Frequently asked questions
Which video files can it play?
Whatever your browser can play. MP4 (H.264/AAC), WebM and MP3 work everywhere; MKV or HEVC files depend on the browser. Files are played as they are, not converted.
Can I show two subtitle languages at the same time?
Yes. Add a second subtitle file as Subtitles 2. Each track has its own delay and can be hidden separately.
How do I fix subtitles that are out of sync?
Change the delay while watching: G and H move track 1 by 50 ms, J and K move track 2, and Shift makes it 0.5 s. Save as SRT writes a file with the new timing.
Is it useful for language learning?
Yes. Set a loop with A and B, slow playback down to 0.25×, jump between lines with P and N, and search the subtitle text.
Are my files uploaded?
No. Everything plays on your device. Your appearance settings are remembered in this browser only.
