Thanks for the effort on this topic; I suppose I will just have to use other much longer & time-consuming methods to get a perfectly-synced .mp4 file. I can always just play the video with VLC and screen-catpture with SnagIt which saves in .mp4 format. (Debut Video only saves in .avi, at least I can't find any menu item to save as any other format.) I've done that a few times, but it takes longer than being able to just rip and export to another format. Oh well. And the unlinking you suggested does work good, I'll just have to take the time and effort to do that on the relatively small percentage of discs I can't rip directly to an .iso file on the hard drive. Thank you!

Thanks for the reply; here is additional information, probably more than you need but the background info might help. I'm in the process of doing what a million others have done: turning all my DVDs and a few videotapes into digital files on a large external hard drive, and just storing the originals in the garage as backups. (My computer is connected to my large screen TV via HDMI, so I can have a choice of a hundred different movies without changing a disc or even owning a DVD player.) The software I'm using will rip ALMOST all DVDs, but occasionally has a problem, usually a disc that has lots of extras in a complicated menu structure. In that case I can just copy the individual .VOB files and process them manually with VideoPad or something else. (VLC actually does a pretty good job SOMETIMES, but not often enough for me to use it all the time.) So that is the majority of what I use VideoPad for, processing .VOB files into .mp4 or .iso. (Same problem when I just use Prism to convert the files.) I'm using VideoPad Professional 11.73, registered on 7/20/22 (upgraded from an older version). Computer is a Dell, Intel Core i7-6700 @ 3.40GHz, 16 GB ram, Windows 10 64-bit, latest updates installed Here's a public link to an example .VOB file: https://www.amazon.com/clouddrive/share/oI8bCHaNXZE5lSBavkH3gxWfoCGxsp8tOVDIyoZVvcu The file is "VTS_03_1.VOB", 459.9 MB. It's 7 minutes long and is a perfect example to show the problem. It's one of the extras from an old Gregory Peck movie, "Twelve O'Clock High", and there are many short segments throughout the clip of closeups of someone speaking. Checked .VOB file by playing in VLC Media Player, sound & picture perfectly syncronized Added file to VideoPad, was automatically placed in Sequence 1 Timeline. Played file in Sequence Preview and ALREADY there is a very slight mismatch between the audio & video! Did nothing at all with file, just immediately exported: File Format: .mp4, h264, High Quality/Larger Filesize Resolution: Auto Match Content (640 x 480) Widescreen Fit: Letterbox Frame Rate: Constant 29.97fps [TV NTSC] Subtitle: Hide subtitles Viewed the resulting .mp4 file with VLC and it has even MORE of a mismatch between audio & video which is very noticible, and just not acceptable if you try to watch a whole movie like that. I've just about resigned myself to having to get some additional software to fix the problem after exporting from VideoPad, but I'm wondering if there is something simple I'm overlooking; I can't be the only one that has this problem consistently.

I'm looking for suggestions on how to keep the audio in sync with the video. VideoPad doesn't seem to do a very good job of this (many different projects), and I'm wondering if there is some setting or menu item I'm missing when the project is exported to a video file. It doesn't seem to matter whether the original clips are .vob, .mov, .mp4, .avi, or .mkv, and it doesn't seem to matter what frame rate I choose or what format it's exported to (.mp4 or .iso are my preferred final file formats), and it doesn't seem to matter whether I choose h264 or h265 or vp8 when exporting. There's still usually at least a small mismatch between the audio and video. Sometimes it's quite noticible and very irritating, as in a closeup of someone speaking. The original source video is fine; when I preview the video (or several video clips) with VLC media player the sound is perfectly in sync with the video, but the final exported file from VideoPad is not. Can't believe I'm the only one having this problem. I know from trying to research this that audio-video sync problems are very common (not just VideoPad), and I know there are several software programs that will (allegedly) fix that problem in the final file for you, but I'd really like to avoid having to buy yet another program and take that additional extra and time-consuming step to correct something that shouldn't need correcting in the first place. Why doesn't VideoPad add this audio-video sync capability? Charge more for a "VideoPad Gold" version, fine with me, I'd buy it.
