Lines at the bottom when capturing VHS to DVD

[Papermouse]

Hi all,

Thanks for helping out.
We capture VHS to DVD, from a good VHS to a dvd recorder.
Once in a while, say 1 in 20 tapes or so from very different origins, we get lines like shown in the image.

Any idea what could be the cause, and how to fix or prevent it?

Thanks,

Alex

The two black lines?

Sorry, yes, the two black lines in the bottom of the screen.
They are not 100% still, but don't move around, and they are still there if I switch to another vhs-player.

Thanks,

Alex

Hm, the PAL image you posted doesn't help very much, even though you say it shows the problem. It could have several causes, but the image itself is limiting because we don't know how it was made, it's resized, has jpg compression, and some other limitations -- but the big obstacle is that it doesn't move. Readers could tell a lot more from a sample of one of your problem videos instead of a still image.

You can create a few seconds of unaltered video from the DVD source and post it in the forum. Make it with the DGIndex utility that comes with the free DGMPGDec package that you can get here: https://www.videohelp.com/tools/DGMPGDec. DGIndex can read videos directly from files like .vob, .mpg, etc. The video portion of your DVD will be on the DVD disc in file names that look like VTS_01_1.VOB, VTS_01_2.VOB, etc. You can copy such a VOB directly from a dvd disc to your hard drive.

Here's a post by a former member here that appeared a while back, shows how to use DGIndex to make and post a sample of several seconds of unprocessed video: https://forum.videohelp.com/threads/359295-Record-without-interlacing?p=2272359&viewful...=1#post2272359. Otherwise, there's not much advice anyone could offer.
