Preview rate

margaret-taylor wrote on 6/10/2013, 8:50 AM

I have just changed to Windows 8, installed Vegas Pro 12 and copied my projects from my previous computer running Windows 7. I can't figure out why but the preview is slow and lagging and it's difficult to edit. Can anyone help me figure it out please?

The first time you open a project from an old version, it needs to rebuild its peaks, previews, and proxies. Sometimes this takes a long time. After it's done with that, timeline performance should be better the next time you open it.

If you still have problems, there are some tricks for better preview performance:

-- Match Media Settings (search it, don't guess at it)
-- Scale to Fit Preview = Off.
-- Simulate Device Aspect = Off
-- Change Source Media = Off
-- Try changing GPU settings

THANKYOU! It works. Even with new clips, there had been staggered play but your "tricks" have sorted things. I really appreciate you posting on here. Thank you again

Sorry to come back again on this, but on reopening Vegas Pro later in the day, the video has gone back to staggering on preview. I have checked that what you suggested is still the same. Can't figure it out ... Any help again would be really appreciated

@Caraelius
a) what is your full system spec including driver for your card?
b) why did you change to Win 8?

Hi OldSmoke

I have Windows 8-64bit
Intel i7 CPU @ 2.10 GHz, 8gb memory,
Nvdia GeForce GT640M

Old computer went to my husband and I bought new one which came with Windows 8 but I'm beginning to hate it!

Hope you can help

From what I gather you not only changed to Win 8 but actually changed the complete hardware? I believe that is a laptop since the GT640M is a mobile card? Which driver are you using with it and have you tried switching off GPU acceleration? The GT640M I believe is based on Keppler architecture although there are some unique ones that are rebranded GF108 chips. Something like GPU-Z could shade some light on it.

Yes I bought a new desktop with Windows 8 already installed on it. I'll try switching off GPU acceleration and see what that does. Thanks

Thank you for this link wwjd. It's really helpful

Thanks OldSmoke. Switching off the GPU acceleration has worked and the video plays smoothly.
Thanks again to all for their help (again)
