Pinterest video ad bitrate: no figure listed, 2 GB/15 min is 17.8 Mbps

Pinterest's video ad specs do not list a bitrate, a resolution or a frame rate. The only numeric ceiling that bears on bitrate is the file size: up to 2 GB for a video of up to 15 minutes (Pinterest page, read 2026-10-09). If you take 2 GB as 2,000,000,000 bytes and fill the full 900 seconds, the average is about 17.8 Mbps. Sume has no bitrate setting at all, so the practical check is the size of the file you get back.

What the page lists

For standard width video ads, Pinterest lists file types .MP4, .MOV or .M4V, encoding H.264 or H.265, a file size up to 2 GB, a length of 4 seconds minimum and 15 minutes maximum with 6 to 15 seconds recommended, and an aspect ratio between 1:2 and 1.91:1 (its wording) with 1:1, 2:3, 4:5 and 9:16 recommended. Nothing else is listed.

The one bitrate number you can derive

The calculation is 2,000,000,000 bytes x 8 = 16,000,000,000 bits, divided by 900 seconds, giving 17,777,778 bits per second, or 17.8 Mbps. For a 15-second ad, the recommended length, the same cap allows over a gigabit per second, so the 2 GB limit never constrains short ads. The figure only matters if you really ship a 15-minute video.

What Sume controls

Video trim takes precision (exact or keyframe), audio, and output with width, height and fps. Timeline 1.0 takes output width, height and fps. Both refuse codec, crf and similar fields with ffmpeg_fields_rejected or the timeline's provider-key refusal. So there is no way to ask for a target bitrate, and no need to when the platform does not state one.

For a Pinterest ad, a 6 to 15 second 2:3 or 9:16 clip from a timeline render will be a few megabytes at most, which is far below 2 GB. A timeline render of 15 seconds costs $0.10 (one started minute). Check the returned file size, confirm it is under the cap, and move on.

When it does matter

Only for very long videos. If you are cutting a 15-minute video, trim outputs at most 900 seconds, which is exactly Pinterest's 15-minute limit, and the timeline handles up to 1,800 seconds. A 15-minute timeline render costs 15 x $0.10 = $1.50. See the bitrate-allowance post for the Idea Ad limits and what platform specs ask for that Sume refuses.
