Sony Vegas – 64 bit / 32 bit performance
A few days ago I reinstalled Windows 7 using the 32 bit disc instead of the 64 bit, due to what I then thought was a driver issue with my Mobile Broadband.
I don’t know if I’m imagining it, or if different clips in use are giving an incomparable impression, but the preview window often seems more juddery than it was.
I did take some RAM out, but it’s still only using a third of the 2gb RAM anyway.
Is this what I can expect, does it make sense? If so it’s back to 64 bit for me – but I had thought that Vegas was a 32 bit program that was merely 64 bit-compatible.

Sorry, I should probably add that it’s Sony Vegas Platinum 9 I’m using, not Pro.

2GB of RAM is not a lot to be running Windows 7. I would put RAM back in if you have it. The 64-bit version of Windows 7 only starts to make sense if you have 4GB of RAM or more. If you have less than that, the 32-bit version is fine to use.

Put the RAM back in and re-test.

I am having a problem with my outboard JVC pro monitor and Vegas 9 set-up. I bought a Blackmagic Intensity card so that I could have two computer monitors for editing and an output for the JVC to see video. But the JVC picture quality is set by the Vegas preview window settings (full, half, good, best) and the picture is jittery, unlike any outboard monitor I have ever seen, including this system with Premiere. I cannot see an edit properly unless it is rendered which is completely unacceptable. I cannot believe that all Vegas users are putting up with this. I have Vegas 9e 64bit on an Intel 2QuadCPU Q6600 @ 2.4 GHz with 8 Gigs ram and ATI video card. If I must, I will give up my second computer screen. Thanks in advance for your advice.

Putting the RAM back didn’t change anything. I’ve gone back to 64 bit now. The smoothness of the preview screen varies. I know my Flip mp4 clips contribute to this because of their type of compression or whatever, but I notice that clips with more light in are the most juddery. A clip in a restaurant and another in an aquarium are smooth, but two made walking along a street in daytime and good sunlight aren’t. Overall Vegas is not running as smoothly as it had four Windows 7 installations ago. Should changing the RAM allocated to video have any effect on this? It starts at 128mb but I always change that to 256mb or 384mb.
My system, AMD 3 ghz dual core, 4gb RAM, Windows 7 64 bit. My PNY/nVidia graphics card was inexpensive but has 512mb of its own RAM after a month or so of using the onboard, and I see there are people with quad core systems that still haven’t got smooth previews. Looking at the Performance tab of Task Manager, the CPU goes between 25 % and 55 %, the RAM 1.1 gb or less. Nothing’s really taxed, so I dodn’t get it. I’d like to get it back to being as (admittedly inconsistently) smooth as it was, not perfect, I don’t expect miracles. Any factors I mightn’t have considered?
Simpler video editing programs run the Flip clips well, like Videopad, which can show two clips running smoothly simultaneously on my 1.6 ghz dual core laptop, and the promising but buggy Linux ‘PiTiVi’. If Vegas is not doing everything it can do at once, and many of these things I’d never use as they’re too flash, then it’s a shame it’s consistently chomping resources or otherwise struggling. I don’t leave my internet on or have other stuff running when using Vegas, although I found during a period without broadband that there was no change with my AV software removed.

Bob, would you please re-post this as a new thread? Lee has made another post, and I have a difficult time keeping things straight when there is more than one primary issue being discussed. Thanks for understanding.

Hi Lee.
I am not the expert, but I would boost the RAM preview to 384, just as a troubleshooting measure.
What is the bitrate on your Flip camera? And when you compare files of similar length, one of a brightly lit environment and one of a darker environment, are they about the same size (in MB/GB)? Or are they radically different?
>> Overall Vegas is not running as smoothly as it had four Windows 7 installations ago.
Also, why did you find it necessary to reinstall Windows four times?

The bit rate of the Flip camera seems to average out to about 9000kbps. It’s a 720p device.
The Windows 7 reinstallations were half for other reasons than Vegas problems, but there seemed no reason to stick with 32 bit. Hopefully I won’t be wiping anything till this computer’s dead now…
Yes, the clips with a lot of light in, in two cases are very short, ten seconds, and yet juddery compared to a minute long bit of aquarium footage in subdued light. The bit rate can vary between 8800kbps to 1024, looking at some clips’ properties now, but light doesn’t seem to correlate to this as I’d expected. Indoor artificial light – a rail station in London – footage in my home in late afternoon/evening or 11 a.m. in the street in summer can be the upper or lower end of the bit rate range. Kooky.
(Turning off Aero/ using Windows Classic doesn’t help at all either.)
It’s a great program, I’d just love to iron this out…
