deinterlace originally film footage.
-
did you try renaming it to .mpg?
that’s really odd. Jim Simon’s helpful program XviD4PSP works with a lot of people. did you select uncompressed avi and wave?
i used to use a program called vob to avi. its still free i see. if you choose some compressed codec, you’d had to get the same plugin support for your editor. that’s why uncompressed avi is recommended, plus there’s no quality loss.
short of sending a vob example to us, I don’t know what to tell you except try another vob to avi converter with uncompressed or codec support. you can check the codec with mediainfo in tree view.

i cant even get the program to simply play a preview of the vob file in the program. I also tried moving the file off the disk and renaming it to .mpg .
windows media will play the disk just fine so I know its at least working

looks encrypted to me.

If you drop this interlaced footage in a interlaced sequence with upper field and the display mode to first field and you are seeing interlaced artifacts I am guessing the file is not as it should be. Fields have been messed about.
BTW i cannot get Jims program to work properly either.———————————————–

I was able to rip the vob file using a program called “dvd fab” however…
it will either copy the file without doing any sort of deinterlacing which means its a 29,97 fps file with the 3:2 pulldown intact. Or , it will do it’s own terrible deinterlacing and give the file a “frame blended” effect.
when I have the non deinterlaced file with the 3:2 pulldown intact , the 3:2 pulldown changes sequence every time the scene cuts or changes. I CAN fix this in adobe and somehow get it back to normal 23.97fps however , the quality takes a dive and gives the video a “no anti aliasing” effect.

if you place the 29.97i into after effects and into a 59.94 comp, each field will become its own frame, then simply
download the duplicate frame removal script and it should remove the duplicate frames, thus deleting the embedded duplicate fields. render that out as new 23.976 comp no fields. should not matter if the cadence changes.https://aescripts.com/duplicate-frame-remover/

Alright I’ve almost given up on this
The problem appears to be that ripping the dvd footage yields a non deinterlaced 29.97p file. I’ve now tried SIX different free ripping programs. All of which rip the same type of file. ALL of these programs have deinterlacing options which only yeild a frame blended 29.97p file which of course looks terrible.
The only thing I’ve found that can have any effect on the 29.97p semi interlaced file is premiere which simply remove an entire field resulting in massive quality loss.
I still don’t understand how the dvd can play perfectly fine , yet not be ripped perfectly fine. How the dvd playing program can easily figure out that the show is 24fps and play it in perfect quality , but every ripping program cannot figure that out.
what a headache

VirtualDub does support MPEG-2 though not with just the stock program. FccHandler’s plugins are an absolute must-have for anyone using VDub. You specifically need the FccHandler MPEG-2 plugin and when you File – Open Video File and select the first VOB file, you need to also check “Ask for extended options after this dialog” underneath the file browser. One of the extended options for the MPEG-2 handler is to open multiple VOB files as a single file; check that and it’ll try to auto-pick the successive VOBs for you, but you can edit the list before opening.
Once you’re in VirtualDub, you’ll need to set the video menu to “full processing mode” and you’ll need to use two filters: IVTC (inverse telecine) followed by Deinterlace. IVTC will give you options for field order and field assembly; it sounds like you want to “reduce frame rate” in that dialog and leave the others alone unless the field ordering is incorrectly detected by Autodetect. If you want to preserve the 24p frame rate, the Deinterlace filter options you want are “Blend fields” and “Keep X field, interpolate/discard Y field” (depending on the field order; try “Keep top field” first, change if that doesn’t work right).
You’ll also need to pick a codec under Video – Compression or you’ll get an uncompressed RGB export. I’ve been using UtVideo for intermediate lossless encoding and that may work for you; other options include Lagarith or the FFV1 compressor provided by ffdshow, but I’ve had issues with those options before so I think UtVideo Rec.601 4:2:0 is what you’d be best exporting to from VDub.

no, your original assumption is incorrect. your video should look like this in mediainfo if its really 23.976.
Display aspect ratio : 16:9
Frame rate : 23.976 fps <——-
Standard : NTSC
Color space : YUV
Chroma subsampling : 4:2:0
Bit depth : 8 bits
Scan type : Progressive
Scan order : 2:3 Pulldown <——-see the difference?
that’s because of mpeg2 flags; you can have all sorts of mpeg2 DVD stuff. some is 23.976 with 3:2 pulldown flags, others are 29.97i regular alternating interlaced frames, others if you had a 29.97p, it would be converted into 29.97i with progressive interlaced frames each frame 2 fields complete image.
you probably have a 29.97i with fields permanently burned in, no flags whatsoever!!!
that’s why you need to analyze the fields and write down frame by frame to see fields and complete frames ie. WWSSW in after effects.
what troubleshooting steps have you done in premiere, after effects? tried placing it in 23.976 sequence in premiere, interpret lower/upper? a 59.94 comp in AE? deleted duplicates frames with AE script or ffmpeg?if, for some reason, there is no pulldown burned in, you have a doubly messed up video stream and might just need to deinterlace with qtgmc.

Jody,
that’s helpful instructions. virtualdub seems like it has a good chance of doing everything in one pass. the newer virtualdub has an adaptive pattern phase ivtc filter (set field assembly mode, reduce framerate. pretty amazing its all free.
