How AI video tools plug into a pipeline

HeyGen: file formats

What HeyGen documents about the file formats named: one request returns an MP4. From 1 source page, read 2026-09-25; no maker pays to be listed.

authenticate, send one request, and get back an MP4

HeyGen, developer documentation: quick start

1Tools with the same reading

BytePlus ModelArk, LTX, OpenAI Sora, Synthesia and Wan (Alibaba Cloud) also document “MP4”, which makes 6 tools with this reading.

Developer documentation changes often; the live page has the final say.

2Why it matters in a pipeline

Format decides what happens next. MP4 with H.264 plays anywhere; EXR carries the range a colourist needs; an alpha channel lets a shot sit over other footage without a mask.
