Rotoscoping Tips in Blender
Вставка
- Опубліковано 18 сер 2020
- Rotoscoping often gets a bad rap because of how time-consuming it can be.
In this Blender video we break down some tips on how to streamline the process inside Blender, and open up a whole new world of compositing possibilities.
We'll start by creating a basic mask around a part of our footage we want to keep, then refine that mask, and animate it to complete the rotoscoping process. We will then utilize the set alpha node to give us a usable piece of masked footage to comp in wherever we want. The power of video transformation now lies in your hands. Enjoy!

Whoa, a 1,000 views in an hour! You're all amazing. :) 🍪❤️
I guess distributing this on CG Cookie as an established large channel over your personal channel has its advantages.
You are another level dude.. that is why.
Hey CG cookie, can you please tell me how to zoom in nodes in the Blender compositor???? Because peering at those small nodes gives me a headache......
U r breathtaking
Great tutorial
No joke yesterday I was searching youtube to see if anyone has done exactly this with rotoscoping. Thank you so much!
Yay! Our mind-reading experimental helmet IS working... ;) Happy Blending - Wes
The idea of separating the body parts is insanely intelligent.
The more I use Blender the more I am in complete awe of all the things it can do. Had no idea masking was this simple. THANK YOU!
This is by far the best rotoscoping tutorial I've seen for Blender on UA-cam. Thank you so much for sharing your knowledge, this was immensely educational!
I wish blender get some AI powered tool to rotoscope just like Adobe's Roto Brush
Perhaps manual Rotomation would be a better alternative. You could just manually animate a 3D Model over an object in the original video by hand, and overlay the original object from the clip onto the model
There actually is a machine learning masking addon that i had checked on github if i find it ill link it here
@@RhysJosmin is there? Please
@@imyasharya huh? i didnt get your question
@@RhysJosmin I mean to say if there's any add-on, please provide the link.
Wow, really good job running us through this. As someone who's new to Blender, when I watched you pull up the nodes I was about to feel intimidated, but you did a great job explaining this so even I could understand. Props!
This was really helpful. I'm learning a lot a bout VFX, rotoscoping, Blender, etc and this was very detailed and informative
This tutorial has easy answers for problems I was struggling to find out!!! Thank man!
This was exactly the tutorial I needed right now. Thank you.
This was the first time I saw one of your videos and I loved how you did it. Quick, to the point, no bullshit. This was exactly what I needed.
Fantastic tutorial! One of the best I've ever seen!
there's several things at the beginning of the composite tab step u didnt mention. can stop a beginner in his tracks. like how to get the clip ur using as a background set up.
excellent tutorial, thank you very much
There are certain people that illustrate how to use particular programs very well, without a lot of unnecessary crap.
Kenan Proffit is to Blender, what LogosbyNick is to Inkscape. Outstanding tutorials.
Searching for this video from ages finally got it
This is amazing! Thanks!
Great !. Just what i'm looking for
Hey keenan awesome stuff
great video. thanks man
Actually, I wish there were more tutorials on how to do rotomation by hand in Blender. That could be a good alternative to Roto. You could just manually animate a 3D Model over an object in the original video by hand, and overlay the original object from the clip onto the model
What? I mean how?
@@ayushtiwari2873 Well in terms of animating the model over the object without camera tracking, there is one tutorial that teaches that
openvisualfx.com/2019/10/04/matchmoving-by-hand/
I'd love to have more tutorials like that myself
The Colorization Channel Not a good solution - matching edges in 3D is far more work than doing it in 2d. Why make more work for yourself if you don’t need a 3D object?
@@aliensoup2420 Well, in my case, what I want to do with Rotomation is that I have created some semi-photo realistic 3D Models that I want to use to colorize a piece of black and white footage with. Mainly a scene from an old Doctor Who episode (which the majority of video colorizations on my channel are of).
