Choppy playback since iTunes 9

I just installed iTunes 9 on my laptop, a Powerbook G4 867MHz running Mac OS 10.5.8. All of the playback from the local library, Home Sharing, and radio is choppy and unlistenable. Is anyone else experiencing this, or better yet, does anyone have a possible solution?

I had same problem - i phoned apple. they gave me a solution which I can't remember 100% - it seems that the safety lock on the HDD kicking in to upset playback on itunes. the tech guy told me to SHUT DOWN remove all power and other cables. Then I had to press shift-option-control (i think it was please check to confirm!) for 30 seconds (computer is off during this) then press power button and hold while it starts up (again I can't remember how long so please check). After this itunes works flawless and has done for a week. So if this is your problem then either search for better instructions or phone apple. I wasn't charged and not part of apple care i.e. FOC. Hope this helped (a bit!)

Choppy Playback With iTunes 8.2.1

Hey everyone,
Ever since iTunes 8.2 (and now in iTunes 8.2.1), I have noticed that when opening other programs, or sometimes when I load new Web pages, my music playback will chop for just a second or two, and then continue playing as usual.
I've done what was suggested on the support pages aimed at troubleshooting sound and playback issues, and those suggestions did not seem to do any good with my issue. Like I said, this started right after updating to version 8.2; prior, no matter how much of a load my system was undergoing, I never seemed to have any sound-related issues.
I've noticed that if I open the Task Manager, and set the priority for iTunes.exe to AboveNormal, that the issue goes away. I'm just curious why this seems to have cropped up after the 8.2 update.
Thanks for any information!

I had the same issue with a Thinkpad X200s laptop's built-in MM keys plus an old Microsoft Natural Keyboard Pro's MM keys, and found this solution in my bookmarks which is working great for me in Vista 64 + iTunes 8.2.1.6 with both sets of keys:
http://www.everythingitunes.com/os/windows/2008-01-04/mmkeysdll/
It had also worked a year ago on Vista 32 for a Dell M1330. Very easy too -- I just placed the .dll in the Plugins directory and restarted iTunes.

Choppy mp4 playback in iTunes

Until tonight, I've never had issues with video playback in iTunes. I have a library of mp4 video files that I've played successfully in the past with little or no video quality issues.
All of a sudden, none of my videos will play correctly in iTunes. The video is incredibly choppy, with a new frame or two playing every 30 seconds while the audio plays relatively normally. If I open the same file in another player (VLC or WMP), the file will play correctly with no choppiness. In fact, I can play the video file in both players at the same time with zero quality loss, so there's no lack of computer power that would cause this in iTunes. To the best of my knowledge, nothing changed on my system to prompt this - I was literally in the middle of watching a video when it happened.
After experiencing this issue, I upgraded iTunes, Windows, and my video card drivers to the latest versions/drivers (rebooting several times in the process), but this did not help. Next, I followed all of the instructions in the relevant support document (http://support.apple.com/kb/TS1718), also to no avail.
For the heck of it, I rented an HD movie from the iTunes store and had the exact same problem. I originally thought that this might be an issue with my media, but it is clearly not.
I often stream video from my PC to my AppleTV, and this is also experiencing the exact same choppy video (as you would expect).
I have no clue what else to try. I would prefer to watch the videos in another player, but this is sadly not an option if I wish to continue using my AppleTV. Has anyone else experienced this (or a similar) problem? I'm at my wits' end, and very unhappy that I spent so much time transferring my video library into iTunes. Nothing substantial changed on my computer that should have caused this, especially not in the middle of watching a movie. Any help or further ideas would be greatly, greatly appreciated.

Solution: format computer because iTunes is terrible. Problem "solved," I guess

ITunes 12.1 for Windows (64-bit - for older video cards) did not fix choppy playback

After reading all the other posts I tried installing the (64 bit for older video cards) and it did not solve my choppy playback with Music or Movies. I am running windows 8.1, Intel i7-4500U CPU @ 1.8GHz, 8 GB RAM, 64-bit OS, x64 based processor, DELL Inspirion 15. Never had problems until upgrading to 8.1 from 8.0.

