Current Graphic Cards - Can they do 3D PiP in realtime ?

[dada]

Hi,
I'm thinking about upgrading my GraCa.
As the 3D PiP is rendered on the GPU, I hope there's a chance for realtime playback.
Anyone here using a ATI 4890 or 5870 with 1gb DDR5 ( or similar NVIDIA ) ?
Does the improved memory bandwidth help, or is the bottleneck somewhere else ??
Is realtime 3D PiP possible at all ?


Thanks, Jan

3D PinP does not use the GPU at all. It uses the CPU.

Only GPUFX (Transitions only) use the graphics card in EDIUS 5

Thanks, Dave.
Looks like I misinterpreted something I read, here ...

OK ... did some more investigating ...
The 3D PiP realtime performance is somewhat 'broken' in V 5.x.

I started with Edius V.5
Is there a way, to get the complete V.4 installer ?
And even more important :
Can V.4 3D PiP do 'rotate' ??

When you say 'its broken' what exactly are you seeing?

I am using 5.12 and although it does work slightly differently to the one in Ver5, it does not seem to be 'broken'.
I use it nearly everyday moving graphics and titles around the screen, keyframing their position etc.. and all in realtime.

Jan, with my new i7 system RT is back on 3D PIP/EDIUS 5.12

I am realtime with 3DPIP. "Broken" just means that in this version it makes a much bigger hit on the CPU than past versions did.

Yep, that's what I meant.
And that bigger hit seems to be even bigger than grass valley expected ( according to a forum mod ).
But obviously it couldn't be improved, in 5.1.x.

Does anyone know, if 'rotate' was already in V.4.6 ??
If yes, I'll try to get a V.4 disk or download.
I do have V.4 registered in my account, so it should be possible ...
Next bigger system upgrade is a bit ahead.
( my main business is audio and my current system is rock solid and has more than enough power, for audio tasks )

IIRC it did have rotate

Thanks, David & Eric.
Can You do multiple layers of 3D PiP in RT ?
I read that in V.4, it was possible to have 3 layers of 3D PiP,
even on those older systems.

Actually I won't need more than 1 3D PiP FX, but sometimes 2 or 3 region FX in addition to the PiP.
AFAIK, 'region' is another FX needing much more resources in V.5 ...

Thanks PS.
Will try to contact the german distributor.
