IMovie playback problems

Hello again,
I would appreciate some help with a problem I have with iMovie.
I have created a movie that has taken me all weekend to make so far, it is about an hour long, it is a mixture of still photos and movie clips and is currently made without a theme. I now need to put music against it but before I do I have played it back and the photos come up on the screen in random order, sometimes they are distorted and repeat several times. When I play back in preview mode and watch the scroll bar move through the movie, it works perfectly. The problem only exists when I play it back as if I was watching the full movie.
I have had some previous advice to tidy up iPhoto where I rebooted the machine holding down the alt and command buttons and selecting all options to tidy up the photos but this only half helped. The tidy up was helpful in enabling the playback to be better but now the full move screen play back.
I have made many movies before without problem so it I don't think it is user error. I have checked to see if I have deleted any of my movies or photos that are used as I have found this to be a problem in the past, but this is not the case this time.
All suggetions welcome.

Hi
If You tidyied up iPhoto - then I would
• Trash iMovie pref files
• Repair Permissions (Disk Util tool)
• Repair Hard Disk (Disk Util tool - BUT YOU MUST START YOURS Mac from DVD or External Hard Disk - It can not make brain surgery on it self)
Last resort for me would then be to
• Make Copy of Project (severals)
• DO NOT touch Original Project
• Split one Copy - trash one half - see if other RUN OK
• This splitting and deleting - is a very rude but functioning way to scale down where the problem originates if it is embedded in the movie project e.g. a bad Clip, Photo or Audio file.
BTW I do:
Video - Only StreamingDV or AIC - Video Codec
Photo - relative small (10Mb) .jpg - NO .bmp or other formats - all converted to .jmp first
AUDIO - ONLY .aiff 16-bit 44.1kHz or 48kHz - NO .mp3 or directly from iTunes or other ailient formats - all converted to .aiff first
By doing this I've scaresly no problem with my videos.
Yours Bengt W

Quicktime 7.5 causes jerky iMovie playback

When - oh when will Apple fix the "Jerky iMovie Playback Problem" caused by Quicktime 7.5?
I would love to see a response by somebody from the Apple Corporation, or are they
too busy with the iPhone and iPod?
Hank

Hiya,
and hello from London. Just a thought: you could post Apple feedback of the problems you got:
http://www.apple.com/quicktime/feedback/
It might be an idea to put more technical feedback in there (e.g. open applications/utilities/console and see what happens, when QT IS actually jittery.:~/
Also compare that with what's happening in activity monitor (e.g. are the processors running unusually high, compared to other QT use? or is the memory low? or is harddrive space low?).
If this is a bug that needs fixing, by giving the technical data to apple, this can be used to issue a fix.

Update on imovie 5 problems

I'm starting a new thread. Sorry but I'm getting lost as to whom I'm talking to & what I've written ...who's on 1st what's on 2nd etc.
So the big news is ... On this 3rd total re-install of Tiger I've added something else to the install.
Classic install. And only Slick plugins with their updates.
It's early days but NUMBER 5 is Still alive! No audio clicks between clips, faster response from 5 . This is on a 1hour 40min project which has become the test bed. Faster response from firewire output to T.V. monitor also is noted. No crashes after 30min of working with constant changeing of effects & transitions. Haven't tried titles yet.
SO... I updated to 5.02 & Quicktime 7.02. Everthing remains stable so far. Again as before I can see no obvious benefit in these upgrades but I'm only looking at imovie so far.
So tell me, those of you with problems do you have Classic installed? Is Classic the answer? Do I "sound" desparate?
where did i put my pills.....
Mark

Can't remember the exact wording of what you refer to-"Install Mac OS 9 Disk Driver". You cannot boot in OS9 anymore. Only Classic.
The note below the "Mac OS 9 Drivers Installed" checkbox in Disk Utility says this:
"Select this option to use this device on a computer running Mac OS 9. This option does not affect Classic."
My Mac can boot in Mac OS 9 as well as Mac OS X, which may be why I'm offered the checkbox. Perhaps the checkbox isn't offered on Macs that don't boot in 9?
It had occurred to me you may have turned on that feature for the first time. But if you can't boot in OS 9, I suppose not.
It is certainly possible that reformatting the drive might have contributed to eliminating an iMovie playback problem, I suppose. Hard to say.

