1) Run ripbot
2) Go see something on tv 3) Restart ripbot

@Atak_Snajpera
The trend is the same. Did a avsmeter test with Degrain2 on a UHD source. CPU: AMD Ryzen 7 (1700x) (8C/16T) @ 3.8Ghz MDegrain2 + Prefetch(16) MDegrain2 + PRefetch(12) MDegrain2 + Prefetch(8) MDegrain2 + Prefetch(4) Look at the FPS Avg and avg CPU. I think it scales different on a AMD CPU then on Intel. Running with 8 threads gives me 100% CPU when doing a real encoding. Last edited by GZZ; 21st January 2018 at 17:49. |

Interesting... I see the same performance drop on UHD as well
MDegrain2 + Prefetch(16) MDegrain2 + Prefetch(8) However when you downscale from UHD to FHD... Spline36Resize(1920,800) + MDegrain2 + Prefetch(8) Spline36Resize(1920,800) + MDegrain2 + Prefetch(16)

But if you open the Setting's tab (within Ripbot), and on the 1st main page. on the right hand side, the very top option is to use Auto Update...make sure that's checked/ticked, and you should then get ALL the updates that Atak posts. One way to check if you have downloaded any updates after opening Ripbot, is check in the Updates folder. If there's some files in there, the next time you start Ripbot, they will be installed (you see it doing this) Cheers |

I would not say that it scales badly. It scales quite well. Limiting prefetch value to physical cores should give more predictable performance in all resolutions.

I am doing forced HDR to SDR and converting from 4k HEVC to 1080p AVC. No other filters are being used. I am on a Threadripper 1950x and am seeing ~10% utilization so my encode times for a 2 hour movie exceed 5 hours (roughly 9.75fps). What is the bottleneck here?

Probably tone mapping algorithm in ffmpeg. Resizing is also single threaded. Use DE mode with extra servers.

Indeed. Problem is when Im doing a DE encoding and the core count is different across my servers. If I could set the core count on server level or have a global flag to auto detect core count on DE servers. Then it would be perfect.

Encoding server will reduce prefetch value according to detected number of physical cores instead of logical cores. If you have auto-update enabled then you should get an update shortly... Ps. make sure that all your PCs will be using updated encodingserver.exe

UPDATE: Looks to be a ~40% improvement in speed. Went from around 9.75fps to 12.80fps. Not exactly setting the world on fire, but 3:50 beats 5+ hours any day of the week. UPDATE: Turns out that last update was me accidentally doing an encode to HEVC. When re-tasked with AVC for the encode, the improvement looks like 9.75fps to 13.45fps. Surprisingly the HEVC and AVC encode speed are very similar when enabling the tone mapping process. Without tone mapping the difference in speed is quite appreciable.

Is it possible to encode from a mapped drive in Windows? I store all of my movies on my NAS and I am currently copying the file to my local machine to encode it, but it would be so much more convenient to work the source file straight from my NAS. I know someone brought this up before, but I never saw a resolution.

Why 6 servers? Because I need 3 on my 8C/16T CPU to get ~90% usage with active tone mapping.

Atack,
so any idea how to fix that green preview frame with DVD decoding? It is mpeg2 codec to blame. I fastracompressed source mpeg2 mov to Lagarith Lossless avi in VirtualDub FilterMod, then it was ok in Ripbot264. Win 10 pro x64, ripbot264 updated. Thanks in advance. |
