Hi,
As always thank you for taking the time to reply. The update is very good.
The problem turns out I think is compositor cannot feed into to VSE.
Blender Frenzy give a good explanation of blender processing.
ruclips.net/user/attribution_link?a=rGY9FGHnp-cVyljD&u=/watch%3Fv%3DK1DTr0Nt39g%26feature%3Dem-comments
I do not know if I have found the best answer as it a little messy.
Have a blend for each part that needs compositoring -> out to pngs RGBA
Finally have a blend as a vse project, this can have a scene for each of the previously processed blends / pngs ) and bring each of the components into a final video.
Ive created shell scripts to process each blend which reduces human error and makes everything repeatable and runs blender in batch mode. Another reason for this is for some reason my pc has problems processing a clip >> 7000 ( dont know why, it has 80G of Ram, losts of ssd etc etc, blender 3.1.2 -which seems a bit buggy so may go back to 3.0.1 ). Using a script lets me cut the processing into 5000 frame chunks. Also it lets me use unix background etc etc.
It is messy but so far seems to work. It would be nice to just have a single blend for everything but I cant make that work.
Thank you again, your help is greatly appreciated.

Nice! Very clear and easy to follow. Just the right level for someone like me who has some experience with paid FX software, but wants to go to an open-source pipeline. This is a hobby for me, so my financial manager (wife) appreciates it when I can spend less! :-)
If I could add to the discussion, here are a couple of additional things that have worked for me, when shooting green screen:
If you have enough lights and room to put the screen further back, you can light the screen separately, which can really help in making it even. Also, it allows you to use more dramatic or shadowed lighting on the subject (if it works for your scene) without also causing shadows on the green screen.
For the high frame rate - some cameras allow you to change the amount of time each frame is exposed independently of the frame rate. Kind of an advanced topic, but there is information out there on how to do it if your camera is capable. By making the exposure time on each frame shorter, you get the same effect (sharpness during movement).
Finally - you can get some cheap spring clamps from a hardware store and use them to clamp the green fabric to something rigid at the edges in order to smooth out the wrinkles. You can, for example, drape the cloth over a wide bookshelf if you have one, and then clamp the edges to the sides of the shelving. I actually have three loaded bookshelves I can line up for the purpose. Just make sure they are weighed down with actual books so they can keep the tension on the screen.
Anyway, great video! I look forward to more!
Awesome! Thanks for the info. Good tips!
Well presented, well done. An excellent level of detail to get a beginner level project going, but also enough well explained detail to do an ambitious project.
Thanks!
Thanks a ton for making these videos. I haven't found any other channel that explains blender so perfectly.
Thank you!
Wish I had found your channel sooner dude, it's like the blender university. Thank you so much for the awesome 👌 content
Your most welcome!
this tutorial is a treasure, first when you see the chroma results you probably think: it´s not astounding, but when you go trough the process you discover a lot of possibilities and resources and that makes it too valuable, thank you dude, this is pure gold. I wish more tutorials were this deep about visual stuff.
Glad you enjoyed it!
Loved your video editing tutorials were really helpful
Glad it was helpful!
Been looking for something like this for so long. Thanks! I guess an image sequence it better than nothing.

Thanks a lot that really helped me ❤️
Glad it helped!
And what I keep reading from fairly rational people on these forums, confirms how I feel. Looks like a lot of work to learn something that is glitchy, takes s-loads of time to render small segments, and is basically a matrix full of dead ends. This is the first time since I started into Linux OS's years ago that I'll say this, "I can't wait to log onto windows and do my project in MAGIX. I thought I'd give Blender a try but I don't have the effen time.
sorry its not working for you.
Very good content! Thanks!
Thanks for watching! although I made an updated tutorial on this, that you might want to check out. Link is in the description.
Thank you very much! As a complete beginner to green screen in Blender, this was the only tutorial out there that I could really follow. Learned a lot about nodes too ^^ The only problem I have is that a somewhat yellowish outline around me stays, no matter what I do. It also stays when I follow tutorials about keying in After Effects, so I think it's maybe just a problem with the footage? I filmed with a somewhat "old" DSLR, a Canon 70D, which can only do FullHD, no 4k, and wore a red hoodie. Even in the untouched footage you can already see that there is this yellowish outline around the edge of the red before it goes into the green. Is it possible that a slightly noisy FullHD is just not good enough to work? ISO was up to 640, which is not too bad, maybe I need to somehow get more lighting to be able to put the ISO down. Any experiences?
