Frequently asked questions
What does 'burning in' subtitles mean?
It renders the subtitle text directly into the video frames, so it plays back with captions everywhere — no separate subtitle file needed, no player subtitle support required. The tradeoff: unlike a soft subtitle track, viewers can't turn burned-in captions off.
SRT or VTT — does it matter which I upload?
No, both are auto-detected.
Is it free?
Yes, free with no account required, limited to a fair-use number of videos per hour.
