Media files | SubFT

Overview

Use the Media files page to verify every source before work moves forward

Review duration, file type, preview state, and detected metadata before starting subtitles.

Check whether the file has usable audio, existing subtitles, or alternate streams that affect the next step.

Send ready media to AI jobs, open existing tracks in the editor, or fix unsupported files first.

Readiness

Source file available
Confirm the media file is still connected before starting work that depends on it.
Audio stream detected
Speech-to-text jobs need usable audio, so resolve missing or silent streams before generating subtitles.
Subtitle streams found
Check imported sidecars and embedded subtitle streams before creating new tracks.
Language reviewed
Confirm language labels before sending media to AI jobs, editing, or export.
Next workflow selected
Decide whether the file needs generation, editing, reconnection, conversion, or export.

Decision table

If you see this	Do this
No subtitles and audio is detected	Start an AI job to generate the first subtitle track.
An existing subtitle track is available	Open the editor and review timing, text, and language.
An expected sidecar file is missing	Reconnect or replace the source or subtitle file before continuing.
The language guess is wrong	Override the language before starting AI work or export.
The file is unsupported	Convert it to a supported format first.

Next action

Use AI jobs when the file has audio or image content that needs transcription.

Open the editor when imported or generated subtitles need timing and text review.

Check file support when a source cannot be previewed, read, or sent forward reliably.
