Carlo Posted March 8 Report Share Posted March 8 Hi, I'm having a lot of problem with hap reproduction. the system I'm using is: Intel i7 11k processor 8 core Msi z590 pro 512gb pcie Samsung 970 for os 2tb pcie Samsung 970 for WO 32gb Corsair 3600rpm ddr4 ram Corsair fully mod 750w gold power supply AMD pro wx 9100 16gb graphic card I'm using 6 out in almost each server, but in some way there are something strange because the file that works best right now is a prores 422. I've already read that the driver i should use are the 17Q4 but with those driver windows just crash and start with a green screen Without the ability to do anything else. Right now I'm trying the new driver but it doesen't work. It happend with HAP, HAPQ In almost the same way. the resolution of the file are multiply of 4 (Since I've read somewhere that sometimes also that can be an issue.) I really have no more idea on what i can do Also because prores is much more heavier in reproduction but it works fine with a 11000px x 1080px file. Someone have any ideas? Thank you Quote Link to comment Share on other sites More sharing options...
jfk Posted March 8 Report Share Posted March 8 Sounds like what happens if you install VLC on the computer, Anyway, WATCHOUT version? Is it happening on Production (watchmaker) or Display (watchpoint)? Do the videos play with color issues? Same on both watchmaker and watchpoint? Please describe the actual problem in useful detail.

Carlo Posted March 8 Author Report Share Posted March 8 It the last release, 6.7.2 it happens on the display computer and there are no color issue. The video are just jerky in playback. If i'm try to watch the video, on the same server with a player like jonkyo player it works fine. It's something that happens constantly, during all of the duration of the media file. I've encoded the files without audio and the server run windows 10 with all of the tweaking list done and checked. Quote Link to comment Share on other sites More sharing options...

How many chunks are you using? Frame rate factors into the chunk requirement as well, what is the frame rate? For 11,000 x 1080 @ 60p I would try six chunks.

Carlo Posted March 8 Author Report Share Posted March 8 I've the same problem with smaller file, I've tried with 2, 4 and 8 Chunks the framerate is 30p and i never reach a good playback. Also because I've tried in a 8 year older build and it works without problems. Quote Link to comment Share on other sites More sharing options...

So that would appear to rule out WATCHOUT and the movie file. With those items verified, and the same movie specs play smoothly in ProRes but not in HAP, that truly is unusual. Hard to guess where your build has gone awry. I have never heard of the gpu driver affecting smooth playback, color issues yes, but not smooth playback issues. I defer to those who build PC servers ... Quote Link to comment Share on other sites More sharing options...
RBeddig Posted March 10 Report Share Posted March 10 Well, I normally don't argue with jfk, but especially with HAP and AMD graphic cards we have seen those issues since 2018. The reason seems to be that AMD introduced some sort of energy saving mechanism in their drivers, throttling the performance down when the rest of the computer is almost idle. H264 and ProRes use the CPU for rendering and they consume quite a lot of CPU power while playing HAP files can get unnoticed by the CPU. Playing a HAP fullHD@60fps leads to some 2% CPU use on our systems. To test this theory, you could play your HAP file and add some ProRes or H264 file behind your HAP. This will make the CPU busy and should hinder the graphic card driver in throttling down. Since using the old AMD driver didn't help you, you might investigate AMD drivers a bit more. I think I remember that AMD at some point brought out a separate tool to influence the energy settings of the driver but my memory could as well be wrong here.

Was not aware of the AMD energy saving concern. Wouldn’t that be variable rather than all the time? Quote Link to comment Share on other sites More sharing options...

Thank you for this answer, this is something I didn't know, most of the build I've used so far were made with nvidia card, and i never had this kind of problem. Sadly I can't check out this solution right now, because I'm abrod, but as soon i can check this out I'm goingo to came back to you. Thank you again for the answers!
