1080 30 video playback stutters on 2011 15inch 2.3 ghz i7 8GB Ram

When playing back 1080 30fps video the clips stutter and drop frames full screen in Quicktime. The MBP is a 2011 15inch 2.3 GHz i7 with 8GB RAM, AMD Radeon HD 6750 and Intel HD Graphics 300.
I would think that a machine of this sophistication would play back 1080 30 full screen with ease.
Does anyone have suggestions on how to improve full screen playback?

These are .mp4 1080p 30 files from GoPro HD2 cameras. Average file size is 2GB. The problem is not consistent...but intermitent. There may be something that I don't understand about memory usage/reservation during long review sessions.

Audio and video playback stuttering...sometimes

I'm having issues with audio and video playback stuttering at times in several applications. It's the same kind of skipping or stuttering in each application, whether it's iTunes (version 10) or YouTube or Netflix (Safari). I can also hear it when I'm just adjusting the volume via the keyboard, the "clicks" stutter.
I'm not running anything other than iTunes and Safari at once, the iMac has 2 gbs of RAM, it's running Snow Leopard. It also will work sometimes for a while. I just can't figure out why it will work sometimes and not others. Any ideas about what the cause may be? Quicktime X have anything to do with it?

Quicktime wouldn't work either.
Until you max out your ram, you are pretty much stuck between a rock and a hard place. In the meantime, make sure you have the latest versions of

I'm noticing that in general it's running extremely slowly now, even with only the browser running.

I have a Macbook Pro june 2011... I have 8GB ram but I only have 256mb VRAM... I've read some other questions about this and I realized... Why do I not have 560mb of VRAM since I have 8GB of RAM? Is there any way to get more VRAM to play games on steam?

I have a Macbook Pro june 2011... I have 8GB ram but I only have 256mb VRAM...
I've read some other questions about this and I realized... Why do I not have 560mb of VRAM since I have 8GB of RAM?
Is there any way to get more VRAM to play games on steam?
I've learned by reading other topics that I can't upgrade my graphics card on my Macbook Pro because it's soldered into the motherboard or somthing like that, but please tell me if there is any way to get more video ram by chaning some setting or upgrading something else. I'd also like to know why I only have 256MB of VRAM when I have 8GB of RAM, since I have 8GB of RAM I thought I was supposed to have 560mb of VRAM...
So the two questions are...
Is there any way to upgrade my VRAM, so that I can play games on steam?
Why do I only have 256MB VRAM when I have 8GB total RAM?
Other Info:
I have a quad core i7 Processor.
My graphcics card is the AMD Radeon HD 6490M.
I am also trying to play games on my BOOTCAMPed side of my mac, or my Windows 7 Professional side.
THANK YOU SO MUCH IF YOU CAN REPLY,
Dylan

The only two items that a user can change on a MBP are the RAM and HDD (Retinas not included). You have what the unit came with and the only way you will be able to change that is to purchase a MBP with superior graphics
If you are very much into gaming, the I suggest A PC. They are far superior for that type of application to a MBP.

Apple TV video playback stutters - even with SD

Hi,
i don't know what i am doing wrong, but i have some serious video playback troubles with my new atv:
All files start to play fine, but somehow - like every few seconds - the movie seems to stuck for a very short time - just an eyeblink. it looks quite the same when you play a HD Movie on a computer and the CPU is not really capable of playing back this files...
it doesn't matter if the video files are on the internal drive or streamed over wlan - same problem...
i'll tried lots of different software for the video converting: visual hub, handbrake, quicktime pro... always the same problem...
The strange thing is - all apple trailer movies playback just fine!!! even in HD - smooth as butter...
Please help me!
Thanks - Matt
my setup:
Apple TV 2.3:
720p - 60Hz
TV:
Samsung Le-40a557p2 LCD-TV
Sound via optical cable from aTV:
Sony DAV-IS 50

Assuming you're using conservative video encoding and not pushing things to the limit, I'd say something is probably amiss with the AppleTV.
If you were just streaming I'd look at the network first of all, but you say it hapens with synced files too.
Assuming you've pulled the plug and rebooted at some stage, I think I'd do a system restore (which will delete all media so make sure any purchases are transferred first), and if it was still an issue, then I'd get the new AppleTV replaced.
Occasional glitches happen but they shouldn't happen all the time.

