I have a series of PNG images that I've placed in the Video Sequencer. I want to render them as an mp4 video, with a transparent background.
I've checked the Transparent box; selected FFmpeg video as the File Format; ticked the RGBA button; selected Quicktime as the Container; selected FFmpeg video codec #1; gone to Render Animation...and the resulting video cannot be opened with QuickTime Player ("file isn't compatible).
I then opened the same video in VLC, and the background is NOT TRANSPARENT. I want to render the PNG images as an mp4, with a resulting transparent background.
I've tried many other Format/Container/Codec options as well, but cannot achieve a transparent background. Hope this is concise enough that I might get some help? The file is here:waving_flag
