How to Fix Audio Video Sync Problems

It is very frustrating when you are watching a video on your computer and the audio is out of sync. YAAI is a great software that can fix this issue with ease. YAAI shows the number of keyframes, the average bit-rate of the AVI video file as well as of the audio-stream and thus, can change the frame-rate and the audio delay.

Step

Save a backup of your video file.

Step

Download the free YAAI software by unzipping YAAI_2.0.2.485.zip file. This software only works for AVI files. If your video is in some other format, first convert it to AVI. There are several free programs that do this.

Step

Launch YAAI.exe. You will see the dialog box "Open avi."

Step

Select your AVI file.

Step

Click on the "Sync Audio" tab. You will see a video player popping up.

Step

Use the slider to adjust the audio delay or the frame rate until you are comfortable with it. Move the slider and experiment until you have achieved the right sync. This may take a few minutes.

Step

Click on "Apply." Your file should start playing with the changes you made. If you are not satisfied with the output, you can always go back to Step 6 and play with the audio delay.

Step

Close the YAAI tool. It will ask: "Do you want to keep the changes?" Click "Yes" if you are satisfied with your result.
