I’m only now switching to HD and not sure what format to give the final product to my clients. Is it possible on most new(ish) laptops to play a HD quicktime file properly without jerkinesh or pauses straight from the dvd drive or memstick(flash drive)?
1280 x 720 should be fine on most things - the data rate per second should be quite low with hd codecs like wmv or h264 - a lot of screens won’t take full hd at 1920 x 1080 so you’re right to supply two versions.
