Problems with progressive fields from Tmpegenc conversion

Where did the video originate?
How was it processed?
What is the output format?
What TMPGenc product are you using?
How did you "rip" a home made DVD? Do you mean "copy" ?

"Rip" and "copy" mean two different things.

I no of no problem with TMPGenc and interlace/deinterlace. But PAL VHS is usually interlaced, and so is PAL DVD/MPEG2.

If you don't know what interlace-vs-progressive entails, how do you know the problem has something to do with the way TMPGenc 's field handling is the cause of the problem? Not trying to be cute, understand, but there is a major difference.

Anyway, to move VOB files from a DVD to a hard drive is just a copy procedure, but there are many ways to convert VOB to AVI. I'd use Avisynth, but there are many choices. At this point, no one would be quite certain what your playback problem really looks like. If you can cut a short 10 or 12 seconds of the output and post here, you'd get more detail answers and suggestions. Your sample should include a scene with movement.

...but I can clearly see there are like some kinds of progressive fields in the picture,

Fields are, by definition, progressive. Yes, a picture, or even better, some 10 second slice of the video, will be helpful. If the problem really is interlaced video being encoded as progressive, then ReStream can remove the progressive flag so that the player reads it as interlaced again which might (or might not) solve your problem. You'd have to demux, run the M2V through ReStream with the 'Progressive' box unchecked, reauthor, and then stick it back into the original DVD (if there are menus you want to keep, or other videos in the same DVD).

Someone else will have to explain how to encode as interlaced in TMPGEnc. But some of what you are saying is pretty screwy, so the best thing would be for you to post a video sample.

I cannot make a clip with such short notice...

Short notice? It takes less than a minute to cut a 10 second piece of the video. Open a VOB in DGIndex, use the [ and ] buttons to isolate a small section, one with steady movement, and then File->Save Project and Demux Video. Upload the resulting M2V here.

That's interlacing, yes. If your computer DVD player shows it maybe you haven't turned on its deinterlacer. Or maybe, as you say, it was really encoded as progressive. Only a video sample can help if you don't know how to figure it out yourself.

I cannot make a clip with such short notice but I post a screenshot of the videoplayback in the computer. The second picture is zoomed in to see these "lines" or what to call them.

Still images don't help much. It's not necessary to "make a clip" from scratch. If you are working with DVD, your mpeg or VOB file can be loaded into free DGMPGDec and a few seconds of video can be cut out with its DGINdex utility as a sample. They can be posted in this thread using the "Upload files/Manage attachments" button.

Standard PAL DVD is usually interlaced, NTSC is interlaced or 23.97fps progressive film with 3:2 pulldown.

That's just a calculated guess. Could be mistaken. No one could say for certain without a few seconds of the video you're working with. Try manono's idea with DGIndex to cut a sample and upload here. If you need help doing this, feel free to ask. DGIndex is free software for reading and editing VOB/MPEG and part of DGMPGDec. Available here: https://www.videohelp.com/tools/DGMPGDec

Okay. Here we go.

All the video was recorded long ago on PAL VHS tapes.
It was captured using MSI TV Anywhere TV Tuner Card (Internal) perhaps 6-7 years ago (hence the original VHS tapes are long gone). It was captured to AVI videoformat (unsure if it was raw or compressed), uncompressed Wave-sound.
I have been using TMGEnc Plus 2.5 for the conversion to DVD-MPEG-2.

Is that sample the original file ? Ripped directly from the homemade DVD ? Or was it processed in TMPGEnc (again)? Or did you mean you made these DVD's originally with TMPGEnc before ? Do you still have the AVI recordings ?

Besides being a bloody mess with noise and macroblocking , there are chroma lag issues (chroma delay "ghosting")

You can improve it with some avisynth filters . Here is a quick attempt, the basic idea is to bob-deinterlace, then chose the non duplicate frames by decimation , hopefully discarding the "bad" ones. You can make use of the fact that this is low fps (12.5) animation, by decimating to 12.5, then duplicating frames back to 25 (this way it will be cleaner, as duplicates will be "perfect")

Notes:
I used cpu=6 deblocking, there might be better deblocking , but I don't have time to fiddle with it today

Srestore does a decent job of picking the correct frames from a bob deinterlaced clip, but in this example , it chose 1 bad frame (manually replaced with remapframes) , if a few bad frames don't bother you, don't worry about it . You might get better results tweaking the settings with srestore (it might make better choices)

I didn't spend too much time with color or denoising, so of course adjust everything to your tastes. I'm sure the other folks with pitch in with some ideas as well

Cheers