Hmm, I'm not sure why its doing that. Maybe try to adjust the color ramp to make it sharper, or also, you could turn up the Pre and Post Blur.
Thanks for watching!
You can save audio in opus. It works fine with youtube, and also better quality than aac and mp3.
Cool thanks! I will try that out.
@@RyanKingArt Thanks for the tutorials. You can also try to use container Matroska and video encoder VP9/WEBM. It has better quality and less file size. Also, work with youtube. But it can be slower in the encoding process.
@@simon215a Thanks, I will check that out.
спасибо
You are welcome!
Thank you for such a valuable tutorial.
I face an issue in masking. While I move the playhead forward in the timeline to ensure that no part of my subject is out of masking, after a certain period my RAM runs out and the blender is crashed. Can you suggest how this issue can be be dealt?
Hmm, not sure. How much ram do you have?
Thumbs up for Linux Mint!
Yes!!! Linux rocks! : )
Hi! Great video! Any idea why I dont have Matte option on my addons? Thanks so much 🙌
Hmm thats odd. You don't have the Matte plug on the keying node?
@@RyanKingArt thanks for the attention :) acctualy I instaled blender twice now and dont have any Matte addon... no option for keying :( I was surprised and thought I should instal It (that it was not standard) but also coudn’t find on the web... very frustating and having to key outside blender... any thoughts? Stay safe!
@@i.a.n.x8720 The keying node Isnt an addon. Its built into Blender. So I don't know why its not there.
I dont have a compositing tab
could you please share how can I use Confetti effect in my video in blender ... ?
Thank you . Looking forward for your reply.
Thanks for the video idea. 👍
@@RyanKingArt please make it 🙃....
The parameters for the keying-node can be animated by keypoints, i think. Can this be used to work on altering lighting situations?
Yes, That should work 👍
@@RyanKingArt I have had a project about 2014, i wanted to film my hand moving in front af a blue/greenscreen and then simulate putting the hand in something fluid, showing bones after that...
I had created a Basic-program (Gambas unter Linux) to calculate the color keying. This program works with TGA-files (uncompressed) and creates TGA-files, and has abilities to change parameters for keying with keypoints. I today "found" this basic-code and tried to get it to work again, so i got to your video. With blender of today, the program is not needed anymore, i believe... But i will restart my efforts creating such a video...
I am not the artist, more the technican... Just fun to make such things... in Blender 2.79 at these time... I have switched to 2.85 not so long ago...

hi, what about superimposing videos?
like having 2 videos one on top of each other and "masking" them, one example is showing top half of the screen from the video above and bottom half the clip below . (ok the mask will have to be more complicated rather than half and half..)
Yes, you can do that with Blender. Maybe I can make a video on it sometime.
@@RyanKingArt that would help a lot, i kept googling and couldn't find much, regarding Blender. Thanks!
@@petrescubogdanandrei6486 This is actually very easy to do with Blender's Video editor. Just add in the videos you want, and then use the transform settings of the strip, to move it around. You can even animate the values, by Pressing, i, with your mouse hovered over the input. Also, you will need to set the Blend type to Alpha over, so that you can see both of the video files.

@@RyanKingArt well this sounds like picture in picture?
i would like to have both clips "fullscreen" and show an area of the clip above "on top" of the clip below; both clips playing.
I still must be missing a step or something it’s on RGB it’s on PNG Everything seems to be correct but I’m still not getting transparent frames when I render the background is white instead of transparent I just don’t know what I’m doing wrong
Rgba I mean It is on our RGBA
OK I think I figured it out use alpha box wasn’t checked once I check that it worked
@@Valuvsn Ok Cool. Glad you fixed the problem.
Yes. Don’t where green colors whilst green screening
Nonetheless, this’ll help when I’m editing future videos!
👍
Something that I am having a hard time understanding when I watch the Blender tutorials is all the extra steps/running around it takes to do something. Other software allows you to key a video right on the timeline and drop something below it and its done. It is always required in blender to isolate a clip, bring it into a new workspace or .blend, perform the edits, render it out, then bring it back? I would rather just edit it in the current timeline and keep moving. Are the workspaces connected? I am so confused
Hmm yeah. You might be mixing up Blenders Compositor, with its Video Editor. The Video Editor is completely different then the Compositor. I have not used other Visual Effects software so I don't have anything to compare with Blender. I don't know how other VFX programs work. As far as I know, Blender's Video Editor does not have any features to key out a green screen. So you have to use the compositor for that. Hope this helps.
