T. what you are showing is how I would expect it to work, but when I select multiple audio clips and a single video clip and synchronize, I only get the reference stereo and one of the audio clips included in the newly generated synchronized clip.

Thanks for the pointers, but… I’ve analyzed the audio and removed the silent channels and I still have this problem.

Creating a multi-cam clip does work though, but I really thought that I would not need to go there, it seemed “wrong” to me.

I’m not sure whether the channel configuration has something to do with it. The video clip is obviously a stereo (with the guide tracks), but the externally recorded audio tracks are three separate mono channels.

I did a search on the Apple support forums, and I found an identical problem with someone having the identical setup as me – stereo guide tracks on the video and 3 mono channels.

This is such a stock standard configuration, I’m scratching my head as to why this is not working.

I’m glad it’s running well. You’re marginally over the power specs for the machine. The 5,1 can support a max of 300W for PCIe, the 5870 runs 188W and the 4800 runs 150W. I hope you don’t have Apple Care, they might invalidate your coverage based on your setup. Thanks for your answer on the power connectors. I hope your rig continues to give you no problems.

Nice rig. Where are you getting the additional power from? I thought the 5,1 only had 2 additional power connectors for PCIe cards and the 5870 uses both?

Cheers,
