Clipped Cloud
Tired of syncing subtitles by hand? Clipped Cloud times captions to the audio for you.
Play the video, note when a line is spoken and when its subtitle shows. The difference is your offset. Subtitles late? Move them earlier.
That is a frame rate mismatch, not an offset, so one shift will not fix it all. Shift to fix the start, then fix the rest in the SRT editor.
Yes. An SRT comes back as SRT, a VTT as VTT, and so on.
No. Nothing is uploaded. The file is read and converted by your browser, on your device. It even works offline once the page has loaded.
On iPhone? Get the Clipped app, free. It cuts clips for you.
