Facebook Feed video ad file type: MP4, MOV or GIF from Sume?

Meta's Facebook Feed video ad page lists the file type as MP4, MOV or GIF, and Sume's Timeline 1.0, video filter and video trim endpoints each return an MP4. For a Facebook Feed upload, MP4 is therefore the format you can deliver from Sume's editing endpoints.

What does each Sume endpoint return?

The docs describe these outputs; read on 2026-09-30.

Can Sume make a GIF or MOV for Meta?

The Timeline, video filter and video trim pages describe MP4 output only. No docs page lists MOV or GIF output for these endpoints, so a GIF or MOV would come from a tool outside Sume.

What else does Meta list beyond the file type?

The same page lists H.264 compression, square pixels, fixed frame rate, progressive scan and stereo AAC audio at 128kbps or higher, plus a 4GB maximum size. On the Sume side, the video trim docs say an exact trim re-encodes with libx264 and yuv420p and remuxes kept audio as AAC, but give no bitrate. The Timeline docs do not state the codec, and none of the docs state an output file size, so check a finished file against Meta's lines instead of assuming it passes.

Video captions and sound are marked optional but recommended, which matters if you render a silent Timeline.

How do I produce the MP4?

Timeline also sets the size, so a feed render is one call. Video filter has a free check route; on Timeline use the unbilled /plan first.
