My school just bought me a new computer for my desk. As you know, schools don't always by the latest and fastest stuff to go on a teacher's desk. I just fired up Vegas to see what it would do with the new machine and I hit the floor. I don't like to edit AVCHD. I prefer to encode it to XDCAM or something else for edit but I thought I would watch the machine choke on some AVCHD. Holy cow!
With two layers of AVCHD set to partial transparency, preview set to Best, Full and the whole thing being displayed on a secondary monitor .... 29.97 solid.
When I added multiple crossfades or 3d transitions it did choke, but setting it to preview, full brought it right back to more than 24fps.
This is reading from the system drive as well.
For the folks who ask about what computer, here is what they bought me:
HP Compaq dc7900 Small Form (full tower) with an Intel Core 2 Duo E8400 @3.00GHz and 4 Gig of ram. Two 160 Gb drives and two 24" HP monitors that have sRGB display. Windows XP sp3.
No complaints here.
