Computer Chugging with 4k Footage from Gh5

Recommended Posts

Posted · Original PosterOP

Hello All,

 

My work computer really seems to chug when I am editing 4k footage from my Gh5, I am curious if it is my hardware. I edit in Premiere and I know I can make proxies to help solve this issue, I just wanted to see if there was something else I could try before I switch up my workflow.

 

PC Specs (Dell Precision Tower 7810):

 

CPU - Intel Xeon E5-2620 v4 @ 2.10Ghz

GPU - Quadro P4000

RAM -  32gb

 

Thank you for reading!

Try editing in 1080p and how is that ?  Is it much faster ?

This will eliminate the graphics card out of the solution.

Your Xeon is great for rendering with all its cores, but its old microarchitecture and slow clock speed will make timeline scrubbing a pain.


I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

 

Primary PC:

i7 8086k (won) - EVGA Z370 Classified K - G.Kill Trident Z RGB - Force MP500 - Jedi Order Titan Xp - The venerated Hyper 212 Evo (with RGB Riing flair) - EVGA G2 650W - Black and green theme, Razer branwashed me.

Draws 400 watts under max load, for reference.

 

Linux Proliant ML150 G6:

Xeon X5560 - 24GB ECC DDR3 - Asus DirectCU GTX 760 - old Seagate 1.5TB HDD - Dark moded Ubuntu (and Win7, cuz why not)

try making proxies on import. This will make a version fo the footage that is lower resultion with a much easier to play codec, then use the orginal footage again when you want to export it back out. Id use something like the 720p cineform proxy option in premiere.

I mean 2.1Ghz is not very good.  That is holding you back big time.

Thanks all for the replies!

To answer some questions yes 1080 is no problem it is only when I use 4k that it chugs.

I kind of thought it might be the CPU

It definitely does seem like proxies will be my go to from now on.

 

Thank you again everyone!

Are shooting in the 150mbps 4k 10-bit or the 400mbps 10-bit 4k? or one of the 8-bit formats? I had a hardtime getting my Ryzen 2700X system to keep up with it but it is because I was shooting the 150mbps format which is longGOP compression and is much more CPU intensive in playback since the CPU is "creating" all of the frames in between the keyframes. The GH5 has been notorious for producing footage that is a pain to edit in premiere.

 

 

I do have better luck with the 400mbps 4K format since it is All-I which means the CPU isn't having to "create" any frames between key frames and is rather opening separately compressed frames. But I still do have timeline scrubbing and playback issues more occasionally than I would like. I think it has more to do with reading larger compressed files than the size or resolution of the files because I have raw 6K Red Scarlett footage that I can edit with no problems.

 

 

I love my GH5 but I hate working with the footage.

Interesting, i will give this a shot! I have actually been trying out Davinci Resolve 16 for the last month and it has very few issues with playback.
