I am attempting to convert a number of family VHS tapes to digital. I am using VirtualDub2, and so far it has worked largely without issue. Recently I've started to notice an issue where the video starts stuttering (not sure if that's the best word) during capture and it makes the resulting video file almost unusable. I was hoping to get some advice on what might be causing the problem and how to fix it.
I first noticed this issue with longer clips. It looks almost like the video capture is losing frames, but VirtualDub isn't reporting any lost frames. In the resulting file, it causes the audio to desync and the end of the video file sometimes has a freeze frame of whatever the last video frame was while the audio finishes playing. As I mentioned, this seems to be more prominent in longer clips, but it has started becoming an issue in shorter clips now as well. The strangest thing is that as soon as I stop the capture, the video feed returns to normal and it looks perfect. I think it is a software issue because of this. To reiterate, the problem is noticeable while I am capturing video and the issue is present in the resulting file, but as soon as I stop the capture, the feed in VirtualDub appears to be normal.
Has anyone experienced similar or have any suggestions on how to fix the problem?
