Blender Compositing VFX Tutorial : Remove Traffic/Moving Objects from Videos
Вставка
- Опубліковано 4 жов 2024
- In this Blender Compositing VFX Tutorial, We will first create a clean plate using our video clip.
Then with a little bit of masking and some compositing we can easily remove the unwanted traffic in our shots.
You can then add some compositing with Color Grading and even some camera shake to finish the shot.
Hopefully this Blender Compositing VFX Tutorial helped! and as always thanks for watching!..

"Load up Photoshop"
- opens GIMP
LOL :D
Well I can't really say "go ahead and open up your poor mans Photoshop" can I? lol..
how is the better tool the poor mans one?
Is it better? I couldn't really comment since I only have used gimp and PDN but I know some people think of Gimp as a poor substitute to PS.. Again I don't have PS so I can't compare them but Gimp does everything I need so don't get me wrong.. I like Gimp... :)
linux > open source > better..... and even if it's not REALLY better you can crack out your coding books and make it better yourself so.... better.
I never really thought about "improving" Gimp or any program for that matter.. That is to say, coding isn't my thing but I do like the Idea of being able to write a bit of code and improving the program. Anything that can be modified and made better (In the eyes of the user. Since we all have different Ideas on whats better) is always a good thing. Again, Gimp has never let me down but others may need Gimp for things that I wouldn't so a little modification would be cool.
I didn't even know that I can do this in Blender... Thanks man :)
No problem! Glad it helped!..
Holy crap, I was up 'till two AM playing with this on old footage I was about to delete. Made a pack of clean plates for use in other stuff before doing it. It will be ridiculously useful going forward.
Sooo you found it helpful? lol... Thanks for the Comment Robert!..
Great use of background music for the tedious part. That was a good idea for keeping the audience engaged.
Thanks buddy! I try not to bore you guys so adding a little audio distraction is a big help ;).. Thanks for the comment Delta!
When magic gets de-mythed and suddenly a bight light begins to shine...! :-)
Awesome, fine tutorial - thank you thank you thank you!!!
:D I'm glad you enjoyed it!.. thanks for the comment Robert!..
I spent my whole day searching for a solution to a problem and finally found it! thanks!
Hey Speedgurke, I'm glad this helped.. thanks for the comment!..
Me too
It's not as complicated as I thought. Nice.
Yeah it's super simple and quick to execute. Thanks for the comment!!..
Thanks for taking the time to make these great tutorials! :)
Thanks to you for watching them! :D
I had an idea about how to do this, and I need to do it on a fairly grand scale for a project idea I have. I may need to mask not only vehicles or people out of shots, but also mask in wind moving around trees and stuff, but I have a pretty good idea about how to do that all now.
Hey Jeremy, Have you seen the VFX Nodes addon?.. There are the Clone Node and the Patch Node.. Both can be used to achieve this effect but much much easier.. The Addon has changed a little sint version 1.0 but if you want to check out the video I think the addon will help.. Here is Version 1.0 ua-cam.com/video/HyPSR1v6sps/v-deo.html
I needed this in my life! I didn't know it at the time but I do now!
Lol.. Well I'm glad It helped!!.. Thanks for watching..
Thankyou so much for sharing your videos are very informative. I learnt alot
I'm so glad! 😀👍
Great tutorial!! Very helpful and easy to follow & understand! Thanks!
Hey, Thanks for saying so!..
Just found this video and subscribed. I've wanted to learn this type of stuff with Blender and you have some great videos! Thanks for making these!
Hey Pesto, thanks for the support!.. I am glad you are enjoying these videos.. thanks again!
I'm curious, if the back plate was just a still image, why did the final composited clip at the end show some slight camera movement (noticeable when watching the road lines carefully)?
The Camera would be moving slightly.. If I noticed it I would have tracked the shot and make the back plate move with the shot.. That's some super sight you got there lol..
Excellent, thanks.
Glad it helped!..
Good video and really interesting, well done.
Hey, Thanks for saying so!..
You are a wizard
😄 Nope just a mere muggle.. You might want to check out the VFX Nodes, its a free Blender Addon I have been developing. It has a bunch of nodes you can add to the compositor. I think the Patch Node or Clone node would do this job much faster. If you want, you can check out the Addon here: darkfallblender.blogspot.com/p/blog-page_8.html
Very cool.
