Skipping problems when 2nd audio is added

I have a problem of movies skipping and long beachball delays when adding transitions etc. if I have two audio tracks installed.
This even happens on small 15min. movies, but only when I add a second audio track.
All is normal until I add an audio track and at the point when the track starts to play.
I did not experience this with iMovie5 or before.
I have 1gb ram with 18gb free on system disk and working from external 500gb Lacie FW800.
The two 512mb memory sticks are Apple and system profiler says all is OK.
I repair permissions twice a week, run Disk Warrier once a week and Tech Tools every two weeks.
My OSX system is always current.
example:
I start movies with about 15min. clips & photos. All is well.
When video is done then I add music from iTunes. When the movie arrives at the music it begins to skip and jump.
Also, if I add a transition it takes about 12 to 20 seconds to finish while I watch the ball.
I have cleared the system of all active applications just to see if ram is being used meaning I might need more than 1gb.
Doesn't matter if I have 0 or 5 active in the background ... same problem
When I finally get a project done and burn to DVD it plays just fine without skips.

I need to clarify my initial description when I used the term "skips".
In reality I am experiencing pauses.
The movie does not skip to another location, but rather pauses both video and audio during play on iMovie only.
It takes a very long time to edit just 20 min. due to this problem.
The burn is just fine.

Mouse skipping problem when external display connnected

I recently purchased a Macbook, and I connect it to a Dell 3008 display using the mini DisplayPort to dual-link DVI adaptor. My issue is that when the Dell is connected and in use, the mouse pointer skips across the screen when I move it, like something is interrupting the input for a very brief period, and it's being interpolated wrongly when the input comes back.
The problem doesn't occur when the external display is disconnected, and it happens with wired USB, wireless USB and wireless Bluetooth mice.
No adjustment of mouse sensitivity options seems to fix it, and the interruption in the pointer movement seems to happen at semi regular intervals of between 5 and 10 seconds apart, although I can't be 100% sure.
Interestingly, it doesn't happen when I connect a lower resolution external display using the same adaptor. So it only happens at 2560x1600. I'm wondering if it's a problem with a hardware accelerated mouse cursor and the NVIDIA graphics driver.
Anyway, it's a real barrier to me using the Macbook, so hopefully someone has a solution.
Thanks!

Same problem here: wireless MS Laser Mouse 6000, either a samsung or LG external display connected via mini adaptor. Have the MS intellipoint drivers installed. It began to happen about a fortnight ago, and seemed to coincide with the Java update 4/Bluetooth Firmware/ Safari update applied on 24/6. This may have been around the time I changed display preference to 'best performance', so could well be a graphics driver issue?
In my case, it tends to happen in certain spots on the screen, and the likelihood of a skip seems to depends on the speed I'm moving the pointer. Faster = more likely.
It's messing up my tanking in warcraft something terrible.

Logic 9 - problem when cutting audio.

Hi guys.
First of all welcome on forum.This is my first post.
My main problem is when I cutting audio files -
audio meter is jumping up to maximum and speakers generate loud click.
Also another problem, very popular on Logic -
"Disk is too slow or system overload".
Please see my movie which show the problem.

Please help me.
Thank you.

hi buddy,
thank you for your advice but unfortunately it doesn't work
A lot of problems with Logic here.

I've paid 4800 $ for my Mac Pro and it cant even cut one sample or
play two loops correctly.
I have big HEADACHE and dont know how to resolve this problems.
I have to say after 15 years experience that PC make me less troubles

What a bad story.

ITunes Problem when importing Audio CDs

Since I updated my macbook pro a fortnight ago, I have been having trouble importing audio cds into iTunes.
When I insert an audio cd into my superdrive, iTunes opens as normal. I receive a pop-up message that asks if I want to import the contents of the audio cd. I click "Yes" and the audio cd icon immediately disappears from the iTunes devices list.
I then have to eject the audio cd, re-insert into the superdrive, and I receive the same message in iTunes again. I am able to successfully import the cd the next time.
When initially importing the cd, if I select "No" when asked if I want to import the cd, I can then select all of the tracks in the Audio cd device list and then I can select "create mp3 version".
I tried the same procedure on my wife's macbook pro, and iTunes simply freezes and won't proceed. We both updated our macbook pros about the same time.
If anyone can please offer any insight into this problem, please let me know. I would be most grateful for anyone's help with this issue.
Respectfully,
PugetSounder

No insight I'm afraid, but I have exactly the same problem as the first one you describe. I don't think it happens every time, but most times the first insertion of the CD is as you describe - iTunes asks if I want to import, I click "Yes", and the CD disappears from the left hand column in the iTunes display. When I eject and re-insert, it always works. This must be a bug in iTunes. Can anyone explain it? This is on a MacBook using the latest software - but I don't think there has been an update in the last month (maybe I just forgot).

