Blender Compositing Tutorial : Remove people from video [VFX]
Вставка
- Опубліковано 31 бер 2019
- In this Blender Compositing VFX Tutorial, we will be revisiting a former tutorial, How to remove people / objects from video.
Be sure to check out our latest Add-on, The Darkfall VFX Addon.. It's a free add=-n that contains 8 different effects and the Clone.. Check out the blog page here: bit.ly/2kB5XYt
In this example video we have a few more things we need to remove and I think we did a pretty good job. Of course if you spend more time on your project you can make it look even better. The video quality was not the best and then with Compression it looks even worse, so be sure to use high quality Background Videos when you are working on your own projects.
Since we have a few people we want to remove from our video, we will be creating "Super Nodes" or Mega/Uber Nodes to help speed up our workflow. Once we have created a new Node Group (Which I decided to call it the Patch Node..) we can bring that node into future projects and save even more time.
I hope this technique helps you in your future projects! if you found this Blender compositing Tutorial helpful be sure to hit that subscribe button for more..
As always, thanks for watching!.

Nice tutor, I didn't cope with my video, but I learn a lot from this 25 minutes. Tnx.
What problem are you having?
Truly great! The best thing about your video is that you have subtitles in hindi. Love from india
Hey no problem!.. I am glad you like it 😄👍
amazing tutorial
Glad you think so! 👍
Haha I always wanted this. I mastered in photos but thank you for this.
I'm glad this helped! 😀 thanks for the comment!.
I have to try this ..Awesome ..Thanks
Thanks for the comment Johan!..
NICE!
Thanks!
This is just insane, I think its maybe way easier to ask the people to travel to that location again and shoot the video again
😅 Anyone working on a zero budget or even minimal budget would disagree.. To be fair It is quite a lot of steps so I have been developing a free blender Addon Called the VFX nodes.. With the click of a button the Addon will do most of the work for you. The Nodes will be added as a single Node in your compositor.. For this Effect you can use the Patch Node. You can check out the Addon here: darkfallblender.blogspot.com/p/blog-page_8.html or check out some of the video on my channel..
@@DarkfallBlender Video editing surely is a complicated process. I guess it must be complicated, if one wants to achieve such magical results :). Thanks to lads like you and these awesome tutorials, even these complex processes seem feasible. Big thanks for what you are doing!
😄👍
Now I prefer use IA
Again a pretty good job :) I just wondered about why you are using "mixnodes" for composing your layers together. It's allright to do so and it works just fine, but maybe you have there a special reason why using mixnodes instead of alphaovers? I tried this "grouping" of node-setups too, but for me it was always to tedious to control this setup, with renaming and stuff (ofcourse it would safe time later in next projects).. i like to group this kind of node-setups with "ctrl+j" .. so i got it visuel seperated from my full-nodetree too, but i can hold it inside the overview for everything.
Nice Video, i like it, there is so much wich could be added for this shot.. i am thinking about of doing it with your permission.. maybe some rebuilding of this rocks to achive more "depth" for the finalrender.. adding some animated cloudtextures imitating that sparkling foam above the waterlevel to clean this rebuild up .. i know it just was a tutorial for this removing effect .. but iam always full of ideas if i see projects like this :)
thanks for sharing and blend on :)
Hey Stoerfish, thanks for the comment buddy!. Yeah I have no preference when it comes to simple mixing like this. I generally use Mix nodes unless I NEED an alpha over. Since the effect works either way I encourage you to use what ever you feel comfortable with.. Ctrl + J , i believe is creating a frame, and pretty useful for tiding messy nodes up but I think the Node Group or Super Node is much cleaner and easily appended into new files. I like hoe we can do the job once then bring in the nodes we need in the future..
As for the Background Video, I don't own it and the link is in the description sooo go for it.. I always get Ideas when looking at videos like this and yeah this tutorial was about how you can clean up videos that would have been unusable otherwise.. I think I will use this video sometime in the future and now it's "clean" I will have less work to do ;)
Anyway good luck with your project and again, cheers for the comment!
As far as I know, hitting Ctrl-G creates a Node Group so I think that is what they should be referred to as. Also, you could save yourself some time by putting the Blur node into the group as well and give inputs called Mask Blur X and Mask Blur Y (or just a single Mask Blur going to a Value node to feed into both the X and Y values of the blur node). With this particular video, you could have saved yourself even more time by simply zooming into the upper left part of the video which would have cropped out the people at the right and bottom.
