Can't get ApplyRange to work in Avisynth

[VideoFanatic]

My video is 720 x 480. I want to crop some garbage from it. When I use the following I get this error: "filtered and unfiltered video frame sizes must match".

ApplyRange(0,149,"Crop", 0,0,30,0)
ApplyRange(0,149,"AddBorders", 0,0,30,0, $000000)

If there's an easier way to set different settings on different sections of a video then please let me know.

[Alex_ander]

Smth like this:

trim(0,149).Crop(0,0,-30,0).AddBorders(0,0,30,0,$000000)++trim(150,0)

or:

trim(0,149).Letterbox(0,0,0,30,$000000)++trim(150,0)

Probably you could also use Letterbox within ApplyRange(), since it doesn't change frame size for separate parts of video, just covers it with borders.

P.S. Don't forget to use (-) in Crop() for right/bottom numbers.

You can't change frame sizes within an ApplyRange() clip, which is what you're doing with "Crop" inside the ApplyRange statement.
Crop and Add Borders before using ApplyRange, or Crop+AddBorders and then Trim. You can always rejoin sections into the main AVI later.

[VideoFanatic]

trim(0,149).Crop(0,0,-30,0).AddBorders(0,0,30,0,$000000)++trim(150,0)

or:

trim(0,149).Letterbox(0,0,0,30,$000000)++trim(150,0)

Thanks. That works. I read the trim documentation but I didn't really understand it. I understand the example you gave me but what does the ++ part do? Is that for adding a new trim? Do I have to keep it on the same line? If I have a 3rd trim do I have 3 pluses?

Avisynth's scripting language provides + and ++ operators as synonyms for UnalignedSplice and AlignedSplice respectively.
http://avisynth.org/mediawiki/AlignedSplice

When using trim you specify the start frame and the end frame of the section you want to keep.
Trim(0,149) keeps frames 0 to 149 of the clip.

If you specify Trim(start frame, 0), the "0" as the end-frame means there is no end frame -- got all the way to the end.
Trim(150,0) keeps frames 150 thru the end of the clip.

[manono]

As far as I know you only need to use '++' if there's audio in the script. Without audio a single '+' between trims is enough to add them all together.

[VideoFanatic]

I don't want to cut anything from my video, I just want to use different settings on different parts of the video. The trim documentation seems to indicate that trim is for cutting parts out of a video. All I'm looking for is the easiest way to use different settings on different part of the video.

I tried using apply range and I can get it working with tweak but not RGBAdjust. It says invalid arguments to function "ApplyRange":

ConvertToRGB32(interlaced=true) 
ApplyRange(0,18234,"Tweak",0,0.8,10,1.1,False,"RGBAdjust", 0.9, 0.9, 0.8, 1.0, 0.0, 0.0, 0.0, 0.0, 1.00) 
converttoyv12(interlaced=true)
ApplyRange(18235,73155,"Tweak",0,0.8,10,1.1,False,"RGBAdjust", 0.9, 0.9, 0.8, 1.0, 0.0, 0.0, 0.0, 0.0, 1.00)

The script you were given will do what you want. It cuts a part out, modifies it, then pastes it back in.

[VideoFanatic]

Could you please give an example as I'm still a bit confused.

[jagabo]

You were already given examples in post #2.

trim(0,149).Crop(0,0,-30,0).AddBorders(0,0,30,0,$000000)++trim(150,0)

Translation:

WhateverSource()

part1 = trim(0,149) # make frames 0 to 149 into a separate video
part1 = Crop(part1,0,0,-30,0) # crop that separate video
part1 = AddBorders(part1,0,0,30,0,$000000) # addborders to that separate video

part2 = trim(150,0) # create another video with frames 150 to the end of the original video

return(part1++part2) # append part2 to part1 and return them

[poisondeathray]

IMO, trim is the easiest, most intuitive way to do what you're trying to do (apply different filter settings to different sections) . ApplyRange doesn't work with all filters

[VideoFanatic]

trim(0,18234). Tweak(Hue=-0, Sat=0.7, Bright=10, Cont=1.1, Coring=False). ConvertToRGB32(interlaced=true). RGBAdjust(0.9, 0.9, 0.8, 1.0, 0.0, 0.0, 0.0, 0.0, 1.00). ++trim(18235,0). Tweak(Hue=-0, Sat=0.7, Bright=10, Cont=1.1, Coring=False)

I have the above script but I'm getting an error which says script error, expected function name following `.' It says the error is after the 2nd ++ in the 2nd trim.