New iMovie '08 problems -- FireWire or new device issues?

Not sure if this is an iMovie '08 problem or an OS X problem. Here's the story --
Prior camcorder was a Panasonic, MiniDV format. Hooks up nicely with iMovie, via FireWire (400). I also have a WD My Book (500 GB) device to store the raw data (Event Library), which connects via FireWire (800). In the past, all three devices (Panasonic, My Book and MacBook Pro) all played nicely together.
Fast forward to now. Bought a new camcorder (problems with the Panasonic). It's a Canon ZR950 (MiniDV). With iMovie running, I first connect the WD device which is successfully mounted. I then hookup the new Canon and within a few seconds I get an error about a "device not cleanly shut down" (or words to that effect). Odd .... and when I try to connect to my new camcorder, I get a "no camera connected" error.
Rebooted, retried .... same issues. Another time I first connected the Canon and this time, iMovie successfully sees it. I go to connect the My Book and then the camcorder drops out.
So, it seems I can have only one FireWire device connected at a time, which is odd since I didn't have this issue with the old Panasonic.
Help!

Interesting that you based your purchase on CR magazine because I too use it like a bible. However, when it comes to video cameras, I think they are way off base when not considering the editing side of video making that goes along with any camcorder. Who shoots video simply to plug it into a TV for playback?? If they were doing responsible reporting on this particular subject, they would also include computer capture and editing details in the reviews. Lots of the new format cams don't even work with Macs and the ones that do generally give lesser quality after conversion than what you can still get with tape. At least you made the right decision there!

Playback problem - video playback stops; any suggestions?

I have distributed about 20 copies of a DVD I made using iMovie and iDVD v4.x - and about 5 of the discs are reported to freeze during playback. Because not all of the 20 discs have been viewed, it's possible the percentage of discs with playback problems may be even higher. No two discs are freezing at the same spot, or even in the same movie (there are 3 short movies on the disc).
I got no errors during burning, but I did not 'verify' each disc after burning, either. I did play back my 'master' disc on my home DVD player to make sure it was OK before using it to create a disk image - which I used to burn all the other discs.
Some of the discs I burned from the disk image using Toast Titanium 6.1.1, until I discovered Apple's Disk Utility was actually a little faster. No way to tell now if the 'bad' discs are all from the same burn software. Though both Toast and DU gave me an option to burn faster than the rated speed, I used the rated burn speed of 8x, and I did not do anything else on the Mac while burning the discs.
My first thought was bad media. I used both Memorex and Sony DVD-R media (Taiwan) - there is no easy way to for me to find out if all the 'bad' disks are one brand or the other - but hopefully these brands do not have a 20% rate of defective discs.
My second thought was format-player incompatibilities (-R vs +R), but replacement discs, using the same media on my end, solved the problem for most people (one person's replacement disc froze, but at a different spot than the first one).
My final guess - I wonder if the playback problems might have something to do with the stick on labels I used? These are a Memorex brand product called "CD&DVD" labels, but the fine print on the back says: "Warning: Using a Standard or Full-Face label on DVDs may result in the disc becoming unreadable."
Any solutions?
Quicksilver G4, 867 Mhz Mac OS X (10.4) Pioneer DVR-108 (not OEM), firmware 1.20, PatchBurn profile

