Help improve my script :)

[Penecho]

Here my script, perhaps some1 could look over it and say whats to improve or what is wrong :)

I mainly use it for DVB recordings (movies before 1980):

# SOURCE
mpeg2source("")

# DEINTERLACING (1)
FieldDeinterlace(blend=false)


# CROPPING
crop(12,2,696,572)

removegrain(mode=2)
msharpen(threshold=4,strength=25)
#RemoveDirt(pthreshold = 40,cthreshold = 32,mthreshold = 200)

# RESIZING
LanczosResize(512,384)

# DENOISING
fft3dgpu(sigma=0.5,bt=3,mode=1,degrid=1.0,sigma2=0.7,sigma3=1.0,sigma4=1.0)

If it's a movie you should check whether it is telecined. If so, doing IVTC will produce much better results than deinterlacing.

IVTC is only with NTSC movies or? my movie is recorded from Pal DVB :)

Even for PAL, you may have just a one-field phase shift. Try using Telecide() by itself (no Decimate). Or you can post a small unprocessed source sample.

I uploaded a sample here:

That's progressive. Why do you want to deinterlace it?

[Penecho]

I thought it was interlaced coz usually the TV broadcasts are in 576i, had that on some shows. this vid lookd a bit weird so i thought better to deinterlace.

Are there any other filters who could improve the quality of this vid?

Don't get the disease called filteritis, the video equivalent of being a hypochondriac. Is there a problem in the video that you need to correct?

[Penecho]

When i encode it it looks, like there is a small amount of blocking!? but i also make it bigger when i watch it to fit it to my desktop res. (1920x1200)

And has the deinterlace any negativ effekt on a video that is already progressive?

Yes, deinterlacing can degrade a progressive movie if the deinterlacer decided some pixels are combed that aren't really. Besides, it wastes a lot of time.

Before you look at filtering, figure out if it's your encoding causing problems. If you're trying to encode it way too small, then you should either raise the size (also see xvid presets thread in xvid forum), use a better codec (like AVC or WMV9 AP), or add some filtering to make it compress better, like fft3dfilter. But don't filter just because. You'll butcher quality if you just apply random filters and encode with basic settings.

512x384 is going to look quite blocky on a 1920x1200 screen no matter what you do. Is there any reason why you can't leave it at full PAL resolution and put the bitrate up accordingly, or are there space limitations (burning to CD or whatever)?

The source is quite good - it is only a bit grainy, so as others said there's no need to go overboard with filters.
