How are the SRT timestamps calculated?

Each cue lasts between 1.5 and 6 seconds based on its length at a reading speed of about 15 characters per second, with a 100 ms gap between cues, starting at 00:00:00,000.

Will the subtitles be synced to my video?

Not exactly — timing is estimated from reading speed, not from your audio. For subtitles synced to a real video, TranslateMom Studio uses AI transcription to time every cue automatically.

Is my transcript uploaded anywhere?

No. The conversion runs entirely in your browser — your text never leaves your device, and no account or signup is required.
