I have been using Vegas Pro since version 7. My video editing over the past 5 or so years has been pretty sporadic so I stayed with version 12. I recently upgraded from 12 to 18 and I'm impressed with the many additions to the product. But one thing really puzzles me... as far as I can remember Dynamic Ram Preview has been a frequent topic of discussion throughout the past 14 or so years. I bring this up because I am editing a complex animation that uses track motion on 45 tracks. I first created this in Vegas 12 on an old Dell i7 processor. I'm now Vegas 18 with a much faster processor and gpu, yet when I attempted to render this 14 second clip it would never complete... until I changed Dynamic Ram Preview from the default 200 MB to 0. I recall people having to do that many years ago, perhaps all the way back to version 7. My questions are:
1. Why is Vegas so sensitive to this setting?
2. If, as it seems, the advice is frequently to set it to 0, why isn't that the default setting?
While I'm at it, I believe there used to be a setting to tell Vegas to release files when Vegas loses focus, making it possible to use Vegas and Photoshop side by side for update (PS) and preview (VP). I can't seem to find that setting anywhere - is it still around?
Thanks for your insights!
