Stuttering Playback of iMovie 6.

I have a problem of iMovie 6 playback on an iMac, pausing for a second or two and then resuming to play.
Can anyone please assist with a solution?

Hi yuruga:
Do you have the latest version of iMovie and Quicktime installed?
iMovie HD 6.0.1
http://www.apple.com/support/downloads/imoviehd601.html
QuickTime 7.0.4

Jerky playback of iMovie 6

Can anybody tell me, if Apple is going to fix the issue of QUICKTIME 7.5 vs. iMovie 6.0.4?
Reverting to a prior issue of Quicktime using "Pacifist" is not an option because the latest
version of iDVD will only function with Quicktime 7.5. and I like iDVD 7.0.2.
I find it hard to understand that in spite of the great number of disenchanted iMovie enthusiasts
Apple is not moving faster in finding a solution to this most annoying iMovie problem.
Hank

I read your comments about using the option to 'Play DV project through to DV camera' with great interest. Although I have made over 100 iMovies, my recent one is the first one I've done after upgrading to QuickTime 7.5. I did that by accident, clicking on it instead of another option. It was already installed before I realized what happened, so I just went with it. I knew that Klaus1 had posted that he had had no problems with it, and my computer is similar to his.
Everything went well until I added my audio clips, and the stuttering began. I had been used to this in iMovie 5, and somewhat in version 6, so I knew that my edits would be fine and the disk image and burned DVD would play just fine....and they did.
However, one of the reasons I have continued with iMovie 6 is that I want to export my finished iMovies back to DV tapes for preserving them. Usually, I just connect my Sony camcorder, click on Share, video camera and I am set. This time, I could not get the export to the camcorder. Everything looked ok, the connections were fine, and the movie played smoothly.....but only the audio went to the camcorder. I checked it out, since another camcorder had stopped recording video, but would record audio. No, this one was fine.
I then tried the 'Play through to DV' option, and had to reset the camcorder to dupe/rec CTRL, a setting that I previously had not had to select.
Amazingly, it worked flawlessly!
Because I had already burned my DVDs, saved a disk image of the project, and now had a DV tape of the iMovie, I deleted it, so I cannot try to see if that option would eliminate the stuttering playback of my iMovie, but I will definitely try it with my next one.....already have it started!
Thank you for posting that solution. Will let you know if it works.
Meanwhile, Klaus1.......congrats on Level 4. ....and why do you not have the stuttering problem?

Stuttering Playback on iMac

I am experiencing stuttering playback and a strange noise on playback especially when unrendered h.264 is involved. When it works, it works fine but occasionally this will happen:
www.givethatmanajob.com/Public/issues/StutterPlayback_a.mov
I am suspecting my GFX card may be having trouble. All software is current. Any throughts?

Sometimes I do transcode, sometimes not. The problem happens intermittantly regaurdless and I started to suspect that it was h.264 that was given issues most of the time so I shot some test video on an iPhone. In the original post the video I linked to shows footage that was *not* transcoded.
Coming from an iPhone means nothing, especially as the iPhone, whatever iPhone this is, shoots non-standard video formats.
An iPhone 4s shooting h.264 1080p .mov
In the world of tapeless media, this is pretty standard.
I understand that H.264 is a long GOP format, and not optimized for editing hence the desirability to transcode to an intraframe codec such as ProRes. However, one of the features of FCPX is that it is designed to handle h.264 footage because a lot of video is shot that way these days.
Coming from an iPhone does not mean nothing. It means the company that designed the software capable of editing h.264 also designed the software and hardware that shot the footage in h.264 format. It means we can expect that at least some thought was put into them playing well together. It means that if I shoot some test video on an iPhone, put in on an iMac running FCPX without filters I should be able to expect smooth playback all else being equal.

IPod nano: Stuttering playback

I've been having intermittent problems with my ipod nano (~6 months old) that manifest as stuttering playback. This happens seemingly at random, affecting all sorts of tracks, which then play fine at other times. The stuttering can be slight or so bad that the whole playback comes to a halt. Turning the iPod on and off doesn't neccessarily solve it, thought it can, and it can also go away of its own accord!
Has anyone else experienced this? I've tried the reset and updated my iPod - neither helped.
Next step, return to Apple and get ripped off for p&P and handling? Not impressed with this company or their 'customer service'
Any advice would be appreciated!
Cheers

Hi,
Casper G - I've not restored it yet. I'll give it a go tonight.
Deluded, I've never tried with a podcast. All my issues are with music (either converted from mp3 ripped from a CD, or downloaded direct from iTunes) and audiobooks.
Apple's response to your issue is pretty pathetic.
ibkidd37 - no I don't rate songs. This isn't an issue with accidental fast forwarding. The playback stutters (not skips) and slows and then either corrects itself or grinds to a halt.
Is there any other way of getting technical support other than asking the forums and hoping some other paying cutomer has had the same issue and solved it?
Cheers

Stuttering playback with all footage. New CC 2014.1 install

I just installed CC 2014 on a mac. Still have CS6 too. I'm getting a very strange stuttering playback issue. Looks like 10 frames per second. then crashes. Cleared preffs and rebooted but didnt fix it. I have tried several types of footage and all plays back the same. Main footage is 24p C300.

