I just dowloaded it and ran it on one of my PC's. Here is the link to a bootable image to burn:

I was recommended to let it run for two full passes to be sure. My PC had faulty RAM and it showed up very fast and I got a few new sticks.

weird... i had red screen's when trying out Craig Longman's 64-bit version of the Smart Deinterlace filter on some HD footage.

the Smart Deinterlacer would work, then when i skipped ahead or back, the Preview Window would go red... if i turned the filter off, it'd return to normal... if i changed the Preview quality it'd return to normal... resizing the Preview window didn't tho... and after a few more skips on the timeline the Window would go red again.

i'd assumed (and still do i guess) my computer simply didn't like Craig's recompile... i've not seen a red screen on my computer using any version of Vegas til now and hadn't used the plugin before... i did used to get black frames when working with PNG / TGA sequences but that stopped a while ago.

i may check RAM anyway... i do get system freezes every once-in-a-while running Vegas (usually a bunch in a day then it goes away for a week or two)... thx for posting the link Ulf!

...anyway, my experience probably isn't related to the OP but thought i should mention it just in case.

Ran the mem test a few passes. No errors found. I wish there were, then I would feel like it's an easy fix. Will run it overnight later.

Ok, it doesnt seem to happen in 64bit edition in 8 or 32 bit color but it repeatedly does occur when I change from 8 bit to32 color then set preview to best/full.

Is there any reason why you're using 32bit float?

Was doing a glow effect on text and when there is a lot of glow on you can see the raterization lines in the 8 bit. It's only for stuff like that so I can of course just render that in 64 bit or whatever.

When I ran the mem test all night it came up with 2 errors on pass # 5. However I note that my DDR memory is 9-9-9-20 and my motherboard auto detected 8-8-8-20 so then I tried manually setting RAM latency to 9-9-9 and the Red screen issue still occurred. But now I am not sure if the mem errors detected by memtest was dues to incorrect auto detected latency settings or not. Will have to run the memtest again. I still have time to exchange my RAM if that is my issue, less that 2 weeks old.

Ok so I ran vegas in windows safe mode and find that the red screen doesnt happen at all. This may point to my video card being the issue since the video drivers were not loaded in safe mode. That could very well be since I have a new video card.

That woudl be unfortuate as I wanted a silent video card with no fan and I have gone through som of the limited choices in those cards already to find the one I liked. I have the latest drivers.

Just updating the post as I diagnose this for others who might read it.

"Was doing a glow effect on text and when there is a lot of glow on you can see the raterization lines in the 8 bit"

Strange, they shouldn't be there is 8 bit and 32bit float should not change that. I suspect something else is tripping you up. Working at higher spatial resolution rather than higher bit depth would be my first way of fixing the problem.

I don't know if this is related to the OP's post or not, but I get a red screen crash, which is repeatable, every time I drag and drop around 40 1920 x 1080 25p clips to the timeline. Total size is around 4 GB. I get a Vegas not responding error.

I figured that this may be due to a lot of paging going on, but subsequent checks show that this is not so. I even waited overnight to see if Vegas (10a) would respond again. It didn't. I got around the issue by dragging and dropping about one third of the clips each time and it worked fine, so it's not a show stopper problem. Just puzzling is all.

It is probably something to do with the PC I'm using - laptop with only 3 GB mem available to Vista 32 bit OS. Even though I usually live in a caravan and am stuck for room, I can see a proper full-blown editing PC happening soon.

Ok I exchanged my RAM for a different brand and doubled it. Now I have 12GB of RAM and still get red screen when I switch to best quality preview level in 32 bit Vegas when using 32bit floating point. Brand new Asus P6T Mobo and i7950 windows 7 64 bit installation. Also the 10c update didnt help either. It cant be the CPU and i tried 2 different video cards getting the same result so the only thing left is the new mobo.

Any bright ideas???

I guess I should have poled the forum to find folks with absolutely no issues and purchased their exact hardware.

I can get around the 32bit float issue by using 8 bit or veg64 but I dont like having to go back and fourth to 32 to get my noise reduction and magic bullet effects to work and I shouldnt have to work around. No one else seems to be having this problem. Aaaarrrrrrrgggg.

I did the >2gb CFF Explorer tweak on the vegas.exe and FileIO Surrogate.exe files and my red screen problem in 32bit vegas with 32 bit floating point is gone!!! Yeah for me!!!

Thanks Rob.

I tried the same thing and it fixed my problem as well. Just dropped 112 HD files to the timeline and it did it in seconds, without red screen crash. (See post a couple above yours.)