[poisondeathray]

Take out the period before the "++" , right after the endbracket of the RGBAdjust (you have an extra period)

[VideoFanatic]

Now it says "Splice: video formats don't match"

[poisondeathray]

converttoyv12(interlaced=true) after the RGBAdjust endbracket. Add back the period after the endbracket, before the converttoyv12(interlaced=true)

does it make sense to you why you add this back ? You should try to learn the reasoning behind this

[VideoFanatic]

Yeah it makes sense, I just forgot to add it for some reason.

trim(0,18234). Tweak(Hue=-0, Sat=0.7, Bright=10, Cont=1.1, Coring=False). ConvertToRGB32(interlaced=true). RGBAdjust(0.9, 0.9, 0.8, 1.0, 0.0, 0.0, 0.0, 0.0, 1.00).converttoyv12(interlaced=true) ++trim(18235,0) Tweak(Hue=-0, Sat=0.7, Bright=10, Cont=1.1, Coring=False)

It's working now. Does it matter if I have a period before the last tweak? Having it or not doesn't seem to make a difference.

[poisondeathray]

Really? I think it should matter . Using the period to include everything on one line is the same thing as breaking it out

e.g

WhateverSource()
Filter1()
Filter2()

is the same thing as

WhateverSource() . Filter1() . Filter2()

[manono]

Does it matter if I have a period before the last tweak?

Yeah, it matters. Why not have the Tweak on its own for the entire film since it's the same in both instances? That way you don't have to have it twice, in each of the 2 parts being trimmed.

[VideoFanatic]

trim(0,18234). Tweak(Hue=-0, Sat=0.7, Bright=10, Cont=1.1,  Coring=False). ConvertToRGB32(interlaced=true). RGBAdjust(0.9, 0.9, 0.8,  1.0, 0.0, 0.0, 0.0, 0.0, 1.00).converttoyv12(interlaced=true)  ++trim(18235,0) Tweak(Hue=-0, Sat=0.7, Bright=10, Cont=1.1,  Coring=False)

What I'm saying is that the functionality of the script seems to remain the same whether I include a period before the last weak or not.

I know the tweaks are the same, I'm just using it as an example.

Is there no way to have each part of the script on a new line? I tried that with and without the periods and it didn't work.

Also if I want to do multiple trims then do I just add the following onto the end (and change the values)? ++trim(18235,0)

[VideoFanatic]

I'm not sure what I've done wrong here but when I change the tweak values or RGBAdjust values for one trim it also changes it for the other:

trim(0,18234). Tweak(Hue=-0, Sat=1.0, Bright=0, Cont=1.1, Coring=False).
ConvertToRGB32(interlaced=true). RGBAdjust(1.0, 1.0, 0.9, 1.0, 0.0, 0.0, 0.0, 0.0, 1.00)
.converttoyv12(interlaced=true) ++trim(18235,0). Tweak(Hue=-0, Sat=1.0, Bright=130, Cont=1.1, Coring=False)
ConvertToRGB32(interlaced=true). RGBAdjust(0.9, 0.9, 0.8, 1.0, 0.0, 0.0, 0.0, 0.0, 1.00)

[manono]

What I'm saying is that the functionality of the script seems to remain the same whether I include a period before the last weak or not.

What you're saying is wrong. Without the period the Tweak isn't used.

And once you have 3 or 4 Trim statements (and begin getting all confused, as you seem to be doing), for me the RemapFrames filter with ReplaceFramesSimple is way easier to use.

[VideoFanatic]

Could you please give an example script for that?

[manono]

I've done it before in a thread of yours:

https://forum.videohelp.com/threads/346908-How-to-Encode-Parts-of-a-Video-at-Different-...le#post2168390

Or, even more explicitly, in a different thread (easy to find by searching):

[sanlyn]

mm, if Trim() is that difficult, ReplaceFramesSimple won't be easier IMO. But it requires two clips, one of which could be created in the script.