I just wanted to add my 2 cents. I haven't been on this forum for months. I've been happily making DVDs in batches of 10 -50 to distribute. I've been making them in my emac. Occassionally I'd get ones that wouldn't play in a client's player. The solution was to send a replacement. Usually that worked. Often I'd send a replacement that wouldn't play in one client's player but found that the disk would play in another client's player. The worst case was when the ist three DVDs I sent to one person wouldn't play, but the fourth did. But most of the time, the second one I'd send worked fine (All of these were made in the same batch from the same media (usually Fuji or Verbatim).
Recently I started getting lots more than usual complaints about problem DVDs. I checked out a bunch of them by actually playing them on both my computer, and a stand alone Cyberhome player. They were all made from a particular batch of Fuji media. Now I've previously burned hundreds of playable DVDs made from Fuji media, so I imagine it is just a fluke. (I hope) Some of them would play perfectly all the way to the last 5 minutes of an hour long presentation, and then start stuttering. Some begin stuttering in the middle. Several wouldn't even start up in my cyberhome player. Most of them would end up freezing at some point during the stuttering. The stuttering was never at the same exact place on any of the DVDs.
As an aside, I discovered something that I didn't know was possible. When a DVD froze in my cyberhome player at the menu stage, I'd push the eject button, remove the DVD, and the menu frame was still visible unchanged on the TV until I turned off the player or put another DVD in! I guess there must be some sort of cache in the player that stores the image. Very interesting. I've never seen that with a normally functioning DVD.
I also played each defective DVD in my computer to compare. One or two managed to play all of the way through on the computer, but most exhibited similar misbehavior on my emac. I'd say that, in general though, they all played a bit better on my computer.
Then it occured to me that there was another possible explanation. I was burning these from a disk image file that I had stored on an external HD. Whenever I needed a new batch of DVDs I would copy the disk image file back onto my emac from the external drive, and use disk utility to burn the disks. What if the disk image was corrupted? That might explain the problems.
Another thought that occured to me was the perhaps the process of burning a dozen or more DVDs in a row might cause a heat buildup in the burner and affect the burning in some way.
So I retrieved a good DVD made in an earlier batch of Fuji, made a new disk image of it, and left the image on the computer and didn't transfer it back to the external drive (on TDK media, because that's all I had sitting around), played the copy back on both my computer and Cyberhome player to make sure it worked perfectly. I then generated another dozen copies.
You may wonder how I had enough time to do all this. I'd just put a DVD in the player or my emac and listen to it while doing my ordinary office work. If I heard stuttering(it was my voice on the DVD) I'd instantly notice. I did this all day for a couple of days.
So anyway, I played 5 finished TDK disks all the way through today and they played perfectly. I guess the next test is to use the disk image of the same DVD from my external drive to see if i also get a good burn from it on the same TDK media and burner.
I did have time to do one other test though. I took a couple of DVDs that played well and put paper lables on them using the stomper system. They still played perfectly on both my computer and Cyberhome player. I'd speculate that paper lables are probably okay if they are applied perfectly, perfect centering, no air bubbles, good contact, and the disk stored in clean dry area. I've seen other peoples' CDs or DVDs with paper lables that had become wrinkled from exposure to high humidity and/or heat. I can imagine that they would tend to malfunction.
One client with a certain brand player actually took the "offending" DVD down to a AV store, and bought a replacement player that WOULD play it. I do think that it is interesting and useful to know that one brand player will play a particular particular DVD and another won't.
Since I make batches, I'm considering buying a couple more different brand DVD players, and then doing a bit of quality control - Trying out sample DVDs on all players before I mail out a batch to clients.
I hope that my observations might be useful for others.

IMovie playback choppy, Processor activity abnormally high

I am having an issue with a single iMovie project. When I play it back, it's very choppy. Yet, other iMovies playback just fine.
When I view the CPU Usage when playing back the troubled iMovie, I get 0.00 or -0.00 % Idle. While playing other iMovies, % Idle is 35-45%. What is going on. Why is this one iMovie maxing out the processor. I have no other apps open.
I have played back much more processor intensive movies previously (or so I thought).
How can I fix this? Do I just need to get a faster computer???

HI Andrew,
I use iMovie all the time. The more transitions/audio/titles/effects you add, more larger the file and the more RAM it takes. You indicated you have 768mb of RAM. Anything less then 1GB and you will more then likely experience playback issues. Here are the minimum requirements for iMove HD 06:
System Requirements
The minimum requirements for iMovie HD 6 are:
- A Macintosh computer with a PowerPC G4, G5, or Intel Core processor
- 256 MB of RAM; 512 MB recommended
- High definition video requires a 1 GHz G4 processor or faster and 512 MB of RAM
- Mac OS X 10.3.9 or Mac OS X 10.4.3 or later; Mac OS X 10.4.4 recommended
- Mac OS X 10.4.4 (or later) required for themes, real-time video effects, and audio effects
In order to use iMove in the most efficient manner, you need to upgrade to a faster Mac. I know the minimum requirements started above for RAM indicates 512MB recommended, by take a long time iMovie users word... 1GB of RAM and a faster Mac will solve your problems.