Hello Erik,
Sorry you're having trouble.
Can you give us the specs of your Mac? Include info on RAM, CPU, drives, OS X version, GPU type and driver number.
Is this a new project or one you updated from an earlier version of Premiere Pro?
Here are some other things I'm recommending for Mac users for this version:
Sign out from Creative Cloud, restart Premiere Pro, then sign in
Update any GPU drivers
Trash preferencesI read you already tried this.
Ensure Adobe preference files are set to read/write
Delete media cache
Remove plug-ins
If you have AMD GPUs, make sure CUDA is not installed
Repair permissions
In Sequence Settings > Video Previews, change the codec to one that matches your footage
Disconnect any third party hardware
Reboot
Some users are reporting anomalies with certain footage. To fix it, they rename the folder the media files are in, then relink in Premiere Pro. You may want to try a test with a few clips rather than the whole project first.
Report back if anything here worked for you.
Thanks,
Kevin

Stuttering playback issues

Is anyone have a solution for smooth playback all files are pro res 422 the sequence is about 30 min. and is outputting to a monitor through a Kona 3g card we are getting stuttering playback and cant seem to fix it any suggestions?
Jesse

What are the sequence settings? I got pretty bad playback until I created a ProRes template.

ITunes stuttering playback

After the big OS X Leopard update, iTunes started skipping or stuttering on playback. It does it often enough that the program is basically unusable. The skipping is NOT related to internet access by my mail program (Mailsmith) or web browsers. It is NOT an mp3 file corruption problem, since the stuttering occurs in different places with each replay of the same song. The songs are those loaded from my own CD's and played flawlessly before the software update. The usual rigamarole of trashing preferences and resetting PRAM has not changed anything.
I have noticed other people with the same problem posting on different boards. I assumed that the 7.6.1 update to iTunes would address this issue. No such luck.
I am at a loss. I have an almost new MacBook which worked flawlessly until the update. I am very disappointed with Apple that 1) this issue is not addressed, and 2) that it is impossible to contact anyone knowledgeable about how to attempt to fix this. As a legacy Mac user (first 128K Mac bought on 2/24/1984 and many, many Macs since, this is a new type of helpless feeling.
Help!

This is a widespread issue, search the boards for "stutter" .... there must several hundred people posting on these forums with the same issue.
I have my 300GB + iTunes library on an external WD My Book Pro (a 2TB version set up as a 1TB RAID mirror) connected via FW800. I solved my stuttering playback problem by transferring my library to another external FW800 drive with two Seagate 200GB drives configured as a RAID stripe.
Thats all I've found so far.....

Imovie 5.0.2, Stuttering playback and out of synch audio with visual.

I have edited a movie on Imovie HD 5.0.2, it is about 50 mins long. When I came to record back onto my Sony DCR-HC42E camcorder (I don't have a combo drive on my Imac) the playback is not acceptable. It stutters, freezes and after a while the audio becomes out of synch with the visual. The playback is generally not smooth enough either. I have updated to the latest operating system. I have chosen standard quality playback from the preferences option and am very frustrated at the poor results.
I have 20 GB of space left on the computer.
If anyone can suggest a solution I would be most grateful.

Mark, if your Mac has just 256MB RAM it's possible adding more RAM will improve playback and your export to the camera. I wouldn't bet on it, but it's certainly worth a try. (You need more RAM anyway, so it's a good idea nevertheless.)
There may be another way to successfully export your project to your camera. Even projects that "stutter" when played in iMovie often export correctly to QuickTime. (The export to QT is not time sensitive, unlike the export to the camera.) You should be able to export your project to a Full Quality DV movie, one of iMovie's built-in export options. Exporting to QuickTime "flattens" the movie, making it easier to play.
You would then import THAT movie to a new iMovie project. That project will probably export successfully to the camera.
You may want to test this by exporting the first few minutes of the project. (To export a group of clips instead of the entire project, select them and use the checkbox button "Share selected clips only" that you'll see in the export dialog.)
You're running low on disk space, so here's a trick to avoid iMovie having to make yet ANOTHER copy of the Full Quality movie when importing it. The movie will be about 12GB; it won't be small.
Instead of importing the Full Quality movie to a new project, create the new iMovie project, Quit iMovie, open the project package (Control-click on the project icon and choose "Show Package Contents" from the popUp menu) then drop the Full Quality movie into the Media folder. Re-open the project. The Full Quality movie appear in the iMovie trash. Open the Trash window and drag the clip to the Timeline. Save, then export to your camera.

