FCP stalling on playback

I installed a couple software updates last night (through software update) and ever since, when I play back my timeline, I get the spinning rainbow for about 30 seconds.
Unfortunately I do not have a disk image that I can roll back to. Any suggestions?

I'm pretty sure its related to the "Compatibility Update for QuickTime 7.5.5" that was released on 11/17. This was 1 of 2 updates that I installed yesterday.

My apple tv stalls during playback. How can I fix this?

My Apple TV stalls during playback. I am hooked up through ethernet so I'm certain that it is not a network issue. What happens is that after a few minutes of normal playback the movie that I'm watching simply stalls. It looks like AppleTV is trying to reboot it. if I rewind it briefly and restart the movie by pushing play it seems to be fine. But it it stalls again after a few minutes. I have to do this very often and it becomes quite distracting when you're trying to watch a show.
One thing I have noticed is that if I pause the program before it stalls and leave it for about 15 minutes I can watch a large portion of the show uninterrupted.
The files are in my iTunes library. I don't seem to have this issue if I'm playing the files from my iPad via AirPlay. I have restarted, reset, and rebooted AppleTV several times and it still keeps doing it. Any suggestions out there?

640 x 480
Widescreen 16:9
These settings are contradictory. Please post a screen capture image of the QT "Inspector" window to confirm what encode matrix setting, PAR display setting, and Scale display settings are actually embedded in your file. Also please confirm whether or not the source material was widescreen and it is 4:3 aspect you wish to correct at this point. If not, then please state the height at which the transcoded file was encoded and the target aspect ratio at which you want files to play in all media players.
Once compressed it plays back in Windows Media Player as 16:9 video.
When played back with Quicktime it is squished into a 4:3 format.
Different players dispay content aspect differently.
Why is this happening and how can I fix it?
QT 7, for instance, displays the file using specific Scale dimensions and if these dimensions are not equivalent to PAR/anamorphic playback settings, then the file can display differently in differently media players. As to fixing the problem, that depends on which setting you are trying to fix and what platform/software is available.

FCP Real Time Playback

I want to do real time playback of a FCP project from my MacBook Pro, and it appears my new Matrox MX02 Mini box will allow an HDMI output of my 720p60 project from the MacBook Pro. Pretty cool. What are your best suggestions for encoding a reliable playback product? Compress to an MPG2 program stream? Make an HD Quicktime? Or....? Bye bye 480 DVD's!

David, if I could ask your setup for a QT playback out of the DVI port on the MacBook Pro:
1) You take the DVI output into a DVI monitor, or do you use a DVI-to-HDMI cable?
2) Audio is from the quarter-inch jack on the MacBook Pro?
3) Can you achieve good 720p?

FCP can't playback HDV

When I set my FCP video playback settings to AJA KONA 1080i25fps, the playback on the sequence plays for a few seconds and then pauses. In fact any AJA playback setting is choppy. However, when I playback with video settings None...there is no problem. I need to output to tape immediately. Anyone have a solution to this? Thank you

AJA has an amazing technical support team and this is a question for them.
Good Luck

FCP stalls at Restoring the Window layout

Hey all,
FCP doesn't seem to want to open and stalls constantly on "Restoring the Window Layout"
I've tried Final Cut Pro X: May stop responding at "Restoring the window layout" or open to a gray window - Apple Support but that doesn't help at all.
I've tried reinstalling the whole programme. That doesn't help at all.
in my Force Quit Applications box I'm getting a notification that com.apple.audio.InfoHelper is not responding
Anyone got any ideas? Or do I just put this down to Apple's new definition of what a "professional" application is?
Thanks
Sam

OK
Trashed ~/Library/Application Support/Final Cut Pro/Layouts - quit, restarted, no change
Trashed ~/Library/Preferences/ anything with com.apple.finalcut in the title - restarted and it now works.
Hoping it lasts longer than the first time it "worked"
Thanks for the help
Sam

FCP 6 No Playback

Hello,
I have just upgraded to FCP 6 and I am no longer able to play back in real time. I have external video enabled and when I refresh nothing happens. However, when I select "show current frame" the monitor does update that frame, but during playback in the timeline or scrubbing in the timeline there is no playback. I am using an Aurora Igniter Breakout Box if that helps.
Thanks

Yeah I already have it set to display all frames and my device is being read and is selected but for some reason when I actually play back I get nothing but the default color bar output for the igniter.