I already have a fairly effective process of keyframe interpolation using a code called Deepremaster. However, it doesn’t really work well for extreme movements leading me to create more keyframes, so I am using Matchmoving techniques to compensate for where I possibly would’ve had to rotoscope by animating thousands of polygons over objects in the original footage.
This brings me to the reason why I chose Rotomation and Matchmoving instead of simple rotoscoping. The reason for this is because unlike Rotoscoping where you have to animate dosens of masks in order to get a more realistic detail, Rotomation and Matchmoving may inevitably compromise by allowing me to animate simple models which while not intended to be hyperrealistic, I intend for them to have basic detail that may add to the realistic image such as subtleties on the skin tones. And because of this, I don't need to animate thousands of polygons just to get good detail.
The footage itself is about 480p in quality, and a combination of low quality with the fact that it's in B&W makes camera tracking/solving, and all of the other things people use to do traditional matchmoving impossible.

I wholeheartedly have to thank you, sir, for the simple reason of having thought me a term that properly describes what I've been doing (or at least, trying to do ) for ~5 months now;
*_Rotomation_*
I, finally, have a search term that'll almost certainly yield better results-thank you!
thank you very much, great video.
Thanks!
thanks man it helped a lot 😀👍
Cool! Thanks!
Thankyou somuch for sharing
Awesome, Thx !
Thank You!!
muchas gracias amigos
The character looks a bit to small to me in relation to the background, or maybe its because the two pieces of film have been shot with different camera setups, its not perspective matched? Still a good tutorial though
Yeah I think so too. He just showed a broad overview, as he said.
It's the relation to the car that feels off. Technically I think that car is closer to the lens and it's shot on a long lens which makes the background appear bigger.
execellent breakdown :O)
wow I still wonder if you manually tight wrap those mask yourself though. looks pretty tight for a manual work. kudos!!
Awesome, thanks for the video. You know how to structure howto videos!
Nice Work
I'm fairly new to Blender, in that I only play around with features experimentally. So as awesome as this video is... You only had me for about 3 minutes before my head exploded 😁
Exactly. Way too complicated. Way too fast. Explains fuckall. Leaving me completely frustrated and annoyed.
Hmmmm... rotoscoping, never knew what it was called, but I've been trying to do this...thanks!
I wish we had more blended videos for vfx stuff. Tbh its the only thing I'm really interested in
Bro you're SICK how long you been doing this? also how long did it take to get this GOOD!!
nice one
Nice!
thank you for this! I have many people in the shot but sometimes that one has to walk behind someone. How can I make sure of that? Which node do I have to add?
How did you make the individual masks? It appears those masks are traced exactly along the outline of your body parts. The larger mask you showed us has a margin around it. Or did I miss something? As always, a great tutorial! Thank you.
Would it be possible to rotoscope it in after effects, and then add it back to blender ?
Given how good the rotobrush 2 is now ?
Can you please make a video on retopoly and how to work with it ?
Hey ya
could you do another one of these with the newer version? alot has changed and its a bit confusing
A w e s o m e
Great tutorial
Extremely useful
A very good and chuncky video😀
how come when i'm compositing and hit play on the playback the video is just a still image and doesnt animate? when i hit stop it just all of a sudden jumps to the frame it should be at but nothing moved during playback.
@CGCookie awesome video brother, thank you, I was able to use a Video background instead of a "Static Image" of a parking lot in your case, in your example your background was static and and the "mask" was moving, this the tracking component was not required, in my situation I am seeing that the mask needs to be adjusted exactly over the "x-axis,y-axis,rotation, and scale" using the "Transform Layer" over the area on the video where this mask "Alpha OVer"lays, Is there a way I can attach [PIN] using the "Parenting Object" the mask over the video background ?
Now someone tell me Blender is ONLY 3D Software :D
I can't. :)
@@user-ip1uz2vj4m I understand :)
Blender is only 3D software
Is there a way to render out the mask as a transparent background and add it back into another blender scene. I have accidently did my Roto separate from my full movie edit. (new to blender)
Hello, every once in a while I return to this. Blender has a new version right now and I'm wondering if maybe there is an easier way to roto since this? Is there maybe a plug-in or a way to auto roto that one can do linux?
