Neon Genesis Evangelion Platinum : Telecide and Decimate

[rook2pawn]

i bought the platinum dvd's and did the whole dgindex-mpeg2source-vdub thing and thought i might share some notes about it but need some additional help

I definitely had verification that it is Top Field First (as i tried doing the AssumeBFF().SeparateFields() and saw that bottom field first gave the error like Donald Graft said in his test for field order)

i also can verify that it is definitely 3:2 pulldown (3 clean frames, followed by 2 interlaced frames).







audio = NicAC3Source("VTS_03_1 T80 3_2ch 448Kbps DELAY 0ms.ac3")
video = video = MPEG2Source("VTS_03_1.d2v").AssumeTFF().Telecide(guide=1,post=2,show=true).ShowFrameNumber().ConvertToYUY2()
AudioDub(video,audio)


Now when the video is served without any post-processing, it has 36,426 frames
The frame rate is 29.97 FPS

When I save the avi and replay, it looks great, no interlacing artifacts

Now, When i add Decimate(cycle=5)

MPEG2Source("VTS_03_1.d2v").AssumeTFF().Telecide(guide=1,post=2,show=true).Decimate(cycle=5).ShowFrameNumber().ConvertToYUY2()

The frame rate is 23.976 FPS.

STill, looks great, no interlacing.


So my question is, If Telecide alone makes it look just fine with Evangelion,
why do i have to decimate? Please help clarify my misty understanding

Because you end up with duplicate frames.

MPEG2Source("VTS_03_1.d2v")
AssumeTFF()
Telecide(guide=1,post=2,show=true) (also tried guide=2 and guide=0 , heck even guide=3)
Decimate(cycle=5)
ConvertToYUY2()

if this script has glaring errors let me know
This is used on Evangelion, and the results, while they eliminate the interlace, they.. are "less visually good" than i saw when using virtualdub's 'frame rate->inverse telecine (3:2 pulldown removal) -> Reconstruct From Fields (adaptive)

Its hard to explain the difference, but Telecide's result would create these unusual artifacts when there are many horizontal lines like when Shinji goes to MIsato's apartment, he goes "Ice, Snacks, and 50 Gallons of Beer!" well those beer have many lines drawn and then .. telecide does this line "buzzing" on those drawn lines as if the lines were pulsing a bit... But VirtualDub's 3:2 removal doesnt do this bad effect.