Browser to flash HD Video playback stutters on Atom-ION based PC

When ever I try to play video in hd, the video playback will stutter. Meanwhile Xbox Media Center can all three videos just fine using the appropriate free video plug-in.
Can the Adobe Flash Player be fixed and optimized to play videos with smooth playback, on the Atom-ION PCs.

Can you say even more about what it is you want to do? I mean, what will the application do, not what are the technical aspects of how it will work?
For a point of comparison, look at this thing I did:
http://www.cartoonnetwork.com/mixit/
If you try out the Make page, both the template ones and the from scratch one, as well as the View page to see the playback unit in action. Is what you're going to do anything like that?
I have tried the playback part of this as a mobile app, and it so very nearly works ok! Amongst the many problems are that the overall data rate needed is quite high, and mobile devices aren't as consistant or high bandwidth as desktops, the external swfs often need code in them, so that rules out iOS, and to do the layering involved rules out H.264.
At some future time there will hopefully be StageVideo that can use H.264, but I don't know when that will be, or whether it will be responsive enough (FLV is much faster to connect to and play than H.264).
Incidentally, even in the Objective-C world you can't lay things on top of the standard iOS H.264 player. To do that you have to use the AV Foundation class, so it's fairly low level programming. Using FLV in Flash is a lot easier!

How many HD 1080p Videos should the New MacBookPro Retina Display (2.6GHz i7, 8GB Ram, Flash Memory) should run Flowlessly/Smoothly??

Dears at Mac Support,
I am a Visual Artist, and I use my MacBook Pro for live Visual/Video Mixing and effects. Since I moved to this new club, i need to run all my Videos on HD 1080p Format. I already had the Latest MacBook Pro (2.3GHz i7, 8GB RAM) with the Stock HDD (5,700 RPM), and it performs beautifully, The only issue was Running more than 1 HD 1080p Videos, where you can feel the slowing down of the Videos. The Solution is moving to SSD Drive where I can run 2 or more HD 1080p Videos Simultaneously (Over Layered).
Instead of investing in an SSD, i preferred buying the new MacBook Pro Retina Display (2.6GHz i7,8GB Ram, 512GB Flash memory). Everything about the new MacBook Pro should support my work and give me a better Performance. Unfortunately, I am not able to run ONLY 2 HD 1080 Videos to gather! The result is being Breakdance style video, like it's cutting and continuing the videos. Compared to my Old MacBook Pro (2.3GHz i7, 8GB RAM), on the old one the Video slows Down but does not Leg or Cut
Is there a Solution for this issue? Or i simply did the Most useless investment of my life?
PS: Both Running on OSX 10.7.4, and both are running on the Video Codecs and Visual Performance Software (Modul8 2.6.4)
More Details: Video format is .MOV (Photo JPEG)
If there is any more details you would need, please do let me know.

A faster hard drive connection is available through your Thunderbolt port. See what you can connect via Sonnet's adapter:
http://www.sonnettech.com/product/echoexpresscard34thunderbolt.html
An eSATA or Thunderbolt hard drive would probably be at least faster than the internal drive, and an external SSD may be cheaper than an internal for your notebook, and even faster.

Video playback stutters in small viewer

When I start playing an event or project in the small viewer window in iMovie 11 (at the top right of the screen), the video plays for a few seconds then stops, then plays some more, and pauses again. It keeps stuttering during playback. The strange this is, when I play back in full screen mode (command-G), it plays back smoothly without interruption. The video source is a DV file. It used to play back just fine in the small viewer, but then something happened. My iMac is a quad core and plenty fast enough. Any ideas?

easy answer first: your audio properties do not
match your sequence audio properties, hence the need
to render. if you're working with mini dv, the audio
should be sampled at 16 bit 48k but as you've a
problem, i'll surmise that you're not using the easy
setup to capture and set up your project.
I did the capture awhile ago. I don't think I did anything unusual, but I can't guarantee I didn't. See my answer above to Jim Cookman. If I did, I'm not seeing what it was - nor, more importantly, how to resolve it. Would batch-processing the clips to reconvert the sound in some way be appropriate? If so, any ideas what I would convert to?
it would be helpful if you would go into more detail
about your set up. none of us can look over your
shoulder. where's this media stored? system drive
or another hard drive? if another hard drive, is
that an internal or an external hard drive? if it's
external, how do you have it connected; firewire or
usb? if it's firewire, what else shares the firewire
bus? if it's usb, stop using usb!
External Firewire 400 drive - 4th and last on a chain.
what have you done to your computer recently?
I keep it upgraded with normal Software Update changes. Got the new version of FCP (5.1) a couple months back and it's upgraded to 5.1.4. I don't think I've done anything else out of the ordinary.
Of course I don't want to rule out anything - but the clips play back fine in the Canvas and in QT, so I'm skeptical it would be a hardware issue.
Thanks - I appreciate your interest and help.