Do you actually prefer doing it this way over using the rotobrush in AE?
This is really cool, can we do something instead of that long journey of masking? Like something to detect the contrast between colors inside the big mask...
Green screening. You must have seen a movie (or making of video) where someone is walking pushing a green sheet on wheels behind the character.
And use the Matte nodes in the compositor to select and remove background - not masks.
@@neilmarshall5087 thank you👍🏻
@@kushalchahal2480 Probably with a mask that is parented to a motion track of the character. Standard rotoscoping.
In movies they remove everything that is not the character- and the cameras position is tracked. That is the big long arms you see cameras on in 'making of movie' shots. The background is put back in again - filmed with a real or a cg camera that follows the same path as the original camera.
@@kushalchahal2480 for that you can use a simple mask that doesnt cover the actor but does cover the greenscreen man. It can be very simple and done within a few mins
@@kushalchahal2480 you can keyframe the mask or track the camera and parent the mask to it
Could you use the masked element as an object in a 3D scene?
amigo y se podria hacer la rotoscopia en after y luego abrirla en blender
Dope tut I learned a lot but I cant help to think how I’n AE I could’ve done this in 5 mins.
i think that the silloutette is enough to make me consider learning rotoscoping
How do I adjust the 2 movie clips so that they are synced the way i want them to be?
You said we can treat it as a layer, how do I put it in a 3D scene I'm making? It doesn't show up in my scene collection spot..
I have used this tutorial to refresh my rotoscoping knowledge in Blender in the past. I don't do much rotoscoping.
But, for some reason I cannot get 0:27 Ctrl-LeftClick to do anything in Blender 4.0.1 to draw my mask.
How do I get the Transforms and Mask Tools stuff to show up? All I have is a tab thing that says Annotation and there's no button to change it on the side.
I thought the wall was somewhat like glass, so you had to compose the glass over the legs, but i dont think this is possible only with composing...
Super avsome
Rotobrush in AE would help too! :>
People who don't want to spend money on a AE subscription can do it this way
Never knew blender can do roto😱
pls show me something that blender is not capable of :D
@@kushalchahal2480 than use ae's new rotoscope 2.0 :)
@@kushalchahal2480 there's many ways to crack it tho^^
I followed the tutorial, but when I launch the test render, my silhouette is all black. There is no image of the actor. Why? Is there any particular setting that I forgot to put in the Mask section?
🤝
Please help. My exported video do not show any of the masking :(
How to render the animation? so you have to save 1 image by 1 image then make an animation manually?
Did you know the answer yet?
Great video but these nodes. How do u know which ones to use. U make it look so easy. Still don’t get nodes. Arrgghhhh!
you are boss
you lost me at the nodes... Any way you could go into more detail or slow it way down for beginners. Does anyone have any suggestions where I can go to get help with that?
---- V2.91 - Before, Blender was mutilating the mask bounding box on some frames randomly. Now it looks like it's masking my mask on some frames, leaving some parts of the masked object transparent. Other frames are rendered rightly, as seen in the 'masking interface' in this sloppy test vid. Why?
Screen capture (I have the mask set 'absolute'---I don't know what 'relative' does----I didn't bother with the 'node' trip):
ua-cam.com/video/yyiKczL6O20/v-deo.html
thank you for this video but im lost at 3:29, the compositing parts, sorry im new to blender
found the solution, had to change the "render layer" node to "movie clip" node and to view video above the "scene" tab, change the editor type from "outliner" to "image editor"
but my video didn't sync with my mask and didn't play properly, I had to pause every frame for the video to "play", any fix?
oh the mask didn't fit because i have to change "relative" in scale node to "render size"
now the only problem is the video don't play properly
did u figure it out? when i hit play the video doesnt move. its just a still image. although when i hit stop it all of a sudden jumps to the right frame.
