CyberLink Uses ATI Card To Transcode Four 1080p Video Files Simultaneously
Posted by Jason Chen at 8:00 AM on June 27, 2008
The fashionable thing these days is to take the tremendous processing power of graphics cards and put them to use when you're not utilising them to render games. CyberLink, for one, has come up with a pretty ingenous method to take an ATI or NVIDIA card (in their case, the demo was on an ATI Radeon 4850 512MB card) and convert four 1080p MPEG-2 movies into MPEG-4. Simultaneously. As long as you've got a pretty fast video card, all you need is a copy of CyberLink PowerDirector 7 and you can be doing this too. We hope this is the kind of thing Apple's going to be putting into Snow Leopard. [TG Daily]

Very nice.
Hopefully More converters come out that can do this.
It would be cool to be able to convert videos with your graphics card and still do everything else at the same speed as normal (minus of course playing games or other graphic heavy apps haha)

Can't the ps3's cell do that?

@jitty9:
i doubt it. the cell's claim to fame was decoding 48 MPEG-2 SD video streams at once, or 6 HD screens.
encoding takes much, much more processing power than decoding. anyone who's encoded an MP3 can tell you how much CPU power it takes up, while playing it back takes practically 0%.
what the card is doing right now is simultaneously decoding 4 1080p MPEG-2 streams AND encoding 4 MPEG-4 (also note, much more demanding than MPEG-2) at the same time. it is leaps and bounds ahead of the cell.

@willyolio: errr 0 percent , what computer are you using , just idling a computer takes 5 - 15 percent processor power, let alone running a mp3 application.

@ichi1:
first, i said PRACTICALLY zero.
second, your computer must be ridiculously bogged down with spyware. i suggest you run a cleaner app like ad-aware. in any case, i was talking about MP3 playback, not all the unrelated programs in the background of your computer.
third, my computer is fairly old. I run an athlon64 3000+. playing back MP3's on winamp, it never jumps over 2%, and it regularly spends its time at 0%. on a more modern processor, it should definitely be sitting at 0-1%. miscellaneous windows processes easily take up more CPU time than playing back MP3s.

@ichi1
you must have spyware/adware on your machine. An idling computer without any software intentionally running in the background should be 0% as shown by task manager, although that 0% is really a rounded off number.
