Choppy playback in CC, suddenly

Yes, yet another mysterious choppy, jerky playback out-of-the-blue issue.
Premiere Pro CC 7.01, Mac, was working relatively fine for a few weeks on a couple projects. Now, on new project, exact same setup and media as before, I get playback that is fine, then after a few moments or a minute, gets choppy, as my CPU becomes increasingly pegged, as if GPU acceleration becomes disabled with time. Cannot edit when it is like that. I give it a rest for a few moments, can play ok for a minute, then CPU and choppiness creaps up again.
Premiere Pro CC 7.0.1
Mac OSx 10.8.2
Nikon D800 and D7000 .mov files, 1920-x1080 23.976fps, High Quality
Sequence: DSLR 1920x1080x23.976fps
Project: Mercury OpenCL GPU (via AMD Radeon 6770m in Macbook Pro.) No change if switch to Software Only.
Premier Pref/Memory: either Optimize for Performance or Memory, and restart. No effect.
Playback Resolution: 1/2. Always worked before.
No other software running. (Time Machine enabled, not backing up. Crashplan paused or service unloaded did not help.)
When CPU pegs, it is kernal_task and Premiere at top of All Processes/%CPU table in Activity Monitor.
Macbook Pro, late 2011, quad-core 2.5 GHz i7, 16GB memory. Apogee Duet2 audio output.
Source files and cache files and preview files on Pegaus Raid on Thunderbolt. NEC monitor on Thunderbolt. Premiere on internal drive.
No complex layers, effects. Just straight video and 2-4 tracks of audio. So little to no Previews rendered. Timeline bar is yellow, which always played fine (via OpenCL.) Rendering Previews of a few minute section does not help.
Happens whether doing multicam sequence or simple cuts.
Cleaned media cache (Premiere/Prefs/Media/clean cache.) No Previews to clean out.
Graphics Switching disabled, so always on Radeon.
Only Changes since it was working -
CC app update (i.e. the menu bar thing, but I usually Quit that anyway.)
Indesign CC, Extension Manager update (but never launched.)
More memory allocated to Crashplan (but if I pause or unload that service no effect. And memory does not seem to be an issue looking at Activity Monitor.)
Checked Files on and rebuilt Thunderbolt raid directory (with DiskWarrior, just as general maintenance.)
Apple Timecapsule firmware updated to 7.6.4.
Maybe Java updated to v7 update 25 during that time.
Thanks,
Vincent

Solved. (Possibly only temporarily - I will report back.)
Unfortunately I was in panic mode so I was not using scientific method to fix my problem – more of a shotgun method.
Major variables here so I’ll try to recap.
#1) I started messing round with Lumetri “SpeedLooks” LUTS for the first time directly in Premiere. I have been using the lumetri looks that are in premiere now – but I have never gone and grabbed a lut from somewhere else – which I did when I imported the SpeedLook luts from the Speedgrade program folder. This was the beginning of the end – whatever happened started slowing everything down and started giving me choppy codec/frame rate issue feeling problems ever forward – even when I would play stripped down clips directly from my camera on the source menu.
#2) I started rolling my nvidia driver back and forward while troubleshooting – I ended up in the forward most current position, but who knows.
#3) As mentioned I uninstalled and reinstalled Adobe Cloud and Premiere in order to get to the newest version. Adobe Cloud was lying to me about my apps being up to date. Don’t believe the lies. Terrible lies. Will this keep happening? Is there even support for the Adobe Creative Cloud app itself? On the latest and greatest (ahem) version of both for now.
#4) I was constantly creating a new project for troubleshooting but this time I decided to save it in a completely new folder way out on my root nowhere near where my video projects have been for the past 9 months. Once I relocated the project and the source files to a new distant location I dragged some footage on the timeline and it worked! Then I loaded it with effects (no LUTS, not that brave) and it worked! I was back to my old self as though my home office was the TARDIS.
So… If it is a weird corrupt file or old cach preview files issue, will these bad vibe files start building up again in this new location and one day out of the blue I’ll suddenly be editing in 1979 on a TRS-80 again? Why did this start happening to my projects to begin with? Did the SpeedLook LUTS create the possibly bad preview/cache files to begin with? Did this happen because I was messing with SpeedLook LUTS inside premiere, with Canon 5D footage on an unbeknownst to me (or Adobe Cloud) old (7.0) version of Premiere thinking I was on the latest version? Dare I try LUTS again now that I'm finally stable?
I’m a paranoid gunshy mess over this.
When it finally worked I literally watched a few clips for a coupla minutes and had to run. I’ll put it through its paces tonight and see if we’re finally back to the future. (But I’ll probably hold off on LUTs until I get some insight/feedback – because I can’t go through this again – I’ll just have to make my contrasty blue and teal magic in 3-Way CoCo until then.

