Weird colors when encoding

[rendicil]

I've been trying to encode a movie I have and when I open the avs file in VirtualDub and scroll through a little of it, the movie has all these weird colors and ghosts in it. What the hell is going on?

crop(0,58,720,360)
Telecide().Decimate(5)
LumaFilter(-2)
Unfilter (5,5)
UnDot()
Deen("a3d",1,3,5)
asharp(1,2)
BicubicResize(700,288,0,0.5)

Just a note - that picture is before any encoding occured. I just opened the avs file and scrolled to see the input.

The picture looks like it could normally be like that. Reflection of window panes of street lights etc, just a trick of lighting in the scene, possibly.

It's most certainly not supposed to be that way - I can provide other screenshots of characters who are naked but appear to be blue.

Could be a crop issue
Try changing the top value from the crop line to a mod4 one

Or put the Telecide/Decimate before the crop.

And get a real resolution. 700 is only Mod4.

[rendicil]

Tried doing different resolutions but they all came out bad. Tried putting telecide before crop, came out bad. Tried no cropping still came out bad. I just did a rip less than a week ago that came out beautifully but now every rip I trip I do the colors are messed up.

Edit - works now. I actually had to change it back to a mod16 to get a correct resolution.

Hi-

Ok, this is getting serious. If it wasn't the crop or resolution issue (although they were good suggestions and should be done anyway), it looks like chroma interlacing to me. But Decomb 5.2.1 has the chroma parameter set to on by default. Update your Decomb to the latest. Either that or turn on the Chroma parameter in the version you're using, if it has one. Based on your script, your Decomb is very old.

If that's not it, then perhaps it's in the source. Are you sure it's not? Have you looked at the fields? You might put on a SmartBobber such as KernelBob(Order=1) (it's part of KernelDeint), or TDeint(Mode=1), and check if you get that sort of thing in the fields. If it's in the fields, then you're pretty much screwed, I think.

And if that's not it, then maybe try a different IVTC, such as SmartDecimate, or TIVTC.

Edit: I was typing while you were editing, so I'm glad you got it figured out. So, what I wrote can serve as suggestions for any future problems with IVTC.

Thanks for the help - I dunno why the mod4 was screwing things up - I've used mod4's before without any problems so maybe next time I'll try a mod4 with those solutions.

You're using GKnot, aren't you? And if so, you changed the default W-Modul and H-Modul from their default 32 and 16? Those are the defaults for a reason. In any event, neither should ever be set below 16.
