FCP and Compressor
Just upgraded FCP to hardware below – and I’m experiencing some problems with Compressor. I have a single rendered one hour DVCPRO HD video file from FCP I want to make into a DVD, this rendered fine in Toast (although the field order was back to front) and took approx 2 hours. However using compressor the render crashed the computer in my first 2 attempts, this time so far so good – but 2 hours have elapsed and the render bar has barely reached 10%.
Are these known problems when rendering HD to SD DVD via Compressor?
Maybe I should convert the HD file to SD prior to Compressor?
Any thoughts most welcome,
Cheers,
Ken.

Hi Ken
Before I used to send to Compressor any movie to be downsized-deinterlazed-compressed etc.
Now I prefer to do almost whatever task in FC and give to Compressor the movie ready to be transcoded.
I made the downsizing in FC.
Drop your DVCProHD movie in a Proress or 10b Unc SD sequence. Set “Render all YUV material in High Precision” and Motion Render: Compressor will need only to transcode your movie to MPG2. The process will be much faster and the results, the same.

Fantastic, I’ll do that.
Thanks,

I’ve dropped the DVCPRO HD 1080i clip into a FCP uncompressed 10 bit anamorphic timeline. I got a green bar so hit render and initially got an render estimate for about 14 hours. Rebooted the computer and this has come down to 2 hours. I’m finding if I work with multiple codecs the computer quickly starts to get clogged up somehow and everything slows down – until I reboot. Is this normal when working with FCP and HD?
Cheers,
Ken.

Hi Ken,
The 90% of the problem that the people suffer when working with FC (or any other application) they come from a poorly maintained system. If you every two or three weeks spend half hour in cleaning the caches, repairing permissions and cleaning the HDs directories you will minimize every kind of slows, crashes, general errors etc. Everything will go more stable and fast.
When you re-boot, the system makes a certain optimization but not enough. You need to run some applications to get it right. Apple knows that, therefor they include TechTools in theyr Apple care kit.

The render time is creeping up again – 5 hours now – so I’ll take your advice prior to the next reboot and run tech tools. Shame I can’t play out of the Kona LHe straight back to the hard disc – much quicker! Maybe if I got another Kona card for my old G4 system I could do that – cheaper than a DigiBeta and then I have realtime SDI transcoding….
Thanks,
Ken.
