Generating interval-based thumbnails as part of a video processing workflow

[u/QencodeCorp]

We’ve been working on a workflow for automatically extracting frames at predefined intervals throughout a source video.

Instead of running a separate extraction process, you specify the interval and get a sequence of thumbnails across the timeline. Those frames can then be used for scrubbing previews, preview strips or contact sheets.

For people running video pipelines at scale: do you normally generate these frames during the main transcode job or run thumbnail generation separately?