HELP - Interlaced video playback stuttering!!

Hi all,
I'm having problems with Quicktime playback of Interlaced video. For testing purposes, I'm playing back a PAL 20 second h.264 clip on a secondary display attached to my MacBookPro with the Apple DVI-S-Video adaptor (set to 720x576 interlaced PAL 50Hz).
When I play the clip, it stutters/flickers (almost like the fields are inverted?).. If I pause then play the movie repeatedly (i.e : stop/start with the spacebar) the problem seems to rectify itself for a few minutes and everything runs smoothly, then it happens again, until I pause/play again.
I'm on Leopard with the latest updates.. I desperately need to find a fix for this ASAP as I have a tradeshow install in a couple of days time.. Any help would me most appreciated.
Thx

I've never tried how well interlaced material transfers from the Mac directly to an interlaced TV...
But I do know that feeding interlaced .dv from iMovie (in passthrough-to-camcorder mode) via FW a a TV is fine. Or burn it to avideo-DVD via iDVD and use a standalone DVD player to present it.
Maybe H.264 sometimes loses its field sync? Could you use brute force and deinterlace it and live with the less smooth movements of progressive video?

HD (High Definition) Video playback stutters and there is lag

When I play HD content on my Macbook the video stutters alot, although the audio is fine. Thus I basically cannot watch HD movies.
Any ideas how to solve this. I've closed all other programs when I'm playing the movie, and I'm not running off the battery.

YouTube playback is going to be limited by your internet connection speed more than anything else, so I wouldn't use that as any test for HD playback. Besides, YouTube is running on Adobe's Flash technology which is notorious for its poor performance.
You say you are having problems even with .m4v files but where did those files come from? Can you try the Disney video clip ("Earth" HD 1080p preview) I mentioned earlier since I know that it works well on my MacBook. If you are playing files that have been encoded by just any user with just any third-party tool then I'm not certain that you can use those as a test either (since some files that you will find on the internet will be encoded, well, just badly).
As for Spaces and Exposé the relative performance with those tools can be affected by a lot of factors, some completely "normal" (i.e. I wouldn't expect their operation to always be smooth).
Have you tried running with _all_ peripherals disconnected and with networking/WiFi/Bluetooth disabled?
Have you confirmed that you don't have a memory or disk "hog" that is running in the background? How about checking for any high-CPU loads that are running in the background? Have you used Apple's Activity Monitor in the show "All Processes" mode (with a sort on % CPU)?
Here is what I see in Activity Monitor while viewing the "Earth" HD preview in the QuickTime Player on my 2.0GHz MacBook (with only the QuickTime Player and Activity Monitor applications running):
Activity Monitor: All Processes Sorted by % CPU
QuickTime Player     27.6 (% CPU)
WindowServer            6.2
Activity Monitor         5.9
pmTool                      2.9
kernel_task                 1.9
Finder                         0.0
<and many more all running at 0.0>
These numbers (% CPU) will fluctuate but generally you should only see QuickTime Player, WindowServer, and Activity Monitor running at more than a few percent. You may see _very_ brief spikes from some other processes but these should be rare and very short. In particular for the "Earth" HD 1080p preview you should see the QuickTime Player at the top of the list and generally running in the mid to upper twenty percent range (% CPU).
Here is the System Memory data from Activity Monitor (this was taken immediately after a restart of my MacBook but while playing the HD video in QuickTime Player):
Free 1.3GB  (this will vary with the amount of installed memory, my MacBook has 2GB SDRAM)
Wired: 162MB
Active: 255MB
Inactive: 9MB
Used: 426MB
VM Size: 30GB
Page ins: 85MB
Page outs: 0 bytes
Swap used: 0 bytes
Once again, these numbers will vary so don't expect an exact match to what you will see. However, the only figures that I would think would vary by much are the VM Size and the Free memory if you have more than 2GB installed in your MacBook. This also assumes that you've done a restart immediately before you play the video in the QuickTime Player. By the way, have you installed any third-party memory in your MacBook? You seem to have 4GB, is that all Apple installed or did you upgrade it yourself?
Under Activity Monitor's Disk Activity you will see a lot of variation (up and down in the Data read/sec) while the movie is playing but generally you should stay in the low, single-digit MB/sec range (e.g. 2.1MB/sec). The range will go from only a few hundred KB/sec to maybe (rarely) up to something like 6MB/sec. However, Data write/sec should be very low on average (actually around zero).
Next download the AJA System Test application and check your hard drive performance (it's a free download from http://www.aja.com/products/software/ ). When running the AJA benchmark you should be seeing transfer rates that are consistently and steadily in the 40 to 50MB/sec range. AJA System Test allows you to watch the transfer rates in a graph so you can look for unexpected "stalls" in the hard disk access and transfer rates. To test for long period transfers increase the File Size option to something over 1GB. You may want to run this test several times while you have nothing else running on your MacBook. You may see a few brief but significant drops in the I/O Transactions rate but generally both the read and write rates should stay quite close to 50MB/s. If you don't see numbers like I've noted above then you may have a hard drive issue (either hardware or software or some background task that is using your disk even when you don't know it).
After all the above checks if you are still seeing obvious stutters while playing the "Earth" HD preview then I suspect that you either have a hardware problem or have some third-party software installed that is causing playback problems. This assumes, however, that you have tried all of the troubleshooting steps that I've outlined before (such as disconnecting all peripherals and turning off WiFi and Bluetooth).

