> 2. There is a problem with transparent quicktime videos. These are quite often used as source video files for various VFX (for example, I've bought Action Essentials 2 from <a href="http://videocopilot.net" target="_blank"><a href="http://videocopilot.net">videocopilot.net</a></a>). It seems that in some cases Blender isn't able to read the alpha channel from quicktime video.<br>
<br>
</div>When you speak of "transparent Quicktime videos" you are actually<br>
talking about a wrapper with a codec inside. I'll make an assumption<br>
you mean an h264 via an MOV with an alpha channel.<br><br></blockquote><div>The quicktime 'Animation' codec (lossless, similar to png) supports transparency - it worked for me many years ago but I haven't tried it lately. Other than blender now not understanding it, perhaps if ffmpeg is reading the quicktime file rather than the quicktime api, it may not support it.<br>
