I overclocked the quadcore to 4.5ghz, maximum stable clock at auto voltage. Now the files play fine in timeline without sttuter, 7 files in sequence, 10bit. So it was a 18ghz total, so a computer above 18ghz should play fine in timeline.

Processor varies from 52% to 100%. I perceived when the play is near a new file the processor increases to 100% probably because the software is buffering the next file. After some seconds playing the next file the processor gets lower and varies between 52% and 73%.

So every cut is a processor intensive task. Lots of cuts near to each other can make sttuter to happen. I did a try in small cuts, 3 seconds each, and I mixed different clips cut in 3 seconds parts. The first play was full of sttuter, the second play was fine because everything was buffered to memory. So a good solution to see the editing is to do two plays. First play will sttuter, second play will be smooth.

This test was done in a 23,976 timeline. All clips was interpreted to 23,976. More FPS will mean more strong processor...

The computer just have one monitor. Size was set to 25% and quality was set to maximum. To my surprise quality set to maximum was smoother.

I believe a minimum ideal computer cpu for 4k 10bit would be a total of 26ghz to keep processor below 50% and make the editing to be smooth no matter the size of clips and the amount of cuts.

6 cores at 4.4ghz each

8 cores at 3.3 ghz each

10 cores at 2.6 ghz each

J4205 ?

So Id need a 6 core to run 4k 10bit 422 smoothly on premiere pro? right now I have i7 3770k @ 4.2 ghz and a 980 ti with 16gb ram and it starts to play them smoothly then half way into a clip or a whole clip will just be super choppy even if I drop the res. scale on pp. I was told a i7 7700k would be fine for editing in pp, a friend told me his plays back smoothly. maybe its combination of the ssd or pci ssd he has too.

@jclmedia I think there is something else going on with Adobe, I'm running it on windows my spec is further up this thread. now I've got a gh5 I've had time to play a bit more, as I put there it can play full quality with 10bit (I have 10bit monitor as well) in vlog + lut + some adjustments just fine. What I have noticed is if I ingest say 20+ 10bit clips then Adobe has a real hard time getting all the thumbnails sorted out and it really impacts the performance overall for quite some time while it sorts it's self out so I think there is probably something going on there that Adobe need to address, I did see someone else post this was a known issue they were working on but can't find a link (edit link here https://forums.adobe.com/thread/2299160)

As a workaround now Adobe can read gopro ciniform in a mov wrapper natively 64 bit with no quicktime at last! I just auto proxy to that and then flip it to proxy mode and it flys + ciniform you can preserver the bit depth so you get a really good idea about colour correction even if it's a reduced size.

So for me, it's fine at the moment, if I have a couple of clips I just want to tidy up and bang out I can with no proxy, if there are a lot and I want to edit properly I just let it proxy in the background and grab a cup of coffee. (I did try ingest and create proxy at the same time but that took longer, easier to just copy them then proxy it)

@apefos, currently fcpx works lovely with GH5. Just mentioning. No real issues apart from h265 playback. However ffmpeg does a good job of transcoding.

@eatstoomuchjam I thought that it was a h264 10 bit issue. I could be wrong. H265 from the GH5 isn't even advertised by Panasonic yet. Also h265 files that large are very demanding. Prores that large is also very demanding.

So currently 4k 10 bit files from GH5 are h264

@Umii all GH5 files? Including h264 8 bit?

Maybe try resolve until PP is fixed.

Yes, h265 is very much an issue for all but a few NLE's. However h265 is a very compression heavey correct, so conversion at some point to a proxy, or alternative format (DNXHD or Prores) is a good idea anyway. If you are on Mac then I can recommend iFFmpeg. Amazing! (Give ffmpeg a lovely simple gui).

Have you played with 60p 4k V-LogL?

hi guys, I have a quadcore, GTX1080, 64GB RAM and I just downloaded the Neumann's test footage. the clips in Premiere only show audio. Am I the only one?

I have 3 4k monitors with Windows 10 home creators edition displaying all at 4k. I get slightly choppy video when I play my timeline in Avid Media Composer. I have various media resolutions on my timeline but everything is rendered at my project setting 23.98 1080

Is my 980ti most likely the cause of this subtle choppiness when using all 3 screens and 1 playing full screen video?

cpu is 4790k w/ a z97 asus gryphon mobo (id say relatively high end) and 32gb of ram.

I'm curious about what people think. However, I'll be getting my 1080ti tomorrow. So ill post an update either way.

This seems like a nice topic to resurrect for this...

I recently got a pretty maxed out XPS 15 9570 and I went for the i9 (planning to repaste it to reduce thermal throttling issues) (disclaimer: my day job is for a company which is mostly owned by Dell). The GPU is a 1050ti MaxQ. I imported one of my Resolve projects with a bunch of 10-bit GH5 long GOP footage and I was fairly happy at first when things were playing back at around 22-30fps before repasting (a little choppy, but tolerable) - but then I was bummed after about 10 seconds when thermal throttling kicked in and my playback rate dropped to about 6fps (pretty much unusable). I messed around a little bit with undervolting and underclocking in XTU to see if I could keep the envelope low enough to keep a relatively decent FPS without the 6fps crater and I had minimal/no luck.

Then I got curious and tried some A7R Mark III 4K footage and everything was crazy smooth playing back at 29.97fps, even with 2 LUTs and some exposure/color tweaks applied. I only let it go for about 30 seconds to a minute, but there were no signs of anything heating up too much.

I started checking resource monitor in Windows and I've noticed that when I'm trying to play back the GH5 footage, my CPU load is at about 85-90% and GPU is at about 10%. When I play back the A7R III footage, my CPU is at about 10% utilization and the GPU is at about 75-80% utilization.

I double-checked on my desktop (8700k w/ 1080TI) and the pattern stays similar - CPU is heavily-used for GH5 footage and barely gets touched for Sony footage - but the beefy/non-throttling desktop CPU is able to power its way through the GH5 footage so it stays at a clean 29.97 fps.

Has anybody else noticed this? I'm not seeing a lot of discussions about it online, but maybe I'm just searching for the wrong terms. I'm also thinking about trying Resolve 15 since I'm currently using 14 - maybe Black Magic's engineers were able to move more 10-bit h.264 processing to the GPU for the new version...

Also, now that I have this fairly nailed down, I'm going to look to see if there's a "performance mode" that cranks up the fans and try that and then I'll try repasting the CPU/GPU soon and see if that lets me keep better FPS with GH5 footage.

This should also answer the question for people looking for a new laptop to edit with Resolve - as long as you're using a codec that Resolve implements on GPU, getting a laptop with a 1050Ti should be enough to get you through general basic editing, no need for i9 (or maybe even i7). YMMV if you're doing fancier stuff than I am (lots of compositing, etc).
