By the way. Why did you use such weird number of servers? 2990WX has four numa nodes so you should use 4 or 8 servers (1-2 servers per numa node).

I need precise description what application is causing problems not some "summarization". You are not helping with that kind of bug report.

This command will restart encoding on server if ffmpeg.exe and x264.exe/x265.exe are not using cpu cycles for 1 minute. Basically I'm checking USER TIME for specific process. This value increases if application is working.

However I suspect that your issue is completely different. In your case whole EncodingServer.exe for some unknown reason hangs. I would have to write additional small application to just monitor EncodingServer.exe in this case. That's why I need to know precisely what hangs.

I used RipBot v1.23.1 to convert a 2160p HDR x265 video to a 1080p SDR x264 using the BT.2020->BT.709 Tonemap option, and while it did correct the HDR and remap the colors/levels, the end result still looks a bit too bright. Whites in very light scenes look a bit blown out, and during the end credits where the background should be pure black, it's not quite, its dark grey.
Almost like it needs TV->PC level conversion, but not quite - when I ran a second encode and added that option, then it was too dark, with blacks being crushed and losing all detail in dark parts throughout. So it needs a tweak in-between. Does anyone know if this is normal, and in that case, are there "standard" additional changes I would need to the brightness and contrast settings to get the levels correct? Or do I need to just keep doing test encodes until I find the right balance?

I selected BT.2020->BT.709 in the Avisynth options, not sure what you mean by "forcing" it, but the encoded file appears to have correctly converted the HDR to SDR. When I play the encoded x264 file back with MPCHC, if I go into the options under "video"..."color correction" and set brightness to -5, then the black levels are perfect - the credits are pure black as they should be, and the blown out light scenes look correct. So I'm assuming that I need to set brightness to whatever the equivalent is in RipBot. In MPCHC, the brightness range is -100 to +100. RipBot lets me change the brightness from -255 to +255 in the "Tweak Colors" setting. So would I set it for 5/100*255=-13??

Help Code:
Hable Usage -------------- DGHable(clip, float exposure, float a, float b, float c, float d, float e, float f, float w) exposure default: 2.0 a default: 0.15 b default: 0.50 c default: 0.10 d default: 0.20 e default: 0.02 f default: 0.30 w default: 11.2 Input must be CS_RGBPS, see z_ConvertFormat() in the script below. If 'clip' is omitted, then as usual implicit last is used. Meaning of Hable coefficients: exposure: Gain to apply. a: Shoulder strength b: Linear strength c: Linear angle d: Toe strength e: Toe numerator f: Toe denominator w: Linear white point hable(x) = ((x*(a*x+c*b)+d*e) / (x*(a*x+b)+d*f)) - e/f output_pixel = hable(exposure * input_pixel) / hable(w) Click preview script to verify your new settings before encoding.

For suspended EncodingServer.exe you would need additional precess monitoring in the same way how EncodingServer.exe is monitoring own spawned processes.

Hey Atak,
any chance of supporting OPENCL on XEONs? I got Support for OPENCL1.2 via Intel OpenCL Drivers for Xeon, works with luxmark. Ripbot recognizes it, butI canīt select it as a device for filters. Yes, itīs slow, but better than nothing and 24 Threads are better than nothing |

AFAIR the newer ones even have iGPU, but I am talking about some older Models (Dual X5650)... Intel and AMD have Support for CPU-based OPEN CL. I tryed Staxrip with NLMEANS-CL, which works fine only on CPUs...
Since X264 doesnīt scale very good over 24 threads, I use the remaining for Filtering - having the opportunity to run OPENCL Filters gives me a nice option: Sure itīs slow... But the Xeons are working in a swarm with more recent i5, i7, etc... All of them which have GPUs - so here I can use OPENCL Filters... Since the XEONs keep cyrcling in a dead loop as soon as an encode with opencl filters starts, I have to manualy take them out of the swarm (6 servers)... Would be lovely, if they participate, even if its a little slow... The OPENCL Performance with NLMEANS plus X265 "very slow" encoding of 1080p of one of these XEON Servers is around the same as a Kaby-lake i5 with the iGPU doing the openCL encoding.. |
