Looking to upgrade our main multimedia production machine from CS3 to CS4, but we probably won't upgrade all the other machines just yet.
Main question: If you work on a Flash file in CS4, can you work on it in CS3 and save it, or will some of the functionality be lost in doing so? Or is a matter of just having to save it in a certain way to make sure it works?
Also, is there any issue with importing CS3 Illustrator, Flash or any other kind of files into After Effects CS4?
cs4 can save files for cs3 so, it "..is a matter of just having to save it in a certain way..".
you could lose some functionality if you used any flash player 10 capabilites that aren't in fp 9. to prevent that you would always publish for fp 9 in your cs4 file to ensure you could use the file in cs3.
i can't see any problems with importing non-flash cs4 files into flash cs3.
