Cannot deinterlace in Video Mastering works (tmpgenc)

[geneariani]

I am trying to remove interlace line artifacts that occurs during fast motion in animation mpeg file. I use Video Mastering works (formerly Tmpgenc) and have tried following settings:

Video Original frame rate: 23.976fps interlaced
Video Mastering Works Deinterlace Filter Settings:
Deinterlace mode: Deinterlace Always (double the Frame)
Deinterlace method: inverse pull-down(reinforce anti-stripe)
Output file format:
Mp4 AVC - 59.94 fps Constant bit rate

However as can be seen in the attached image when there is fast motion the lines become visible.

I hope I am on the right track and these are interlacing issue.

Post a sample of your source.

I have attached a sample of the original video file sample.

That's pretty much straight 3:2 pulldown. The Inverse Pulldown method should work and give you 23.976 fps progressive frames. I seen to recall that function didn't work very well in the older version of TMPGEnc. And the video does have a problem where the chroma channels were mishandled so you will sometimes get a big of blended colors:



Attached is an MKV file with x264 video from an AviSynth inverse telecine script (TFM().TDecimate()).

Thank you very much for taking the time to work on this. I looked at your sample and there were no of the artifacts which I encountered. I am going to use telecine script and import it in Video Mastering works.

Thanks again

If you're going to use AviSynth I suggest you use DgIndex to build an index file (.d2v) of your source video, then Mpeg2Source() in the AviSynth script. You might as well activate the deblocking and deringing filters too:

Mpeg2Source("filename.d2v", CPU=6) # deblock and dering
TFM()
TDecimate()

You'll have to download and install the TIVTC package for AviSynth if you don't have it already.

You might also consider some noise reduction, etc.

Thanks for d2v suggestion. Going to have fun scripting on Christmas day
