Question 1

What video formats does Hypervideo support?

Accepted Answer

Input: MP4, WebM, MOV, AVI. Output: WebM (VP9 alpha), APNG, Stacked-Alpha MP4 (H.264), WebP sequence, or ProRes 4444 for Safari.

Question 2

How does stacked-alpha work?

Accepted Answer

We split the alpha channel and stack it below the RGB frames in a single H.264 video. Our players use WebGL (web) or Metal (iOS) shaders to composite them in real-time.

Question 3

Does Hypervideo support green screen removal?

Accepted Answer

Yes! You can specify a manual chroma key color, or let our AI auto-detect the background color from the video edges.
