BTW for speed I’m using a Quick Cluster (7 cores) in Compressor.

The AAC sound opens in a separate Quicktime player than the H264 Quicktime player for me.

H264 has sound disabled – need a way of getting that good AAC audio onto the H264 file in the Quicktime player.

Any quick tips would be really appreciated.

All the best

Got my H264 created successfully and it looks great but the audio ‘clicks’ for me every couple of seconds.

To play the file H264 file I had highlighted both the H264 file and the AAC 128Kbps.m4a file, right clicked and chose to open with Quicktime.

I noticed that the H264 file originally seems to come with PCM sound – perhaps there is a way to remove the PCM sound as it might be conflicting with the AAC sound?

Just noticed in H264 for audio there is enabled, disabled and passthrough – will tinker with disabled and passthrough. Am I on the right track?

Happy days – a speed improvement thanks to all your kind suggestions.

When I moved the Raid card from slot 3 into slot 4, I noticed for the first time that the word ‘Raid’ was printed only next to slot 4 – I don’t know how I didn’t spot that the first time. My eyes were probably watery with nerves as I tried to install the PCI card – might account for it!

Thanks Jeremy and David

Aha! Solved it – had to erase the volume as per Sonnet instructions and then the single Raid Drive auto-configured and appeared on my desktop.

Pretty scary that you have to ‘erase’ it for it to appear properly!

Thanks as always!

I’ve now got a Raid 5 (128k interleave, prefetch 5) which uses all 8 drives. Will setup my Atto alerts now, and use FCP remover to prepare for a fresh install of FCP. Before installing though, I’ll update my OSX and repair all permissions. Backup drive already cloned. I’m learning fast on these forums thanks to you guys, I can tell ya!

I am on the verge of partitioning my Raid 5 as one drive in Apple Disk Utility.

I don’t plan to use my Raid 5 as a boot drive.

There is an option to ‘Install Mac OS 9 Disk Drivers’ – do I need to tick ‘yes’ for this?

Hi Jeremy

Ah yes, totally – makes sense. Thanks!

128k interleave and prefetch set to 5 it is then.

Thanks Jeremy

I’ve posted an email I received from Sonnet just after you mentioned to stick with Raid 5 – what do you think? I’m a bit confused about which of the read/write options I should choose in order to get maximum performance for FCP6.
