Frequently asked questions
Why does it say no subtitle track?
Some files don't have embedded subtitles, or use image-based subtitles (e.g. PGS) that can't be converted to text here.
What's the difference between SRT and VTT?
SRT is common in editors and subtitle tools; VTT is great for web players and online publishing.
Can I choose which subtitle track to export?
Currently we export the first subtitle track. Track selection and language filters are on our roadmap.
Which containers are supported?
Most common MP4/MKV/WebM should work in compatibility mode, but performance depends on your browser and device.
What if extraction fails?
Inspect tracks in Metadata viewer first. For image-based subtitles, OCR is required to generate text subtitles.
