Video Cards: Video editing

Hellooooo!
I know a lot of reviews compare video cards when it comes to games, but I was curious if either brand is significantly better at video playback/video editing or do both pretty much do a good job and matters more for video card memory?

I'm not talking about x800 or 6800 series either
Just in general. Like say a 5200 ver a 9200 or even GF2 and radeon 7000 *and so on*
 
Video playback, there might be slight differences, but video editing is all cpu and the software you use.

Maybe you mean encoding?

yeah! :)

Anything relating to when the video card comes into play that is actually independant of the cpu or helps the cpu.
 
I have heard very little about video playback performance differences and I am willing to bet you wouldn't be able to tell the difference on most. The only issue there is probably the quality of the RAMDAC's on the output signal (especially for DVI) which would determine general 2D quality.

As far as encoding, you would definitely want to get a hardware encoder to minimize load on the cpu, but encoders do not come on normal graphics cards. You would have to find something like an All-In-Wonder (which is usually crap and does not normally have a hardware encoder) or Nvidia's Personal Cinema (I have no experience with these), or there are very good PVR cards like the Hauppauge 250/350 which do TV tuning and video encoding.
 
Another vote for Hauppauge 250/350, i used a few in a PVR box, great card. It can capture and encode DVD compliant mpeg. So you can capture video at DVD quality without using much of your CPU cycles.

Both cards capture quality is just the same but the 350 has TV out with mpeg Decoding (IIRC)
 
ATI all-in-wonder cards (newer ones anyway) offload a bit to the gpu. My 9700 AIW was great, it did perform better on P4 platforms but i never had any trouble on several Athlon based systems.
 
the 6800 series implemented a hardware encoding chip onboard that is spossed to offload the load from teh CPU. it has not been turned on in drivers yet however

iirc, DVI-D takes the signal directly. only the VGA needs to the RAMDAC to convert the signal from a digital one to an analog one. the cards have dual RAMDACs for dual VGA setup
