Yadif vs TIVTC

[halpern]

I have two different shows I'm trying to encode. MeGUI selected Yadif for one video and TIVTC for another during its analysis. I've noticed that Yadif (24fps) is about twice as fast as TIVTC (10-12fps). Any reason for this? Can I use Yadif in place of TIVTC? I'm getting horrible encoding fps using both in my opinion, but TIVTC is horrible.

Yadif and TIVTC serve different purposes.

Yadif is a deinterlacer and TIVTC is an inverse telecine filter.

Yadif is for use on interlaced video. Usually the frame rate will stay the same, but you can also choose to double the rate.

TIVTC is used to restore a video to 24fps after it has been telecined. Sometimes an inverse telecine filter is followed by a deinterlace filter to clean up any comb artifacts and also a decimate function to remove repeat frames.

Post the scripts being used in either case. Chances are MeGUI is using TIVTC with EEDI2 or some other EDI filter, which more often than not (in my experience) is overkill.

Here is my script generated by MeGUI for my Xvid encode. I just don't see why I'm getting such low FPS for my computer. I have an AMD X2 64 6000+ which isn't that bad.

SetMTMode(2,0)
LoadPlugin("C:\Program Files (x86)\MeGUI\tools\dgindex\DGDecode.dll")
DGDecode_mpeg2source("H:\hdtvshow.d2v", info=3)
LoadPlugin("C:\Program Files (x86)\MeGUI\tools\avisynth_plugin\ColorMatrix.dll")
ColorMatrix(hints=true, interlaced=true, threads=0)
LoadPlugin("C:\Program Files (x86)\MeGUI\tools\avisynth_plugin\TIVTC.dll")
tfm(order=1).tdecimate(hybrid=1)
crop( 0, 8, -2, 0)

Bah ha! 10 fps? You're doing pretty darn good by my books :p When you start counting the seconds per frame, then you're allowed to say that it's slow.

Honestly though, you're tfm script is rather basic and simple, no edi overkill or any other nonsensical calls besides that. Videodude did hit on a point though, just because they might give you the same or similar visual results, they are 2 completely different filters/functions.