Problem when exporting audio from Premiere Pro v4.2.1 into wave 5.1 format

Hello to Adobe experts!
After installing of last updates for Adobe Premiere Pro (v4.2.1) and for Media Encoder (v4.2.0.006) the was a problem:
Now I cannot to export audio from adobe sequence into uncompressed wave format with 5.1 channels settings. Source m2ts video files in sequence are with 5.1 audio.
What I doing:
1) in Premiere I execute "File\Export\Media"
2) Export settings are:
- format: Windows Waveform
- audio codec: Ucompressed
- basic audio settings: 44100Hz, Channels: 5.1, Sample Type 16bit
3) After OK button it opens Adobe Media Encoder.
4) After pressing Start Queue in Adobe Media Encoder there is a message "Error compiling movie. Unknown error"
In earlier versions it worked fine.
Can you help me with this problem?

Here are the options, from a sequence with 5.1 master track:
and with Surcode:
Notice that first one does only give stereo as an option. Nothing more. With Surcode it gives you 5.1 sound.

Problem when form is dynamically added in a tab page

Following is the requirement:

=> On click of a button,
1. I created a Control object.
2. I created a Form object.
3. Initialize the Form Object.
4. Initialize the Control object and add it under the Form Object.
5. Initialize the TextBox object and add it under Control. (Keep some multiline text in the textBox and make it Multiline)
6. Set form.TopLevel = False
7. form.Show
8. form.Parent = TabPage.
=> When i run the above application/form, the focusing works wierdly in the textBox. I am not able to guess what the issue is.
Any help will be appriciated. :)

I don't know what initializing a control object and adding it under a formm object means. Or what initializing a textbox and adding it under control means.
Rather than setting a Forms parent as a tabpage somehow set the Form so toplevel = false and add the Form to a tab pages controls.
Even this is a poor way to do business. There's also such a thing as
MDI Forms. Although if you want controls on a Form then why not use controls with it? What would be a reason for creating separate Forms to place inside of tabpages? It sounds not well thought out design wise.

Skipping Problem when vieweing Flash Videos

Hi.
I've downloaded and istalled the latest flash plugin, but
videos on sites like youtube and google videos skip every few
seconds. It's really, really annoying.
I'm running XP on a 1.0 Ghz Athlon (not Athlon 64, just
Athlon). Have about 320 mb ram. Also have this Riva TNT2 32mb video
card.
I've tried to watch videos on both Firefox 2 and Internet
Explorer 7, but both are the same. When I download flash videos
though, and play them through VLC player or something like that, I
don't get any skips. It's just for online videos.
No, it's not about loading the videos either. Even if I wait
until the video's fully loaded, The skipping's still there. And no,
nothing's running in the background as I play the videos.
I've also tried to uninstall the plugin via the "flash
uninstaller" downloaded from adobe, reboot, reinstall the plugin,
reboot. No Dice. Also tried running a few antispyware programs.
Still skips.
I've tried turning off the windows firewall, and tried
without any other anti-virus or firewall running, and still get
skips.
It's as if the video's refreshing every 3-6 seconds...
Please help
Edit:
Just tried downloading Opera for the hell of it and trying to
watch videos on it, but still get skips. Also tried firefox's safe
mode (no plugins).

Hi 9000,
Have you verified flash is up to date? If it's not up to date, have you considered downloading & the latest flash player?
While your at it, you may want to verify that Adobe ShockWave is up to date. And if it's not, download and install the latest 64-bit shockwave player.
If your still having issues, have you tried using another account on your dad's computer? dose it have the same issue?
if it's only your dad's account that has issues, you may want to try deleting flash cookies by using a program like Flush.app – Flash Cookie Removal Tool For OS X.
cheers,

Logic Pro 7.2.3 - Pitch problem when opening audio from GarageBand 2.0.2.