ITunes 7.1 choppy playback issue on Leopard

I upgraded to Leopard today and updated my iTunes to 7.1. Unfortunately after doing so, I could not get any song to playback continuously. Some songs would only start after a few seconds or play for a second. Any guesses?
Thanks,
Sayaka

I've had choppy playback so much I could puke.
One reason seems to be if memory is filling up. See Activity Monitor and if the green part of memory is going away, that's one reason. Seems the only solution is to reboot as quitting all programs doesn't bring back any green and doesn't solve skipping problems.
Another reason is some other activity. If you're scrolling fast or crunching pixels in Photoshop, that could cause skips in the moment. It shouldn't, but it happens to me, and has been happening for a year or two.
But I think this latest release has some problem. Suddenly there's lots of threads talking about it. ANd I have it skipping with 3gigs of free ram free, and only Safari showing a simple page running on it.
The first song after I reboot, plays ok, but then it stutters, like fifty or a hundred periods of silence per song, scattered around randomly, each 0.1 to 1 second long. All songs finish, if you call that finishing, and they seem to take the correct amount of time to finish.
Maddening. iTunes is my stereo now!! will I have to go back to the old CD player?

HD video has choppy playback on timeline

Equipment:
New MacPro 2 X 2.93 GHz 6-Core intel Xeon
12GBs Ram
Nvidia Quadro 4000 2048 MB video card
Software 10.7.2
Video Card: Kona 3 with 9.0.3 driver & 9.01 premier plugin
Videodrive: 7200 RPM 2 TB internal (not the system drive) remaining space about 750 GB
Adobe CS 5.5 software
I just switched from FCP 7 to CS5.5 including a new computer which I perceive is optimized for CS 5.5. In playback my audio is choppy and dropping out some of the time, then if I stop and start the payback it will be fine, or sometimes there is no audio. doesn't seem to be any consistencey in what will happen the next time I start playback. On the timeline is a 1080i ProRes file I finished in FCP 7, then imported the video & audio file to Premier to make a couple of last minute changes. Program is 50 minutes long. I have the sequence setup as Kona 1080i compressed. I imagine I have missed something very basic here, but don't have a clue what it could be. Can anyone point me in the right direction?
Thx...Jim Watt

John,
I don't really think it's applicable in this particular situation. I have just switched to PP for FCP-7. All my FCP 7 shows are mastered in ProRes and this last one of course was too and it's the one I had to make a small change in. I didn't see anything in the post you referred me to that suggests that PP cannot/will not play back proRes material.
At the moment I'm screening DVCPROHD 1080i material and I'm having the same problem with choppy playback/freezes and lost audio in the viewer. I saw a post that came from Walter Biscardi for audio setup and followed that, which did seem to help a little, but the problem still exists. This is what i did...
Audio...set preferences in Premier to "built in output" and also set audio mapping to same, set audio hardware to "built in output" with caches at 1024
set computer preferences audio output to Kona card...
So I think this is some sort of setup that I have missed since I get identical problem with ProRes and DVCPROHD. Any other sugestions will be most appreciated. I'll give AJA a call tomorrow if I can't find a fix on the forum.
thx...jw

What configuration of the new macbook pro do I need to run FCS 3 without choppy playback.

Yep, just wondering what configuration of the new macbook pro do I need to run FCS 3 without choppy playback or lagging. I'm thinking about the 7200rpm, 2.2ghz, antiglare, 4gb ram, with 1gb GPU graphics card configuration

Nothing wrong with the computer. Playback is dependent on the media and the drives.

Premiere choppy playback after update

Greetings,
I'm having a rather bizarre issue which has just came about recently.
I've been running PPro CC successfully for six months without issue. After the most recent update to 7.2.2 I'm having choppy playback both in the source and program monitors. I'm editing mostly AVCHD from a Panasonic HMC80 camera. The choppy playback occurs regardless of resolution or frame rate. I even tried a standard DV file and that too is playing back not smooth. Changing the playback resolution to 1/2, 1/4 etc.. makes no difference. Changing from Mercury software to hardware makes no difference. I tried creating a new project as well as clearing cache files, previews, etc.. and still have the problem. As a last effort, I re-installed my OS, and re-installed Creative Cloud and Premiere. The issue is still present. My hardware cannot be the issue as I've been editing successfully before. Nothing has changed except for the Premiere update. I've read elsewhere that others are experiencing the same issue. Any thoughts?

