Re: FLASH: (tech) AUDIO/SYNC with ANIM: help PLEASE

[Randy Kato]

CJ,


As you've noticed, syncing audio and animation is not one of Flash's strenghts

since how the movie plays is dependent upon the target machine. With a heavy

animation (like yours with lots of bitmaps and alpha tweens -- especially at

full-screen), the processor is already taxed and causes a situation where the

sound might play at normal speed where the animation is chugging. This is with

it set to 'event.'


Using 'stream,' the way I understand it tries to get the audio and anim to play

together, but at the cost of altering both. Stream uses markers (not sure what

the exact term is) in each frame to control the streaming, so it adds quite a

bit of file size as well.


We've had good success using the event setting with a couple of other

techniques. Of course, optimizing the animation so that it's as smooth as

possible is one. The other is to try breaking up the sound, if possible. For

example, if there are breaks in the sound you can use shorter clips and start

them in the exact keyframe where it syncs up with the anim. That way, if the

anim plays too slow it won't fall out of sync too far before it hits another

keyframe where it matches up again.


But unless I'm missing something, your audio doesn't really need to "sync"

right (I checked the exe)? You're just concerned with length? If that's the

case, loop the sound. You could probably get away with a very small clip that

loops and save a lot of weight.


As for your other concerns, converting the bitmaps to vector would be a good

idea, but you should re-create them in vector rather than using trace bitmap.

Most of them look like they could easily become vector graphics.


Also, if this is playing directly from a hard drive, then pretty much any

slowdowns you see are due to the Flash movie being too complex for the target

machine. No need for a preloader since the whole file is already fully loaded.


HTH,