Hi, I'm opening up a GarageBand file into Logic 7.2.3. All the synths open perfectly. However, the audio is pitched down as if it was recorded at a different resolution. I run Logic and GB in 44.1k, so I'm stumped. From the arrange window, if I double-click on the file and check it in the audio window that pops up, it plays back at the correct pitch. Any ideas what's going on?
Thanks!
Armen

I figured it out but thought I'd post the answer here in case others were having the same issue. I noticed to the upper left-hand corner of the arrange window that "Follow Tempo" box was checked. I unchecked it and the pitch is now correct.
The file default on my system opens up with the box checked .

Car bluetooth problem when a audio lead is also connected.

I noticed a strange bug today. Bluetooth works well for me in my 2008 Ford Smax with my Z10. However, if I plug a lead into the headphone jack to get music through the car speakers, when I receive or make a call the sound seems to route to the handset and not Bluetooth. I have to manually select the correct input from the menu.
The default whenever a Bluetooth phone connection is made should always be Bluetooth, It is on Android and iOS.
It is fine if no headset is connected.
Could this be looked at and fixed in a future update please.
Thanks

Yup, same issue.
I have to disconnect the lead from the phone before answering a call. Somewhat hard sometimes when driving...

Audigy 2ZS Platinum Pro in Vista x64: "Skipping" (Distortion) when record

Hi! I've just setup Vista x64 and installed the latest Drivers for my Audigy 2ZS Platinum Pro. Besides the fact that there's no software available for convenient control of the features of my soundcard (Surround Mixer, Speaker Settings, THX Console etc.), everything is fine for playback (after adjusting the bass and treble-sliders to their 0dB-Position!). But I've got a massive problem when recording audio, or when using the microphone: I can play back sound from any source without distortion, but when recording it or using the microphone for VoIP-Applications like Skype, Teamspeak or In-game communication, I get a constant "skipping" distortion like the clicking when a CD is defective and skips.
It sounds like short disruptions which come at regular, very short intervals (approx. 0 per second or so). This effect is always present, irrespective of the load situation of the system and does not change with it. In XP32, my Audigy 2ZS still works like a charme. Furthermore, I've got a "PCI Input Device" in Device Manager with a question mark, although the Firewire-Port does work. Could this be the Gameport not beeing recognised But that's not nearly as problematic as the flaw from above... Thanks in advance for your advice!

I'd like to also add that I have been observing this same problem for quite some time now. While I do not frequently have a need to record, that is changing now and I would rather not have to reboot to Windows XP in order to have functional recording capabilities.
I am currently running a dual-boot configuration of Windows XP/SP2 and Windows Vista Ultimate 64-Bit/SP, with the Audigy 2 ZS Platinum soundcard, and the latest drivers available for the card as of today's date (0/7/2008).
A clip of audio to illustrate the problem may be heard by saving and playing the MP3 file found at http://ambress.com/audigy/audio_recording_fault.mp3. The following graphic also illustrates how the sound is like a series of recorded pulses, making recording completely useless.
I would greatly appreciate any feedback confirming this problem by Creative and what solution is available or when one is to be expected. If a solution is known by any users that perhaps I have missed in searching the forum, of course I'd be grateful for that help as well.
Thank you,
Daryl

Trying to get my fcp project to burn to dvd at the highest quality? Ive used compressor and then tried to put it in dvdsp put its not working. I am having problems with the audio or when i burn it , i cant play the dvd? any help would be appreciated

Ive used compressor and then tried to put it in dvdsp put its not working. I am having problems with the audio or when i burn it , i cant play the dvd? any help would be appreciated

I suspect you are attempting to burn an HD DVD, which will not play on a DVD player...
But if you provide more details such as the settings you are applying in Compressor, then we would be able to provide you more accurate information.
How are you adding the files to Compressor?
In FCP, what are your footage properties (command-9) and sequence settings (command-0)