Im having the same problem. Didnt show up until after the 7.2 update.
Major lag on one specific spot in the timeline, and muting all tracks makes no difference on the lag.
I cleaned my project file, caches, downgraded playback resolution, tried the mercury playback function. Nothing. Now the choppiness seems to bleed into the rest of the project until it is all so slow and unplayable. I'm having a harder time finishing this project as time goes on.

Choppy Playback when using the PLAYBACK feature in preferences

I've been running into an issue since the PPro CC 7.1 update in October where Premiere will play footage just fine until you tell it to send a signal out to another monitor. Before hand everyhting played fine in the Program and Playback Monitors. Now whenever switched on it plays back choppy constantly. Doesn't matter the footage format.
To further explain -- I have a 3 monitor setup 2 for editing and a thrid for preview playback. All of this runs via my Retina MacBook Pro and has worked fine since PPro 6.0. Never had any slowdown and its been one of my favorite features in PPro.
So when this update came around I ran into the playback issues mentioned above. So I just keep playback switched off and just leave the third monitor barren... figuring it was a bug (?) I waited and saw a few updates, but nothing that fixed said problem. Though with each update and bug fix I've eagerly gone through the same exercise of trying out this feature once more. Again, nothing has changed... However I found out this evening, that when using my three monitors and suffering through the playback, that I can tell monitor to toggle to full screen and instantly my playback monitor has corrected itself and the two play in perfect sync (quick note the program monitor is choppy when not in full screen mode and trying to playback with the third monitor). I can toggle on and off during this playback and when on its fine, the moment its off, its choppy again. Absolutely bizzare. And to some extent makes my playback monitor somewhat useful agian... albeit in a very tedious fashion.
The point is, I'm at my wits end again here. I've seen plenty of choppy playback post, but nothing quite like this. I've tried to clearing caches, and preferences, even did a unistall/reistall tongiht... and I'm coming up with the same issues in the exact same places. But ultimately I am no closer to finding a proper solution to this particular playback issue. Aside from doing a clean install of the OS and all my software, though I'm not sure its worth it just yet. Even if its my last resort.
Has anyone run across playback as bizzare as this? Did you find a solution? Is there a post I've missed? - Thanks

Choppy playback/rendering for one camera in a multicam sequence

Any help is appreciated with this weird, specific problem...
I have a sequence (let's call it "MAIN") which contains many separate multicam sequences (let's call them "M1" through "M5"). Each of these multicam sequences is made up of footage from two cameras, a Canon 5D Mark III and a Canon C100. All footage in M1-5 was shot sequentially, and neither camera changed settings, although the cameras recorded with different settings from each other. The 5DIII recorded at 1080p 23.976fps. The C100 at 1080i 60Hz. This footage makes up all the assets in my project panel and they have no special media interpretation.
Here's the problem. Everything looks/plays fine until I get to M3 in my MAIN sequence. When I switch to camera 2 (the 5DIII), the playback in the program monitor looks about half the framerate of the original footage and all of my other sequences. Camera 1 plays smoothly. Camera 2 in any of the other multicam sequences plays smoothly (while in MAIN). When I open up M3 in the timeline, it plays smoothly. When I open up the original video in the source window, it plays smoothly. Everything plays smoothly but camera 2 in M3 (in MAIN) in the program monitor.
I rendered a clip of MAIN that has M3 cam 1, to cam 2, back to cam 1. Camera 1 is smooth, while camera 2 plays back at about half frame rate and looks interlaced. So this is a real problem and not just some display issue.
The interlaced look of the render made me think there's some sequence settings that were off, whether they were in MAIN or M1-M5. However, the sequence settings of M1-M5 are all identical, and the sequence settings of MAIN are not affecting any of the other multicam sequences.
I tried restarting my computer and deleting my cache. No dice.

Addendum: After playing around with sequence settings a bit, but after resetting them to be all as they were, now M2 is giving choppy playback on camera 1, while camera 2 plays smoothly. What in the world is going on here?

The LEDs were reflecting on the book that the GoPro was on but I got it to work with a garbage matte using a frame grab with the lights off and including the book. It worked a treat! But I am going to remember the dark grey matte thing; less is more and all that. Thank you for your input, much appreciated. Ooh and as for multicam syncing I just nested the composite shot and used that as a single camera source.

