Upload a video and try remuxing, timestamp rebuild, full re-encoding, damaged-frame skipping, metadata repair or stream extraction. The result is saved as a new MP4 file.
✓Fast remux keeps streams when possible and is usually the quickest option.
✓Full re-encoding is slower but can fix more playback issues.
✓Ignore-errors mode can salvage files with damaged frames.
✓Metadata repair is useful for MP4 files that start slowly or fail seeking.
✓If only audio is broken, try repairing the audio track or saving video without audio.
✓Severely truncated files may require a matching reference video and cannot always be repaired automatically.
