Intuitive avisynth editing

[Mephesto]

Oxymoron? Maybe. I'm the least qualified to say.

I have one completely processed video with several filters, but there are some parts that require a different filter [rainbowing (yes PDR, you guessed it.)]

I'm wondering what the most intuitive course of action is to fix those rainbowed parts that need some attention.

Should I process the entire video again with the extra filter and trim the parts of the first filtered video I'm keeping and the parts of the second filtered video I'm keeping, and then add all the clips up at the end?

I've found this to be tedious and annoying as I have to browse with Virtualdub and input the frame ranges on Trim which I sometimes mistype and later end up spending 20 minutes debugging after the project's finished.

I heard there was another command called "replaceframes" or something but would it really be more intuitive than trim?

Here's a rough example of what my script looks like:

a=avisource("C:\filteredvideo.avi")
b=avisource("C:\derainbowed.avi")

c=a.trim(0,1509)
d=b.trim(1510,3551)
e=a.trim(3552,3788)
f=b.trim(3789,4600)
g=a.trim(4601,5555)

...etc

c+d+e+f+g

And this takes forever.

It may not be more intuitive (both ways are very easy to use), but if you have a lot of little sections needing specific filtering it's a helluva lot easier and faster to set up, in my opinion, as opposed to typing out a bunch of trims.

# Equivalent script in ClipClop().

a=avisource("C:\filteredvideo.avi")
b=avisource("C:\derainbowed.avi")

SCMD="
1 1510,3551
1 3789,4600
"
ClipClop(a,b,scmd=SCMD)

If you use Vdubmod, it has a script editor. One feature is you can paste in the current frame using Control-P.

Or using the powerful Avisynth editor AvsP, use F11 to do the same.

And this takes forever.

Several ways to simplify that.

a=avisource("C:\filteredvideo.avi")
b=avisource("C:\derainbowed.avi")

a.trim(0,1509)    ++\
b.trim(1510,3551) ++\
a.trim(3552,3788) ++\
b.trim(3789,4600) ++\
a.trim(4601,5555)

But yes, it's a lot simpler using ReplaceFramesSimple

a=avisource("C:\filteredvideo.avi")
b=avisource("C:\derainbowed.avi")
ReplaceFramesSimple(a, b, mappings= \
"[1510 3551]
 [3789 4600]")

You have to install RemapFrames from http://avisynth.org/stickboy/ to use this.

Some versions of VDMod insert the wrong frame numbers (out by 1, in ranges, not single frames) ,
VDMod 1.5.10.3 build 2550, is OK.

CTRL P, Insert position
CTRL R, Insert Range
CTRL T, Insert Trim with Range
CTRL I, Insert Frameset As Trims

CTRL SHIFT ALT C, Comment selected lines
CTRL SHIFT ALT U, Uncomment selected lines

Most useful CTRL I, edit entire clip, CTRL I inserts all trims.
