AviSynth Q&A - Page 12

Also note, a function with a Float arg will accept an int [v2.60+, converted to type float inside the function],
but a function with a type Int arg will NOT accept a float.

A type float arg specifier basically means 'numeric' whereas type Int is strictly int.

Thanks StainlessS. Appreciate your input.

Edit: Nevermind, Disregard that qusstion as it turned out that Avisynth + and Avisynth wer ein conflict with each other. I was using AVSPmod and it does not detect AVISynth +. My next questions are: How do I make AVSPMod use AVISynth +? And can AVSPmod be a substitute for Virtualdub2? I used the Universal Installer but I installed the latest version of AVISynth + but I am afraid to use it.

Is there a filter/function/script in Avisynth that will take the average of an entire clip? That is, to create a single frame from a clip, where each pixel in the result frame is the average of all pixels in that position in the clip. The result could be a clip containing 1 frame (ie 32-bit float), or to write the result to a file, fx TIFF in 32-bit float format?

I am only aware of temporal filters that return the average of 3 to 7 frames at a time, for each frame in a clip (TemporalDegrain(), MedianBlurTemporal(), ex_median(), etc.).

The next question will be if this can be done with other statistics, for example maximum, minimum, median?

My objective for this is to create a single-frame mask for a clip that isolates specific areas according to the statistic - for example the areas of an image that are consistently dark for the whole scene. (assuming the clip contains a single scene)

ClipBlend:

Code:

#Or to get a single frame average of all frames in a clip:
AviSource("blah.avi")
ClipBlend()
Trim(FrameCount-1,-1)

Float is not supported only 8-bit and 16-bit stacked.

Fjord · 20th January 2023, 09:04

Thanks @Reel.Deel. Spot on!

Given that I have 10-bit source (YUV442P10), I assume I should use source.ConvertToStacked() as input to ClipBlend16(), to use all 10 bits in the process (assuming no overflow in the accumulator). Do I need to convert to YUV444P16 first?

I'll add my vote for HBD support for ClipBlend, and option for running maximum or minimum. Internal 64-bit float accumulator would also be nice.

Almost, you need ConvertBits(16) first 'cause ConverttoStacked() only accepts 16bit planar as input as it will divide it in 8bit MSB and 8bit LSB.
Using the Reel.Deel example, in your case it would be like:

Code:

#Indexing the 10bit planar source
LWLibavVideoSource("whatever.mov")

#Going to 16bit planar
ConvertBits(16)

#Go to 16bit stacked (MSB and LSB)
ConverttoStacked()

#Work with 16bit stacked precision
ClipBlend16()

#Go back to 16bit planar
ConvertFromStacked()

#Final result with 16bit planar precision
Trim(FrameCount-1,-1)

Just in case, if/when they'll add 16bit planar support, make sure not to remove 16bit stacked support in the meantime as otherwise it won't be possible for legacy Avisynth versions like 2.6.1 to work in high bit depth and also filters that might depend on it.

Cheers,
Frank

Maybe StainlessS will see this. I've been on the his waiting list for almost 2 yearssS

If you need 32-bit you can do it with expr but you will have to modify the AvgAll_16 script.

That's basically the purpose of SceneStats. Generally it's for scenes, but you can also run ClipStats to get global statistics (min, max, median, mean, etc). ClipStats usually hangs AVS+ though (AvsPmod maybe?).

Do you change the name of the folders as well?

Emulgator · 29th January 2023, 19:43

Yes, you would match these folder names as given in script.
Or choose your own folder names and match script.

LeXXuz · 10th March 2023, 14:14

I have another syntax question.

Is there any difference between these 3 script snips:

1)

Code:

PRE1=filter1()
PRE2=filter2(PRE1)
filter3(PRE2)

2)

Code:

filter1().filter2().filter3()

3)

Code:

filter1()
filter2()
filter3()

If so, I'd appreciate a thorough explanation.
It would help me to understand some of the more advanced scripts any better.

DTL · 10th March 2023, 17:35

With 1) you keep 'last' unchanged untill 3rd line.

3) overwrite 'last' in each line.

I see. So, if I'm only interested in what happens at the very end of those scripts after the last line, the output of all 3 is equivalent?

I think there are other unseen "differences", like in caching behavior.

Anyway, why this thread is treated like "Ask any question about AvS" thread, when it's about AvS wiki?

My apologies. I misunderstood this thread. Will post questions about AVS somewhere else in future.

StainlessS HeartlessS Usurer Join Date: Dec 2009 Location: Over the rainbow Posts: 10,878	Also note, a function with a Float arg will accept an int [v2.60+, converted to type float inside the function], but a function with a type Int arg will NOT accept a float. A type float arg specifier basically means 'numeric' whereas type Int is strictly int. __________________ I sometimes post sober.

GAP Registered User Join Date: Sep 2020 Posts: 133	Edit: Nevermind, Disregard that qusstion as it turned out that Avisynth + and Avisynth wer ein conflict with each other. I was using AVSPmod and it does not detect AVISynth +. My next questions are: How do I make AVSPMod use AVISynth +? And can AVSPmod be a substitute for Virtualdub2? I used the Universal Installer but I installed the latest version of AVISynth + but I am afraid to use it. Last edited by GAP; 18th January 2023 at 14:06.

Fjord Registered User Join Date: Dec 2005 Location: Denmark Posts: 51	Average an entire clip, return 1 frame Is there a filter/function/script in Avisynth that will take the average of an entire clip? That is, to create a single frame from a clip, where each pixel in the result frame is the average of all pixels in that position in the clip. The result could be a clip containing 1 frame (ie 32-bit float), or to write the result to a file, fx TIFF in 32-bit float format? I am only aware of temporal filters that return the average of 3 to 7 frames at a time, for each frame in a clip (TemporalDegrain(), MedianBlurTemporal(), ex_median(), etc.). The next question will be if this can be done with other statistics, for example maximum, minimum, median? My objective for this is to create a single-frame mask for a clip that isolates specific areas according to the statistic - for example the areas of an image that are consistently dark for the whole scene. (assuming the clip contains a single scene)

Fjord Registered User Join Date: Dec 2005 Location: Denmark Posts: 51	Thanks @Reel.Deel. Spot on! Given that I have 10-bit source (YUV442P10), I assume I should use source.ConvertToStacked() as input to ClipBlend16(), to use all 10 bits in the process (assuming no overflow in the accumulator). Do I need to convert to YUV444P16 first? I'll add my vote for HBD support for ClipBlend, and option for running maximum or minimum. Internal 64-bit float accumulator would also be nice.
