Sony Vegas Pro Forum.

You should do your own search, but here are a few threads that may help:

Quicktime version?

VP13 freezing when editing Quicktime(Prores422)?

Recommended Quicktime version for Vegas 12?

Quicktime version

There are GPU options for rendering in some (but not all) of the Render As template settings. However, the GPU settings for timeline playback are in the Options --> Preferences --> Video dialog. The Vegas Help system will also take you there. Any reason you didn't try using the help system before asking? All you have to do is type "GPU" in the help search and it gives you exactly the same answer I just gave.
I have tried all those advices and I have tried different quicktime versions and nothign changes. Im losing hope and I might end up rendering the mp4 with vegas to convert it to AVC format then start editing... I dont see any other solutions.

I still didnt try quicktime alternative but you said its sketchy so im not sure. U mean it can contain virus?
