RE: FLASH: Frame Rates and Computer or connection speed?

[Brack, Jeremy]

Faster computers such as G3, P3 and P4 will be able to handle the 60FPS

better than slow computers.  The download time is irrelevant unless your

putting in a new bitmap image on every frame in your movie.  A faster FPS

wont add any to the download time because your not putting in any additional

content.


A slow computer will choke when the animation gets too intensive.. you will

see the animation slow down a lot and then speed up again.

If slow computers are your target audience, then you should create movies

around 12 to 15 FPS to minimize the slowdown.  24 FPS is a good medium speed

when your audience is a mix of fast and slow PCs.


If you want to make seperate versions for fast and slow PCS, you should look

for some type of cpu speed and cpu type detection script.  That way the

visitors to your site wont have to know if they have a fast PC or not.  They

will be sent to the version of the site that they can handle automatically.

Subject: FLASH: Frame Rates and Computer or connection speed?



  I am wondering about frame rates... The default frame rate in F5 is  15

fps.  Can the flash player installed in the computer play at any frame

rate once the file is downloaded?  Say for instance you have a wait while

loading and the movie fully loads and then starts and you set the frame

rate to  45fps...


If the actual file sizes in each frame are quite small due to image

compression, when does the fps speed start to degrade if you preload the

movie?  Only on older systems, like Pre prentium III and pre Mac G3?


Or

Is frame rate only relevant to flash swfs that play as you download them

[so cable modems can play 45 fps no problem while 28k modems will choke?]


I know you can choke the  Flash player itself  even  if you have

a fast computer system  with  heavily tweened large symbols because the

player strains to draw the graphics on screen....
