Fix your video sync in under a minute. Follow these simple steps.
Choose mode according to your video issue:
Lossless Audio Offset Repair — when audio is constantly delayed or advanced throughout the video.
24FPS Timeline Repair — when video stays in sync at first but drifts gradually during playback.
Add files or drag videos into the program. A 10-second preview clip will be generated automatically. Adjust audio offset and check the sync effect before export to avoid rework.
The software recommends the best acceleration mode automatically. You may switch manually. Set your target folder; repaired files will be saved separately without overwriting originals.
Click start for single file. For multiple files, use batch queue. The program runs automatically and alerts you when finished.
Use 24FPS repair mode for TV series and streaming downloads
NVIDIA users are recommended to enable NVENC for lower CPU usage
Your custom offset settings will be saved automatically
Always keep original files safe — the tool never overwrites them
