What frame rate should you build your Flash file at?

Question

Every second of video has 30 frames. But Flash animations can
be done at any frame rate, which raises a couple of important
questions:what frame rate should you work at, and second, if you
choose to work at a rate other than 30 frames per second (fps), how
do you convert to 30 fps? I deal with the question of frame rate
conversion below.
You can create a Flash movie at 30 fps. But if is going to be
played back on a computer, a 30 fps .swf file will generally
produce unacceptably high data rates, unless the image is very
small and simple, or the computer it is playing on is very fast. It
can also create a lot of extra animation work if you want to draw
in-betweens for all 30 frames. Fortunately, there is no need to
build your Flash movie at 30 fps, even if you are planning to
transfer it to video.
I usually build animation that needs to work on the web or
video at 12 fps. This gives us a good balance of lower data rates
and smoother animation. When creating cartoon style animation, it
also keeps our work consistent with the majority of broadcast
animation. While some high end cel animation is done at 24 frames
per second (the rate that film is projected at), much broadcast
animation is created at 12 fps. This is because it is drawn on
"2's." In other words, each image holds for 2 frames. Do the math
and it becomes clear why--half the amount of frames to draw each
second. While Disney and Dreamworks may have virtually unlimited
budgets to create their epic animations, most broadcast (and even
more so, Internet) productions are on very tight budgets. But even
the big studios do a lot of character animation on 2's. It looks
good that way, so why create twice the work?
If we are using flash to build a cartoon solely aimed at
broadcast or film, however, we build it at 24 fps. That way we can
animate on 2's for most of the character animation, but do animate
on 1's for segments or particular motions that require smoother
animation.
If we are using Flash to build graphics for broadcast use
only, and so won't be hand drawing in betweens, we usually build
the file at 30 fps. This will give us the smoothest motion, and
data rate won't be an issue for you. It is also possible to even
build it at 60 fps, and convert this to a 30 fps video with fields
In the end, you can decide to build it at any rate you want.
The lower the rate, the smaller the file size, data rate and number
of frames to animate, but the less smooth the animation.
Conversely, the higher the frame rate, the higher the file size,
data rate and number of frames to animate, but with smoother
animation.
now I use
FLASH VIDEO MX PRO
to covnert Video in multiple formats to FLV or SWF, I set the frame
size just as above, I always get soomth Flash
at the meantime, I have to set video rate when I use
FLV To Video Convert
Pro to play the video in my iPod, if you set the wrong frame
rate, your iPod and other devices may not support the frame rate

Answer 1

Usually video quality has nothing with frame rate, but when
you convert flash to iPhone or other devices, you should think of
which frame rate video can your device play. when I convert .swf to
iPhone with
SWF to Video
Converter, as you know, iPhone can only support frame rate from
2 to 15 or a little more, I always choose 15. In this scare, frame
rate is higher, the quality is better.
