Frequently Asked Questions

Can I add subtitles in a different language than the video?

Yes — this requires translation, not just transcription. Subly is the only free method that does this automatically.

What's the best format for subtitle files?

SRT is the most universal format. It works with YouTube, Vimeo, most video players, and editing software.

Do burned-in subtitles reduce video quality?

Minimally. Modern encoding preserves quality well. The advantage of burned-in subtitles is they work everywhere — no player support needed.