IOS Music Player MP3 Gapless Playback Problem

Hi,
I've been having this gapless playback issue on iOS now for the past few years, since at least iOS 6 if I can remember correctly. The number one reason I use an iPhone and iOS devices is for gapless playback in the iOS music player. For the last few years I've been experiencing a bug with the stock iOS music player on my iPhone 4S using iOS 6 and on my iPhone 5 using iOS 6 & 7, and currently on my new iPhone 6 running iOS 8.1.2. This only happens on my iPhones and using iOS, this bug is not found when I use my iPod classic or when playing the same albums through iTunes.
I thought it might have been spotted by other iOS users and fixed in iOS 7.1 or at least the current version of iOS 8, but instead it's gotten worse, albums that used to play smoothly between transitions now suddenly pause and jump for a split second when changing from track to track.
What's happening is, I listen to a lot of albums that are continuously DJ mixed and play straight through without any pauses between tracks, and I've been experiencing problems a lot now with random split second pauses between tracks and choppy transitions. These albums in question have been ripped from cd using the latest versions of iTunes.
For example,
I'd be listening to an album and it would play gapless and smooth for most of the album, but maybe one or two transitions on the album would have a split second pause between them, and the rest of the album would play perfectly with no pauses, skips or jumps at all.
This only happens on my iPhone, as I have a 160gb iPod classic and I've listened to all the same albums on it and never has a problem playing the album without any pauses, every album plays 100% smooth and gapless on it.
I mailed Apple about it through their feedback page on their site... https://www.apple.com/feedback/iphone.html
Hoping that they would take note of this and try and look into it and fix the issue. That was probably about a year ago now, never got fixed or got any confirmation back from them about this problem. Then last August, I'd had enough and contacted Apple support to notify them about this issue. They told me the usual story, "have you tried restoring the phone?", which I obliged and did. The problem was there on a freshly restored iPhone 5.
So they told me that they would put me in touch with someone higher in Apple to take the case further, "great" I thought.
I spoke with a senior care advisor and explained the problem and agreed to send detailed explanations of the issue and test files too so that they could hopefully hear what I was talking about. But after a few weeks of going back and forward, I finally got them to hear the issue with the random pauses, the first week they denied there was a problem and said the files played ok on their test iOS devices, so I myself tried the files on another iOS device and the same problem was there.
The last correspondence I had with the Apple care advisor was back in the end of August / start of September, and she told me that they spotted the issue and was told by the tech's that it would be fixed in a future update, I never got a when this would happen, I was just told to make sure my iOS device was up to date with the latest version of iOS. I couldn't speak to an actual technician, got no follow up support, just a vague "We'll look into it." Case Closed.
I got so sick of this problem that I sold my iPhone and iPad just after this last phone call with the Apple people, and switched over to Android. I'd being reading up on gapless playback music players and found out that there's a good few available for Android devices. I got myself a Sony Xperia Z3 Compact, twice as powerful as the iPhone 6 and half the price. I was using that for the last few months, and playing my music through Neutron Music Player app which is a great music player which plays gapless 100%
But I couldn't really take to Android OS, seeing as I've been using Apple products for around 10 years now and iOS since the iPhone 3G. So I decided to contact Apple again and see if they'd fixed the music player issue in iOS yet.
I wrote a long email explaining the problem, how it wasn't really looked at properly, and how I was a long time Apple customer and had to resort to switching over to Android because the basic music player functions on iOS devices have bugs. I took a chance in mailing this to Tim Cook's offices, I knew he wouldn't reply personally, just thought that it might get read by someone in his offices with a bit more say in the matter.
