Different filtering on different parts

[tormento]

I have an anime, with a very noisy part in the beginning (i.e. credits) and then it's all digital art (noiseless).

Is it possible to use AVS+ to apply different (or no) filters to different parts or have I to use different .avs files, each with its own range?

Sure you can. Here's a script that denoises the first 250 frames only of your lighthouse clip.

src=dgsource("The lighthouse.dgi")
vid1=src.trim(0,249).dgdenoise()
vid2=src.trim(250,576)
vid1++vid2

SHOW=True

ClipClop(ORG,V1,V2,V3,V4,V5,V6,V7,V8,V9,V10,V11,V12,scmd=SCMD,nickname=NickNames,show=SHOW)

Supports up to 255 replacement [edited/denoised or whatever] clips.

EDIT: If only 2 sections, then as VideoH said is probably easier, use ClipClop where many edits as trim/splice quickly gets awkward.

Or directly:

ApplyRange(start_frame, end_frame, "Your Denoiser", arguments for your Denoiser)

Videoh's suggestion is more academic and TinMan's suggestion is for more complex cases.

MeGUI's AVS Cutter can be useful for that sort of thing. It opens a script with a preview, so you can navigate through the video while specifying the start and end frames for each trim (very much like specifying start and end editing points with VirtualDub). It can be handy if you need to divide the video up into many parts, and obviously you have to find each sections start and end frame number anyway, so you can add the trims while you're at it.

I had a dream that one day the AVSCutter would include the ability to specify the filtering to be used with each trim, but I doubt it'll ever happen. They look like this. It's easy enough to tack-on the appropriate filtering once they're saved to the script.

__film = last
__t0 = __film.trim(0, 2840)
__t1 = __film.trim(2841, 6451)
__t2 = __film.trim(6452, 11024)
__t3 = __film.trim(11025, 16271)
__t0 ++ __t1 ++ __t2 ++ __t3

With AvsPmod it is also possible with preview.
Various options are also offered, and the selection can be saved in the script for later editing.

c0 = Trim(522, 801)
c1 = Trim(1053, 1236)
c2 = Trim(1454, 1733)
c3 = Trim(1959, 2203)
c4 = Trim(2464, 2647)
c0 ++ c1 ++ c2 ++ c3 ++ c4

Thanks everybody!

When your problem is a nail, any hammer will do.

Or a reasonably heavy screwdriver can work also.

For sure. OJ and vodka lubricates all tasks!
