Easy Video Sync Fixer

Easy Video Sync Fixer is a dedicated Windows application designed to permanently repair out-of-sync audio and video tracks in media files. Developed by DanDans Digital Media, it serves as a lightweight utility for users experiencing delayed sound or mismatched video streams. Key Features

Permanent Correction: Unlike standard media players (such as VLC Media Player) that only apply temporary, local playback delays, this tool modifies and exports the video file so it is permanently synchronized on any device.

Two-Way Adjustment: The tool allows users to manually delay or accelerate either the audio or the video track independently to achieve a perfect match.

Stream Stretching: It provides options to stretch the timeline of either stream, which is useful for fixing gradual audio drift where the delay gets worse over time.

Clip Preview Testing: Users can test their adjustments on a small 1-minute sample clip. This saves time by avoiding the need to render the entire movie just to check if the timing is correct.

Batch Application: Once the ideal adjustment settings are confirmed on the sample clip, you can seamlessly apply them to the full-length video file. Technical Details & Compatibility Developer: DanDans Digital Media. Latest Version: 1.3.4.

Operating System: Exclusively built for Windows (including legacy support for Windows XP, Vista, 7, and newer versions).

File Size: Very lightweight, requiring roughly 15.7 MB of storage.

License: Distributed under a Trial Version license, allowing users to test the sync tools before deciding to purchase. Popular Modern Alternatives

If you find that you need more advanced or modern features like automated wave-form matching, you may want to look into other programs:

CapCut Desktop / DaVinci Resolve: Excellent free options that can automatically align independent video and audio tracks in one click using automated waveform matching.

Filmora: Features robust auto-synchronization and audio-drift correction tools for multi-device recordings.