Hard disk for second-hand 13" early-2011 mbp (2.7 hz i7, 8gb ram)

i might be able to get hold of a cheap, second-hand 13" early-2011 macbook pro, specs are 2.7 ghz core i7 with 8 gb ram. it will not come with a hard disk.
i'm thinking of asking a friend to help install the harddrive but as far as i know he's not a mac user. do you know if this mbp can accept any generic hard disk? are there any restrictions as to what can be used and is there anything he should be aware of?

First, you're going to need a hard drive. Currently, for the MBP, you can choose from three types of drives. SATA drives (for the current MBP, SATA-3) a reliable and come in two speeds, 5400 or 7200RPM. SSDs are solid state drives, and can be fast and reliable. Hybrid drives are a cross between the two types.
Several sites will provide you with video tutorials on installing the drive. OWC has a variety of helper tutorials.
Once you get the drive, you're going to have to install the operating system. Currently, the OS is downloaded via internet, but you can still find copies of an older OS on eBay that comes on DVDs.
Feel free to ask more questions!

Why is video playback continually stuttering after the Mountain Lion 10.8.2 update?

Since updating to Mountain Lion 10.8.2 video playback in iTunes and QuickTime is unwatchable. The video stutters constantly then plays catch up to the sound. I'm running a 2011 Mac Mini i5 2.3 GHz and 8 Gb of RAM. Anyone know how to roll back the update to a working version of Mountain Lion?

Hello, you'd have to reinstall 10.8.0 or 10.8.1, but...
See if the Disk is issuing any S.M.A.R.T errors in Disk Utility...
http://support.apple.com/kb/PH7029
Open Activity Monitor in Applications>Utilities, select All Processes & sort on CPU%, any indications there?
How much RAM & free space do you have also, click on the Memory & Disk Usage Tabs.
Open Console in Utilities & see if there are any clues or repeating messages when this happens.
In the Memory tab of Activity Monitor, are there a lot of Pageouts?
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.
Check the System Preferences>Other Row, for 3rd party Pref Panes.
Also look in these if they exist, some are invisible...

Thank you again andyBall_uk.
I have successfully run Apple Hardware Test and it returned the error code...
4SNS/1/40000001:VPOR
A Google search reveals that this is a sensor error. The "V" of VPOR indicates a voltage sensor and the "P" indicates the sensor is on the Power bus. However don't yet know what the "OR" refers to.
I have had a non operative optical disk drive for a year or more but the fault with the video only developed in the last week or two. Could the "O" in VPOR refer to the Optical drive?
By the way, I got the impression from the instructions on running the Apple Hardware Test that I had to use the internal dvd drive to run the APT program from the install disk. But this turned out to be not the case. Just put install disk ito an external drive plugged into the usb ports and use system preferences to set this drive as the start up disk.

