Further clarification regarding pont 2) a) above; the frame height and width of the PAL DVDs I'm working with is 768 x 576, and a lot of ripping programs seem to want to change it to a different aspect ratio when ripping it, leading to distortion.

Further to point 1) above, I meant to say that the picture is nowhere near as sharp - it looks quite blurry by comparison.

Thanks Borate

1)The file you uploaded works much better in terms of the syncing, but it's nowhere near as sharp as the original video was; and I notice the file size is a lot lower (the original file was 370MB and the one you sent me was only 242MB). Is that an inevitable consequence of reworking it at a constant frame rate?

2) Also, I assume the anomalies you refer to must have been created by the software I used to rip the DVD with - so do NCH sell a good DVD ripping program? Or could you recommend one? I don't have much money but I need one that can (a) rip PAL DVDs and maintain their original frame width and height (some I've trialed such as Filmora change the aspect ratio when ripping PAL DVDs and produce a distorted picture in the resulting MP4); and (b) if at all possible, one that can rip DVDs that don't have the same region as my laptop is set up for.

Thanks Borate, I've uploaded them in a zip file to dropbox, here.

I am trying to edit out some sections of a 50 minute documentary in Videopad (with permission from the producer), but when I open the MP4 file in Videopad, the video and audio are slightly out of sync - despite the fact that if I play the same MP4 file in any standard media player, the sound and video are in perfect sync.

I thought it might just be a problem with Videopad's preview so I tried using the method described here in order to cut out the sections that need to be deleted from the video, and I then exported the resulting project as a new MP4 file.  But in that new MP4 file the sound and video were slightly out of sync when played in any standard media player - whereas in the original MP4 file before deleting the unwanted content from it in Videopad, the sound and video are perfectly in sync.

I then tried getting the sound and video into sync by importing the new MP4 file into Videopad, and synchronizing it using the method described here. However, if I get it in sync at the start of the video, then it's out of sync at the end of the video - and vice versa.

Is there any way to get this to work with Videopad?
