Frequently asked questions
Is it really free?
Yes — generating subtitles from MP4 videos up to 5 minutes is free with no signup. For longer videos, AI summaries, and more exports, create a free account.
What is an SRT file and where does it work?
SRT is the most widely supported subtitle format — a plain-text file of numbered, timestamped captions. It works with YouTube, Premiere Pro, DaVinci Resolve, Final Cut Pro, VLC, and most social platforms. Need VTT for a web player instead? You can download that too.
Will the timestamps match my video?
Yes. The subtitle cues are generated from the word timings in your MP4's audio track, so they stay in sync when you load the SRT alongside the original video.
Can I edit the SRT after downloading?
Yes. SRT files are plain text — open one in any text editor or subtitle editor to adjust wording or timing. You can also review and copy the transcript on the page before downloading.
Is my MP4 stored anywhere?
No. Your video is sent for transcription and is not retained on our servers.