@@RyanKingArt Thanks Ryan! Do you know how to take the output from the compositor and put it back onto the timeline? Or perhaps apply the tracking from a motion tracking workspace onto a clip on the video editing timeline?
@@jakewestin4176 Sadly, I don't think that is possible, unless you render out the frames as an image sequence, and then add them back in.
@@RyanKingArt Thanks!!
Can you supply the blend file in the description?
I made this tutorial a year ago, and so I'd have to dig around in my old files on a different hard drive... and I don't know for sure if I even still have it. Sorry. I'm considering making a new and better green screen tutorial though, so if I make a new tutorial, I will try to provide the green screen blender file setup as a free download.
I have watched all ur tutorials. They are awesome like you😋. But I am struggling with typewriter effect and lower third in video editing. Please make a video on that also. It will be great help. 😊
I will consider it. Thanks!
@@RyanKingArt Thank you so much
@@mohammadashu8984 I think I could make a tutorial on how to make a typewritter effect. But what do you mean by, lower third in video editing?
@@RyanKingArt I mean how to insert motion graphics in videos.
@@mohammadashu8984 Ahh ok. Hopefully I can make a video on that.
What to do if my green screen video is 10-15 min long, asking for some help here 😅
You can just do the same thing as I do in the tutorial. Just make the end frame longer to match the video. And it will take longer to render if your video is longer.
Any advantages of using blender to key than ae or fcpx? seems harder
Yeah, those other programs might work better. I just use Blender though. That's the program I use and teach with. : )
I started composting with blender and this tutorial was very helpful learning nodes.
Just looking for a reason to eliminate working on 2-3 apps at once hehe hence my question. Thanks anyway.
Just looking to get into blender and wondering why you’d do the keying in blender as it seems easier in after effects. Can you import keyed footage into blender?
Yes, You should be able to import keyed footage into Blender.
I do the Keying in Blender, because that is the software that I use, and teach. I don't use after effects. Also I don't think it works on Linux.
@@RyanKingArt Fair enough mate, thanks for the reply 👍🏻
Hello Ryan, I'm taking Environment Artist course in 3d Blender. However, ones I design a set in Blender and take an actor from my Green screen and he is walking through a tunnel, which is created in Blender and that tunnel has blinking lights, to add lights onto the actors face, how will that be accomplished easily in blender? or would i need to use external lights, while the character was on green screen? I hope my question makes any sense. Thanks...
You could use external lights, to get the most realism, or you could mask out an area on the characters face, and do some color correction, and maybe even add a glare, to make it appear that the light is reflecting on the characters face.
@@RyanKingArt Thank You, you for your immediate reply my brother! Greatly appreciate it! I hope one day, in this life, I'll be a blender expert like you...
Sir, I've created a tunnel with lights on the ceiling. Do you have a tutorial, where I may able to find out how I may put real life character in there? Or may I send you the tunnel which I've made in blender and maybe you can show us how to put yourself in there with a help of a green screen? Please help...
Hello
Hello there!
I always lead back to you
Lol, thanks. : )
After getting all the settings correct for rendering out transparent images when I go to render what’s supposed to be transparent is either black or white do you have any clue where I’m going wrong?
@@Valuvsn Yes, its because you need to render the images as PNG's and also set the color under the PNG, to ARGB.
A, standing for, alpha. That way you are telling Blender to render the images with a transparent background.
Ok I thought I did everything right. It rendered out transparent but it only rendered like 2500 of 14500 for some reason. Ughhhhh Also my transparent video it’s not rendering out with audio is that why you put the raw video underneath of it? I guess what I’m asking is is it normal for the transparent PNG to render out with no audio
@@Valuvsn PNG images, don't have any audio data. They are just images. So yeah, they won't render with audio. You will need to add the audio back in, in Blender's video editor, when you add the image sequence.
help, my preview just got really tiny and i cant see it
Hmm. It might be because you went too far on the timeline, and your footage ended.
@@RyanKingArt yeah i just made an new file
@@RyanKingArt i moved around the timeline and it was all tiny
@@toybonniesfm Hmm, Sorry I don't know why its doing that. In the compositor, you can press V, and Alt V, to zoom in and out.
Changing the background is one thing but how do you add a subscribe button over your videos that came with a greenscreen ? I can't figure it out and no videos seem to help. They are all about the background. I the subscribe reminder on fivver and its HD mp4 with animation with a green screen and wanted to overlay it on my video in blender.
If the subscribe button has a transparent background, you can add it in at the end with an alpha over node, and mix it together with the final video. You could also just add it in the video editor.