Did you see if changing the Play Audio Using select in Edit > Preferences > Playback to "Direct Sound" resolves the issue? Otherwise you may want to consider rolling back to 12.0 and waiting until a future release is shown to resolve the playback issues in 12.1. See Turingtest2's notes on Troubleshooting issues with iTunes for Windows updates for steps needed to completely remove all installed iTunes components, and for links to the 12.0 installers.

I may have a solution for choppy video playback for iTunes Windows users

My setup:
- Intel NUC (i5)
- 8gb memory
- Intel 5000 Graphics with 1GB memory (share of system memeory)
- iTunes 12
- iTunes library on NAS via GigaLan
Had problems with very choppy and freezing HD video playback in iTunes and tried everything... Every other player works fine.
1. downgrade audio playback
2. played with Quicktime settings
However, I think I might have a workaround. You need to do the following,
1. Install Quicktime 7
2. Install iTunes
3. Download ffdshow (Sep 2014 version) and install the codecs: pretty much leaving all do default
4. Set audio quality in Sound and Quicktime options in control panel, and iTunes to 16bit 48k
5. In advanced options of Quicktime in control panel, deselect "Direct 3D" & "Enable directdraw on seondary display", ONLY tick "enable directdraw accerleration"
Well, at least this works for me for now.
HOWEVER!!!
@Apple! You need to address this issue once for all, I can't believe there is no solution. As a paying customer who buy quite a few of your movies in iTunes, I expect to have a harssell free experience. Consumers should NOT have to go through all these troubles trying to fix a product you have released and making billions out of.
Reason why I switched from Android to Apple for my phones and tablets is becasue of the seamless user experience, regretfully I have to admit, this advantage is quickly going away. The amount of glitches in your recent ios updates and itunes are simply unacceptable.

Downloading videos on 7.0.2 hasn't worked as well as everyone had hoped. I still can't get mine to work, but i do know a few people who haven't had trouble with the newer itunes.

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

FCP7 with snow leopard - choppy playback in monitor

Ive been fine running fcp6 with a jvc 1080 hd monitor connect via DVI from my MBP duo intel 2.4 (4 gigs ram)
its not the fastest setup but its been fine.
ive noticed my playback into my monitor is always choppy now since upgrade to fcp7 and snow lep. i have it set as DIGITAL CINEMA DESKTOP PREVIEW- FULL SCREEN, when i set displays to mirror and use DIGITAL CINEMA DESKTOP PREVIEW - MAIN it plays smooth and normal. any ideas?

I am finding actually, that playback is smoother when moving my cursor along the timeline when a simply zoom in on the timeline. Does that make sense to you guys?

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

Playback of iTunes Contents Stored in iMac mid-2010 (upgraded to Mountain Lion) using Apple TV

I am not 100% certain that upgrading to ML is giving me issues with Apple TV playback (not mirroring) but I AM having trouble with playback of music and movie stored in iTunes/iMac mid-2010.
I have an iMac mid-2010, 3rd generation Apple TV, cable broadband connection, and linksys wireless router.
Ever since I upgraded my iMac from snow leopard to ML (and yes I followed all directions and updated my apple TV as well to the latest software version), Apple TV takes as long a 5 to 10 minutes to play a song in my iTunes/iMac.
I thought it was the broadband or wi-fi connection so I tried netflix streaming using apple TV and it was fine.
Playback of movies stored in iTune/iac are also affected and it takes a long time to load as well.
In addition, once the content is playing, there's lagging/buffering and the playback stalls.
What's going on? Is it the speed of the wi-fi or broadband as suggested by Apple troubleshooting tip and this forum? The only thing that has changed from the time that playback of itunes contents using apple TV was working vs. not is the upgrade to ML.
Anyone else experiencing this problem? Recommendations?

