Threads video frame rate 23 to 60 fps: conform with video-trim

Threads video must run between 23 and 60 frames per second. Sume video-trim accepts output.fps of 24, 25, 30 or 60, and every one of them sits inside the Threads range, so one trim call can conform an odd-rate source.

Which values are safe?

Only exact-precision trims can conform, because the docs state that output is exact only.

What does the call look like?

This request cuts 30 seconds and forces 1080 by 1920 at 30 fps. Do not combine output with precision: keyframe, because the API refuses that with video_trim_output_requires_exact.

curl -X POST https://api.sume.com/v1/video-trim \
  -H "Authorization: Bearer $SUME_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: threads-fps-001" \
  -d '{"video_url": "https://media.sume.com/artifacts/artf_demo/talk.mp4", "start": 0, "duration": 30, "output": {"width": 1080, "height": 1920, "fps": 30}}'

Why conform at all?

The timeline docs warn that a render whose rate differs from its sources repeats or drops frames and can judder, and report output_fps_resamples_sources. Choosing 24, 25, 30 or 60 deliberately is better than inheriting a value outside 23 to 60.

The trim price in the docs is $0.02 per job.
