G5 Power PC Mac not keeping up with HD video

[Michael Gissing]

Are you sure it is the computer and not the drives? Are your drives close to full?

I have run HD for three years on my G5 dual 2.5gig without problems from uncompressed 10 bit, HDV, DVCProHD and ProRes.

Hi David,
What kind of HD?
I’ve been working with EX-1 footage in a G5 similar than your’s without problem.
Working with a G5 you should read this thread:

Thank you.

You know, I think it might be the drives. My video is on external USB 2.0 drives and they are pretty full.

For a test tonight I copied some of the files to an internal SATA drive with plenty of room and the files played back just fine.

Thanks, people, I might have found my answer.

By the way – for arguments sake – would a new 24″ intel iMac be satisfactory for commercial HD production? My thoughts were that these new models would blow my G5 away and would be worth every cent to upgrade, but would this indeed be the case?

Cheers!

USB is not recommended for video.

[David Rodney]

Yeah, I see why. Although no probs with USB until I started with HD.

USB drives have never been recommend for video period.

Anything that is beyond 75% full will start to slow down, sometimes dramatically.

yeah never use usb, even if it works it may not
when you need it.

better to just do an internal drive at the very least.

Hi

The 24″imac would work if it can get the data off the drives in time. The key is sorting out your video storage. FW800 would be good enough for external video drives when working with compressed HD like DVCPro HD or Prores HD.