So by switching your router to one that was WiFi "N" allowed you to obtain higher speed and allowed you stream from your computer to your apple TV/TV without any issues
My Current Router is an older Wireless G Router but I have no issues at all with this router it works with all my devices at home and I havent had any problems what so ever. However my room is the only room in the house in which I stream wirelessly to my TV most other devices are just tablets and other laptops that are connected to the network.
Also I was wondering if this is more of a networking issue rather than a graphics card or OS issue? Im not even sure where this falls in place.
Also I would just like to thank you Gnarlodious for your input

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.

Problem with video playback with iTunes

Several problems :
Problem with video playback with iTunes -
Since about a week, When I launch a video, it takes a long time to get started, then only the sound starts with no pictures - If I press pause then play the video is played normally. Did anyone face or heard about same kind of issue .
Problem with permission disk errors
After re-installing White Tiger and After I installed the last OSX 10.6.5 update
I found the following problem
Group differs on "Applications / Utilities / AirPort Utility.app / Contents / Resources / wanArrow.png", should be 0 instead of 80.
Last but not least :
My computer seems slow - I have 60gig free on My hard drive and I test my hard drive and everything seems all good .

What was the fix for this? Everything has sucked for my itunes video playback since the last major revision release.

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!
Stephen

Hi SDCone,

Me, too. But as soon as I re-synched the project and moved back, the

CC, I am using PP 6 more often.
As tough as that is to take, I appreciate your feedback.
Have an awesome weekend,

HD playback in iTunes 6 blocky

I've added some HD video from the HD Gallery to my library, but when I play them back in iTunes the video is not full res and looks blocky and crap, but it looks fine when opened in QuickTime player.
Is it just me? Or is iTunes video cripled/badly designed?
Cheers

Bah, I pulled off the first 2 replies when I had net access and now loads of people have posted!
Sara - If they had half hour programs in HD they would be about 630MB, which would take over an hour and a half to download on a 1Mb broadband connection. Yes the quality isn't great, but it's not bad. I've not seen anything longer than 11 minutes and I'm using a 12" screen but it is watchable. It's all a problem of bandwidth.
Curt - that page doesn't show requirements for 480p, which is what I'm using. The files I refer to play perfectly in full-screen mode in QuickTime on my PowerBook. My issue is with iTunes.
I was just assuming that since iTunes uses quicktime for it's media support, and that all protected files play fine in quicktime that it would work the other way with HD.
I tried using MovieGallery (3rd party app, like iTunes but for video) and had the same problem with HD playback.
I'm now thinking that Apple has deliberatly limited HD support so that it only works full res in QuickTime, in preparation for some i-App that will manage your video in a similar fasion to iTunes and iPhoto. I think everyone can see that having video in iTunes is clumsy!

Choppy playback in fcp x 10.1

Since I updated to FCP X 10.1 I get choppy playback with almost all my clips. From old HDV to h.264 and even Poxy files play with audio drop outs, and mostly choppy. On the drive the files are hosted I get 240 MegaBytes/s. Editing is very unresponsive. Sometimes I have to wait for 10 or more seconds until the playhead is ready.
Seems to me like a bug, as that wasn't the case in Final Cut Pro X 10.0.9.

What you are experiencing is NOT normal.
I would try deleting preferences, and also checking the drive.
How big is/are your library(es)?
If you imported everything into a big library that may be causing some trouble.
Also: how much RAM, and what does Activity Monitor report about RAM pressure? (don't worry if it appears that there is no free RAM, unless RAM "pressure" is high and/or there is significant swap space).
If I had to bet I'd say a very big library may be to blame. You may need to give a thought on how best to organize things with the new media management model. The solution depends on your workflow, but the ability to have manageable size libraries that you can open and close as needed, and move from one drive to another, together with the easy handling of managed or external media, open up a number of great possibilities.
