CutConvert

Convert a subtitle, transcript, caption, EDL, FCPXML, or Premiere .prtranscript file. Pass text file contents in `content`; pass binary files (.prtranscript) as base64 in `content_base64`. The filename extension drives format detection. Use `target` from list_converters to pick the output, or leave it as "auto" to get the default output for the detected format. Returns the converted file content (text formats inline; DOCX/ZIP as base64).

Turn an edit into projects that open in CapCut, Premiere Pro, DaVinci Resolve and Final Cut Pro, with captions and titles as each editor's own editable text. Pass a CutConvert Edit JSON document in `edit` and 1 to 4 editors in `targets`. Returns a zip as an embedded resource (application/zip): a folder for each editor and report.json, plus a short text with the warnings and the exports left. The tool sends no media. Each project points to the files at their `path` in the document; a file without a path opens offline, ready to relink. Each call is one export of the Edit API's allowance: 3 a month per network without a key, or an API key's 10 free a month and its packs when the MCP client sends "Authorization: Bearer cck_…". Edit JSON: times are seconds, positions are fractions of the frame, and unknown fields are errors. Every field: https://cutconvert.com/developers/edit-json (JSON Schema: https://cutconvert.com/developers/edit-json/schema.json). A small document: {"cutconvert":"edit/1","name":"My edit","timeline":{"fps":25,"width":1920,"height":1080},"media":[{"id":"a","name":"a.mp4","path":"/Users/sam/Movies/a.mp4","duration":30,"fps":25,"width":1920,"height":1080,"audio":{"streams":[2],"sampleRate":48000}}],"video":[{"clips":[{"media":"a","start":0,"in":2,"out":12}]}],"captions":{"items":[{"start":0.5,"end":3,"text":"Hello"}]}}

Detect the format of a subtitle/transcript/EDL/FCPXML file and report what CutConvert would produce from it, without performing the conversion or using quota.

List every conversion CutConvert supports (source format, output format, and the target id to pass to convert_file).

Parse an SMPTE timecode at a frame rate (including 29.97/59.94 drop-frame) and report its frame count and real elapsed seconds; optionally re-express it at another rate.
