Sound out of sync making DVDs

I'm using Magix's new Movie Edit Pro Premium 2020. I'm running it on a ASRock X570 Taichi motherboard, with AMD Ryzen 9 3900X, and my C Drive is Samsung's V-NAND DDC 970 EVO. I actually built this computer to run the program. The videos edit great, and play back fine on the timeline all the lips sync perfectly to the soundtrack. However, when playing back a DVD made with Magix's DVD Burning program the sound syncs in the beginning and slowly goes out of sync to the point that when I get near the end I feel like I'm watching a dubbed Italian movie! How can I fix this problem?

I don't burn DVDs any more (it's easier, cheaper and better quality to send a private link from YouTube to someone) but from what I remember using another program many years ago with the same problem that it turned out to be the DVD recorder not being able to keep up and dropping frames when recording the disc at high speed. The solution then for me was to record the DVD at normal playback speed.

It may be worth trying to record at a slow write speed if that is possible within MEP to find out if the resulting DVD plays back normally. It could also possibly be caused by the file size itself. Too much information being reduced to fit. I'm not sure about the second point but either could result in dropped frames which in the past were the main causes of out of sync audio for me.

In addition to what Ray (@CubeAce) has suggested there is something else you can do which would help to prove whether the problem is linked to your DVD burner or the actual disc. Export the project to an image file. (the option is "Image Recorder" from the drop-down at the top of the Burn screen) the file extension will be .iso, and then use any "ISO Viewer" program to playback the .iso file. This page will show you how to use the iso viewer program built into Win 10 to playback your video (it should function exactly as the DVD would).

If that is able to maintain sync throughout then Ray's advice is likely to be spot-on. If it does not, please come back with full details of your computer (this post will tell you what we really need to know) as well as details of the actual source video files you are using (the free MediaInfo utility will help with this, just paste the results of the Text view here).

Thanks. I’ll try it. Hopefully it’ll solve my problem

In addition to @emmrecs comment.

What is the format of the source video you are using - use MediaInfo to analyse one of the source videos and copy the results from the Text view in MediaInfo and paste them into your post?

Audio going out of sync usually is because:

the file format is MPG (MPEG) - audio going out of sync is a common issue with this file format. To correct the problem, right click all the source video objects on the timeline and select Create frametable (new) this should fix the sync issue.

NOTE: do not use this if your video files are not MPG - it can cause more problems then it fixes.
the audio in the video file is either non standard sampling rate - Movie Edit Pro (MEP) expects a samplerate of 44.1 or 48 kHz.
the audio is variable bitrate - MEP works best with Constant bitrate audio
the video is variable frame rate - MEP works best with Constant bitrate video

For items 2 - 4 the MediaInfo analysis will give us the information.

Yes! It is MPG. I’m going to try this when I get home tonight. Hopefully this will fix the sync problem

Wow!!! The Framerate worked!

The video and audio synced perfectly. I am very happy. Thank you so much for your help! 😀
