15 frames per second is definately going to be somewhat jerky compared

to the normal 24-30 used in film and TV. But you can create Flash

animations at 30fps (they need to be converted to drop fram 29.97 fps

for true NTSC) but you normally need a very fast computer to display a

Flash movie at that rate.

Film ,a standard in animation, is only 24 fps and looks pretty good on

TV. The European frame rate is 25 fps.


For high quality and stability you would not output directly from Flash

to video. You would likely output Flash to an avi or quicktime movie at

the exact dimension that your NTSC (or PAL) video card supports and then

transfer to video (or film) from there. During the transfer you need a

fast computer with big hard drives. But during authoring you can use any

computer for animation but need a fast computer to see full speed

animation if you are doing 24-30 frames per second.

There have been quite a few commercials created in Flash.


There are a lot of a considerations in creating animations for TV and

film that are different from regular computer presentations; colors,

pedestal, gamma, contrast range and safe area are just a few.
