Hi guys,
Just read through this article I also checked out this site originally, but their gpu recommendations are a bit vague =/ Looks like the gtx 260+ rips through 1080p transcoding on CUDA supporting video editing software. With my logic, the gtx285 should be faster still, right? And, considering its the fastest single GPU nvidia card, i'm thinking it's the best for the job. What i'm not sure about is dual GPU though, do any programs support sli for CUDA video editing? Secondly, what advantage is there in getting a quadro, if any, for this purpose? (forget gaming, we're talking pure video editing here). I basically want the fastest video editing rig for under 5k. Core i7 975, 128GB SSD and 12GB ram already chosen, leaving about $650 for graphics. And finally, is the 5870 any good for video editing? I.e. Does any editing software actually support ati steam? Any info would be much appreciated, thx guys! |

Video editing software such as Adobe AfterEffects CS4 and Premier CS4 support OpenGL Acceleration. Thats about it for video editing.
Others such as Badaboom, support Cuda to convert videos with GPU Acceleration. I really dont think SLI is supported for most Cuda video codecs. If your just doing video editing, Quadro isnt really needed, a Ge Force card should be fine. If your doing CAD / 3D graphics, Quadro is a huge increase in performance, For example, My Quadro FX580 (Entry Level Card) has a huge increase in fps, quality and quantity on screen then my GTX285. But when it comes to video editing, there isnt much of a difference. You rather increases the ram amount and cpu as you will use those more then the graphics card for video editing. Adobe AfterEffects and Premier supports both Nvidia Cuda and ATi Stream, but some say that its better on Nvidia, but i guess because Nvidia has had cuda for a while. Like i said before, Adobe AfterEffects CS4 and Premier CS4 are possibly the one of the few video editing programs which use the graphics card, but they only use the OpenGL side. |

CPU, Ram and HDD are still the main factors!
And you have covered all these areas nicely... I believe the video cards "only" help you at the final stage. But when you cut and paste, add soundtracks, add effects it is mostly the CPU, Ram and HDD... |

Have Cuda apps matured? Last i heard, the transcoding products using Cuda were only a little faster than non-gpu software and produced mediocre quality.

Badaboom is probably the only fastest transcoding product using cuda, although it has limited formats it can take. Its faster then non-gpu software by alot in my opinion, but its only limited by its formats it accepts.

Wow, perfect reply, thanks alot mate! So if i understand you correctly you're saying that only adobe cs4 supports the gpu for actual effects etc whereas the others support it just for transcoding?
Thx very much for the quadro info, i suspected as much myself but wanted to be one hundred percent sure. I think i'll stick with the gtx285 for now as CUDA is more mature, and if ever need be can always swap in a 5870 later down the track. Thx all! Quote:

Glad I could help,
Yep, Adobe CS4 Suite is possibly the only Creative Suites that support GPU Acceleration in their programs. Some other programs might only just support plugins for codecs that work with GPU acceleration. |