ITunes 10 stalls on playback with Library on USB (2 and 3), OS X 10.8.2 2.6 GHz intel i7, MP3 320 kbps, playback is fine using internal SSD...

All this power in a brand new mac-mini.. and iTunes is constantly stalling playback every 1 - 5 minutes (only when the iTunes Library is on external drives)..
(1 - 3 second silence interrupting playback then continuing...)
iTunes 10.7 (21) 64-bit
I'd prefer to keep my MP3 Library on USB 3.. and preserve the smaller internal SSD drive for other activity...
Is there an Apple certified technique to prevent disk spin down ?
Energy Saver control panel indicates that "Put hard disks to sleep when possible..." is unchecked..
Maybe iTunes could simply buffer larger sizes of the file, or the whole file.
(I have enough RAM to hold my entire 3 gig Library..)
(if the stall occurred only in between songs that would be acceptable)
Can we get an iTunes patch for this ???

Came across this article:
http://d43.me/blog/413/slow-startup-and-sleep-problems-on-macbook-pro-22/
Removed the 5 IOFirewire files removed from System/Library/Extensions and rebooted. Startup up within seconds!
Haven't used the firewire in a while, but I don't recall having any issues with it previously.
This worked, so I'm happy. Hopefully it sticks.

FCP External Video Playback problem with HDV

Hey all. I just got the Canon HV30 HD camcorder and it is excellent. I am able to import the HDV footage to FCP no problem. I'm recording in 24p mode by the way.
I can't seem to get playback from the timeline back to the Canon so I can see the edited footage on the Camcorder's LCD screen. I've tried everything. All the settings seem to be grayed out. How am I suppose to get my edited footage from the computer back to tape? Help is much appreciated!
Greekappi

I'm not the person at our facility that does this, but we do it all the time. However we are using the Sony HDV decks, 25U or something like that.
I have also seen the stuttering video you described, I'm not sure why it does this on some projects and not others, it is very random. When it does stutter I render out a complete self contained Quicktime and then print to tape from that. However, I occasionally still have this problem with that? But it does seem to help more often than not.

FCP stalls on startup when loading pluggo audio plug-ins

FCP 5.03 consitently stalls ( i have to manually quit) on startup. I can see that it is loading pluggo audio plugins when this happens. (usually the pluggo bus send plugin) If i temporarily remove the pluggo component from the au plugin folder it starts up ok. another computer i use has pluggo installed and it starts up fine. any advice?
thanks
rocky

I don't worry about it - as long everything finds what it needs and there's no conflicts.
I think once Peak asked me for the location of one of the filters I'd moved - I pointed it to it, then it was happy.
As long as fcp is stable, I'm happy.

My Hp A6750Y DVD player stalls in playback of DVD movies -

A6750Y HP DVD player stalls when playing video back. Sound is fine. Have upgraded HP media smart, still problem. Have tired to update drifver but have not been able to .

Hi,
What your seeing regarding the Driver for your CD/DVD Drive is normal. The driver for these devices is supplied by Windows and there is no update. Here's a screenshot of the driver tab from my Bluray drive - as you can see, it's dated the same as yours.

Final Cut stalling on playback

None of my clips will preview in viewer or canvas, they stop about 15 seconds in and the little twirling ball starts spinning. First I was working with AVCHD then I converted then to DV and it is still happening. I even wiped the system and re-installed FCP. I'm using the stock graphics card NVIDIA G Force 7300 GT.
My problems sound similar to the people with MacBook having a problem with firmware 1.7, but I'm on a Mac Pro?
If anyone knows if my problem is software, hardware, or operator please let me know.

Delete preferences to force FCP to run RT Profiling at the next launch. Note that this will also reset your Scratch Disk.
Deleting FCP Preferences:
Open a Finder window. Set the view mode to columns:
Click the house icon that has your name next to it.
Click the folder "Library" in the next column.
Find and click the folder "Preferences" in the next column.
Find and click the folder "Final Cut Pro User Data" in the next column.
Move the files "Final Cut Pro 6.0 Prefs", "Final Cut Pro Obj Cache" and "Final Cut Pro Prof Cache" to the Trash and empty it.
When you have a stable set of preference files, download [Preference Manager|http://www.digitalrebellion.com/pref_man.htm] to back them up.