Hi,
Thanks a lot for the video, it's really easy for me to follow it with no real editing knowledge.
I've been following your tutorial for a timer with a transparent background I want to put on top of a video. I followed you until 11:53, after which I skipped to the saving the images part. When I click on render animation, it just shows me a cube, and I wanted to know where I went wrong. Could you help me out?
@@RyanKingArt I do have a compositing node (which is the one already given with the render layer node), but it's not connected to anything after adding the "Keying" node which makes the background transparent. I tried deleting the Render Layer node, but after clicking Render Animation the output changes from a cube to just a black screen. Also, the used nodes button is checked when I render. Perhaps I'm messing up with how I've connected the nodes?
@@komalapte6783 Hmm, make sure the Viewer node and the Composite node are connected to the final output.
@@RyanKingArt Hey! I tried it again today, and I realized that I wasn't connecting the output of the keying node to the composite node, so my main issue is solved, thanks to you! But now, when I add it as an image strip when video editing, it ends up playing it backwards. I've made sure that I'm not accidentally playing it backwards. Do you know how to fix that? I'd also like to mention that the images are being stored in the correct order, so 0001 is the first one, and 0100 is the last one.
@@komalapte6783 Hmm, I don't know why its going backwards, but in the strip settings, you can tell it to play in reverse, and that will switch it, so it play forwards. In video editing, on the right side panel, its a check mark button, called, Reverse frames, Under the Video Tab.
@@RyanKingArt Yes when I checked, it's apparently playing from 0100 to 0001. I further checked and realized that it is actually about how you sort the image arrangement when uploading the images. Mine was from 100 to 1, and that was what the issue was. Thanks a ton sir, you've helped out a lot! Most youtubers don't do this, so I'm grateful you've taken the extra effort to teach beginners like us some editing. Thanks once again :)
I wish I could find a green sheet somewhere :((
Yeah that would be helpful.
ok it does remove the green screen but i'm trying to edit out the greenscreen from an effect but it completely removes the entire video without leaving anything
Can you explain more what you mean by, An effect? Are you using some stock footage or something?
@@RyanKingArt like a greenscreen video i'll link it here : ruclips.net/video/ZkNguRlF6SM/видео.html

Hi Ryan King. When I get to rendering the images out as PNG, with the RGBA selected for some reason I end up with the images of a black background anyway. I was wondering if you know what my be wrong here. Thanks
Hmm, it probably has something to do with the compositing nodes. Make sure that the color value on the alpha over is fully black and transparent.
@@RyanKingArt. Yea I checked to make sure it was fully black. I also made sure the film was on transparent too. I don't know if it is because I am using the same saved files. When I did the tutorial I had no problems at all with this. Maybe I will open a new project and start afresh and see if it works. Thanks for helping
@@exploringbiblicalendtimes779 Hope you figure out the problem!
@@RyanKingArt Hi Ryan. I figured out the problem. In the layout tab window I forgot I had a plain in front of the camera. I deleted it and rendered out empty space for the render layers. And now it is fixed hahaha
@@exploringbiblicalendtimes779 Oh good. Glad you fixed the problem!
Blender is a very heavy program
Yeah, it kinda is.
Does anyone know why when I hide my raw video I can't hide the video but keep the audio? Also, my playback is slower even though its the same footage with the same output settings... Any ideas?
Hmm. Your in the video editor right? The dark blue strip is the video, and the light blue strip is the audio. Press H, to hide the selected strips, and Alt H, to unhide them. In the playback settings, you could turn on, Sync to audio, or frame dropping. That might help with your lag.
@@RyanKingArt So now I am having a problem where my image has a black background even though I set the alpha over node to transparent and rolled the scale down to black. Any ideas? I am using 2.92.
Hmm, when rendering your images, make sure you have them set to PNG, and below that, make sure its set to RGBA.
@@RyanKingArt Thanks for responding, but yeah I did all of that. My problem is I am taking my footage into another scene and bringing the image as a plain and it has the black. I found a run around with changing the format to quick time among some other things and just hoping that it doesn't have other problems down the road.
Sorry I didn't see your reply! RUclips didn't notify me. If your using the images as planes, your going to need to go into the material nodes, and set it up with a transparency. Add a Transparent Shader, and plug it up with the principled BSDF with a mix shader. Then plug the Alpha of the Image, into the factor on the mix shader. Also, are you using Eevee? With Eevee, there are a few Settings your going to have to change to make the transparency work. Let me know if you need any more help, and I will try to help you.
