Fix Audio Sync Issues with XMedia Recode It is frustrating when a movie or video clip has audio that does not match the video. If people’s lips move but the sound comes a second later, you are dealing with an audio sync issue. XMedia Recode is a free, powerful video converter for Windows that can permanently repair this problem.
This guide explains how to use XMedia Recode to align your audio and video perfectly. Why Audio Sync Issues Happen
Audio and video are stored as separate tracks inside a single file container (like MP4 or MKV). If a variable frame rate is used, or if the media player misreads the file headers, these tracks can drift apart. XMedia Recode fixes this by adding or subtracting time from the audio track to match the video. Step-by-Step Guide to Fixing the Sync Step 1: Import Your Video File Open XMedia Recode. Click the Open File button on the top toolbar. Select the video with the sync issue and click Open.
Click on the video file name in the main list to highlight it. Step 2: Configure the Video Track (Avoid Re-encoding)
You do not need to waste time re-encoding the video track. You can copy it directly to save time and maintain original quality. Click on the Video tab in the lower half of the window. Look for the Mode dropdown menu. Change the mode from Convert to Direct Stream Copy. Step 3: Configure the Audio Track Click on the Audio track 1 tab.
Ensure the Mode here is also set to Direct Stream Copy if you want to keep the original audio format.
Note: If you need to change the audio format for compatibility, leave it on “Convert” and select your new codec. Step 4: Apply the Audio Delay This is the most critical step to fix the timing.
Look for the Audio Delay (ms) field at the bottom of the Audio tab.
Enter the sync correction value in milliseconds (1 second = 1000 milliseconds).
If the audio plays too early: Enter a positive number (e.g., 500 for a half-second delay).
If the audio plays too late: Enter a negative number (e.g., -500 to shift the audio forward by a half-second). Step 5: Save and Render the File
Go to the bottom of the window and click Browse next to the Output folder to choose where to save your fixed video. Click the Add Job button on the top toolbar.
Click the Encode button (next to Add Job) to start the process.
Because you selected Direct Stream Copy, the process will finish in just a few seconds or minutes, depending on the file size. How to Find the Exact Delay Amount
If you do not know the exact millisecond offset, you can find it using a free media player like VLC: Open the broken video file in VLC Media Player.
Use the J key (shifts audio backward) or K key (shifts audio forward) on your keyboard while the video plays.
Watch the on-screen notification in VLC, which displays the offset in milliseconds (e.g., Audio delay 300 ms). Take that exact number and type it into XMedia Recode. To help you get the best results, tell me:
Do you know the exact time difference between the sound and video? What file format (MP4, MKV, AVI) are you working with?
Does the audio drift worse over time, or is it off by the same amount from start to finish? I can provide specific settings based on your answers.
