As has been discussed, if you hold down the Shift key while selecting Preferences from the Menu, you will get an additional tab labeled Internal. This tab allows you to change a wide variety of hidden Vegas settings, in addition to the recently discussed default Maximum Preview Ram setting of 1024 MB. Here are a few other settings that I've noticed and/or tinkered with so far:
1) There is a setting to change the minimum preview frame usage. It defaults to 5 frames. If you set it to 1, it gives a smoother preview, in some circumstances, especially when using Preview settings like Best/All. The results are not profound nor are they consistent. This needs more investigation.
2) There are two settings related to Inverse Telecine. One enables it. The other uses it. Enable defaults to FALSE. Use defaults to TRUE. Has anybody played with these settings and in what context? I assume that they allow conversion of 29.97 FPS to 24 FPS, but why are there two settings?
3) There is a setting for the maximum amount of RAM that Vegas will use (not including the Preview RAM). The default is 384 MB (which offhand seems low for a program like Vegas). When you look at RAM usage by program, using a utility such as Process Explorer (which is just a glorified version of the Windows Task Manager), you see that Vegas tends to use right up to this maximum value, but also has additional memory swapped out to the Windows Page File. By raising this value to 512 MB, more RAM was used and the Vegas Page File usage dropped by the same amount. This may or may not influence real world performance, because it is possible that only transiently used DLLs (Vegas libraries) are swapped out to the Page File. Again more testing is needed.
Has anyone else played with these or other settings?