So I thought I had this all figured out. Looked good on my screen. Then I rendered (transparent background) and ended up with a bunch of transparent pngs. I was gone. 🤦🏼♀️ Guess I'll have to try again and see what I skipped. 😅
Ahh ok. Hope you figure it out. : )
@@RyanKingArt Thanks so much! I finally figured out what I was missing. :)
Of course then I couldn't figure out why my backround wasn't showing. Then I realized my blend needed changed.
THANK YOU so much for putting out these videos! I've learned so much!!
If my channel ever starts making money so I can afford it, I'd gladly support you more, lol.
@@HomesteadingWestVirginia Thank you very much. : )
can anyone tell me why my video is cropped after rendering? :(
Loved it! Subbd it😁
Thanks!!
Aint ware wear 😂 just trolling great video watch it a million times i personally made this viral
Haha yeah I'm so bad at spelling. 😂
it always renders a cube for me how can i fix it
In the compositor, delete the Render Layers node and add your video footage in instead, as either an image node, or a movie clip node.
Hi
I have created a few scenes
1 - movie
2 - Intro - which is a scene containing an image seq and a bg colour
3
- Presentation - Which is a compositor of image seq plus various
filters, green screen removal , colour correct a couple of tracked masks
etc.
When I play Presentation Scene in Compositor all looks good.
I change to movie scene and and Video Editing.
I add the Intro scene it works no problem.
So now the movie scene is vse and has the intro scene added.
I add the Presentation scene to the movie scene in video seo and get a black screen .
I have selected sequencer as the scene input.
It is set to alpha over , everything else is defaults and also look to have the same values as the intro.
The only difference between into and presentation, is intro is a vse the Presentation scene is compositor. It has viewer and composite as outputs.
The layout, default cube removed. Cam set to origin, with alt R alt S etc then a g Z to move it above the base.
As a test, I rendered out the Presentation scene as pngs and it works file.
Does anyone have any ideas what I am doing wrong ?
Thank you for your help.

Hmm, did you make sure to set the output to RGBA? If its only set to RGB, then it won't use the alpha channel. So make sure its set to RGBA in the output settings. Also, I have an updated version of this tutorial, which is a lot better. Links in the description.
how to resize the person in green screen?
You can use the Transform node to do that.
@@RyanKingArt Thank you very much
Learn something with MAGIX and come back to it five years later and I can still do it. I learned Chroma on this pile of crap Blender Video Editor and it worked like a joke, and one week later I can't find my way back to it. Why does it have to be made this complicating? All these pull downs and switches and checks and windows just to get into something simple. Does anyone know of a Linux equivalent to MAGIX or something close that's better? I'd actually pay money.
sorry you don't like it
@@RyanKingArt Thanks, I've calmed down since then, after installing "shotchut" and "kdenlive" and did chroma, cutting clips, margin setting, rendering, everything I found easy to learn and all I needed. OMG they're even easier than MAGIX. (Why Blender has to be hard and weird I don't get).
remember: this is blender
you cant have blender without it being too confusing than it needs to be
Sorry if its too confusing
@@RyanKingArt its not you, it's just blender in general. whether it be animating or modelling the software just needs to make it way more complicated than it needs to be

Haha yeah I spelled it wrong. I have a link in the description to my more updated green screen tutorial if you want to check that out.

Nice!
OMG do if you're going to use Windows 10 or greater why on earth use Blender Video Editor for anything. I've had MAGIX video editor for 20 years and taught myself on it to do things that are a real pain-in-the-ass struggle with Blender Video Editor. How can this be better? I'm spoiled with what I have I guess. The Chroma Key is about 1000 times more complicating and harder to master, with many more moving parts and functions to make the same thing happen. Why do so many people Linux experts advocate this?? I feel it must be because they really have never had a passion for making actual video stories, at least like short films or something, and just make it work enough to do a few simple strips on a timeline and go, "COOL!!" They probably never use the Chroma features or other more in depth. things. MAGIX was not a struggle to learn and with ease I can do more than this pile of crap. This thing is just one small step above writing it all in code to get what I want instead of pointing and clicking. Terrible tutorials. Oh yeah, like Eclipse IDE, same kind of brute force learn, it's free. Thank god I didn't completely give up Windows and I can still fall back on MAGIX to get the job done. It would have been worth the $96.00 that Fry's wanted two years ago and yet I got it for $15.00 before they closed for good. Works great. I don't sell for MAGIX. I wish I did though.
ok