Hey Jeffrey, Yeah it makes a node group, though if you have multiple node groups (that do different things) it would be best to call it something you can easily identify.. As for the nicknames, (Super nodes, uber nodes ect). I don't really mind what people call it.. As for the Blur node, I was going to add them to the group but I wasn't sure how to be able to control the Blur amount since there is no socket. Nor can I find a way to add a socket to the Values so if you know how, I would appreciate the knowledge..
Now for the "Cropping", Yes it would have saved time but that would have defeated the purpose, not to mention the loss of video quality. The fact is, even if the person is in the middle of the screen, this can sometimes be an effective way to salvage footage that would have been scrapped otherwise..
anway, thanks for your comment
@@DarkfallBlender I didn't notice that there were no input connections for the X and Y values on the blur node. It seems there are a lot of nodes like that and what with drivers not working well with nodes, that seems kind of problematic. Haven't been playing with 2.8 yet, though, so don't know if it has improved there.
However, after a bit of head scratching and reading, it seems that if you give the size input a number the X and Y values in the blur node become multipliers. Set them both to 1 and make the size 30 and you get an X and Y blur size of 30. Because size is an input, it can be put on your node group's inputs as well.
It would have been nice to be able to simply add a Socket to the Node but your work around is pretty good! . I will certainly incorporate it into this "Patch node" and any others that need it..
Thanks for sharing!..
Excellent video from which I learned much, many thanks. I like the Node Group, so much easier with multiple patches. I tried to append the saved node to another Compositor set up but it just doesn’t appear. Using Blender 2.82. Any idea why I can’t append the Node Group
Hey Paul, glad you liked it.. I have a better option for you!. I have been developing a free blender addon called VFX Nodes. It has a whole bunch of effects and tools, one of them being a Patch Node. This will add a single node which will give you the same effect as in this video. If you want you can check out the Addon here: darkfallblender.blogspot.com/p/blog-page_8.html
Ahhh! Cool, sub
Hey Rain, thanks for the comment! I am glad you like it. Just to let you know, I have made an addon called the Darkfall VFX Nodes, and within it, there are tools like the Clone node, Patch Node and more.. The addon will add the nodes you need so it will save you time for this kind of effect.. If you want to check it out, you can see the Post here: darkfallblender.blogspot.com/p/blog-page_8.html
@@DarkfallBlender much appreciated, I wish I will become like you in blender vfx some day.
If you stick with it, I am sure you can!. When I first started I was totally lost!. Blender has a bit of a hard learning curve at first but after a while you will get the hang of it!..
Great tutorial, very good indeed. Just one thing, at 9:05 you refer to an add-on but I can't make out exactly what you call it, and I wouldn't know where to get it. I think you said Node Render add-on?
Hey Stuart. glad you like it.. The Add-on I mention is the Node Wrangler add-on which is built in to blender.. Just go to Edit > preferences > add on section and search for node wrangler. You can then click the check box to activate it.. I would also note that this removal effect has been simplified even more by using the Darkfall VFX nodes addon. It has a bunch of pre built nodes like this removal effect saving a whole bunch of time.. If you want you can check it out here: darkfallblender.blogspot.com/p/blog-page_8.html
You just need to download the script and then again in the addon section (in the user preferences) you can click install from file and select the VFX node addon.. up to you 👍
My movie clip I got from the link is different. It's much longer so I can't follow along, and it's 1080p. What frame should I crop it on to get your identical video?
Yeah, I think I mentioned it in the video but I Edited the clip to stat a little sooner also I just reduced it to 72o
Great tutorial! By the way if I wanted to not remove a person, but to place a object behind him so the object will be partially covered by the person how can I do it?
Hey Dark GT, thanks I am glad you enjoyed it! So yeah you could easily achieve the desired effect using masks. The technical term would be rotoscoping and though I do not specifically have a video on rotoscoping we actually have done it many times in many videos (so if you followed some of my other videos you may already have done it!).
For example in the Hoverbike VFX shot : ua-cam.com/video/92MPQwiEjjI/v-deo.html
we are using masks to take a section of the road and move it over to where the wheel should be.. Making it look like its flying.. you could use the same process to take an object in the shot (or you can use a different video/ image) and position it behind your actor.. then you can create a mask around your actor and composite them over the top of your image
Is it necessary to increase the samples from the default. And if we use the EEVEE render engine do we lose quality on our movie clip?