Just before Xmas, I got a call from someone from executive relations from my local Apple offices about this. He seemed nice and was aware of the problem from reading back through my emails and previous case notes from August when I opened this case originally.
We had a talk and he said he would get one of the tech's to call me too about this so that I could explain the bugs to someone more knowledgeable about iOS.
A few days later I received a call from one of the tech's at Apple and was chatting to him, explaining the problem. His response was that he thinks Apple doesn't support gapless playback on current iOS devices. From looking at the gapless playback information page on the Apple support site below, it looks like it hasn't been updated to show any iPhone models after the iPhone 3GS... http://support.apple.com/en-ie/HT201644
I was trying to explain to him how ridiculous this sounded, why would Apple stop supporting basic functions on their music player on iOS devices? It makes no sense at all? You can see that the amount of hardware devices and software that supports gapless playback today... http://en.wikipedia.org/wiki/Gapless_playback#Player_support
He couldn't explain either, he just said that because it's not listed there on the Apple support page.
Then the next day I got the follow up call from the Apple executive relations guy, he was stating that he was speaking to the tech guy that called me and it looks like Apple doesn't support gapless playback anymore, from looking at the documentation on site.
I told him how stupid this was, and how lots of music players have gapless playback as standard today. And if they don't support it now, then why does it play through some parts of the albums on iOS ok and then just randomly pause, or have jumpy / choppy transitions on the rest of the album. If it was the case, no albums would play gaplessly at all, it would be like when the first ever iPod's were released back in the day with no gapless playback and would pause for a split second between every transition.
He couldn't give me an answer and said that maybe down the line they would start supporting it again, and that I should request the feature to be added to future iOS versions via the iPhone feedback page... https://www.apple.com/feedback/iphone.html
He just kept on emphasising that it was "NOT A BUG OR ISSUE", trying to cover up the problem because the info on the site wasn't updated to show the current iOS devices. Which in itself is wrong, looking at the page it says "Supported iPod and iPhone models (make sure you have the latest iPod or iPhone software)"
iPhone, iPhone 3G, iPhone 3GS only go up to iOS 6, so that contradicts itself when the latest version is iOS 8.
The info is out of date and needs to be updated. So in August I was told, "we found the issue and will look into it" and a few months later, "it's not an issue", what's a cop out.
I was annoyed and taken back by this response, and really found it hard to believe that this was the case, Apple stopping supporting their music player on iOS devices. Seeing as iTunes plays everything smoothly and no gapless issues. I just went out and bought an iPhone 6 for €900 / $1060, and for that money you'd expect it's basic music player to work. It's total BS to think that a top computer software / hardware company would just decide to abandon basic functions in their devices, especially when we are talking about how much Apple takes pride in their products and how much more they charge for them over their competitors.
So this is my next step to try and get this problem seen and out in the open more. The more people who know about it and are aware of the issue, the better.
Hopefully more people can get the word around and get this noticed by Apple and finally fixed.
I've uploaded some test files below to show the problem. The files are mp3's and aac, and have been ripped from cd using the latest version of iTunes. The mp3's are the ones with the issue, but the aac play with no problem. If you listen to the transition at the end of track 2 (2-02 Colours (JH Re-Edit)) going into the start of track 3 (2-03 Your Body), you will notice the split second pause / jump. But listen to the aac version and compare it to the mp3 version and you will hear that it plays back fine, just as it's supposed to. Try them in iTunes too and both versions playback fine, no jumps or pauses.
You can download them here, all links have the same files, I just uploaded them to different hosts for other people's choosing...