Stuttering playback on editing monitor

Playback of movie being edited on the editing monitor is erratic and stuttery. I went to iMovie HD Preferences and selected both "Standard" and "Highest" playback modes to no avail. The stuttery playback continues.
However, when I click on "full screen playback", the stuttering ceases and playback smooths out.
I also encounter annoying delays in response to start and stop play commands in the editing process.
The movie, currently 46 minutes long, contains 100-110 stills but no slow motion scenes. Other than a half-dozen scrolling titles, all the rest is video.
Any ideas as to what's causing the stuttering and delay problems and their solutions will be much appreciated.

If your project contains audio clips as well as video clips, you might be seeing the slowdown that occurs when the project contains many audio clips.
More about the problem here, with workarounds:
http://discussions.apple.com/thread.jspa?messageID=2597033#2597033
The precise number of audio clips that causes this problem seems to vary from Mac to Mac. As few as 30 audio clips has been reported.
The project I just tested plays poorly except in Full Screen mode. That wasn't true in the others I tested, but apparently Full Screen does work for some projects. So what I see here is consistent with your experience.

Stuttering playback

Hi
I am editing in a ProRes LT 422 time line using ProRes LT material 1920 x 1080p. This is on a Mac pro Quad-Core Xeon with 6GB DDR3 and a 4TB esata stripped raid, using OS x10.6.4 and Final Cut 7.
I have been suffering from intermittent playback issues since this project started, it has been inconsistent whole sequences playing through perfectly then not. Changing the RT and quality does make a difference but again not consistently.
Then I started to look at the front slate which is made up of a B/W jpeg and several layers of none animated text. this is the only material in any of the sequences that was not prores. Re formatting them as a prores movie and limiting the layers to two levels of text appears to have stopped this stuttering. But I am not convinced that its that stupid! has anyone else seen this kind of behaviour is my fix a real fix or am I missing something else.
Thanks in Advance
Steve

Moving from LT to SQ did not help the issue. To explain a little further playback actually stops on this slate in multiple sequences @23.98fps and then will affect the playback of any other media in the time line. Swapping sequences will sometime reset the playback, sometimes not. My issue is that this is a Prores LT project as prescribed by the client, changing the setting is not really an option. What I really want to understand is why this jpeg still and text layer can affect things so badly. The jpeg is not corrupt; I have tried resetting the user preferences that made no difference.

Stuttering Workaround (and iMovie observations)

I too had experienced stuttering issues once I really got into a project in iMovie HD. Here is what I found, and how I fixed it:
I had dozens of short clips, sound files, and narration in the lower project bar, the area in which you make your linear project. My linear creation was about 40 minutes long. I had dozens more clips up in the clip storage area.
As has been noted many times, iMove HD starts to stutter the audio and skip about the video. Yet, as other posts noted you could export to Qicktime and have it pipe-out ok (mostly). I found the same was true if I exported what was in my project bar back to my DV camera: While the video and audio skipped and stuttered on my G5, it was coming across smooth in my camera screen...for about ten minutes. Then the video began skipping in my camera too.
My next intended workaround found an interesting problem with iMovie. My intended workaround was to delete the first ten minutes (that I'd gotten on my camera in nice form) from the project bar, and then simply record the next ten minutes or so in good fashion, and so on. But, with the first ten minutes gone, the export now lasted a good twenty minutes without beginning the skipping in my camera.
Ah-hah. iMovie must have a problem holding a lot of data!
So, I deleted all unused clips from my storage area, and tried the whole export again. This time it ran flawlessly to the end. I now had two perfect pieces of a movie (video, narration, music, sound effects) in my dv camera.
This tells me that iMovie has a problem holding a lot of separate data while trying to play video and audio.
I imported my two pieces of finished video that were on my camera into a new iMovie project, so that now I only had two big clips. iMovie handled these two clips flawlessly. I made some minor adjustments, put the pieces nicely together in the project linear project pain, and ran iDVD. It all went fine.
In the end, iMovie just could not handle so many pieces of video and sound.
Interesting.

Stuttering playback...what's up?

i videotaped some 1080i clips and imported them to imovie.....and it plays back in imovie fine, even in full screen mode. but when i export the clips, and play them back in quicktime 7.1, the video is very stuttery....WHY!? i'm on imovie 6.0.1.....and my old HD videos play back fine in quicktime 7.1.

change the audio setting in the quick time player settings to a lower rate. your settings may be defalted at 44.1 and the rate, when slowed down, will stop the stuttering.