Problems when adding iTunes to iMovie project

I recently recorded onto miniDV tape about 15 minutes of rare color film footage from 1938-40, courtesy of the University of Missouri archives. Using iMovie 6.0.1, I made about 15 clips, divided by subject and year and added some titles. I placed them into the clip viewer and previewed the movie. No problems when I previewed it. I also "unchecked" the ambient audio, because the film was silent and the only sound was the sound of the film projector picked up by the Sony TRV-30 digital camcorder. Via the Internet, I found the top songs of the those years and downloaded them from iTunes. I "clicked and dragged" the songs from iTunes into the sound track of the project. Here's where the problem arose. After I added the music, I previewed the movie. The music track played OK, but the video image was extremely "jerky;" in other words, it would appear to stop momentarily, then "jerk" to a start again. It appears that way through the entire project. Any ideas as to why it would be doing this?
Also, I have another "mystery." The icon for the project is in the "movies" folder. The icon appears as a white "one-dimentional square" with "sideways Vs" a the top and a black star on a white field on the face of the icon. When I click on the icon, the project opens (clips etc.). In previous projects, there is a two-dimentional folder with a blue front and when you open it, there are other sub-folders in it (a "media" folder" and the .mov file etc). Why does my current movie only give me the option of opening the project, and does not show the media folder and .mov file? As always, your assistance is very much appreciated. This forum has been very helpful to me in the past. --Scooper

Hi scooper,
... An answered the second part, I give a try to part one:
* is the project located on your Mac's local drive or external?
* is the iTunes library on the Mac's local drive or external?
* is the "internet" (<<woohoo, bad kharma;-) ) music coded as aac, mp3 or aiff? or, something different, internet "standard", as ogg, wav, whatever?
your Mac/iM tries to playback in realtime (sure, that makes sense with a movie...), but obviously has too much to do encoding the music...
in case you own QTpro or a designated audio-app (Garageband, Audacity), try to convert the internet music (<<woohoo, bad kharma... ah, said that) BEFORE import to iM into aiff...
in case of usage of external harddrives:
make sure, the drive is "MacOsExtended" formatted, not FAT32... use Disk Utility to accomplish that (any reformatting erases all content!)
pay the artists//respect local laws//get good kharma

2nd audio track at 12-bit lost when importing into FCE?

I have got some DV-tapes with finalised movies which I would like to import into FCE for a) applying some enhancements and b) then burning them onto DVD. These movies once were created with FCE but after they had been exported to DV-tape (in 12-bit manner) some additional audio was added, directly via camcorder. The issue which I have got now is that although I can easily re-import these movies into FCE, the additional audio does not appear in FCE. Also, when directly checking the imported files in FCE's Capture Scratch by using the Quicktime Player the additional audio is not there.
I tried importing into iMovie and here (as opposed to FCE) the complete audio is available, both the audio originally composed via FCE and the additional audio which has been added afterwards via camcorder. Unfortunately iMovie will crash multiple times at importing due to the large number of individual clips, btw this is the reason why I once had to give up working with iMovie and bought FCE.
Anybody has an idea how I can import into FCE the movies along with the entire audio, or is this a weak point in FCE? In case of the latter, anybody has an idea for a workaround?

"Do you have an idea how to fumble out the 2nd audio pair at a Sony TVR900 i.e. how to proceed corresponding to your advice "configure the camera to ouput the second stereo pair to another DV camera with it's audio set to match the existing"? Or did I misunderstand your advice? The user manual of the Sony camcorder is ridiculously poor.."
The user manual of course is the best (should be) place to go for info on how to operate your camera. Might be one of those direct to English translations.
My idea is to use a camera that can access the 2nd stereo pair seperately. Then dub to another camera. Usually this is done via a switch or menu system.
That's where that camera manual comes (should) in handy. Also, some cameras allow you to MIX the four tracks, if this feature is available, you could dub the MIXED audio (all four tracks) to another camera.
"e.g. iMovie (provided it does not crash)? Because then I could capture the missing audio pair 2 like that in a separated manner and import it into FCE?"
iMovie to FCE is not my first choice as the importing is accompanied with quirks of all sorts, the audio is multiplexed with the video, the audio will always need to be rendered as well. Use it as a last resort IMO.
I have have heard of third party applications that can do this job, sorry, can't recall the details.

PowerBook Audio Skipping Problem
