Hello Manraj Singh,
my first impressions of CS4 are very very good. After much grief with CS3, I was skeptical about CS4, and even toying with the ultimate switch to FinalCut.
But CS4 seems real sweet – albeit, these are just first impressions with just 2 short projects over the period of a week.
The most important changes to me are the new (well except old Premiere 5 used to have it) BATCH ENCODE… and finally getting your material to easily preview on the device of your choosing, i.e. an external monitor not hooked up to a DV-device. Just with a mouse click, like Final Cut.
I haven’t tested it yet, but like FCP you can now also mix formats on the same sequence.
In general, my system seems faster/more stable with CS4 than CS3… I have read somewhere that CS4 administers the memory more effectively. Anyway the entire week was free of any glitches!
good luck,
ninetto m.
