- TXT + timestamped SRT
- No media upload
Support & limits
What offline transcription handles
Desktop prepares 16 kHz audio with FFmpeg, detects speech, then recognizes one segment at a time with the local model.
- Supported input
- A downloaded video containing detectable Mandarin, Cantonese, English, Japanese or Korean speech.
- Free
- Available for compatible downloaded video tasks; Free has 10 successful single-video parses per day and no profile extraction.
- Desktop Pro
- Unlimited single-video parsing and profile extraction; transcription still runs on the device.
- Profile paging
- Transcription has no paging. In a Pro profile batch, only accessible queued video tasks can be transcribed.
- Outputs
- A UTF-8 .srt file with numbered cues and HH:MM:SS,mmm timestamps; Desktop also writes a matching TXT transcript.
- Systems
- Windows 64-bit; macOS Apple Silicon and Intel. Speed depends on the local CPU and media duration.
Actual workflow
How to create local transcripts
Each step maps to a control or task state in the Desktop application shown above.
- 01
Select Extract Text & Subtitles
Enable TXT + SRT before starting a compatible video download.
- 02
Enable the local model
On first use, confirm setup and wait until Settings reports Enabled or Ready.
- 03
Let the task finish
Desktop downloads the video, prepares audio and processes transcription serially.
- 04
Open the outputs
Find the matching .txt and .srt files beside the downloaded media.
When a task stops
Common failure reasons
Failures remain attached to their task so completed items in the same queue stay available.
Subtitle timing needs editing
Desktop timestamps detected speech segments. Use a subtitle editor for reading-speed, line-break or frame-level adjustments.
Transcription is interrupted
Keep the source media in place and retry after the model returns to Ready.

FAQ
Questions about this workflow
Does SRT include timestamps?
Yes. Each detected speech segment is a numbered cue with start and end timestamps.
Can I create only SRT?
The current Extract Text & Subtitles option creates matching TXT and SRT files together.
Can I drag in any local file?
The implemented workflow is attached to compatible Desktop download tasks, not a general local-file importer.
