Avatar IV endpoint /v2/video/av4/generate always outputs video with background — no transparency support?
2 months ago by Harry
The generated video always contains a baked-in background.
We need to place the avatar video on top of another background video, but the output does not include any alpha channel or true transparency.
Even when we:
• remove the background from the source image
• attempt matting-related parameters
• try transparent or solid-color backgrounds
…the returned video still has its own background and cannot be cleanly composited.
We also noticed that enabling "matting": true results in a 500 Internal Server Error.
Is transparent / alpha video output officially supported for this endpoint?
If not, is there any recommended way to generate Avatar IV videos that can be composited over custom backgrounds?
