NTSCfilm/NTSC hyrbrid to NTSC framerate...

[iThinkYouBrokeIt]

I have several source files which are MPEG-2, from dvd.
It seems like the framerate is 23.976/29.97 mixed.
I need to convert to 29.97 for conversion to MP4.

What I'm trying to do is first convert it to avi so that I can apply filters such as brightness, de-interlacing, and audio normalizing before converting to MP4.

I'm using DGIndex and TMPGEnc for the process of converting to avi, and PSP Video 9 to convert to MP4.

The problem is during the TMPGEnc stage, I see that it suffers massive interlacing errors due the variance in framerate. The timing of the video (audio sync) is not affected, but the interlacing errors are terrible. It seems as though the coloring of the fields are interfering with each other and it won't de-interlace properly. It looks like it has something to do with the fact that the source is 24fps and is then converted to 30fps (interlacing) then de-interlaced.
left - orginal, right - deinterlaced (duplicate field 1)


Is there a program that can take the VOB with the varied framerate and "standardize" it to 29.97fps for me? Maybe by duplicating frames instead of interlacing?

I've tried changing the settings in DGIndex. It seems alright mostly when i set DGIndex to use film framerate. But then theres the scenes that are 30fps, which will suffer under that setting. And the end result file will have 30fps...

try the guides to do with decimate

When using DGIndex you want FIELD OPERATION set to HONOR PULLDOWN FLAGS and this will give you 29.970fps from start to finish which is what you want.

Sounds like maybe you are setting it to the FORCE FILM option which is incorrect for HYBRID material such as what you have.

Yeah, it has to be Honor Pulldown Flags to get it to 29.97fps. Although I think you can then deinterlace off of one field or the other in TMPGEnc, it'll deinterlace everything, lowering the quality of the frames that don't need deinterlacing, and cutting the effective resolution in half. Much better will be AviSynth's TDeint(Full=False). It'll leave the already progressive frames alone, and deinterlace off of a field, but give full resolution to static areas of the frames being deinterlaced. When done you'll have a nice 29.97fps video, with dupe frames (and therefore playing slightly jerky) on the 23.976fps parts.

Make sure you deinterlace before cropping and/or resizing.

Frameserving an AviSynth script into VDubMod set for Fast Recompress, and doing all the filtering in AviSynth will allow you to encode much faster with better quality.
