I am doing some inspire 1 4K video editing, I see my desktop is very powerful, however, when I palyback the video in Premiere, it's very choppy, and not easy to do the editting, and I see my CPU got 100% occupied.

But my setting is below:

CPU : I7-4770 3.4 ghz, 8 cores,
Graphic card: nvidia GTX 660
RAM: 16G
disc: SSD 256G

Does any pros have any ideas on this?

much appreciated!!

The i7-4770 does not have 8 cores. It has 4 cores. And i think you must oppgrade your geforce 660 to minimum a 960 to do video editing in 4k

I use
i7 4720
GTX 960 - 4gb
16gb RAM
512 ssd

tried both Sony Vegas 13, and Premeire and they are both very choppy for editing . . . I'm thinking of only shooting in 1080p to overcome this from now on . . .

that's right, thank you. Do you think how many cores matters more than graphic card, bc i can tell from my usage monitor, it tells me the CPU and RAM been occupied most, not GPU.

I run an older 6 core AMD and it does just fine with the 4k, coupled with a ATI 6870.  I know this might sound obvious but have you considered reducing the quality of the playback during edit in order to facilitate a better idea of the overall outcome?

Could also have something to do with your sequence settings in Premiere.  I have a much slower computer that has some problems with 4K but works most of the time at 1/2 playback and always at 1/4 playback.  So you should not be having this issue with computer as fast as yours.

How did you create your sequence in Premiere?

At work right now but can check on my seq. settings tonight and post here.  I ran some material last night and it definitely maxed out all 6 cores on my AMD but I edit in 1/4 and its not bad.  I run 8GB ram as well and it doesn't even get to 6GB utilization so, with the amount of power in the i7 and your current setup it is more than likely a setting issue.

2.6GHZ i7 here w/ 16 mb of ram. For a 4k edit, I have to edit in 1/8 or 1/16. Sucks, but it's doable. Viewing the original media or final 4k output render is fine though. It's just viewing my timeline work.

Check your hard drive usage. Are you running everything off the same drive? Video editing works better if you have the OS on one drive, another drive for your source video, and even faster if you have yet another drive for your output video.

My desktop machine is circa 2008, 8 Gigs of RAM, 6 hard drives, and an old Core 2 Quad Q6600 (2.4Ghz), and it's able to edit 4k. Not butter-smooth, but pretty good. Not much worse than my 1 year old HP with 16GB and Core i7.

I would check to see if you're using hardware playback, not software.

Looks like a lot of people are in this same boat with editing 4k video.  I have an HP tower that is running Windows 7 Professional 64 bit with a i7 3.20 GHz processor, 12GB of ram and a GeForce GTX 750 Ti graphics card with 2GB of dedicated memory and an SSD hard drive. With this in mind it is nearly impossible to preview my 4k footage on the timeline in Adobe Premiere Pro CS6 because it keeps freezing & stuttering making it very difficult to mark the in & out points.  Also, it doesn't make much difference if I watch the timeline playback in Full, 1/2, 1/4 or 1/8 as it is still very choppy & laggy.
In addition, Premiere Pro is on my C drive and the source footage is on a separate drive.  With that said, once I have my timeline set to be exported, the video renders perfectly in a reasonable time with great results.
What I don't understand is that this same, (raw from the camera), 4k footage plays perfectly smooth in Windows Media Player?  Why does it play perfectly there but not when loaded into the timeline in Premiere Pro CS6? Does anyone have an answer to this question?

tkeeg I'm having the same problem as you with Sony Vegas, it is choppy on the lowest preview settings even using my CUDA NVidia card, yet runs fine in media player.  I have a i7 4270, 16gb ram, 512 ssd, GTX 960m with 4gb dedicated memory . . . . its driving me mental right now . . . I even tried Premiere CS6, same thing . . . I've set options to use dedicated video too . . .   if anybody can help I would be grateful . . . I've search high and low on the internet to no avail . . . .

Not that it helps all that much but after reading over this forum it seems like a lot of the issues are revolving around folks with the i7... I know that is a killer CPU for some applications but is the 4-core really hurting you that badly?  Maybe... Anyone else running north of 4 cores and getting better results? I personally run a AMD 6 core, all unlocked, and Premiere works fine...

Actually, my Intel i7 CPU 970 Processor @ 3.20GHz, 3201 Mhz, has 6 Cores and 12 Logical Processors according to the spec sheet that came with the computer.
Since it plays 4k back perfectly in Widows Media Player, why won't it play smoothly on the Premiere timeline?
There must be a reason, and like Acidsnow said, I can't find an answer either after searching the internet.
I'm fairly certain that my Premiere Pro CS6 is 64 bit to match my computer, but I'll have to confirm that later to be sure.

When starting a new sequence in Premiere, I would recommend right clicking on a clip, then clicking "New Sequence From Clip".  This should create a sequence with settings that match your initial footage.

Also, in Premiere preferences look at the "Memory" section and make sure you have dedicated enough of your RAM for use by Premiere.

Another possible cause of the stuttering might be a bottleneck in transfer speed from external hard drive.  I believe others have mentioned this.  Your processor can be the fastest in the world but if you are connecting a drive over USB2 it won't matter.  Hopefully you have a USB3, esata, or a Thunderbolt connection.

