"Hello! i am attempting to make a collection of a web-series to burn on BD through multiAVCHD, but every time i export the finished project the audio is very slightly out of wack. is there anything i can do to fix this?"

"I've been burning some of my movies to blu and, for some reason, I'm having sync issues with MultiAVChd. It's not a major difference but enough for it to look weird. Everything I'm recording is through the Hauppauge. I use Videoredo to edit. Then I put it into the program and it's not being reincoded. However, for some reason, whenever I play it back, I'm getting problems with the HD stuff being just slightly out of sync. Nothing different with the regular mpeg-2 stuff. Any ideas?"

If you've tried creating Blu-ray collections using multiAVCHD and encountered slightly off-sync audio, you're not alone. Audio and video synchronization issues with multiAVCHD can be frustrating but are also fairly common. Users have reported slight mismatches between audio and video timing, often after editing in other software like Videoredo or capturing content with devices such as the Hauppauge. The good news is that there are several ways to address this problem to produce smooth, synchronized Blu-ray content.

Part 1. How to Fix Audio Sync Issues with multiAVCHD

MultiAVCHD is a versatile tool for creating Blu-ray compilations, but it can sometimes introduce slight timing errors. Here are two primary methods to adjust the settings and improve audio and video sync:

Method 1: Match Frame Rate Settings

One of the most common causes of sync issues is a mismatch between the original video's frame rate and multiAVCHD's settings. Here's how you can adjust the frame rate in multiAVCHD:

• Open multiAVCHD: Start the application and load the project or video file where you're experiencing sync issues.
• Find the Author Tag: Once the video is loaded, navigate to the "Author" tag in the settings panel.
• Go to the TV System settings: Under General, locate the TV System option, where you’ll find three choices—PAL (25 fps), PAL24 (24 fps), and NTSC (29.97 fps). Use a tool like MediaInfo to check the original video’s frame rate and ensure it matches the setting in multiAVCHD. For instance, select PAL24 for a 24 fps video.

Method 2: Adjust Audio Delay

If the audio still seems slightly out of sync, adjusting the audio delay can help align the audio and video tracks more precisely. Here’s how to set a custom delay in multiAVCHD:

• Open multiAVCHD: Start the software and load your project with the desynchronized video.
• Select the Unsynchronized Video: Click on the video file where the audio is off-sync to highlight it.
• Access Properties: With the video selected, click the “Properties” button. This opens a settings window where you can adjust specific properties of the video file.

• Go to the Audio Tab: Within the Properties window, navigate to the “Audio” tab. Here, you’ll find an option labeled “Delay.”
• Set the Delay: The delay setting allows you to specify an offset time in milliseconds. If the audio plays ahead of the video, enter a negative delay (e.g., -1000 ms for a 1-second delay). If the audio is lagging, enter a positive delay (e.g., 1000 ms for a 1-second advance).
• Save Changes: After setting the delay, click “Change” to apply it. Test the playback to see if this adjustment resolves the sync issue.

Tips for Minimizing Sync Issues in multiAVCHD Projects

In addition to the above methods, here are a few tips to help you avoid or reduce sync issues when using multiAVCHD:

• Pre-Process Your Videos Consistently: Before importing files into multiAVCHD, ensure that your editing or recording software (such as Videoredo or Hauppauge) maintains consistent frame rates and audio settings. This can minimize the need for additional adjustments later.
• Avoid Excessive Re-encoding: When possible, avoid re-encoding your video files multiple times, as each pass can introduce slight timing differences. If your source files are in a compatible format, import them directly into multiAVCHD without re-encoding.
• Test Settings on Short Clips: For large projects, test your settings on a shorter video clip to verify sync before processing the entire compilation.
