4k Video Editing System - baffled

[jrmarsh]

I'm trying to get setup to edit 4k video, I am running the current system:
Processor: 1 x Intel® Core™ i7-4790K Processor (4x 4.0GHz/8MB L3 Cache) - Intel® Core™ i7-4790K

Memory: just upgraded to 32Gb of DDR3 Ripjaw

Video Card: 1 x NVIDIA GeForce GTX 980ti - 6GB - Single Card

Motherboard: ASUS Z97-K -- 2x PCIe x16, 4x USB 3.0, 2x USB 2.0

Primary Hard Drive: 1 x 120GB Kingston V300 SSD + 2TB 7200RPM HARD DRIVE (Videos are on 2TB Hard Drive)

Operating System: Microsoft Windows 7 Professional + Office Starter 2010 (Includes basic versions of Word and Excel) - 64-bit

When playing 4k video (shot by a GoPro) in a player like VLC it plays smoothly, when brought into an editing environment like Premiere it slows down and stutters after a few seconds. I just added 16Gb of RAM which made zero difference. I am using the Mercury GPU Acceleration Memory Playback Engine.

I don't get it 4 x 4.0 GHZ i7 + 6GB GPU + 32 GB of RAM one would think = 4k video editing.
Any help would be greatly appreciated.

Sounds like a software or driver problem. Have you tried turning off the "Mercury GPU Acceleration Memory Playback Engine"? VLC mainly uses the CPU, so that should work.

Alternatively, how does the video play in something that uses GPU drivers, like Windows Media Player?

How much GBs the files you are working with are? Tried copying a small sample video that produces stuttering from the 2 TB HD to the SSD, or making a RAMDisk and copying it there? Playing it should perform good enough since its lineal reading (Unless you're skipping and going forward/backward all over the place). I would not be surprised if edition tools loves random performance.

What is your CPU and memory usage in the two scenarios?
