🚀 What changed in this release
This update improves Subtitles/Captions mode in two big ways:
- Upload limit increased from 100MB to 150MB for captions source media.
- Auto language detection now supports a large multilingual set for caption generation.
📦 150MB upload limit (Subtitles/Captions mode)
Captions source uploads now allow files up to 150MB in Subtitles/Captions mode. This helps with higher quality source clips and fewer compression compromises.
If you still see an old 100MB message, refresh and retry with the latest build, then upload again.
🧠 Auto language detection behavior
Captions mode now auto-detects spoken language from your source media and uses that for subtitle extraction. You do not need to manually pick a language for normal usage.
Detection quality is best with clear speech, low background noise, and a single dominant language.
🌐 Supported languages (captions mode)
The following languages are currently supported for captions auto-detection and subtitle generation:
⚠️ Captions vs TTS (important)
Captions mode and TTS generation are different systems:
- Captions mode: multilingual detection and subtitle output from source media.
- TTS generation: currently English-only output voice generation.
If your workflow requires non-English subtitles, use captions mode with your original spoken audio.
✅ Best practices for reliable detection
- Prefer one dominant speaker and reduce overlapping voices.
- Trim long silent intros and outros before upload when possible.
- Use cleaner source audio over heavily processed social reposts.
- Avoid rapidly switching between multiple languages in a short segment.
