Podcast video episode over 30 minutes: Sume's 1800-second source limit

Sume's video trim, audio detach and video inspect all refuse a source longer than 1,800 seconds, which is 30 minutes. A 45-minute podcast video has to be split into pieces under 30 minutes before the clip tools can see it. Once you have a clip, a trim costs $0.02 and a standalone caption job costs $0.20.

Limits per tool

These numbers come from the docs pages for each route. They decide how you slice a long episode.

A five-clip highlight reel

Say you pick five 45-second moments out of a 28-minute half. Five trims at $0.02 and five caption jobs at $0.20 come to $1.10, and a transcript of the 28 minutes at $0.01 per audio minute is $0.28. A trim keeps audio by default, so the clip stays usable for captions.

Limits and gotchas

• A source over 1,800 seconds fails with source_duration_exceeded at the worker.
• The transcript hint duration_seconds is capped at 600; without it Sume reserves one minute.
• precision: keyframe can start a GOP early; re-base times from actual_start_seconds.
• The clip must already be a media.sume.com artifact of your workspace; off-host URLs are refused.
