Ken Burns Crashes FCP X

I am currently on 10.0.7 of FCP X.  I have noticed this bug since the last release, but not prior to that.  This occurs on my MacBook Pro (2.2 GHz Intel Core i7 running MacOS 10.6.8) and also on my 11" MacBook Air.

 

Basically, a third of the time that I add in a Ken Burns effect, the program crashes as soon as I go to adjust the START/END boxes.  The effect will still run as long as I don't touch the default positions of the boxes.  Once this occurs, I can not edit KB on that image, no matter how many times I restart FCP or the computer. 

 

This is a relatively new issue to me that hasn't gone away.  I have seen a prior thread from a year ago on this topic (https://discussions.apple.com/thread/3707812) but the suggestions all point to a user file size issue which I don't think is the case here.  It is clearly a FCP bug that perhaps the Mac application development folks don't see on the combination of hardware/OS that they are using.

 

Any thoughts on this?  Does anyone else see this bug?

 

Thanks in advance for any tips,

 

-Todd

    Please give complete and exact information on the specifications of this media. It's not a readily reproducible problem.

    USB2?

     

    The Air uses integrated graphics I believe, which limits its effectiveness with FCP. It could be a combination of factor.

    I have exactly the same problem as toddjb. 

    FCPX 10.0.6

    OS 10.7.5

    FCPX libraries reside on USB 3.0 drive (less than 50% full) running through USB 2 hub

    Pictures are either D800 or Sony Nex 5N processed in Aperture and drug over to FCPX to where I want them.  Files are JPEG in the range of 4300x3500 pixels.

     

    Almost 100% of the time, whenever I click on the start/end of the Ken Burns, FCPX crashes.

    I should have added

    iMac with 3.4 GHz Intel Core i7

    16 GB 1333 MHz DDR3

    AMD Radeon HD 6970M 2048

    The USB hub is choking down the speed. The files are larger than they need to be. I assume the files are 8-bit RGB.

    Files are 8-bit RGB.  Project needs to remain mobile until complete so it needs to sit on an external mobile drive.  Picture file size is pretty standard in the photography industry so I would consider this to be a serious weakness in FCPX. 

     

    I believe the same phenomena has happened on projects run off my Thunderbolt drive (but I don't have a direct quantitative comparison).

     

    I am curious as to the evidence or data which supports your suggestion?

    What suggestion?

    That the source of the crashing is related to the USB or picture file size.

    I would add to the symptoms that if I apply the Ken Burns effect but DO NOT CLICK the start/end boxes, it seems to work fine.  There is something going on during the click/selection process.

    I don't think the USB is a cause of the problem. I'm just pointing out that it's a poor idea to run a fast USB3 drive through a slow hub.

     

    The image size can be a problem. It's much larger than standard video formats. If you have a great many files loaded in a project like this they have to all be held in RAM while the application processes them. The Ken Burns effect and its preview is processed entirely in the graphics card and held in RAM.

     

    You should also look at how the image is procssed in Aperture. You might want to check what settings you have in Aperture for the image previews.

     

    Would it be possible to post a few of these large images somewhere so I could try to reproduce the problem? Currently the effect doesn't produce the result you're getting with my media.

    You have some sleuthing to do. Edit the pic down in size and see if that cures it. Buy or borrow another drive if possible or put the file on your local HD and see if that helps. Do one at a time.  It is a pretty large file for use in FCPx but I also would agree that FCPx -should- handle it, but there's still a lot that FCPx doesn't do so I treat it like it's late beta. If you take the position that it -should- work you may never GET it to work so I'd start doing some investigation and see if you can bring an answer of your own back to the forum.

    I do understand the constrainst of USB 2 and I keep hoping there will be a thunderbolt--usb 3.0 hub or an Apple Display Device that supports USB 3.0.  But I digress..

     

    Tom... do you use dropbox and can I use your info email address to share a folder with you?

    I use Dropbox though I loathe its software. The images should be too large for email.
