I’m on an i7-940 with 12 gig ram (custom made),Vista 64 and Production Premium CS4 works like a charm.
Edits HDV like butter. Tried some avchd: very smooth. So do my Cineform avi’s.
If you extend the project window you will see all kinds of metadata displayed.
You can choose any of these columns (click on the name) to get you clips in the correct order you like them to be.
In CS4 make a new sequence, copy from old sequence and drop it into the new.
Other versions you will have to make a new project with the settings set in the editing mode/desktop. Import older project into new one.