Howie, this probably isn't causing your playback problem, but in general I find it odd that your sequence is set to 29.97 and your preview file format is set to 50hz DVCpro (ntsc and pal are being mixed here).

CS6 is almost 4 years old now... Could that be an issue? I never did 4K on CS6 (I'm on CC 2014), so I don't know how it was with 4K.

I run Premiere Pro CC . Win 7 pro 64bit -  i7 4770 3.5  32Gb memory  C: drive is SSD .   Well before 4K editing I upgraded the graphics card to GForce GTX 770.  With 4K  J-K-L takes about 3 sec to start but otherwise it's acceptable.  An Adobe blogger recommend GTX 770 as a minimum for editing w/o stutter.  Upgrading the graphics card helped bigtime/

4K footage looks amazing but usually it can make video editing a real nightmare. You may get a latest 4K camera like the Blackmagic 4K, Lumix GH4, Sony FDR AX100... meanwhile your computer freezes when editing 4K video in Premiere Pro.

Granted, Premiere Pro CS6, CC 7 can handle (usually) 4K files without much problem, but it is extremely hardware intensive. Thankfully you probably don't have to buy a new computer... but you do need to convert 4K video to Premiere Pro using MPEG-2 (1080p) as primary delivery format.

This.


If you are going to skip offline editing with proxies you need to keep your OS on one drive and your media on a separate very very fast HD preferably a stripped RAID array.   It's less a matter of having  the power to decode and more about having a large enough pipe to stuff the data through.

Here's some new info that may help someone sort this out for us.

My system is fast enough to edit 4k video in Vegas 13.

I can playback 4k footage from the GH4 very smoothly in vegas and the frame rate seems to be full 25 (PAL) - no chop or lag. These files are 3840 x 2160

However, when I use files from the inspire 1, which are 4096 x 2160 and a slightly higher bitrate, I get about 1 fps. Unworkable for editing.

Both file types play fine in external media players. So what is the difference?

My system is:
i7 4970
SSD for OS and Apps
HD for source
Radeon R9 290 graphics
8G RAM

I'm running Sony Vegas Pro 12 trying to get rid of the choppy 4k preview issue.  I have a Microsoft Surface with a SSD usb 3.0 for the video files.  Shouldn't be a bottleneck.  I've tried putting the files in the media pool, then right clicking and hitting the make proxy files.  Doesn't help much.  Tried making AVI uncompressed files, then placing those on the timeline, still somewhat choppy and HUGE file sizes.  Tried transcoding to mpeg still not great.

But like others, these 4k files play perfectly on my Surface with windows media player.  Same on my desktop.  Seems odd Vegas can't play them one quarter the size smoothly.  Maybe it's a codec issue?

I finally gave up.  I play the files in windows media player to find the rough in and out points, then go into vegas bring the 4k files onto the timeline and find those points by resetting each clip start time code to zero.  I CAN fine tune in Vegas by using the left/right arrow keys to move forward and back frame by frame.  After a rough cut, I'm just going to render down to 1920x1080 30fps mp4, then use that file for editing.  HD mp4 size seems to run smoothly in Vegas.  But editing in 4k is great because cropping the Inspire 1's 4k file in Vegas down to HD dementions means you have a lens perspective choice from 20mm (equivalent 35mm) to 40mm equivalant.  I find 20mm pretty wide for some subjects so a cropped 4k really helps.  Would be nice if the DJI Go app could show an HD crop within the 4k screen.

As a matter of fact, the latest version Premiere Pro CS6, CC has the ability to handle 4K files without much problem, but it is extremely hardware intensive owing to the codec issue and resolution. To make DJI Inspire 4K files editable in Premiere easily, users need to convert DJI Inspire 4K to MPEG-2 for Premiere Pro as primary delivery format. What I used is Brorsoft Video Converter. You can have a try. Good luck

Hello folks,

It is definitively an issue with the editing software and not hardware... I have a old Lenovo T440 laptop (i5 4GB ram) and editing 4k on premiere cc was too much pain. Even playing the 4k video off the X3 with VLC was impossible.  I assumed the laptop wasn't up to it.

Then one day I found out that changing some mp4 settings in VLC made playing the X3 4k file very smooth and I started wondering...

Another time I started playing with Dashware to overlay telemetry on the inspire video and surprise surprise, Dashware was playing the 4k video very smoothly, I could jump scenes up and down, no delays, no frame freeze, just wonderful. My conclusion is that the lads at VLC and Dashware can do it very well, Adobe cannot or there are settings that I have not found in CC that allows to edit 4k video. No doubts that the software is at fault here!

Proxy files.
Also are you editing with a 5k screen? otherwise no need for 4k preview renders. as even with a 4k screen you will have toolbar & timelines etc.
Then you can just export at full res.

Note. You can play & edit 4k footage on an iphone & ipad... you dont need these beefed up computers (although it does help.. I run a 5k imac with 4gb graphics & 24gb ram, but I can also edit just fine on my macbook laptop) You just need to tweak you settings.

Use handbrake to transcode the files to MPEG-2, keep the other settings as is. Seems to work like a charm in Premiere CC 2014.
