Range() v3.2 Now with rg()

The if/then statements were necessary for avoiding issues when using trim() in certain situations. (though it looks like you've made some changes to address trim's issues in your script now so you probably know that...) But yeah, it could have been written better.

lol, I guess I put my foot in my own mouth.
It actually required more if/then statements than you used to cover the really annoying special cases like:
sceneadjust(0,all-1, "invert()") # see what happens to the last frame
sceneadjust(0,0, "invert()") # splits the video in two
sceneadjust(1,all, "invert()") # misses the first frame

The special cases were such a pain, and I wouldn't be surprised if I missed any,
so I take that back. :beer:

Minor update:
Code: Select all
CHANGELOG:
v3.2 - Included rg() function with conveniently rearranged variables: rg( head,startframe,endframe,tail,mod )

Generally range() is used by specifying the startframe, endframe, modification, and some generic fadein/fadeout frames.
However, in some cases it would be more convenient to use all four frame positions *in sequencial order*
That is what rg() is for. It is literally the same as range() but with rearranged variables as shown above.
This is useful for adding effects, or when you need to be precise all the time. Here is an example of one of my recent uses:
Code: Select all
c0=as("UNCOMPRESSED.avi").yv().Levels(0, 1.00, 270, 0, 300)
c1=c0.Levels(0, 1.00, 290, 0, 300)
c2=c0.Levels(0, 1.00, 280, 0, 300)
c3=c0.Levels(0, 1.00, 270, 0, 300)
c4=c0.Levels(0, 1.00, 250, 0, 300)
credits = as("CREDITS_NEW.avi").yv()

c0
rg( 116, 138, 138, 182,c1)
rg( 182, 212, 212, 239,c1)
rg( 212, 260, 294, 356,last.Levels(0, 1.00, 260, 0, 300) )
rg( 322, 386, 394, 430,c2)
rg( 435, 445, 493, 537,c3)
rg( 547, 570, 756, 801,c4)
rg( 756, 801, 826, 826,last.Levels(0, 1.00, 270, 0, 300))
rg(1255,1274,1322,1366,c4)
rg(1408,1408,1772,1796,c3)
rg(1796,1811,1900,1960,c2)
rg(1960,2014,2014,2045,c2)
rg(2412,2469,2618,2657,c2)
rg(2657,2676,2726,2775,c2)
rg(2775,2799,2824,2851,c3)
rg(3715,3787,4169,4193,c2)
gradfun2db
trim(0,5443)++credits

In this case I wanted to make select scenes in my AMV glow a bit by boosting their luma. I knew exactly when I wanted the levels to start changing, so it would have been annoying and confusing to type something like the following for each segment:
Code: Select all
range(1811,1900,c2, head=1796, tail=1960)
