Apply Filter to Specific Frames Only

IS there a way to apply a filter to a specific range of frames? I have several filters in my script that I want to work on the entire encode, but I want one of them to filter in a specific range of frames only. Is this possible?

source=("c:\movie.avi") a=trim(source,0,100) #trim first 100 frames b=trim(source,101,0) #trim frames 101 to end a1=BicubicResize(a,640,480,0,0.5) a2=c3d(a1) done1=a2 b1=BilinearResize(b,640,480) b2=LumaFilter(b1) done2=b2 alldone=done1+done2 return alldone Thats how I do this kind of thing anyway. I find it is useful for credits when I use it with xvid's credits treatment.

If you want to use Convolution3D and UnDot on the whole thing and just ReverseFieldDominance on frames 2000-25000, it would look like this: LoadPlugin("c:\Convolution3D.dll") LoadPlugin("c:\UnDot.dll") source=("c:\movie.avi") a=Trim(source,0,1999) b=Trim(source,2000,25000) c=Trim(source,25001,0) a1=Convolution3D(a,Preset="MovieHQ") a2=UnDot(a1) done1=a2 b1=Convolution3D(b,Preset="MovieHQ") b2=UnDot(b1) b3=ReverseFieldDominance(b2) done2=b3 c1=Convolution3D(c,Preset="MovieHQ") c2=UnDot(c1) done3=c2 alldone=done1+done2+done3 return alldone There should be a faster way to do this, ie put c3d and undot in before you trim but for some reason I couldn't make it work when I was debugging it, but it should probably work.

Sorry, Acaila. I seem to have a tendency to make things way harder than they need to be. Thanks, that is much simpler.

I think I've got it. Thank you for your assistance!

I got around to trying this, and I keep getting this script error in VirtualDubMod (1.5.4.1): Invalid arguments to function "Convolution3D" Here's my script: LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\Convolution3D.dll") LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\UnDot.dll") LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\ReverseFieldDominance.dll") Source=("e:\capture.avi").Convolution3D(0,8,12,10,16,2,0).UnDot() part1=Trim(Source,0,8290) part2=Trim(Source,8291,84470).ReverseFieldDominance() part3=Trim(Source,84471,0) Return part1+part2+part3 I am using AVISynth 2.52 What am I doing wrong?

What can I say, you guys are great! Before I posted the last time, I did try putting "AVI" before each "Source," but it still wouldn't work. Then I put it just before the first "Source" and it gave me an error that "Source is not a known command." Omitting the other Sources (the ones in the trim portion of the script) seems to have done the trick. Thanks again.

Ah ha, that makes perfect sense.

Just wanted to let you know the script worked great! The encode's finally done. Thanks to everyone for the help.
