Avisynth: Video Opens Slowly?

kvcdexplorer · #1 06-27-2005, 09:08 PM

I am currently trying out this script:

Code:

AviSource:
BlindPP(cpu=4) 
Blockbuster(method="noise",detail_min=1,detail_max=3,variance=0.1,seed=1) 
Convolution3D(1, 6, 12, 6, 8, 2.8, 0) 
GripCrop(height, widht, overscan=1, 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()

It works good but when i try to open its so slooooowww. to open and play the file.

Anyone know why its causing this, suggestions,answers,questions feel free to reply thanks.

What is slow

Playing the script, or the encoded MPEG file

This happens everytime when i try using the script, for example when i try using it in windows media,virtualdub,tmpgence etc.

And that is normal, because you can't play a video using all these filters, and expect real time playback

( Unless you have a VERY fast 3GB+ machine!, and also depends of what filters you choose )

ha Just what i suspected but. is there anything i can do, or remove some of those filters and still get a good image??

because seriously it takes over quite a long time to open sir.

Thanx alot kwag sir

Have you the slighest idea about "using filter" means ?

As Karl tried to explain you, you can't expect to have a good looking filtered picture AND have a realtime playback speed. And of course the encoding time is also affected.

Nevertheless FYI, the opening time is longer because gripfit is computing the resize parameters. If you use fixed resize values (lanczosresize + addborders vor instance) the opening time will be a lot shorter.