FCP and QT Playback

I just installed FCP 7 and started my first project (DV NTSC). Footage was shot with a DVX 100B.
The clips really look bad in both Viewer and Canvass - lots of stair-stepping, raggedy text, and soft. I don't have a separate monitor and I know I shouldn't jump to conclusions about image quality based on what is displayed in FCP, but these results were unusual compared to FCP 6.
I exported a short test and opened it in QT 7 and it still looked awful. I then opened the same file in QT 10 and it looked perfectly clean. I then brought the file into Compressor and transcoded it to ProRes. When I opened the ProRes file, it looked great in both versions of QT.
Can someone help me figure out what's going on?
Thanks.
Russ

Thanks, David.
I agree that I shouldn't expect much from the canvass. It is what I see in the viewer that concerns me…all those artifacts.
The fact that it looks great when I open a clip directly in QT 10, but continue to look poor in QT 7 only adds to the puzzle.
What I'm describing is all taking place on a 27 in iMac display, by the way.

Movies stalling on playback

I have a large library of movies in iTunes all stored on a NAS which until now has worked perfectly but I have just tried to watch a film and after a few minutes it started to stutter then stalled altogether. I have tried several different movies all with the same result, all of which I have watched before without a problem.
I have run check disc on the NAS and nothing was found, the NAS is only about 50% full so lots of space.
Any ideas anyone.

I'm pretty sure its related to the "Compatibility Update for QuickTime 7.5.5" that was released on 11/17. This was 1 of 2 updates that I installed yesterday.

FCP crashes when capturing uncompressed video/drops frames on playback

I have just started using FCP 6 but had similar problems with 5. FCP seems to work fine with lower data rate captures and playback like DV25. When I try to capture uncompressed 8 or 10 bit SD or HD it will capture for a while then eventually crash. Shorter captures of 20 or so minutes will work ok but then the video will drop frames and stall on playback. It will suggest lowering real time audio tracks, changing the RT settings etc., but it is only a 2 audio track capture with video and RT is already set to dynamic. I have successfully done this before so I know the hardware is capable, I have captured and played back 1.5 hours of continuous 10 bit uncompressed SD without incident. The system hasn't had a lot of other stuff installed on it. It seems like there must be some sort of software conflict.

I am capturing to a Ciprico dual channel U320 array attached to a ATTO UL4D SCSI controller. I don't use the system for these data intensive captures all that often and sometimes I have no problem at all and other times I do. I noticed that the raw movies would play in the quicktime player ok without stalling or dropping frames so the issue seems to be with final cut. The last time I had this problem was with playing back 720p DVCProHD files and it would only play for a few minutes and then give a error message about dropping frames and suggesting lowering the number of audio tracks and changing the RT settings. I am thinking there must be a software conflict. We just installed FCP 6 and this was the first capture I did with it and had the same old problem right off the bat.

Frame Offset Playback Control in FCP HD Not Working

if I output my audio via firewire, it works just fine. However, I am unable to playback audio in sync via built-in audio (which sounds far better than my firewire output device).
I've gone to to my FCP System Preferences; Playback Control and it has a default offset of 4 frames. But it's still out of sync. However, if I manually offset my audio in the timeline by 4 frames, it's IN sync. I've tried various frame rates in the Playback and it never syncs, in fact it appears as though nothing is changing, no matter what I set it at.
What am I overlooking or doing wrong? It just doesn't make sense.

I'm having the same problem on capture. I'm migrating from a PowerBook 800 to an Intel Imac. I need the Keyspan Serial to USB adapter to run the 422 port on my BetaCam player. I finally got it hooked up tonight.
I grabbed a piece of video, and I'm getting two error's. First, like you, I'm 4 frames off (I'm using a Window Dub so I see the offset). Secondly, when I stop the capture I get a window telling me there is some discrepancy with my captured audio rate. When I look at the setting for the clip, all the frame rates seem to match. When I check the video, the lip sync is indeed off.
So I'm using the same Keyspan adapter I've bee using using in Panther. Now I'm in Tiger, and I have what seems to be the latest, Intel Mac Keyspan update.
But when I type in an offset number. and hit return, it doesn't "take". There is no change on the offset if I do another capture, and when I go back to the setting, it is at zero. I remember in Panther the current offset number was always visible.
Any suggestions? I'm trying to get the offset to take, so I can capture proper time code on this BetaCam dub.
Thanks.
