Amazon video ad frame rate: set Sume Timeline fps to 24, 25 or 30

For an Amazon Sponsored Brands video, set Timeline output.fps to 24, 25 or 30, matching the frame rate your source was shot at. Amazon's spec lists 23.976, 23.98, 24, 25, 29.97, 29.98 and 30 fps. Sume's Timeline accepts only 24, 25, 30 and 60, so the exact 23.976 and 29.97 options cannot be selected and the closest allowed values are 24 and 30.

Why the setting matters

If you omit output.fps, Timeline renders at the rate of the sources, with the longest video sources deciding. If you set a rate that differs from a source, the docs say the job repeats or drops a frame every few frames, which causes judder on motion, and it reports output_fps_resamples_sources with the rate the sources wanted.

Steps

• Run video_inspect with frames: false on the source to read the probe. It is the cheapest way to see what you are working with.
• If the source is near 24 fps, set 24. If it is near 30, set 30.
• Run the unbilled plan call, then render.
• Read warnings[] in the result. A resample warning means the source rate was different from what you set.

Sources that mix 24 and 30 fps clips in one timeline will always resample some of them. Group shots by rate when you can.

A short decision rule

Use the source rate when you can. If every clip in the timeline was shot or generated at 24 fps, set 24. If your phone footage is 30 fps and nothing else is mixed in, set 30. Both are on Amazon's list. If you mix, pick the rate of the majority of the screen time and accept that the others will be resampled.

The docs describe the resample as repeating or dropping a frame every few frames, and say the job reports output_fps_resamples_sources with the rate the sources wanted. That warning is information, not an error: the render still finishes. Treat it as a prompt to watch the motion-heavy parts.

Amazon's page also lists a minimum video bit rate of 1 Mbps with 4 Mbps recommended, and a minimum audio bit rate of 96 kbps with a minimum sample rate of 44.1 kHz. Sume's docs I read do not state the output bit rates for Timeline, so measure the delivered file with a media tool before you upload.

What Sume does not do

Sume does not offer fractional rates like 23.976 or 29.97 in Timeline output, and I could not find a pass-through setting. It also does not verify the bitrate floor Amazon lists (1 Mbps minimum, 4 Mbps recommended). Check that on the delivered file.