http://www42.zippyshare.com/v/37047710/file.html
https://www.sendspace.com/file/lubcmc
More files can be provided if needed to show the problem happening on various other albums.
I really hope that people can spot this issue too and help get this fixed, I know this gapless playback feature might not be important to some people, but like I said at the start, it's an essential function for me in a music player and I use it on a daily basis when I listen to music.
Thanks for reading this long rant of mine, appreciate it.
Ger

I believe this issue occurs only between songs that iTunes has converted to a lower bitrate for you during transfer to your iOS device and songs that it has not done this for. Take this Between the Buried and Me album, for instance. I have marked all of the transitions that should have been gapless but probably aren't in red. I know for sure that most of these marked transitions are indeed broken and that the most of the transitions not marked in red work flawlessly... I honestly can't remember whether or not some of these transitions were gapless or not, but the many transitions I do remember working or not working match up exactly with whether or not the songs on either side of the transition were also on other sides of the 256kbps threshold, the threshold at which I enabled iTunes to convert tracks to 256kbps AAC.
I'm going to try re-sync'ing my library with that "feature" disabled and see if it fixes my gapless playback problem. Will post the results once I test it out.

Encoding and playback problem HD files

Hi all,
Currently, I'm using a new HD camcorder and have no problem with importing and playing these files is premiere cs4 pro. However, when I'm using six video track at the same time I experience some playback problems. After rendering, the video's play, but not smooth, they skip frames and playing a few frames back. In other words, it seems that the video playback stutters. The problem still excists when I encode the project to any file (mpeg2-blu ray, avi, etc). When using two video tracks (with two HD video) this problem is not present, even when these video's are in slowmotion. Installing the new update (4.2) did not solve the problem.
Specs of my system:
Quad core Q6600 @3.0GHz (overclocked)
8gb RAM
>200gb free disk space
windows 7, 64-bit
Does anyone have some suggestions to solve this problem? Thanks in advance.
Regards,
Jeffrey

Harm,
Sorry for not responing for a few days, but I runned the benchmark you'll send me. The main results (dee details attached file):
53,6, secs Total Benchmark Time
6,4, secs AVI Encoding Time
14,2, secs MPEG Elapsed Time
33, secs Rendering Time
Since the potential problem is my hard disk, inaddition, I runned HDtune (hopefully it will help pinpionting the problem):
disk1: avarage transfer rate: 94MB/s, acces time 13.8ms, burst rate 185MB/s
disk2: avarage transfer rate: 85MB/s, acces time 14ms, burst rate 157MB/s
disk3: avarage transfer rate: 73MB/s, acces time 13.9ms, burst rate 183MB/s
Analyzing these results, could the current hard disk configuration cause the problem I have, or is my system to slow anyway to edit AVCHD material?
If the hard disk configuration is the problem, could it be solved by applying your suggestion by removing all partitions? Since, I'm not looking forward of removing all partions(re-installing windows (dual boot win7 and vista), shifting a huge amount of data, etc), but if it would help I will do it.
Thanks inadvance,
Jeffrey

Mplayer playback problems

Hello, Mplayer video output is rather jerky and not smooth. I believe its sound related because adding '-nosound' makes the playback smooth again. I've been trying to seacrh for the solution to this for hours; any suggestions? I use OSS by the way...

Oh - lol, I had that in there temporarily as I was troubleshooting. I'm aware.

Or, if the nVidia card is new enough (some 8400 and pretty much everything newer), use VDPAU. Otherwise, nVidia chips work better with the xvmc driver than even the xv driver.
pharcyde,
From your xorg.conf file, it looks like you have an 8800GT. VDPAU works great with that card. It will solve most of your video playback problems.
Will do.
Update: Using vdpau with '-vo vdpau -vc ffh264vdpau' I can play 720p HD with only ~7% cpu usage!

How to fix iMovie 08 problems under 10.5.3

iMovie problems under Mac OS X 10.5.3 linked to color system
After updating to Mac OS X 10.5.3, users may have problems with launching iMovie. For most, iMovie refuses to opens, and the usual fix of removing the iMovie preferences, caches, and other iMovie settings files, and then relaunching the program does not appear to help. One user reinstalled the program with no luck resolving the problem:
"I have the same problem. I've tried to reinstall the imovie, but it still does not work. I have imported a lot of video in iMovie. Please help!!! "
For other users, while iMovie would start, they could not open any projects or use the program.
One user, while not initially affected by this problem, found that after changing the color calibration of his Apple Cinema display iMovie suddenly wouldnt open just as described by others; however, upon reverting to a previous color profile iMovie became functional again. This indicates the problem lies somewhere in computer's color system configuration; and changing color settings seems to have fixed the problem for all affected users.

Change the screen colors Go to the "Displays" system preferences and change the color output of the screen (either from thousands to millions, or vice versa) and relaunch iMovie. Somehow changing the display color depth modifies the color system so iMovie properly loads.
Calibrate the display While for some users calibrating the display resulted in the iMovie error, for others the problem was fixed by re-calibrating the display. Calibrating the display can be an involved process, but it is recommended to ensure your screen outputs the most accurate colors as possible. This option is available in the "Displays" system preferences under the "Color" tab.