Stuttering playback after export

Hi,
Sorry if such a question has been answered elsewhere but I have looked around for the past few hours and been unable to find an answer. However I am new to Adobe Premiere Pro (and video editing in general really) so perhaps I am missing something fundamental.
My basic problem is that I have created a video which plays fine in the Premiere preview (I have CS4) but after exporting it, the video becomes very stuttering and jerky. To be honest I'm a bit unsure of a lot of the technical terms etc but i'll try to provide all the info that may be of use.
I own a Sony HDR SR10E camera and so my orignal video files are shot (to my knowledge) in 1080i 1920x1080 25fps PAL AVCHD ... (I've probably repeated myself there or something). I am trying to put the video on youtube/vimeo and so have read to try to encode using the H.264 codec, at 1280x720, 25fps, trying to deinterlace it (didn't entirely understand what that meant but read that if you choose "None(Progressive)" under "Field Set" AME would automatically do it. I've tried a number of variations of the settings but every time after it has finished its very jerky etc.
I did try exporting it as a f4v file and the jerkiness had gone but i'm not sure if you can use this format to upload to youtube/vimeo etc, and anyway I don't understand why the h.264 codec is causing this problem when it all plays fine in premiere itself.
If any more info is needed, please say. I'm sorry if i'm making some massive error but although i've spent the last 8 hours trying to understand all the technological terms and sort it out myself I haven't been able to and any help is very much appreciated!

i have the exact same problem... i used all the same settings as I did in CS3 but the h.264 output is ALWAYS choppy. I even used the program "gspot" to make sure all the settings were EXACTLY the same, and they were... but anything output in cs4/adbone encoder comes out choppy. It's not a framerate issue, it's not a problem with the source files (projects in cs3 work just fine).
I am so frustrated at this, mainly because I can't open my CS4 files in CS3 and I *need* to encode in h.264. Output to other formats like WMV work fine, but unfortunately the place i upload my videos rejects the files i upload, even though they look OK on my computer.
very frustrating, I have no idea what to do. I've tried everything in project settings as well as encoder settings but the problem still exists. All my old movies, encoded in CS3, all playback flawlessly. Again, every single setting is the same, and I have applied the Premiere update, as well as the encoder update without any luck.
HELP

Adding Transitions freezes and stutters playback in Preview.

I'm posting this as a new issue. Since I've narrowed down my "stuttering/freezing on playback" problem while in Preview/Edit mode.
This begins to happen as SOON as I add a transition. Whether I add it automatically, or manually.
The clips play fine without transitions in the project and the Event window. These are clips from a Kodak Zi6, I believe shot HD at 60fps, and I'm using NTSC 30fps to create the project. When I "get info" on my clips, the codecs listed are H.264 and AAC, dimensions 1280x720.
When the Movie Project is exported & viewed in QuickTime, it plays smoothly.
Any ideas are greatly appreciated, as I'd like to preview my work as I go!
This movie is LESS than one minute long!

UPDATE - A workaround?
after what you posted about converting the file to the apple codec AIC - it occurred to me to try this.
Put a clip in the project browser - it starts stuttering - with or without transitions.
click on clip and select "clip adjustments". Now when you need to run slow mo you click the "convert clip" button. Do this even though you don't need to slomo the clip and it will come up with "converting whole clip" - this can take a while if the clip/event the clip is from is quite long. Hang in there. Click done. ......and......
all works perfectly.
It seems like the converter converts the whole event because if you now choose other clips from the event they too work with no problems! So looks like... before you start run the conversion on a clip from all the events you are about to use and then you can work normally...
I've run a test project and now transistions/ green screen/ PiP all work smooth. IS this the workaround we needed?
Do you know if the convertion to AiC changes size or quality? I cant tell at the moment. But it works! (well so far.....)
Please let me know if this works for you too - if so it might be worth starting another thread as so many people are having the stutter problem and i've not seen a workaround yet that's easy to do.
Anyone?
Apple - we should not need to do this!

Why do I get a perfect realtime playback in iMovie but a jumpy one in Premier CS6?

If it's my hardware then I should get the problem in both programs. Am on a Macbook Pro, 10.6.8, NVIDIA GeForce GT 330M and have tried setting playback to 1/4 quality. I'm not using any crazy effects, the footage is HD from a Gopro. iMovie has no problem doing what I've tried doing so far in Premier.
Thanks for any help, am hoping I'm just missing some obvious setting as I'd like to be able to do my editing in Premier.
Leah =)

GoPro pretty much expects you to convert to the Cineform codec for editing. So much so, in fact, they bought the company.
The program is free. I suggest that you take a look at it before doing any more editing of GoPro footage.
