Subtitles two seconds off? Do not download another copy of the movie. One free program fixes every subtitle problem you have ever cursed at: Subtitle Edit.
It is an open source subtitle editor: shift timing, fix sync, convert formats, and even generate a subtitle file from the audio itself when no subtitle exists.
What is Subtitle Edit?
Subtitle Edit is a completely free, open source subtitle editor that has been around for years and is now at version 5. It shows your subtitle next to the video with an audio waveform, so you can see exactly where a line starts and ends.
What it does
- Sync subtitles: shift the whole file, or fix a single line.
- Convert formats: SRT, ASS, SUB and dozens more.
- Speech to text (Whisper): generate subtitles straight from the audio.
- Auto translate: translate a subtitle file via Google Translate, DeepL and others.
- OCR: turn image based Blu-ray subtitles into real text.
How to fix a delayed subtitle
- Open the subtitle file, then open the video from the Video menu.
- Play it and note the delay in seconds.
- Go to Synchronization and pick Adjust all times.
- Enter the offset, choose forward or back, and save. Done.
Why it beats the online tools
Most online subtitle tools are limited or watermark your file. Subtitle Edit runs on your machine, is fully free, and supports dozens of formats. There is also an official web version if you prefer not to install anything.

Note: Speech to text downloads a Whisper model the first time. Bigger model means better accuracy and slower processing.
Bottom line
If you watch a lot of movies and shows, keep this one on your PC. You will never hunt for another subtitle release again.
