Clean plate, you could use that instead of the original video. Using Clean plates are ok but they are limited when it comes to any lighting changes.
All this complicate shit when you are just moving a video layer to the right. You can do the same thing in AE or Premiere.
Then do it in AE or Premier.. This tutorial is to show how its possible using blender..
For people who already use blender, this is much easier than installing an entire editing suite for one feature...