Choppy playback with mxf files...

Hello. I have been working with Premiere Pro CS3 for quite sometime until just recently. Then last week I installed Windows 7, then Premiere Pro CS5.5 along with various updates. I usually work with DVCProHD (Panasonic), 720p, 60p. I just started working on a new project and playback is very choppy, whether the footage is rendered or not. Everything else works fine. My computer (purchased in 2008) has Dual Intel Xeon 5150 (10.64 Ghz total), 4GB DDR2-667 FBDIMM RAM (4x1GB), and an ATI FireGL V3350 256MB PCIe Video Card. I am using a dual monitor set up as I used to do with Premiere Pro CS3 and Windows XP (with no problem before I went to CS5.5). I checked the settings for the Mecury Playback and it seems to show that it is selected but also grayed out (can't be changed to anything else). Anyone have thoughts on why the choppy playback? Even Premiere 6.0 never gave me choppy playback like this. Thanks in advance.

> Exactly how much RAM is Premiere Pro CS5.5 able to use at maximum?
All of it. That's one of the reasons that we ported Premiere Pro to be 64-bit.
Are all files of all types giving you choppy playback, or just some? If it's only some files, then tell us as much as you can about those files.

Why am I getting such choppy playback?

Long time reader, first time poster, I'll make this short and sweet. Here are my specs:
Imac 27"
3.4 GHz Intel Core i7
24 GB 1600 MHz DDR3
NVIDIA GeForce GTX 680MX 2048 MB
1TB internal Fusion drive SSD
I am working in a fairly big (1TB footage) 4k mixed with 2k project. It's a 3 simultaneous camera shoot, so I need to multi-cam. I have two external WD Caviar Black 7200rpm drives. I also have a Lacie 1TB Thunderbolt drive available.
Because the final output will be 1080, but possibly 2k in the future, I decided to import all the RED footage natively (as opposed to transcoding to prores 1080). All my sequences are 1920x1080, with multi-cam nesting in 1080 as well. Ram is allocated to 20GB Premiere, 4GB other.
No matter what I've tried, I always get choppy playback in the project...especially with multi-cam activated, even at setting my resolution to 1/4. What I've tried:
All Media on WD 01 drive...Project, Cache, Preview, Scatch on WD 02 drive...Internal SSD for OS and Apps: Terrible performance
All media split between WD 01 and WD 02...Cache, OS and Apps on Internal SSD...project, preview, scratch on WD 01. I also tried the same thing but with the project, preview, and scratch on my Lacie 1TB Thunderbolt and internal SSD: Slightly better than all media on 01 drive.
At this point I feel like I've tried every variation of where the MEDIA, Cache, project, and Scratch/preview files go but nothing seems to give me smooth playback consistently. I'll have brief periods where it's very smooth, but then choppy soon after. I'd understand if I were trying to edit in 2k or 4k, but all my timelines and nests are 1080. Even if I pre-render the sequence, it barely helps. Is it possible I need more RAM, a better GFX card, better external drives? Help?!
EDIT: Premiere 2014 updated to latest version. No big apps running aside from Premiere. All my drives have at least or close to 50% space available.

Recommend you take a look for disc layout & such over at the Tweaker's Page ...
Tweaker's Page ...
http://ppbm7.com/index.php/tweakers-page
Basically they recommend just the program file on the system/OS disc ... and then putting things on other drives as per the needs of the "asset" ... some need very fast connects, a couple only mostly fast connections.
Footage is mostly a one-way read-only operation, and export out is mostly a read operation, so those can at need be on somewhat slower connections as long as they aren't on the SAME drive over a slower connection. Such as say one of the PNY 128Gb high-speed USB3 flash-drives into a USG3.0 external port on your computer. I've adapted this from one of the other users, and it works fairly well for my 1080p footage. I export to one of several drives I've got in external boxes connected via USB. It's adequate, though not blazing.
Everything else ... project files, database, previews, cache ... there's a TON of read/write work going on constantly during playback with these. So 7200 or faster "standard" drives or SSD drives, connected internally via SATA-II or better, or external via eSATA-II and Thunderbolt connections are needed. None of the Firewire nor USB2/3 connections available have near adequate sustained read/write speeds to work in the massive testing they've done at the above mentioned site. The "burst" speeds claimed by manufacturers are achieved on the absolute most ideal set-up with the um ... right size? ... of data packets to get the best numbers. They aren't usable numbers for heavy and constant read/write demands like the Adobe DVA's through at the machine.
Remember ... during playback ... PrPro "reads" the source footage including when to jump in & out of every clip, throws in all your instructions for editing, color changes, transistions, effects, EVERYTHING ... and on-the-fly builds the image you see in the playback monitor. It doesn't make something for it to just 'read' from disc, it does this on the fly. Even when you make previews for a section of a timeline, any change you make ... those previews are outdated.
Which is why we all need machines that both have pretty solid hardware off the mobo, AND plenty of high-speed disc connections. Best case is say a 4/5 disc array of 2Tb discs in RAID 0 or 5 for the project files, d-base, cache, & previews ... and that can maybe even have media (original footage) on it.

