The Latest CUDA App: MotionDSP’s vReveal
NVIDIA had more slides in its GTX 275 presentation about non-gaming applications than it did about how the 275 performed in games. One such application is MotionDSP’s vReveal - a CUDA enabled video post processing application than can clean up poorly recorded video.
The application’s interface is simple:
Import your videos (anything with a supported codec on your system pretty much) and then select enhance.
You can auto-enhance with a single click (super useful) or even go in and tweak individual sliders and settings on your own in the advanced mode.
The changes you make to the video are visible on the fly, but the real time preview is faster on a NVIDIA GPU than if you rely on the CPU alone.
When you’re all done, simply hit save to disk and the video will be re-encoded with the proper changes. The encoding process takes place entirely on the GPU but it can also work on a CPU.
First let’s look at the end results. We took three videos, one recorded using Derek’s wife’s Blackberry and two from me on a Canon HD cam (but at low res) in my office.
I relied on vReveal’s auto tune to fix the videos and I’ve posted the originals and vReveal versions on YouTube. The videos are below:
In every single instance, the resulting video looks better. While it’s not quite the technology you see in shows like 24, it does make your videos look better and it does do it pretty quickly. There’s no real support for video editing here and I’m not familiar enough with the post processing software market to say whether or not there are better alternatives, but vReveal does do what it says it does. And it uses the GPU.
Performance is also very good on even a reasonably priced GPU. It took 51 seconds for the GeForce GTX 260 to save the first test video, it took my Dell Studio XPS 435’s Core i7 920 just over 3 minutes to do the same task.
It’s a neat application. It works as advertised, but it only works on NVIDIA hardware. Will it make me want to buy a NVIDIA GPU over an ATI one? Nope. If all things are equal (price, power and gaming performance) then perhaps. But if ATI provides a better gaming experience, I don’t believe it’s compelling enough.
First, the software isn’t free - it’s an added expense. Badaboom costs $30, vReveal costs $50. It’s not the most expensive software in the world, but it’s not free.
And secondly, what happens if your next GPU isn’t from NVIDIA? While vReveal will continue to work, you no longer get GPU acceleration. A vReveal-like app written in OpenCL will work on all three vendors’ hardware, as long as they support OpenCL.
If NVIDIA really wants to take care of its customers, it can start by giving away vReveal (and Badaboom) to people who purchase these high end graphics cards. If you want to add value, don’t tell users that they should want these things, give it to them. The burden of proof is on NVIDIA to show that these CUDA enabled applications are worth supporting rather than waiting for cross-vendor OpenCL versions.
Do you feel any differently?

Can anyone tell me about the testing metod average or maximum fps? thanks.Jamahl - Thursday, April 2, 2009 - link
some sites have the gtx275 clearly winning at all games, all resolutions.helldrell666 - Thursday, April 2, 2009 - link
You can't trust every site you check.especially since most of those sites don't post their funders names on their main page.You must've heard of Hardocp's Kyle who was fired by nvidia because he mentioned that the gtx250 is a renamed 9800gtx.7Enigma - Thursday, April 2, 2009 - link
I think this is due to Nvidia shooting themselves in the leg with the 185 drivers. With the performance penalty at the normal resolutions, anyone testing with the 185's is going to get lower results than someone testing with the previous drivers. And I'm sure you could find 10 games that all perform better on ATI/NVIDIA. That's the problem with game selection and the only real answer is what types of games you play and what engines you think will be used heavily for the next 2 years.SiliconDoc - Monday, April 6, 2009 - link
Well the REAL ANSWER is - if you play at 2650, or even if you don't, and have been a red raging babbling lying idiot red rooster for 6 months plus pretending along with Derek that 2650x is the only thing that matters, now you have a driver for NVidia that whips the ati top dog core...If you're ready to reverse 6 months of red ranting and raving for 2560X ati wins it all, just keep the prior NV driver, so the red roosters screaming they now win because they suddenly are stuck at the LOWER REZ tier to claim a win, can be blasted to pieces anyway- at that resolution.
So - NVidia now has a driver choice - the new for the high rez crown they took from the red fanboy ragers, and the prior driver which SPANKS THE RED CARD AGAIN at the lower rez.
Make sure to collude with all the raging red roosters to keep that as hush hush as possible.
1. spank the 790 at lower rezz with the older Nvidia driver
2. spank the 790 at the highest rez with the new driver

Can someone ban this freaking idiot. The last few posts of his have been nothing but moronic, senseless rants. Jesus Christ, buy a gun and shoot yourself already.SiliconDoc - Tuesday, April 7, 2009 - link
Ahh, you don't like the points, so now you want death. Perhaps you should be banned, mr death wisher.If you don't like the DOZENS of valid points I made, TOO BAD - because you have no response - now you sound like krz1000 and his endless list of names, the looney red rooster that screeches the same thing you just did, then posts a link to youtube with a freaky slaughter video.
If I wasn't here, the endless LIES would go unopposed, now GO BACK and respond to my points LIKE MAN, if you have anything, which no doubt, you do not.

According to xbitlabs, the 4890 beats the gtx285 at 1920x1200 resolution with 4x aa in Cod5, Crysis Warhead, Stalker CS, Fallout 3 and loses in Far Cry2.Here, the 4890 matches in Far Cry 2 and cod5 with some slightly lower fps than the gtx285 in Crysis warhead.Strange....

That is crazy. There is no way variations should be that huge between the 2 tests, regardless of the area they chose to test in the game. Anandtech has it as essentially a wash, while Xbit has the 4890 20% faster!?! (COD:WaW)7Enigma - Thursday, April 2, 2009 - link
Just looked closer at the Xbitlabs review. The card they used was an OC variant that had 900MHz core instead of the stock 850MHz. In certain games that are not super graphically intensive I'm willing to bet at 1920X1200 they may still be core starved and not memory starved so a 50MHz increase may explain the discrepancy.I've got to admit you need to take the Xbitlabs article with a grain of salt if they are using the OC variant as the base 4890 in all of their charts....that's pretty shady...
