Which transparent format should I use?

WebM (VP9 alpha) is the go-to for websites in Chrome, Firefox and Edge. Safari needs HEVC with alpha in an MP4, which Rewwwrap creates with its optional native helper.

GIF supports only on/off transparency but works everywhere images do. ProRes 4444 MOV is the lossless-quality choice for moving transparent footage between editing apps.

Frequently asked questions

How do I know if my video has transparency?

Rewwwrap detects alpha automatically. ProRes 4444, Animation (QTRLE), PNG-in-MOV, alpha WebM and transparent GIFs all qualify.

How do I show transparent video in every browser?

Offer an HEVC-alpha MP4 source first (for Safari) and a VP9 WebM second (for everyone else) in the same video tag.

Why does my transparent video show a black background?

The player does not support alpha — QuickTime ignores WebM alpha, for example. Test in Chrome for WebM and Safari for HEVC.
