Frequently Asked Questions - SRT Subtitle Generation
What input formats can I use to generate SRT files?
We accept all major audio formats (MP3, WAV, M4A, FLAC, OGG, AAC, WMA) and video formats (MP4, AVI, MOV, MKV, WebM). Upload your file directly - no conversion needed.
How accurate are the SRT timestamps?
Timestamps use millisecond precision (e.g. 00:01:23,456) and are aligned to the actual speech start and end times. For clear recordings, caption timing is typically accurate to within 50–100ms, requiring minimal manual adjustment.
Can SRT files include speaker labels?
Yes. Enable speaker diarization and each caption block is prefixed with the speaker label (e.g. [Speaker 1]: ...). This is especially useful for interviews, podcasts, and panel discussions.
What subtitle formats do you output?
The primary output is SRT. You can also download VTT (WebVTT) and plain text simultaneously from the same upload.
Is there a file size limit?
For larger files, contact us for batch or enterprise options. The maximum file size depends on your plan.
Can I translate the SRT file after generating it?
Yes. Check language support before submitting your file.
