how to use tweak for a fixed amount of frames?

[dede95064]

i'm having problems trying to use tweak ONLY for the last half hour of a movie i have. it's in b&w and the contrast/brightness settings for the movie towards the end are really awful.

how do i manage to tweak that last 30 min. of the movie?

for instance, if i want to tweak frames 101,232 through 115,594(end), how do i set this up using tweak?

i've tried these but with no success:

Tweak(101232,bright=-15,cont=.75) #thinking that from that frame on i needed to tweak.

SelectRangeEvery(101232,14362).Tweak(bright=-15,cont=.75).

also, where is a good place to place this in the script?

any help would be appreciated. :)

use Trim()

SelectRangeEvery : Selects a range of frames with a fixed period.

SelectRangeEvery(101232,14362) select 14362 frames each 101232 frames.

you should try www.avisynth.org -_-

and this post should be in the Avisynth Usage section.

oops. wrong forum indeed. sorry.

i tried trim but i'm not trying to trim out those frames. i'm just trying to tweak them.

i did go to avisynth.org but i didn't understand the lingo too well for using tweak when it comes to selecting some frames.

still need help.

Trim1=Trim(0,101231)
Trim2=Trim(101232,0).Tweak(Bright=-15,Cont=.75)
Trim1+Trim2

wow manono!

that's exactly what i was looking for. thank you soo much!! :D


i have to figure out how that works. what if i wanted to fix the middle of the movie only instead from 101232 to end, to something like 101,232 to 103,240---where 115,594 is the last frame??

thanks again for your help!!

manono,
you are effective.

in your "simple" 3 lines i learn more than reading tons for days.

thank you very much!

:)

what if i wanted to fix the middle of the movie...

Trim1=Trim(0,101231)
Trim2=Trim(101232,103240).Tweak(Bright=-15,Cont=.75)
Trim3=Trim(103241,0)
Trim1+Trim2+Trim3

It's not rocket science, guys. Believe me, if I can figure it out, anyone can. Isn't that so, Wilbert? :) But glad to help out.

[dede95064]

geez, manono. you've done it again! thanks a million! you're a lifesaver. :D

ApplyRange(101232,115594,"Tweak",0.0,1.0,-15,0.75)

It's a little more convenient than the trim approach.

[dede95064]

wow. that one looks like it's very advanced scripting as well. thanks neuron2! i'll try that one too. :)

[manono]

Yep, now that's rocket science. :) It may be too much for my feeble brain, but I'll give it a try. Thanks neuron2.

[jorel]

too much for you manono?

imagine for me!
i'm hypnotized.

thanks neuron2.