Thanks for saying so!.. I'm glad you enjoyed it :)
To produce the clean plate, I guess a median filter applied to the selected images would have worked as well and save a little work at that step (though the main work remains with rotoskoping in the video)
A median filter in blender?..
I didn't mean to say that step could be done in blender. But in certainly can in Photoshop, and with correct addons also in GIMP, or even as ImageMagick one-liner. In the end, the effort is probably not *much* different - again, the main work is in the tedious rotoskoping ...
Ah right ok ;).. I agree roto'ing an advanced object can be a pain.. luckily in this video there isn't much rotoscoping..
That's grt! Thanx 4 les'n!
Hey thanks for the comment. I'm glad you found this helpful!..
Is it possible to do it the same way when the camera is moving? For example a video at the beach turning around and you don't want to see the other people.
Hey Jan, It is possible to do what you want but it would be quite different from this tutorial. You would need to first track your footage then create a clean plate (an image with just the beach no people) then comp it together. It will help if you know the focal length you shoot the footage at, along with other info about your camera (for the tracking). You could try and track your footage and then use this method in the tutorial here but you could get problems with people moving into your "clean area" so I think the clean plate idea would be easier. (one thing I don't like about clean plates is that they are a single image, so if your lighting changes in your footage, the clean plate won't change..)
Great stuff!
Thanks Micheal!..
it's funny but nicely done
i mean blender is free and can be use for composite too...
good for those companies who can't affords composite softwares...
Hey thanks for the comment!.. Yeah, blender is amazing because there is so much you can do with it. Not to mention it's free!.. always a bonus ;)
Great Job!
Thanks!!..
what blender version is this as am using the 2.8
2.78 I believe..
super !
thx
Thanks for watching! :)
Help please. i`m following step by step and have a problem at 1:43 of this tutorial. when I select the loaded movie clip it has unappropriate scaling (i don`t see the whole scene, just a half approx.). so when i click render so the rendered image has the same unappropriate scale. i think this will not allow to finish tutorial correctly. what should i check?
Hey Evgeny, If you look at your render panel (on the right) you can see your resolution settings, make sure the resolution is the same as the movie clip you are working with. Also, right under that there is a Percentage Scale.. By default it is set to 50%.. Change that to 100% and your masks and scaling will be fixed..
You made me to sub!
:D thanks for the support!..
Hey, can you help with an edit to address overlapping objects? like a person in from of an object, Retain the person but remove the background conditioned to - When both the objects tend to move. Appreciate in advance.
Sounds like you need to Rotoscope. In the last live stream we rotoscoped a hand that was moving in front of a face.. You would need to create and animate a mask and then use it to occlude or remove the object you don't want.. But note, if the thing you want to remove (lets call it Obj. A) if it goes in front of say the object you wish to keep (Obj. B.) When you mask or rotoscope out Object A and it is directly in front of the object you wish to keep then you might have some trouble.. You may need to work around that and depending on the shot you are working on it could vary..
Yeah but what if I have moving camera footage i.e. drone footage
Then it's impossible, right ?
For a moving shot it would be much harder and I am sure it would be much different. I think it's possible but I have yet to try it..
@@DarkfallBlender it worked for me following your steps much like a moving cat
Great!
Thanks!!
Great tutorial! But, if the camera is not on a tripod and have a 3D movement (switch perspective over time), the technique will be the same?
It would be similar, You would have to make a clean plate, track your footage and maybe even lose some quality (Since you would need to scale the whole shot up)..
When you mention "clean plate", i gonna need to make frame by frame the clone process? I found it a little confusing :p
It's a complex task to do when the footage isn't on a tripod.. but like we did in this video we only use the part we want to see it would be the same in your project. In the start of the start of the video we create a clean plate (an image that has no cars in the shot) then with a mask we "Show" the clean plate in certain areas.. but when the footage is moving you would have more work to do.. You could use a similar technique where you take areas of the original video and move them to remove a person, now I'm not sure if this would help you but you might want to check it out here: ua-cam.com/video/lR89kPyPghg/v-deo.html
Thanks for the help man :)
np, good luck
How about adding in traffic? have you tried adding in a cg car?
I have not tried addin in a CG car yet, I was thinking about it a while back though. I did a tutorial where we simulate the sound of a police car driving by and it would go well with actually adding in a car..
