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.
Things You'll Need
- YAAI software (free download)
- Winzip (or any other zip file utility)
Save a backup of your video file.
Download the free YAAI software by unzipping YAAI_22.214.171.1245.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.
Launch YAAI.exe. You will see the dialog box "Open avi."
Select your AVI file.
Click on the "Sync Audio" tab. You will see a video player popping up.
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.
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.
Close the YAAI tool. It will ask: "Do you want to keep the changes?" Click "Yes" if you are satisfied with your result.
Tips & Warnings
- You can also change FPS (Frames per second) settings by clicking on the FPS button.
- Save a backup copy of your video file.
