Deinterlacing advises

[dchard]

I have an original ntsc dvd with this:

Num. of picture read: 31
Stream type: MPEG-2 MP@ML VBR
Resolution: 720*480
Aspect ratio: 4:3 Generic
Framerate: 29.97
Nom. bitrate: 9801600 Bit/Sec
VBV buffer size: 112
Constrained param. flag: No
Chroma format: 4:2:0
DCT precision: 10
Pic. structure: Frame
Field topfirst: Yes
DCT type: Field
Quantscale: Nonlinear
Scan type: Alternate
Frame type: Interlaced
Scene change detection: NOT FOUND
Variable GOP pattern: NOT FOUND
Notes:

I going to encode this with x264, but I cannot get rid of deinterlacing and pulldown (avisynth).

Can anyone help me what avisynth filter to use for this, and how?

I tried out tomsmocomp, IVTC, Tdeint. I got the best result with tomsmocomp, but whit it the output framrate was still 29,98, not 23,976.

Thank you!

have you tried just tfm().tdecimate() ? What problems does this give you?

The info given in the MPEG stream doesnt have to be *true*.
Its difficult to tell from what you've posted.
Post a small unprocessed sample (use DGIndex to select a range and save it) that shows the problem your dealing with it or alternatively post the the title of the DVD.

You should also read up interlacing and telecine.

With that I got every 5 or 6 frame look like this:

With tomsmocomp I got very nice results, but in 29,98 fps. The only question is how to decrease this to 23,976. I put tdecimate() after tomsmocomp, and I got a 23,976 video, with a sometimes skipping picture stream.

Or this 29,98 is the best I can have, and do the encode on this framrate?

Any other idea?

MOD: I uploaded a sample from the original:

Why exactly do you want to reduce the framerate to 23.976 if the video is obviously NTSC interlaced at 29.960 FPS?

The only way to do that would be blending (ugly), dropping fields (jerky) or motion interpolation (slooow) - so why not keep it at it's original frame rate?

np: Tortoise - TNT (Nobukazu Takemura Remix) (A Lazarus Taxon (Disc 2))

Yeah, you will probably want to either keep it interlaced (and bob on playback) or deinterlace and keep 29.97fps.

Ok, i will use tomsmocomp and encode with 29,98 fps.
I just realized, that this is the correct framerate, because this is not a theatrical footage.

Thank you!