Hi, Darkfall love this type of VFX, what I would like to do if possible is emulate this using footage of a busy mall any suggestions of how to do this would be great.
Hey thanks for the comment!.. I mean it depends on the shot and what you want to achieve but I would assume it would be the same as this. Just create a clean plate of your shot, then mask around the person or things you wish to keep and then mix the video with the clean plate using the mask as a factor.. If your camera is moving you may be in for more work.
thanks for the quick reply, what I'm looking to create is a city full of people going about there business the have them disapear, were i am seeing tha main issues is makeing the clean plates.
To create a clean plate, you need to first save out a still image then (in photo editing software) clone the background and where ever you see people. You want it to look empty.. Then for the mask I would create a mask to follow the people and then animate the factor to make them disappear as and when you require.. again this will be a lot harder if the camera is moving!..
thanks, it sounds like I have my work cut out for me. I'll see what I can do.
anyway keep up the good work.
:) I'm sure you will get it done, it might take time and a few tries but it's worth spending the time on. The results speak for themselves. Anyway, Good luck with your project!..
Can you told how to remove video background without using greenscreen like I select object by using masking and then I went remove background like transparent pls how pls reply sir
As previously mentioned, you would need to mask out (known as rotoscoping) your object and then compositing the two videos together..
@@DarkfallBlender sir can make a tutorial on it how to any type of background remove without green screen in blender pls sir
Sir can i used this method to remove person who suddeen come in my shooting video.. ?? Same process ?? Or ?? Anything different
As you can see the car appears from the distance is that what you mean?
Sir I talk about unwanted person.. who came in my video.. so I wanted to remove that..one single person.. ?? Thanks ❤️🙏🏻
If your camera is on a tripod then yeah you should just be able to follow the same steps 👍
Can you please do a tutorial on how to do this in Blender 2.8?
There should not be any differences (except UI changes).. The process is still the same..
@@DarkfallBlender I tried your steps and it didn't work.
I have tested it again and it works fine for me.. What does yours do?
@@DarkfallBlender You tested it on Blender 2.8?
That's the version I currently use.. Have you seen the Clone node I made? It's pretty similar to this (except most of the work is done for you) You can check out the add-on here: darkfallblender.blogspot.com/p/blog-page_8.html
i did it but for some weird reason there in the final output video it can see the mask a little big like a diference colour surronding the car, can u help me why? i try adding color node and other node so far still see the diference color or mask in the video
Hey Masiaf, In the render panel, make sure your video resolution is the same size as your movie clip and also that the Percentage slider (under the video resolution) is at 100%
@@DarkfallBlender thanks for you answer, so yep is the same size and 100% slider, imgur.com/zUUCiJE corner top right it can see a color more ligher on the door, im using 2.8 blender
Is your camera moving?.. It seems like your camera is not on a tripod..
@@DarkfallBlender not on a tripod but was shooting on a little stand so there is no movement of the camera, same thing happen to the car tutorial
If you see your Image node, I assume it is your "Clean plate" if you notice the image is brighter than the video.. They need to be the same color before you begin.. If you can not reshoot the clean plate, you could add an RGB Curves Node right after your image. Click in the center to add a point then slowly drag it down until it matches your video..
oh no what if the video was hand held and shaky...?
AAAAAAAAAAAA nightmare time
I guess it would depend how bad it is? For example, I would first stabilize the footage then see if it was possible to do this effect.. You may need to crop the footage also..
@@DarkfallBlender oh I see. thanks bro! you rock!
i thought this would of been hard to do!...
Pretty easy huh? :)
And pretty cool...
got yourself another subscriber too xD
Appreciate the support!
Sorry Dude. This looks totally different than 3.2.1. Maybe you should update your videos a little ?? Nothing on my screen looks remotely like yours. You're probably using a Linux or Mac version ??
Uhm, I was using 2.78 (which was the latest build at the time in like 2017) So yeah things will look a lot different.. I have done more updated videos along the lines of this effect removing objects. I have also been developing a free blender Add-on that will create these VFX tools with a click of a button.. You can search my channel for VFX Nodes or check out the blog post (links in Bio)
why are the cars so fake looking XD
...Maybe we are in the matrix?...
Either that or the Color Grading.. ;)
IrishBruse definitely because the camera was zoomed in quite a bit. the perspective lines vanish when you do that
