Kernel panic rendering AVCHD footage in Encore CS5 or CS6

Mar 21, 2013 11:01 AM

I have an early 2008 Mac Pro running CS6 and 10.8.2. My usual workflow is burning two hour multi-cam live performances to DVD. Usually this is two cameras of DV, one camera of AVCHD, all in a DV timeline.

 

Lately I've been trying to burn DV timelines of nothing but AVCHD footage, and somewhere through the rendering process I always get a kernel panic. This happens with different projects, footage from different cameras (I'm using a Panasonic AG-AC130 or HMC40), whether I'm using Encore CS5 or CS6. The projects never finish. It seems to get 50-75% through rendering video before crashing. Rendering these projects on my MacBook Pro work just fine (though much slower). Timelines where it's not 100% AVCHD are still working fine.

 

I had began having kernel panics unrelated to Encore, but traced this back to a heat issue. It's an old machine after all. After installing smcFanControl, this problem has gone away. I don't normally burn timelines of nothing but AVCHD, but I'm certain there was a time in the past I was able to burn these without issue. I monitor my system temperature during rendering and I'm somewhat confident that's not what's crashing the system.

 

The top part of my latest crash report is listed below. Can anyone help me figure out what's going on?

    somewhere through the rendering process I always get a kernel panic.

    What is the "rendering process"? Are you transcoding in Encore? Is this the Encore build?

     

    If you are letting Encore do the transcode as part of the build, use "transcode now" to see if it is the transcode or a later part of the build process.

    This suggests it is a dynamic link issue. As an alternative, that most users prefer for HD to SD exports, Export MPEG2-DVD from Premiere and bring this into Encore.

    Yes, the "automatic" setting is very nice. A large percentage of the DL problems reported involve HD to SD downrezzing.

     

    You describe a difference in workflow where the older projects were mixed types (SD/HD?), and I assume were in SD sequences. Are the new ones HD sequences in PR?

     

    I agree all of these options should work.

    I think that is good troubleshooting. Are you saying that it is the exact same sequence, but with only the one camera selected? I'd look for a gap - audio or video.

     

    Did the direct export succeed? Yes, a failure there would point to a problem in the sequence.

    Is there something about that sequence that does not like changing the cameras. As next test, I would just set up the pure HD cam in the same sequence presets and see if that exports.

    After a not-too-intense Bing search, the particular panic you're getting seems to be an indication of:

    1. Your Mac Pro is dying.
    2. Bad drivers in combo with an unforgiving OS.

     

    I don't have any easy advice for number 1.  If it is still a heat issue, you may need to redo the thermal paste on the CPU and blow the dust out of the heat sink.  If it's a deeper problem than that, some serious repair work up to and including replacement may be required.  Either way, it will be a painful fix.  For number 2, try updating your graphics card drivers (which card do you have?) and/or going back to 10.6.x or Lion 10.7.x and see if things improve.

    EDIT: Although Encore and Premiere Pro have their share of bugs, a lot of times they expose weaknesses in a system because of how much they tax all of the hardware and software.

    I entered the phrase, "CPU(s) failed to respond to interrupts, unresponsive CPU bitmap" (without quotes) into a Bing search and it was an Apple-related hit on the first page that initially mentioned it.  I found other users on pages 2 and/or 3 that also had critical hardware problems.  Several more had driver issues causing the error.