Like in 2.79, when we render from the compositor, using movie clips (not using a render layer) we don't need to worry about the samples. Samples would only be a problem if you are using a Render layer node or Rendering from viewport... As for Eevee vs Cycles, again we are not using the Render Layer so there is no difference in speed or quality when it comes to this technique..
@@DarkfallBlender Thanks...
No problem Buddy!
Hey would this work for removing some background in a video? Me and my team are trying to remove foliage as well as buildings that are in the background of our footage
As you can see in the video we replace a section of the background with a clean section.. So, yeah depending on the situation, it should be fine.. Also just to let you know, I have been developing a Free Blender Add-on called the VFX Nodes. It has a whole bunch of effects and tools and we have the Clone Node and the Patch Node.. You can use one or both to achieve this effect. If you want you can check it out here: darkfallblender.blogspot.com/p/blog-page_8.html
How many RAM you have in your system at the time of making this video?
I am not sure, it was a different computer.. but It should not be a problem for low spec computers.
How would you go about Hiding a Mouse pointer that inadvertently landed up in the middle of your screen recording and everything in the video moves all the time?
Same way, no? I guess you would just need to animate the Mask and maybe keyframe the BG image position..
Hi, I have finished all the proces but it only renders the original video instead of the modified one. What should I do to fix this
Without seeing your Compositor Set up, I would only be guessing.. Take a screen shot and I will take a look.
I’m making by a Mother’s Day video of my youth group and one of them asked me to crop out their necklace. Am I able to do that on blender 2.8?
It's nothing to do with the version of blender, it has more to do with the footage?... Is the camera moving? is it on a tripod? is the necklace occluded at any point in the video?.. These are just some things that will effect your process of removing an object.. In this video you can see that I take a small section of our video clip and paste it right on top of the area i wanted to remove..I suggest trying to do it this way and then see what problems may occur?... I would be happy to help anyway I can.. Also to let you know, I have been developing a free blender addon called the VFX Nodes, it has a whole bunch of effects and tools and there is one called the Patch Node.. This will recreate the nodes needed for this effect to work.. If you want to check it out you can see the Blog post here: darkfallblender.blogspot.com/p/blog-page_8.html
@@DarkfallBlender Thank you so much for responding. She recorded it on her phone and she is moving way more than I last remembered haha. So, in the end, I might just put a pretty filter and call it a day. I am to newb and sadly have little to no time to spare in editing her necklace out.
No problem!. Filters are an easy option 😉.. Good luck with your project! 👍
Hello! Can i do this in a long footage? With a camera that moves unlike the one u showed though? I'm trying to edit a dvd footage and its been hrs and i can't figure out how to go forward 😅
This effect is specific, it can be a long video that's no problem but a moving camera would not be something that works well with this effect.. That being said it would depend on how much it moves and the motion..
@@DarkfallBlender I see, I guess this won't work for me then but thank you!
if camera is rotating and people is moving , try to remove him.
If the person is moving and if the camera is Only rotating! it is certainly possible ! you can track the footage and use the Track data to move a Clean plate. Then using a masking layer you can mask out the person who is moving.
How can we remove person from video if video is too shaky? Sir
I have not tried that but I would first stabilize the footage then render it out.. Then open the clean footage and just apply the process in this video..
Thank u so much by heart. If I need your help, I will ask you.
Whenever I add video clips, the flip upside down, how do I fix that?
Never heard of that happening before.. What version of Blender are you using?
yes , i have the same problem with the video given in description. but when i uploaded my own video, it worked.
When I rendered out the video, the patches didn't get tracked forward.
Hey Ethan, Just to let you know I have been developing a Free Blender Addon called VFX Nodes.. It has a whole bunch of nodes already built and one of them being the Patch Node.. With a single button it will add a node that will do all the (compositing) Work for you.. If you want to check it out you can see the blog post here: darkfallblender.blogspot.com/p/blog-page_8.html
Otherwise, I would need to see your node set up and have a look..
@@DarkfallBlender I tried it again and it works now.
👍
@@DarkfallBlender If I press Ctrl F12 on my keyboard, it doesn't render out the animation.
Can you please give me some tips on how to fix this if you can?
how do thw blender know that's a boy behind this guy ?