More choppy playback issues

None of the previous discussions have provided a solution, even though I followed all of their advice.
I have a new project, started on CC2014 V8.2.0
OS X Yosemite 10.10.2
Macbook Pro I7 16 GB 1600 MHz DDR3
NVIDIA GeForce GT 650M 1024 MB
Working on 1920X1080 sequence, *no* effects, absolutely none
footage and project file on external thunderbolt 2Gb Western Digital HD
After playing the sequence for a few seconds, it starts to 'hang' and 'stutter' and will not play smoothly.
I have:
clicked "Maximum Render Quality" in sequence settings
unchecked "Composite in Linear Color" (although it keeps checking itself back on)
cleared all the caches, both within Premier, and using "WhatSize" app
restarted, rebooted, re-everythinged
Still will not play smoothly. Any suggestions? Besides going back to FCX that is....

1. two weeks ago I completed a project with footage from the same camera, on the same computer, with the same drivers, and had no problem, so I have trouble believing it's the Nvidia driver.
2. I did turn off, then on, then off, then on, etc. the GPU acceleration, no effect
3. Again, the same project I completed two weeks ago was from the same external HD (You're right, 2Tb, sorry) and again no problem.
4. I upgraded to Yosemite just a couple of weeks after it came out, long enough ago that I can't remember exactly when, but again have completed many projects since without this problem.
5. I can play the mp4 files on any other program smoothly, VLC, Quicktime, RealPlayer, etc. so it's not the footage.
I went through the forums and tried every suggestion I found, and it seems like there were indeed a lot of issues with choppy playback, and a lot of suggestions on how to fix it. None of the steps put forward have helped, and according to at least one of the forums I've read, that person was unable to find a workable solution. Starting from scratch seems pointless, since I just started this project fresh a few days ago.
I really feel like in the latest update from Adobe something else got screwed up and I have no choice but to live with it until they decide to acknowledge it and fix it.

Choppy playback of AVCHD footage. 1920 x 1080 60p. Imported as optimized media.

So I have some stuff shot on different days, same card, same camera, same settings. 1920 x 1080 AVCHD 60fps progressive, imported as optimized media. I know my computer and external drive are able to handle this kind of footage. What is puzzling is that some clips with the same specs, play back very choppy (like unrendered media) and others play back wonderful. What gives, I must be missing something obvious. Why would some clips play ok and others really badly? I have double checked that everything (codec, frame rate, optimized vs. proxy) is the same by viewing stats in the events browser. Dropping these clips into the timeline does not show they need rendering, but if I output the clip as a master file, it plays fine. I have clips in other events that play great, with the same specs. I am at a real loss. thanks gentlemen.

Sorry, but I can't think of anything during import that would introduce errors that would cause choppy playback. A momemttary loss of connection would be a problem but would typically corrupt the file and it most likely not play at all.
If you hadn't said that some clips played (or previewed) perfectly smoothly, I'd suspect a hardware problem.
Maybe someone else will have some better ideas.

Choppy Playback - Video Card? Settings?

I am experiencing Choppy playback, I am using HD video recorded on a Flip Mino and a iPhone 4.
After getting numerous "dropped frames" warnings, I have transcoded my media to proxy video and still get choppy playback and dropped frame warnings (I have elected to turn off the warnings).
I have a late 2009 MacBook Pro with a NVIDIA GeForce 9400M with 256MB VRAM. 4GB of RAM.
I am selecting to use Proxy Video in my Preferences.
I use an external G Drive via FireWire. I realized I am on the low end of video card requirements, but should playback be this bad?
I have to export to a MOV file to actually see playback without the frame drops.
Is this unusual, or am I limited by my video card?

