Script

I got some problem with interlacing even though l tried to fix it.

Script:

mpeg2source("M:\My DVD Footage\Voice Of A Distant Star\VOADS.d2v")
converttoyv12(interlaced=true)
Telecide(order=1,guide=1)
Decimate(cycle=5, mode=2)
LanczosResize(720,480)
deen("a3d",3,5,5)
LimitedSharpenFaster()
Toon()

Frame by frame virtual dub:

frame5509

frame5510

Vegas:

Misc:

This was also found at the begining.

It just keeps appearing every so clip. There's a few scenes with it but l tend on using them and need them in one piece.

Any help?

in your project settings you have the field order set to lower field first, it should be set to none/progressive/whatever vegas calls it if it isn't that

oh, and your PAR should also be 0.9 (NTSC) if you're working with 720x480 footage
after decimating, your fps would be about 23.976, not 29.97

Quick question:

If l use de-interlacing method above does it always go to 23,97?

That fixed those problems but l'm still having one more.

the framerate can change depending on what filters you use (some double the framerate, you can set an arbirary rate with others) but using Telecide+decimate like that will result in 23.976 fps footage

that other pic looks like Telecide missed a combed frame, if you specify dthresh in telecide() and adjust the value (lowering it) you may be able to get rid of that

I'll go and see what l can do.

eh, you had a question so you asked.
Better yet, you got an answer

my point being, this is why the forums are here, ya know?

I tried but l don't think it was right. I looked into the guide and then didn't understand it. I don't know if this is what your talking about but l found it.

* Add show=true to telecide
* Look for a frame that is still interlaced
* a) If the info says that the frame is Progressive then you need to lower your vthresh to be lower than the "matching" number.
* b) If the info says the frame is interlaced then you need to lower your dthresh

Thats where l got until l got very confused.

It's saying the frame is progressive, so you want to lower <b>vthresh</b>; in this case, the value it's matching on is 24, so you'd want to lower it to 23 (which would hopefully make it match to the current frame instead of the next one like it's currently doing).

I do that and then the frames go back and fourth from Interlaced and progressive O.o. The problem is still there and I tried tweaking dthresh -.-.
