Video format and playback
What video formats support a transparent background?
WebM transparent background (VP9 yuva420p), ProRes 4444, HEVC-with-alpha. Everyday H.264 MP4 does not.
Why does my transparent video have a black background?
Often black was built into an MP4, or the player ignores alpha. Format and playback—not a recoverable fill.
Can I export MP4 with alpha?
Everyday H.264 MP4 has no true alpha—including files with black built in. Use WebM or ProRes 4444 instead.
Why is my transparent WebM black in Safari?
Safari ignores WebM alpha. Chrome and Firefox composite it. Safari needs HEVC-with-alpha.
WebM transparent background — alpha channel export
Export VP9 WebM with yuva420p (fog/overlay-friendly), or encode locally with FFmpeg if you already have alpha.
How do I compress a video with an alpha channel?
Keep alpha while choosing a smaller delivery file. Compressing an opaque MP4 does not create transparency.
What is a video alpha channel?
The fourth channel that stores per-pixel transparency. Without it, transparent regions become black.
Why does AI video background removal flicker?
Frame-by-frame masks drift. Temporal video models keep edges stable across time.
Editors and OBS
How do I export a transparent video from After Effects?
Render QuickTime ProRes 4444 with RGB+Alpha, or import an ExportAlpha MOV and interpret Alpha. Everyday players often keep leftover green.
How do I export a transparent video from Premiere Pro?
Use QuickTime ProRes 4444 with alpha. Everyday H.264 MP4 will not keep transparency.
Can I use a transparent video overlay in OBS?
Yes. Media Source with transparent WebM, or Browser Source for a hosted page. Do not chroma-key it.
How do I use a transparent WebM as an OBS Stinger transition?
Attach VP9 WebM with alpha in Scene Transitions. This is a scene-change stinger, not a Media Source overlay.
How do I convert a ProRes MOV with alpha to WebM in FFmpeg?
Encode existing ProRes alpha to VP9 yuva420p. FFmpeg cannot invent a matte from an opaque file.
