Common Questions
Short answers to the export problems that usually show up as a black background.
Playback
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.
Read the guide →FormatCan 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.
Read the guide →SafariWhy is my transparent WebM black in Safari?
Safari ignores WebM alpha. Chrome and Firefox composite it. Safari needs HEVC-with-alpha.
Read the guide →FormatWhat video formats support a transparent background?
WebM transparent background (VP9 yuva420p), ProRes 4444, HEVC-with-alpha. Everyday H.264 MP4 does not.
Read the guide →FormatHow 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.
Read the guide →ExportWebM transparent background — alpha channel export
Export VP9 WebM with yuva420p (fog/overlay-friendly), or encode locally with FFmpeg if you already have alpha.
Read the guide →BasicsWhat is a video alpha channel?
The fourth channel that stores per-pixel transparency. Without it, transparent regions become black.
Read the guide →QualityWhy does AI video background removal flicker?
Frame-by-frame masks drift. Temporal video models keep edges stable across time.
Read the guide →OBSCan 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.
Read the guide →ExportHow do I export a transparent video from After Effects?
Render QuickTime ProRes 4444 with RGB+Alpha. Then edit the MOV, or convert it to WebM. AE does not natively export WebM alpha.
Read the guide →ExportHow do I export a transparent video from Premiere Pro?
Use QuickTime ProRes 4444 with alpha. Everyday H.264 MP4 will not keep transparency.
Read the guide →OBSHow 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.
Read the guide →ExportHow 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.
Read the guide →AlternativeWhat is an Unscreen alternative for true-alpha video?
Unscreen's standalone service has closed. ExportAlpha removes the background, then writes real WebM or ProRes alpha.