That drive will work best for video editing compressed HD with the eSATA interface. FW800 would also give you a few HD streams. But, if you use the USB2 or FW400 interface, you're not going to be much better off than using your single drive. That's called a "bottleneck."
Here's what you need to find out:
1. Estimate what the data-rate is for the footage you want to use. There are "data-rate calculators" all over the internet. Use Google.
2. Mulitply that data rate times the number of layers you want to play simultaneously in real-time.
3. Install a drive AND interface combiniation that exceeds the "Sustained Data Transfer Rate" for the number you came up with in #2.
Then, if you drop frames, it's not because of your drive (array); it's due to puny CPU or some other factor.
Some codecs strain the CPU more than others. Long-GOP codecs require more decoding to play back than intraframe codecs. Most DSLR footage is Long-GOP, and some flavors of it take 100% of all eight of the 3GHz cores in my MacPro to play back one stream. 2 or 3 is out of the question, no matter how fast my RAID is.
So, it may be that drive speed isn't your problem... you may have just maxed out your CPU's ability to decode that many streams of video in real-time.
But, if you do the math I just suggested, you can determine whether your drive is the issue.

Choppy Playback of Blackmagic ProRes in Premiere CC

Hi there,
I'm editing a friend's short film, shot on the Blackmagic Cinema to ProRes files. In standalone Quicktime, outside of Premiere, the files play seamlessly, but in the Premiere CC project, Source and Program Monitors, the clips are choppy/frame-dropping, even at 1/4 resolution.
I've edited countless shorts and features on this system - Canon 5D, 7D, Scarlet, C300 - and I've never experienced choppy playback. Any advice on how to nix this? Quicktime is fully updated, and, like I said, the files play perfectly in actual Quicktime.
Thanks!

Hi SDCone,

Choppy playback after burning data dvd in toast

Hi Ive just finished burning a copy of various short clips which I exported as a quicktime files from FCP onto my desktop then saved them as quicktime mov. through QT player which was successful enough.I then burned a copy of this QT movie in toast as a data dvd compatible for Mac & PC viewing.When I played the dvd in QT 7.4.5 the playback was choppy but the sound was fine. I then played the same disc on my G5 desktop running panther and QT 7.4.1 and it was absolutely fine.Is this process rather a roundabout way of doing things ? and what could be causing this choppy playback on my laptop?

Data DVD's and regular movie DVD are not read in the same way. A regular movie that is being read by your DVD player app is being stream too...and the player is set up to read from a DVD that way.
On the other hand a data DVD the data is just setting there...The DVD player can't send the video to Quicktime fast enough to play smoothly. That's why you need to copy the data DVD to the hard drive.
It would be if you had a 1gig image on a DVD and tried to edit it with Photoshop from the DVD. Photoshop would constantly bog down trying to read from the DVD while editing the image. Same if you had video files on a DVD tried and to it them from a editing app. The editing app not getting the data fast enough making editing very slow. Sometimes the program that's trying to read the from the DVD will freeze or crash. Best to copy the data from the DVD to the hard drive.

Choppy playback after upgrading hardware

I've recently upgraded from a phenom 965 and 7gb 1333 gb ram, to an i5-2500k with 16gb 1600mhz. Otherwise everything is the same, i just reinstalled windows and premiere pro after the upgrade. After the upgrade this error, or annoyance, occured. Here's all the specifics:
-Premiere pro CS5.5.2 v/latest updates
-Windows 7 pro (fresh install v/important updates)
-h.264 in mp4-container
-no error messages
-very choppy playback after "jogging". When theres a lot of movement, the picture becomes very "stuttery" and "pixelated" in that area.
-no extra codecs or similar is installed.
- hardware:
-nvidia gtx 560 v/latest drivers
-i5 2500k @ 4,6Ghz
-16Gb 1600mhz xmp ram
-7200rpm 500gb source hdd
-5200rpm 120gb scratch disk
-Agility 120gb ssd OS and programs
I have tried using 1/4 playback, using ssd as scratch disk, installing and uninstalling extra codecs but none of it made any difference. The cpu or ram never exceeds 50% capacity when the problems occur.

But wouldnt the cpu reach 100% capacity before it starts being the bottleneck?
Only if all the other components supply data fast enough that the CPU can run flat out. If the CPU has to wait for other components to catch up, CPU load will be less than 100%.
If you race alone on a track and there are no other contestants (components) in the race, you can go flat out at 100% of the speed, but if the track is filled with many other contestants (components) from a local old-age house, your speed will drop significantly.

Choppy playback in CC, suddenly