Vid1=AviSource (or whatever source)
vid2 = vid1.trim(0,18234)
vid2.ConvertToRGB32(interlaced=true).RGBAdjust(0.9,0.9,0.8,1.0,0.0,0.0,0.0,0.0,1.00).converttoyv12(interlaced=true)
vid3=ReplaceFramesSimple(vid1,vid2,mappings="[0 18234]").Tweak(Hue=-0, Sat=0.7, Bright=10, Cont=1.1, Coring=False)
return vid3

And how is vid1/vid2 any different from BaseClip/SourceClip? Or from A/B for that matter? Call them what you will. And by writing the script the way you did you've prevented any other filtering either before or after using ReplaceFramesSimple. Its worth it's weight in gold when you have to call the same filter about 10 different times within the same video. For something like that Trims are more-or-less useless. Here is a typical one for me, trying to get the brightness/contrast/levels looking better during one stage of a VHS to DVD project. I defy you to do this using Trims:

Instead of a sequence like:

SourceClip=SourceClip.Tweak(Cont=0.90,Coring=False  )
ReplaceFramesSimple(BaseClip,SourceClip,Mappings="[37113 47556] ")

Isn't this much clearer?

ReplaceFramesSimple(last, Tweak(Cont=0.90, Coring=False), Mappings="[37113 47556]")

Or, if you want the filter sequence on its own line, something like:

filtered=Tweak(Cont=0.90,Coring=False  )
ReplaceFramesSimple(last,filtered,Mappings="[37113 47556] ")

[sanlyn]

Yes, one could refresh Source Clip and Base Clip forever, and work a different process with each batch of frames. Eliminate the return statement, replace Vid1/Vid2 with Base Clip/Source Clip (or whatever), and Vid3 reference isn't needed. Tried to keep it shorter for holygamer.

Could be even shorter by using one and the same Tweak near the end and applying it to all the previous frame groups if relevant. Alas, I've had to work on video that required 5 minutes to be broken into a dozen 30 to 100 frame clips, each requiring a different fix. Not fun.

[manono]

Isn't this much clearer?

ReplaceFramesSimple(last, Tweak(Cont=0.90, Coring=False), Mappings="[37113 47556]")

Yes, and I was trying to figure out some reason it wouldn't work, but couldn't come up with one. I just grab my scripts from people that know more than I and this way to set it up has worked nicely for me. I have templates with it included, and I just cut and paste when I need more, and change the filters used and the frame numbers. Thanks, this will make it simpler for sure.

Assuming at least some of the time you're using the same filter for different groups of frames, ReplaceFramesSimple is what you want, I think. Trimming out everything is a nightmare, and I just hate ApplyRange.

[sanlyn]

No, usually the corrections are completely different for each frame group -- one of those really bad VHS sources that has different grunge and levels in every scene change. But assuming I could use the same fix for different groups, yes, one line with one fix and different frame groups would do it.

But now I'm wondering what this statement is doing:
RGBAdjust((0.9,0.9,0.8,1.0,0.0,0.0,0.0,0.0,1.00)

The first two "0.9" parms reduce all red and green RGB values by 10%. The "0.8" reduces all blue values by 20%. The values that follow do nothing. Wouldn't the overall effect be to make the clip a bit more more yellow and visibly darker overall? It would be nice if holygamer had let us know exactly what correction is wanted.

[jagabo]

I tried using apply range and I can get it working with tweak but not RGBAdjust. It says invalid arguments to function "ApplyRange":

ConvertToRGB32(interlaced=true) 
ApplyRange(0,18234,"Tweak",0,0.8,10,1.1,False,"RGBAdjust", 0.9, 0.9, 0.8, 1.0, 0.0, 0.0, 0.0, 0.0, 1.00) 
converttoyv12(interlaced=true)
ApplyRange(18235,73155,"Tweak",0,0.8,10,1.1,False,"RGBAdjust", 0.9, 0.9, 0.8, 1.0, 0.0, 0.0, 0.0, 0.0, 1.00)

ApplyRange() can only be used for one filter. You'll have to use separate calls for Tweak() and RGBAdjust(). Oh, and Tweak() only works in YUV, and RGBAdjust() only works in RGB.

ConvertToYV12()
ApplyRange(..."Tweak"...)
ConvertToRGB()
ApplyRange(..."RGBAdjust"...)
