Is420 returns false, but IsYV12 works. I made sure to update headers to the latest version.
From avisynth.h:
Code:
    //  YV12 must be 0xA000008 2.5 Baked API will see all new planar as YV12
    //  I420 must be 0xA000010
Run the debugger and check the actual value that is returned.

hum... now it works. Perhaps it didn't recompile properly after updating the headers.

I made a post regarding an issue with Avisynth and pixel types in combination with different bit depths here:
https://forum.doom9.org/showpost.php...&postcount=160

Quote:
Updated the first post with version 1.6.

If you extract the luminance channel such it is just the Y channel, obviously it is a different format to the YUV clip such as output from the chroma filtering. You first have to convert back to the same format before combining. This is fine, however when you are in more than 8 bits, the commands such as isYV12() etc do not work since it is expecting a YUV420Y8 clip for it to be true. Since it is a YUV420P10 clip (for example) the command isYV12() seems to give back false. If you run convertToYV12(), it keeps the higher bitdepth of 10 etc, so isYV12() still doesn't work. This, and possibly other little issues, are problematic when you want to have the output clip the same format as the input clip and it isn't 8-bit etc. This is why I put back the 'do not process' flags to the luma commands, it was either that or dropping support for YV16 and YV24, which obviously isn't desirable.

It works fine as is because the bit depths can be matched easily and the pixel type hasn't changed. I could do a convertbits() just so isYV12() etc works, but then it's an extra unnecessary bit of processing that will probably affect speed more than what was gained by converting it to Y8 and going back to the desired pixel type.
Imagine a source of YV16 and 10 bit. If you extract the Y channel, process it, to merge it back to the original clip you need to first convert it (can't do a direct merge chroma). To do this, you need to know the format of the original clip, which is problematic because isYUV() works, but isYV16() doesn't because in this case, it is really asking , effectively isYUV422P8(). The result therefore is false. Am I missing something, or do you really have to go isYV16(Convertbits(8)) first so it answers true if a bit depth other than 8 for YUV4224Px? If this is true, then it is NOT consistent with convertYV16(), since that keeps the bit depth. You can literally go ConvertToYV16() followed by isYV16(), and it will return false if it isn't 8 bit.

Use IsYUV420(), IsYUV422() and IsYUV444()

Was looking for a link but can't find those commands in the docs!

EDIT: Is420 in clip properties

See my response to your first issue here. (oh hi MysteryX)
Yes, you can do a direct merge chroma, with CombinePlanes (MergeChroma should also work)
To get the format of the original clip, use Is420, Is444 etc, with BitsPerComponent.

Mergechroma didn't work, since one clip is Y8 and the other YV12 , formats have to match. Combineplanes should work though. I should have realised about the is422() etc! I'll fix this later today my time and hopefully works. Thanks for the info!

Readme file for r2508 has wrong instructions

The Readme says

Quote:
- 64 bit OS:
copy Avisynth.dll from x86 folder to the windows SysWOW64 folder
copy Avisynth.dll from x64 folder to the windows System32 folder
I think x86 goes to System32 and x64 goes to SysWOW64

No, that's the common mis-assumption. For every Windows flavour, "system32" is the place where the DLL for the native architecture goes. For compatibility reasons.

If you have a 32-bit Windows, the 32-bit DLL goes to system32. Logical.
If you have a 64-bit Windows, the 64-bit DLL goes to system32. Because of compatibility reasons.

And because a 32-bit DLL is not native to a 64-bit Windows, it goes to a special directory "SysWOW64", which is mapped to "system32" for 32-bit applications running on a 64-bit Windows in a compatibility layer.

Germans would comment: "Klingt komisch, ist aber so." (Sounds strange but is true.)

Also swiss would comment this.

Is it right to deduce (When looking at referenced installer for r2294) that this installer will handle things correctly, so no manual copying of dll is needed, and it even includes newest version of avisynth?

No, it does not have the latest version so you would have to copy the DLLs and plugins.
I suggest you use my universal installer, it has the latest version of AVS+.

Thank you. But on the download page http://avisynth.nl/index.php/Avisynthplus/Downloads, yours is referenced. So I had the correct one.

As I mentioned, if you use the r2294 installer you'll have to copy the DLLs (r2408) manually.

Plugins for high bit depth support.
Here in Forum I find docs on support of high bit depth. How can I know which plugins support this feature. In http://avisynth.nl/index.php/AviSynth%2B I find the newest version but no mention of bitdepth support.

Test if they support such input. Look into their changelogs/documentation. If they are old you know they don't.

What is old? Older than first Avisynth+ version which had high bit depth support?

Yes, that's what I meant. (I didn't mention an actual date because I don't know it from the top of my head. Maybe someone else knows.)

That's a different kind of installer. I suggest you read the first post in the thread to which I linked in post #3611.

I need
Quote:
TransAll.dll
vsfilter.dll
zoom.dll
freeframe.dll
ffms2.dll
NicAudio.dll
FFMS2.avs
vsfilter and NicAudio are probably independent of bit depth.
ffms2 seems to be the only one working, but for transall there seems to exist an alternative on vcmohans page.
freeframe is not mandatory
zoom is available as source and it should be easy to adapt it.

So I might give it a try.

Your link via post 3611 goes to https://www.dropbox.com/sh/oxx5cm9hk...jEdSjenHa?dl=0

The link on page http://avisynth.nl/index.php/Avisynthplus/Downloads goes to https://www.dropbox.com/sh/oxx5cm9hk...jEdSjenHa?dl=0

So where is the difference? Anyway, thank you for the installer. It works well.