Correcting the problem by changing profiles suggests a permissions problem which repairing permissions won't fix. Use the terminal command
ls -al /Library/ColorSync/Profiles
Compare the permissions on the working and non-working profiles. If they are different, correct the non-working instance.

Another fix for iMovie launch problems We previously reported that, after updating to Mac OS X 10.5.3, users may have problems with launching iMovie. For most, iMovie refuses to opens, and the usual fix of removing the iMovie preferences, caches, and other iMovie settings files, and then relaunching the program does not appear to help. One user reinstalled the program with no luck resolving the problem.
We noted a few fixes for the issue, including changing scren colors and calibrating the display. Now some users have reported that temporarily adjusting screen resolution can allow iMovie to properly launch. The resolution can be changed back to normal after the update.
"Neither suggested trick worked for me. However I temporarily changed the resolution to 1024x768 and then launched imovie. I then went back to my native resolution of 1280x800 (white ibook) and now imovie always launches. Thanks for the tips"

Hello MacHeads: I downloaded Handbrake 0.9.1 for Tiger, so I can upload a homemade DVD for editing in imovie. Problem is I can't even access Handbrake Help book, because I think my firewall settings are preventing me. I tried turning off all my firewall

Hello MacHeads: I downloaded Handbrake 0.9.1 for Tiger, so I can upload a homemade DVD for editing in imovie. Problem is I can't even access Handbrake Help book, because I think my firewall settings are preventing me. I tried turning off all my firewall settings.? IDK if I'm even doing that right. Can anyone help out here?

You don't need Handbrake for that if it is your own DVD.
You need to convert the VOB files in the TS-Folder of the DVD back to DV which iMovie is designed to handle.
a DVD is in a compresed format called mpeg2, which is standard across all DVDs. This is what is known as a 'final delivery format' and is not suitable for editing. Because is is compressed, a 4.7GB DVD can hold a two hour movie (dual layer DVDs twice that), whereas the DV stream from a video camera, which runs at about 13GB per hour, is not compressed and IS intended for editing.
In other words you have to 'reverse engineer' the DVD back to an uncompressed format in ordfer to edit it. There is a penalty for doing this in terms of slight quality loss, but it is one you can live with.
When you have your DVD as an icon on your desktop, double-click it, and it will open to reveal a TS-Folder containing a number of various files, some called VOB. These are the constituent parts of any video DVD.
When you have downloaded and installed mpegStreamclip, and purchased and installed the Apple mpeg2 plugin, open mpegStreamclip and drag the entire TS Folder into its window. Then using the various menus available to you (just explore them and you will get the hang of it) ask it to convert to DV.
That DV file, which will be many times larger than the original TS Folder, and which can a while to create (be patient - make coffee or prune the roses!) is what you can now import into iMovie for editing etc.
When you have finished doing that, you then have to turn the project back into a DVD.
mpegStreamclip can be downloaded from here:
http://www.apple.com/downloads/macosx/video/mpegstreamclip.html
which is free, but you must also have the Apple mpeg2 plugin :
http://www.apple.com/quicktime/mpeg2/
which is a mere $20.
Another possibility is to use DVDxDV:
http://www.dvdxdv.com/NewFolderLookSite/Products/DVDxDV.overview.htm
which costs $25.
For the benefit of others who may read this thread:
Obviously the foregoing only applies to DVDs you have made yourself, or other home-made DVDs that have been given to you. It will NOT work on copy-protected commercial DVDs, which in any case would be illegal.

This content requires HDCP for playback problem! Apple TV2

Owned Apple TV for two weeks. Two weeks ago, everything was fine for films already in my iTunes library.
This week, when selecting play on a movie, I get the message 'This content requires HDCP for playback problem' inconsistently. Some vids work, some don't. Then they do then they don't! I have tried on a Samsung TV and a Sony Bravia? Same for both!
How do I resolve this. I have tried different HDMI ports, turned Apple TV 2 off and on. Tried different cables (Although my HDMI cable is the one I purchased from Apple).
Any suggestions? Is it something Apple need to fix? This is kinda embarrassing when I tell friends how good Apple TV is, get them round to watch a movie and inconsistently get this.
Many Thanks for any help
Dave.

