Source material is 4GB .VOB from an NTSC DVD. How do I extract and save a part of it?
Here is what MediaInfo says about the VOB:
I have already tried DGIndex "Force Film", and it looks fine (also DoubleWeave().Pulldown(1,3) works), but I am wondering if it would be possible to gain some extra quality by merging fields using some HQ deinterlacer script?

Use the [ and ] selection buttons in DGIndex to mark off a section where the problem is clearly visible, set it to Honor Pulldown Flags, and then File > Save Project and Demux Video.How do I extract and save a part of it?

Just to clarify, you want only the resulting .m2v?
Ok, I understand, but is there any way to reduce motion smearing?
I was thinking of some modified HQ deniterlacer script which would work on DoubleWeave() output from AVISynth and to which I could specify which fields to combine like you do with Pulldown() (in this particular case 1, 3 works). What do you think?

The motion smearing in the clip you provided is caused by slow shutter. It's the way the movie was filmed and there's no way to remove it.
If you're talking about something else, please provide a screenshot.
Try looking at frames 450, 451, 452 in that clip. I guess it is the slow shutter as you say, but was wondering if the motion could be made more detailed by analyzing neighbouring fields just like with deinterlace.
If there is nothing that can be done to make the motion smoother and the picture sharper/more detailed then I will use Force Film.
I only can't remember for the life of me how to make audio stay in sync.
Your 23.976fps clip has 396 frames. There's no reason to be inspecting and analysing the video after pulldown.Try looking at frames 450, 451, 452 in that clip.
I think you're confused. Your video is already progressive. Any kind of motion analysis of progressive fields, which do not have a temporal dimension, is meaningless.was wondering if the motion could be made more detailed by analyzing neighbouring fields just like with deinterlace.
