YouTube subtitle translation FAQ
How do I export subtitles from YouTube Studio?
Open YouTube Studio, select your video, navigate to the Subtitles tab, click the three dots next to your published subtitle track, and choose Download > .srt.
Will translated subtitles stay in sync with my audio?
Yes. AI Glot treats timecodes as protected structural data. The start and end timestamps of every caption cue are kept identical down to the millisecond, preventing any audio-visual drift.
Which subtitle formats can I upload for YouTube?
AI Glot supports .srt (SubRip) and .vtt (WebVTT), the two standard caption formats recommended by YouTube and video streaming platforms.
Does translating subtitles help YouTube SEO and watch time?
Yes. YouTube indexes all uploaded subtitle tracks. International viewers searching in Spanish, Japanese, German, or Portuguese will find your video, boosting watch time and global CPM.
Why not use YouTube automatic translation or ChatGPT?
YouTube automatic captions are notoriously robotic and often introduce mistranslations. ChatGPT frequently hallucinates cues, drops millisecond precision, or breaks line splits. AI Glot preserves exact timecode syntax while translating with context-aware natural tone.
How does AI Glot handle subtitle reading speed (CPS)?
Subtitle pacing is calculated to stay within comfortable reading speeds (15 to 20 characters per second). Long dialogue lines are naturally broken into logical two-line captions rather than spilling across the frame.
Can I preserve channel catchphrases and sponsor names?
Yes. You can include channel terminology, sponsor names, and slang in your prompt instructions so brand names remain untranslated.
Can I test YouTube subtitle translation for free?
Yes. The free tool on this page lets you upload and translate your caption file (sample cues or whole files up to 25 000 tokens) with zero credit card required.
