High Spec Laptop - TERRIBLE Timeline/Preview Performance

Hi All,

So after trying on cc 2014 I have better results, but still enough of the same problems to determine that you are all probably correct (no surprise there) and that these issues are likely NOT related to my hardware or Adobe, but simply the format of my original footage. As I am NOT a professional film-maker, my understanding of these details are fairly limited, and I have never transcoded or proxied anything. Don't really understand what that means or how to do it. Anyone have a good video link to a tutorial on the best settings for transcoding or working with proxies with 4k60 fps footage, specifically from GH5 or Phantom 4 Pro?

Or someone want to hold my hand and walk me through it? I am willing to try your suggestions, just not sure how to do it or where on earth to begin.

Wouldn't it be nice if I could just edit off my original files? Why not? Ugh.

Hi All,

Here's an update. After disassembly and re-pasting of the thermal compound on GPUs and CPU, no change whatsoever in any usage or temps. So I spent 2 days backing up 3TB of footage and files, formatted my c: drive and reset windows. After reinstalling all my programs (headach) I load my PRP timeline. During playback CPU usage is now maxing out around 80% - 85%! WOOHOO! I suppose some hacker had CPU jacked my PC for mining. Now it runs so much cooler, and never comes near the previous 99%... and yet.

SAME. EXACT. PROBLEM. (face-palm).

So now with all hardware running at very very very reasonable usages (CPU around 80% during playback, disks, RAM, and GPUs also barely touching 40% usage and staying well cooled... I am left with the conclusion that the new CC simply is much worse at handling this footage, as PRP 2014 was butter smooth on this exact same machine.

I am going to experiment with this proxy footage (why do I have to bother wasting even more storage space with this. Surely this $650/y annual fees should be enough to get me a pro editing program that can handle GH5 and Phantom 4 footage smoothly with my overkill hardware.... especially given that the old PRP 2014 handled this perfectly....)

I will also look over all your suggestions and see what else can be done. In the meantime.... also reinstalling PRP 2014 and canceling my annual subscription. Paying for what...? THANKS ADOBE!

Yep I'm running windows 10. Legit versions all around.

Just tried to see if I had any different results with some phantom 4 pro footage. .mov files at 4K @60fps. Exactly the same. Hundreds of dropped frames. I always close all programs in the background... but again. I have 32GB of RAM. I have even set a system reserve of 12gb of ram. That means PRP has access to 20GB of RAM..... That's nearly triple what my old laptop had and that machine had no problem with footage of any kind.

So I may have found the bottleneck, but I still don't understand why it's causing a slow down. On half quality preview, during timeline playback, all of my drives hover at 1%-5% usage. Ram is around 25%. However CPU jumpsup to 90%, or even 95% when it gets real slow. On simple titles it drops back down to around 50%. With footage its jumps back up to 90%, then hovers around 85%.

I'm going to contact their support and see if they can walk me through my troubles. There is no reason this should not be butter smooth.

Hi everyone,

Thanks for the feedback, but this is not resolving this question. There is no question about my drives being too slow. Having my OS split between 2 m.2 drives is how the laptop came from the factory, and moving it to one makes little sense as it would cut the speed. RAID 0 across 2X 256 GB lite-on M.2 drives gives me insane speeds for read/write for OS and applications. I am not concerned about data loss as everything is backed up onto an external 20TB RAID 0.

Codec is standard GH5 .mov file. I am using the 8Bit 3840 x 2160 @ 60 fps codec. I am not converting before importing into premiere pro. I think my computer should be able to handle it, yet I am having this laggy playback even with 1080p footage.

Have tried with 1 screen, 2 screens, 3 screens and even 4 screens (i know, its overkill, but I love multi-monitor workflows). No change in performance. Preview is set to 1920 x 1080. Changing from full to half to quarter etc has no effect. Im so annoyed.

Still wondering what could be wrong.

Ideas? Anyone from Adobe want to help with this?

Move your footage onto the raid0, or at least give it a try.  What CODEC does that camera use?  It has a Panasonic ring to it.

OK, I looked it up:

The resulting images are easier to edit and work better for action sequences, but they tend to be much larger than inter-frame files. So, Panasonic introduced a 400Mbps "All-I," 10bit 4:2:2 codec, doubling the previous data rate. That's a higher throughput than many pro cameras, including Sony's $7,500 4K FS7 XDCAM, even though the GH5 costs less than a quarter the price ($1,700). As mentioned, the new data rate doesn't work yet for 6K anamorphic, and you'll probably need a high-speed UHS-II class SD card.
