Before you ask
MP4 → SRT, answered
01Is my MP4 re-encoded?＋
No. Nothing happens to your video — only its audio is listened to, and what you get back is a text file.
02Can I style the captions in the SRT?＋
SRT carries the words and the timing; the look comes from the player or platform. For captions styled the way you want them, burn them in using the editor.
03Do you hold on to my video?＋
No. Your upload is deleted as soon as the job finishes and the download expires after 24 hours.