Online video playback is severally laggy/choppy on my macbook pro 2011?

hey guys, got a bit of an issue here. I've been noticing some SEVERE lagging issues whilst viewing online (streaming) video, from various sites, including, novamov, youtube, and others. the videos rarely stop to buffer as i have a fast connection, but yet they still seem to lag wildly. what i mean by this, is the sound will continue as normal, the the picture will freeze sometimes for a good 5 seconds or so before resuming, this is happening increasingly more and more..
i am running Mac OSX Lion (latest Update) on my:
MacBook Pro
17-inch, Early 2011
Processor 2.3 GHz Intel Core i7
Memory 8 GB 1333 MHz DDR3
Graphics Intel HD Graphics 3000 512 MB
Software Mac OS X Lion 10.7.3 (11D50b)
If it helps my hard drive space is:
Macintosh HD
Capacity: 664 GB
Available: 179.79 GB
The browser i am using is the latest version of Safari, although i have tried firefox and chrome and i experience the same issue.
I have Sophos anti-virus installed and run regular scans on my system (all clear)
i really can't think of anything else which could be causing an issue here. I haven't installed any additional software for a while, not in the time frame since the error started to occur.
I am quite surprised to be experiencing such issues as lagging on something as simple as a youtube video when my £3000+ computer handles heavy applications such as Final cut pro and Photoshop with ease...
i MUST be missing something here,
I really would appreciate any help i can get here.
thankyou very much for your time

Hey Carolyn,
Worked a treat, de-jaggy video for first time in months!!! Only point of clarification, I manually deleted the Flash plug-in before I uninstalled Flash. Don't know if this was why it worked for me rather than others but hey ...

Hi Ben...

Try troubleshooting the Flash plugin required for most YouTube video.
Quit all open browsers. I'm using Safari as a test.
Open System Preferences > Flash Player then select the Storage tab. Click: Delete All
Now uninstall the Flash plugin then reinstall new > Troubleshoot Flash Player | Mac OS
Make sure and uninstall the current plugin first.
Then launch Safari. From your Safari menu bar click Safari > Empty Cache
Now try a video.
BTW... if you have the ClickToFlash extension installed, that can prevent Flash based video from streaming. It can also be installed as a plugin in /Library/Internet-Plug-Ins.
And check to see if Safari is running in 32 bit mode. Right or control click the Safari icon in your Applications folder then click Get Info. If the box next to: Open in 32 bit mode is selected, deselect, quit then relaunch Safari.

2011 iMac 27" Bootcamp AMD 6970M screen tearing/vertical sync issues on 2D Video Playback

Hi Everyone,
I am actually running an Radeon 6970M embedded graphics processor on an iMac 27" 2011 model running bootcamp and windows 7 64-bit.
I am having the same issues with the drivers Apple includes on the bootcamp DVD, as I am having with the drivers download from the AMD website dated 4/13/2012 with the filename:
8.96-120315a-135852C-EDG_Direct
The issue I believe is with vertical sync on any 2d video playback or even in normal desktop actions. I see screen tearing visible in normal Windows 7 operations (click and draw a rectangle on the desktop and I see screen tearing).
When I watch flash videos in google chrome or in internet explorer (ie: Hulu Plus, or netflix) I see screen tearing. It is much more visible in the flash videos.
I also see screen tearing when viewing downloaded .MKV or .AVI content, so the issue is not just with flash. I have tried Windows Media Player and VLC player.
I also have tried turning on vsync to always on in the catalyst control center->Gaming->3d applications, but that didn't make any difference. I didn't think it would because it is 2D content that I am having trouble with.
The monitor has a mode for 59hz. When I reduce the refresh rate to 59hz, there seems to be less screen tearing but it is still visible. What is the issue?

I was having the same problem - I think I remember figuring it out. It was because I had set windows to display everything at a zoomed level - you do this in Control Panel > Appearance and Personalization > Display. Set it back to 100% and the tearing problem should disappear.
I think it's likely due to a subpar graphics card driver.
