Matrix Revolutions Cap & IVTC?

[ChrisBensch]

I capped Matrix Revolutions HDTV and am having a hard time deciding what to do with it. DGDecode detects it as 87.1% FILM @29.970 progressive. I looked at the output of the script below in VDubMod and it looks like 3 normal prog. frames, then two blended ones. Based on the guides, I selected 29.970 in DGDecode, but now I'm at a crossroads: to IVTC or not to IVTC? Here is my script for IVTC:

LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\DGDecode.dll")
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\TIVTC.dll")

MPEG2Source("Matrix Revolutions-HDTV-FIXED.d2v")
TFM(PP=4,d2v="Matrix Revolutions-HDTV-FIXED.d2v",flags=2)
TDecimate()

Crop(0,0,-4,-20)
Lanczos4Resize(1280,720)

The movie, whether done as 29.970fps or 23.976w/IVTC, looks fine. I guess I just don't like to process the video unless I have to. So, should I, or should I not IVTC this movie?

of course you're getting blends... it's being vertically resized. drop the resizer and check if it's got a good pattern.

interesting that it should be 87% film. it's not 20% ads is it?

i'm not sure about HDTV encoders, but SD ones with auto-IVTC option on will be VERY zealous when it comes to detecting pulldown. the repeated fields have to be practically bit-identical to be picked up as repeated fields (this is no doubt a fail-safe measure). the stream could be entirely IVTC'able, and it'll save you space and motion-jitter if you IVTC it :)

The 87% Film thing was weird to me too...it's an HDTV cap from HBO. I just don't understand it. I'm guessing it's because of the Telecine process? Who knows...all I know is that I've just begun to use the TFM/TDecimate(TIVTC.dll) stuff and I have to say the results are quite good.

I looked at the movie before resizing and it was 3 prog frames and then 2 interlaced. I just selected Force Film and all is well, I guess I need to double check the Film % that DGIndex reports.

Could post a screenshot? I just want to see what Matrix looks like in HD.
