Problem with x265

[protoX]

I have been trying to make a proper encode with x265 (from x265.cc). I tested some 0.5 builds before.

Now however since last night, I have been trying to make a simple encode out of it. Source is a BluRay.

My AVS script

DirectShowSource("C:\axel\Encode\00023.m2ts", fps=23.976, audio=false, convertfps=true).AssumeFPS(24000,1001)
crop(0, 140, 0, -140)
Spline36Resize(1280,536)
SelectRangeEvery(500,10)

And for some reason while I give abr 4500, x265 encodes at strange bitrates and resulting file looks like this.

[Selur]

maybe they broke the 1pass abr encoding mode somehow.
Selecting 10 frames every 500 frames and thus probably having every 10 frames a scene change might be too much for the 1pass rate control.
-> Have you tried:
a. an older version of x265
b. without the SelectRangeEvery ?

[protoX]

Ok It seems there is something odd going on here. Since I mostly have 24/25 fps sources at home thats what I have used to test x265.

I made directshow change the input fps to 24 and it worked.


Old avs script

DirectShowSource("C:\axel\Encode\00023.m2ts", fps=23.976, audio=false, convertfps=true).AssumeFPS(24000,1001)
New svs script

DirectShowSource("C:\axel\Dalas.Encode\00023.m2ts" , fps=24.000, audio=false, convertfps=true).AssumeFPS(24,1)


and rest of it is same.

So x265 is having trouble with 23.976 fps or something wrong in my end?


I will grab some more 23.976 stuff to test.

[Selur]

I don't use avs4x265, I don't use Avisynth+ and I also don't use DirectShowSource, but here x265 has no problem with 23.976 content, so my guess is that is it related to your end,..

[protoX]

I am sure Avisynth+ And DirectShowSource is not the issue because I use them for x264 encode all the time.

However I will do test with avs2yuv to know if it's avs4x265.

[protoX]

Using avs2yuv 0.2 did testing again.

x265 screwed up again. To make sure it's not avs2yuv I tried to do same test with x264 with normal result.

Anyone know whats going wrong?

[El Heggunte]

I am sure Avisynth+ And DirectShowSource is not the issue because I use them for x264 encode all the time.

Downgrade to "normal" Avisynth, and see if this makes some difference

[protoX]

I have removed Avisynth+ and installed the stable 2.5.8 release. However that didn't do much help. Frames are still bad.

However I encoded a file using Hybrid, which is making proper encodes. Hybrid won't show the complete command line for encodes. Any chance I could get it to find out what's going wrong?

[vhelp]

it sounds to me that you are not feeding x265.exe a properly formated source or most likely you have a h265 decoder issue.

[Selur]

However I encoded a file using Hybrid, which is making proper encodes. Hybrid won't show the complete command line for encodes.

"Disable Jobs->Minimize job command line" and you can see the complete callls.
Also if you create a debug output file, it will also include the complete calls.
(btw. Hybrid is using latest Avisynth 2.6 MT)
