630m when is overclocked is just monste
This is pretty crazy. Thankfully I don't use many layers right now, superimposed titles at most. I'll have to check if I start doing more complex work. Thanks for sharing.
Arm appears at 1:04
I will have to delete this video soon, but it was the draft version in which the background has substantial variations in shading. You should be able to see dark patches, distinct lines where the different layers vary in shading and even an arm that appears behind the presenter from the lower layer. When I edited this on my GT 630 the background was pure white and none of these issues were visible. I use high quality calibrated monitors. Even altering the lightness/contrast/gamma could not make these issues visible. http://youtu.be/mT8vD_mJZYs
It's fast but it's just not optimal image quality. Absolutely no good for video editing where you need to ensure consistency of color or shade.I would never have picked it up except that I have two computers and luckily I viewed the video on the other computer after the client complained. Basically the problem is totally invisible on your screen (using the GT630). In one instance there was a hand showing through from another layer which was invisible when viewed with the GT630 but visible on other computers. I may try and get some screen shots.
Crap, I should have read this 4 months ago when I decided to buy a GT 630 because that's the only GPU series that Sony Vegas supports. What sort of issues do you have? I want to check if I'm having the same problem.
I just did some video editing on my i7 laptop with a GeForce GT630M graphics card. I uploaded the resulting video to YouTube and then watched it on my old desktop with a Geforce GTS 450. To my horror, I could see all the variations in shading which were totally invisible on the 630M. So I went back and re-calibrated all the monitors. Again the shading variations were still totally invisible on the 630M but obvious on the GTS 450. Even my client could see the visual problems on his cheap computer. Correcting the issues was a nightmare. No matter how much I adjusted the screen of the 630M (making it super dark or adjusting the gamma or contrast)it made no difference, the background looked completely white and some objects were totally invisible. In the end I had to virtually fix the problem working blind. I had to kept adjusting the levels and applying masks, render out the footage and transfer it to the other computer to be able to see if it worked. It took days. I now know that my 630M is completely useless for video editing. The degree of shading is extremely poor. I have high quality monitors but it makes no difference and all my screens are callibrated.
I love My GeForce GTS 450
