Need Help with Gripborders()

fehmi · #1 03-16-2004, 05:55 PM

When I put the GripBorders() line in my script, the movie is centered on the screen and there are borders around the picture (I assume it is the job of this command, correct me if I am wrong). This behavior is the same on my pc and standalone (Pioneer DV-535). If i remove this line, the picture becomes fullscreen. I am using Dialhot's Optimal Avi script v4 and I would like to learn why it is used in this script if its only job is to give a centered smaller picture...

As you might see I am pretty new to KVCD and Avisynth scripts

GripBorders() makes sense as this will give the correct AspectRatio afterwards!

And FYI the borders that are arround the picture on the PC won't be seen on the TV set. That is what we call TV overscan.

If you don't want these, just put "overscan=0" in the gripcrop line.

Thanks for the feedback... But on my TV set these borders remained nevertheless

Is it possible that my TV doesnt have that feature??

In fact that is not really a feature, is more like a "default" that all TV have

. But if your one displays the borders, then do not generate them. Just modify the overscan parameter in gripcrop as said above.

Even though I put "overscan=0" in the gripcrop line, there are borders around the picture on my TV

Code:

GripCrop(528, 480, overscan=0, source_anamorphic=false) 
GripSize(resizer="LanczosResize") 
Undot() 
TemporalSoften(2,7,7,3,2) 
DCTFilter(1,1,1,1,1,1,0.5,0) 
#Blockbuster(method="noise",detail_min=1,detail_max=10,variance=0.3,seed=5623) 
GripBorders()

The original AVI has a resolution of

Code:

672x288 (2.33:1) [=7:3]

Is there anything that I am doing wrong?

BTW there are no borders around the picture the moment that the movie starts playing on my TV set. But in a second these borders appear...

Your TV display a correct image when you are watching a regular program ?

Nothing. But try with 480x480 insteed of 528. And perhaps also 544x480.

PS: you are in NTSC in Istambul ?

Yes I can watch regular TV programs as well as NTSC&PAL DVDs without any problems.

TV standard here in Turkey is PAL but my TV can display NTSC signals correctly (I can watch NTSC DVDs as I have stated above)

I will try these resolutions as well but when I choose 704x480, there arent any borders around the picture on my PC monitor : ) But I dont know if this would distort the picture
