Frame extraction is fast — typically 20-30% of source duration on the standard pipeline. A 5-minute MOV → TIFF bundle finishes in about a minute regardless of frame count, because the bottleneck is the TIFF encoder, not the demuxer.

Yes — the advanced option accepts a comma-separated list of timestamps (e.g. `00:01:23,00:05:00,00:10:42`) and produces one TIFF file per timestamp. Useful for chapter thumbnails, scene reference shots, or generating poster frames for HTML5 video.
