AVC-Intra efficiency - new system?

[ROne]

Edius based dual core systems - happily edited my DVC-Pro HD 720/1080p programmes for a while. Keen to have a play with AVC-intra over the weekend (and despite not owning an AVC-I camera) - downloaded some P2 based clips.

I was a little underwhelmed with my systems performance with it. The CPU was overloaded and it wouldn't play 1 stream in real-time. Now I know this stuff is scalable but I can get 2-3 streams of 1080p DVC-Pro Hd. And more in 720p.

Am I missing something, as I was of the undestanding that Intra would put only a reasonable demand on the hardware/software during editing? It appears to be a sizeable leap up from DVC-Pro HD in terms of hunger.

What sort of a system have we to jump to get good real-time results, because as it stands I'm sticking with the codec that works for me, and that dictates my cameras.

This was the same with AVCHD - it's great having these new super-efficient codecs - and I know things will catch up; but there is very little to tempt me away from DVC-Pro HD at the moment.

It is a sizeable leap up in hardware demands. I can get 5 streams of DVCPRO-HD in realtime on my laptop, but only one of AVC-Intra. Even so, one is enough for almost anything.

But yes, AVC is more hardware power-hungry than the older codecs. AVCHD even moreso; EDIUS can only deliver about 12fps in realtime on my system.

However, a lot of this is somehow fixable because I have the Nero software, and Nero Showtime can show a full-screen 1080p AVCHD file in realtime, so it's obviously possible. Perhaps Nero is tying in to the graphics card for acceleration, and EDIUS doesn't?

In any case, expect that you will have less responsive performance with AVC-Intra as vs. DVCPRO-HD.