I too sadly have this handshaking issue. I'm in Phoenix, AZ. Day one buyer for ATV2. Worked all of about two days in terms of streaming HD content from either my MAC or netflix. About the third time i tried to stream HD content from Netflix or Blu Ray digital copies from my Mac, I get the HDCP compliance message stating my display is not authorized.
I have tried every concievable combination of unplugging and rebooting of TV (Samsung 2005 DLP), ATV2, and HDMI switcher (Monoprice) and nothing will work. My DirecTV HD-DVR works like a charm. If I rent an HD pay per view from DirecTV, no problem. If I rent an HD movie on iTunes, won't display it due to the HDCP issue. I've NOT ONCE had an issue with my DirecTV HDDVR having an HDCP compliance issue and of course its connected to my TV via HDMI thru my monoprice HDMI four port switch.
I guess the only other thing I could try is exchanging the unit itself. But everything else works as advertised. It feels like this is just a software issue that needs to be patched, and fast.

MPEG-1 playback problems

Hi all,
I've imported an MPEG-1 file of 70 minutes with the
DirectMedia Xtra (on PC) and Quicktime (for MAC), but I have a few
playback problems:
On PC it works quite well, only the slider won't go beyond a
certain point in time (about 50 minutes), fom there it always snaps
back from where you dragged it.
The sprite script for PC :
on exitframe me
if sprite(me.spritenum).movietime >=
member(sprite(me.spritenum).member).duration -1 then
go to frame 5
end if
end
On the Mac the MPEG plays very jerky, turning of the "sync to
audio" helps but then there's no audio off course. The script is
the same, except the first lines to control the Quicktime playback
on enterframe me
sprite(me.spritenum).movierate=1
end
on exitframe me
if sprite(me.spritenum).movietime >=
member(sprite(me.spritenum).member).duration -1 then
go to frame 5
end if
end
I've read that the "member.duration" script can cause a few
problems, does anyone has an alternative I can try ?
Thanks in advance,
Gerrit

Hi Gerrit,
First, any reason you're not using the MPEG Advanced Xtra
insttead of DirectMeda
Xtra? This Xtra is the followup to DirectMedia and is better
in many ways, one
being that it is cross platform so you can use the same setup
for mac and PC.
I have had jerky playback on the Mac and the issue was was
bad formatting of teh
MPEG file itself. You can read more on this at:
http://xtras.tabuleiro.com/support/technotes/mpeg_advance/ma009.htm
Best solution was to use TMPGEnc to reformat the MPEG files.
This program can be
downladed for free at:
http://www.tmpgenc.net/
It may fix the timing issue as well.

IPad 5.0.1 update video playback problems

HI is anyone else having playback problems with videos on IPad 1 after 5.0.1 update???
As in the playback not atcually working at all???

See if any of the following Videos 'fixes' work.
Try searching for the name of one of your videos on the iPad's spotlight search screen - swipe your first homescreen to the right, type in it's name, and if it finds it tap on it to see if it plays.
If that doesn't work then try closing the Videos app completely : from the home screen (i.e.not with the Videos app 'open' on-screen) double-click the home button to bring up the taskbar, then press and hold any of the apps on the taskbar for a couple of seconds or so until they start shaking, then press the '-' in the top left of the Videos app to close it, and touch any part of the screen above the taskbar so as to stop the shaking and close the taskbar.
A third option if the two above don't work is a reset : press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.

Why am I having imbedded video playback problems in Lion?

Hello all,
I'm been having problems viewing web videos on my 2011 MBPro 13'' w/ OS X Lion. Any time of web video I have normal sound by the video frames get all jumpy, almost like its less than 1fps. The only web videos that do not have this problem is when I watch a youtube video on youtube.com. If I watch imbedded youtube videos, I have the same skittish video playback problem.
I have my adobe flash updated and I used Google Chrome as my web browser.
Anyone else have a similar problem? Fixes? Thanks!
-Sean

Two things to keep in mind
There is a forum for Lion, another for MBP owners, and this is not.
And yes you will find lots and lots of threads of same.... no one looks at those that were "Solved"