Is it possible to make it even better? I mean, if I spend a day on it, or even 2? There´s too much flicker, and edges look too soft. A serious VFX department would hardly approve this for a feature shot, so can you make it even better without needing to use after or mocha?
A serious VFX department would be working from green screen for anything important unless someone screwed up and they were trying to salvage as shot that would be expensive to re-do in which case they'll probably have to accept some compromise.
Help please! I did the same tut on my videos. But when I render it nothing of the compositing work appears
Did you figure it out? You have to render it as PNGs and select RGBA, i.e. RED GREEN BLUE ALPHA, you need the ALPHA channel rendered. Thats how I did it anyways from this tutorial ua-cam.com/video/J1PS5ZtgXqw/v-deo.html&ab_channel=intranetgirl
Can you please show me how to get my video on the mask-sequence? Because i open mask while using video editor and the clip i want to mask does not show up. do you know why this happen?
Did you forward your clip to the first frame? I had that same problem. If you move your timeline to first frame it should work. Hope this helps.
I was trying this from youtube. But I didn't got it. Tahnks alt+ ❤️
What the hell bro?
When I go over to the compositer (3:28) there’s nothing there, so I can’t add any nodes. Is there a solution?
I had the same issue, you should check the "Use nodes" box.
Oh ok, thanks so much!
Same thing for me
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.
ive pretty much followed this exactly, yet when i try to render it says i need a camera?
+1
Damn i cant get my nodes right. All i have is a movie clip with my characters shoulder being hidden by some 3d objects. I want to have his shoulder pop over the 3d objects. I roto it perfectly but i just cant get the nodes right. Watched every video there is very frustrating.
Exporting to blender, UE4, etc ?
You trying to export it to UE4 as a video file or 3D object?
The only 3D object in this video is the front wall that was out of focus.
You could make full 3D shots or shots like this for cut scenes for use in UE4.
When I heard the name of the presenter I knew it would be packed with cool shit, thank you Mr laser eyes
how did u render that? pls help me
Have you find out yet?
@@hagarabdul4312 yep
Please tell me how?
@@hagarabdul4312 here ua-cam.com/video/tYGrP9Foca4/v-deo.html use this tutorial! in the end he teaches how to render!
lol
Blender needs more love for visual effects

Dude make a spider web out of panels Lmaoo one day I will understand .. soon!
--- Warning! - Blender 2.91 - Masking loses its mind if your mask is too complex, has too many dots. My 194-frame roto mask looked right in the Masking-tab viewer, but quite a number of frames rendered wrongly---with masks in the wrong place and shapes. Saving/closing/reopening the project brings the wrongly-masked frames into the viewer sequence. Ewh. Memory Leak? I'm trying to figure a work-around for this problem. There's definitely a limit on the complexity you're allowed to use with masking---number of dots/points, whatever, before Blender malfunctions. I haven't read through 174 comments to see if this has been mentioned.
English is not my first language...but i can easily understand your English
So rotoscoping is animating a mask?
Create Tutorial :) ..
For a fraction of a second i thought i was looking to a fusion page in davinci resolve 😅
my mask node doesnt, it wont crop my body pleasee HELP IM SO CLOSE TO PERFECTION!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
How to i export my video out of blender bruh
Have you find out yet?
@@hagarabdul4312 hell nah
Can you please make a better tutorial with more details?
Your short key instructions, like ctrl left mouse or the one to close the mask, don't work when I try.
You need to go to masking not motion tracking
This can be easily done in Ae or mocha pro💁💁💁
People who don't want to spend money on a AE subscription can do it this way
@@kushalchahal2480 nope
Thankfully after effects has rotoscope brush 2.0 Can't wait til ai takes control of rotoscoping entirely.
There is a video of a siggraph paper with magical AI things that make to obsolete
This is really just video masking and not rotoscoping which is done for animation. I see this term is being loosely used on youtube. When masking and rotoscoping to totally different things. Many of these videos are confusing the search algorithm to find actual videos related to rotoscoping in blender.
