Problem

Subtitle workflows often require uploading private footage, manually matching dialogue to the timeline, or settling for captions that are difficult to edit in a professional video project.

Solution

Panto SRT runs Whisper locally, preserves the spoken-word timing, and exports SRT or FCPXML so the subtitles land in sync and remain editable in DaVinci Resolve and compatible editors.
