I'll see if there is anything we need in r3.

Here is a port of r3 to Avisynth. Frame properties passthrough has also been added. Please advise if this is working properly.

Not sure if the file is corrupted or what but I can't open the file, the size is only 34k.

That's the correct size. Works fine for me. What happens when you try to open it?

Anyone else having problems?

I can open other rar files just fine, I tried downloading it in a different browser and same problem .

7-Zip
---------------------------
Can not open file 'C:\Users\Downloads\vscube_13.rar' as archive
---------------------------

Edit: not sure was going on but https://extract.me/ opens the file just fine. The rar file has one binary named "vscube.dll".

That's correct. Is the DLL working?

I deleted the rar and put a zip instead. Is it better?

Zip works just fine, thanks. I will test it and get back to you if I find any problems.

Thank you. Could be a RAR versus RAR4/5 thing.

Are you using WinRAR or 7zip?

I'm using 7zip. I tested the DLL and used a simple LUT and it's working like it is supposed to. Have not checked frame properties.

[videoh]

OK, thank you.

Thanks. It's working properly here.

That only x86 or x64 ver? Can you support both? I remember old ver support both. Thanks

RD,
I just noticed that 7zip posted update Dec 2021,
v19.00 was latest [EDIT: stable] for a long time, then updated in Nov 21 and again in Dec 21,
perhaps part reason was some RAR thingy.
7zip:- https://www.7-zip.org/

EDIT: Non beta, ie stable, v21.07 [26 Dec 2021]

You're probably right. My 7-zip was super old. I went ahead and updated. Thanks for pointing that out.

Can you provide the source code please?

The example from Avisynth wiki seems to be wrong:

DGSource("THE GREAT WALL.dgi", fulldepth=true)
z_ConvertFormat(pixel_type="RGBP16", colorspace_op="2020ncl:st2084:2020:l=>rgb:linear:2020:f", dither_type="none")
Cube("...\test.cube")
z_ConvertFormat(pixel_type="YUV420P16", colorspace_op="rgb:linear:2020:f=>2020ncl:st2084:2020:l", dither_type="none")

Converting to linear produces errors. Maybe a bug? Without linear the reults are fine for me:

z_ConvertFormat(pixel_type="RGBP16", colorspace_op="2020ncl:st2084:2020:l=>rgb:st2084:2020:f", dither_type="none")
Cube("...\test.cube")
z_ConvertFormat(pixel_type="YV12", colorspace_op="rgb:st2084:2020:f=>709:709:709:l", dither_type="ordered")

I copied the example that was included in avscube v1.1. I did not test it nor do I have a lot of experience with hdr. If it's indeed wrong I will update the wiki accordingly.

Yes, of course. When I release it there will be both versions.

Thank you, I will update the example. Note also that DGSource() no longer takes a fulldepth parameter.

Released as version 1.3 (to track timecube version):
