Capture oversaturation issue solved...whoops, not solved
A couple of months ago, leaky capacitors caused me to ditch my epox 8k7a
motherboard and replace it with an ecs n2u400-a. Before the switch, I was using a couple of utilities to control the input from the Philips saa7108e chip on my gainward geforce3 videocard (the gain settings are far too high, especially on the s-video input, causing some really nasty image oversaturation). One of the utilities, called video live wdm (vlio.sys + registry entries and a batch file for installation), is a driver that allows access to the settings on the 7108 through another utility, called "evip manager". Brightness, contrast, anti-aliasing and comb filters, manual gain/agc, ntsc (-m and -j), pal, and many other usually inaccessible chip features can be adjusted or set; after the motherboard switch, though, I have been trying fruitlessly to get the setup to work again. After experimenting with seemingly endless versions of nvidia/gainward display and vivo drivers, checking motherboard settings, and changing the installation and reboot sequence, I had no luck gaining access to the chip registers - the evip manager comes up, but the sliders are all at zero and the radio buttons are set to the first choices, and trying to move the sliders or click the radio buttons is a waste of effort. I have even tried contacting the author of the software, Igor Lookin, but as yet (over two months) I have not received a response. I am really desperate to get my setup back in order, so I was hoping one of you may be able to help me out: I will take any and all advice that has a chance of resolving this. Has anyone with a similar rig to mine been able to run the video live i/o + evip manager successfully? How did you do it? What version of the display/wdm/motherboard drivers are you using? At one point, I decided enough was enough and ordered a Canopus ADVC-110, but was unimpressed. Aside from an exaggeration of the reds (and a slight push of greens), the device squishes the high end of the luminance range somewhat, not like my other card, but it is still noticeable on some captures containing nuanced whites. In addition, the Canopus DV codec leaves behind artifacts that would not be present if I were able to capture in Huffyuv with my analog board; so now I'm back to square one. Steen4 |
