Supported files
The audio, video, subtitle, and transcript formats Bristlenose reads.
Bristlenose reads a folder of files and works out which belong together. You can mix audio, video, subtitles, and transcripts in the same folder.

How files become sessions
Files that share a name stem are treated as one session. For example, p1.mp4 and p1.srt are the same session — Bristlenose uses the video for playback and the subtitle for the transcript.
When a session already has a subtitle or transcript, transcription is skipped for it. This is faster and uses no transcription model.
Platform-specific filename suffixes from Zoom, Teams, and Google Meet are stripped before stems are compared, so files exported by those tools group correctly without renaming.
.txt transcripts are read by the bristlenose analyze command, which works from existing transcript files. They are not picked up by run or transcribe, which scan for media and the formats listed above.
