Common questions
How do I change the speed of subtitles?
Type the new speed of the video as a percent and click Change speed. The tool retimes every subtitle for you.
Why are my subtitles slower than the video?
If the subtitles fall further behind as the video plays, the video runs faster than the file was timed for. Enter a speed above 100, for example 104.
What speed do I enter for a 1.5x video?
Enter 150. Speed 2x is 200, and half speed is 50.
Does this change how long each subtitle stays on screen?
Only as much as the video speed changes. At 125% every subtitle is a little shorter. To set the display time yourself, use Adjust durations.
Can I slow down subtitles on Netflix with this?
No. The Netflix player controls its own subtitles. This tool retimes subtitle files that you made or downloaded.
Is my file uploaded?
No. The tool runs in your browser. Your subtitle file never leaves your computer.
