Transparent Video in Unity?

[gritty nexus]

Hey Guys, so I made this video in After Effects with a transparent background. I rendered the video in .AVI format with RGB + Alpha Channel, now the thing is I need the video in VP8 (.Webm) format which is not available in After Effects, so I import the rendered AVI into either Adobe Media Encoder or Premiere Pro but whenever I convert it to VP8 (I enable the "Include Alpha Channel" option) the video has this artifacts as shown in the image. I have tried converting to VP8 .Webm from several different formats with alpha channels but to no avail, What should I do?

Note: The reason I'm trying to get .webm working is because I have tried to Apple Prores 4444 format but it simply doesn't drag into my video player component (I use Windows).

mybe try doing it with a greenscreen

and then doing it with the croma key in unity, I always solve it like that, when I want a video to be transparent

How would I chromakey it in Unity?

Have u checked if webm supports transparancy

[gritty nexus]

Webm does support transparency, in fact I am able to convert it using shutter encoder and it gives me a transparent webm, though the problem with Shutter Encoder is it really lessens my video’s quality (7 GB AVI to 1.5 MB .Webm).

You need the shader

and follow the tutorial then

So I’ve also seen another approach online with the shaders where you plug make a separate render of just the alpha layer of the video and then use that in Unity to create the transparency. Do you think that will yield better results or is easier to do?

I don’t even know

I can just tell you I did it this way and it worked out fine for me

Im sorry

No worries, what video format do you use?
