Whenever i press enter to preview the animation, it slows down (50 fps to 20 fps for example), no matter what framerate it is, and the program shows how the current framerate drops from the original (in the timeline window at the bottom). It seems to happen only with frame rates over 24...

Its not a performance issue, the program itself doesnt slow down, and my computer isnt that bad... this didnt happened with older versions of flash, the framerate was smooth. ALSO when i ctr+enter to test the movie, it runs perfectly. weird.

dyou know whats causing it or how can i fix it? :C

It is probably just lagging your computer.

CS4 is shit

It slows down on me too randomly at times. Sometimes if there's some ActionScript in the movie or the bandwidth profiler option is toggled on, it only shows about half of the movie or the animation doesn't properly match the dimensions it's supposed to be on.

But I just open the SWF file itself after publishing to preview the file and that usually works perfectly.

try reinstalling, updating your drivers, or just closing and reopening flash.

i had the same problem in flash 8, and it ticked me off.

I have the same problem. The answer is that it simply is CS4. And CS4 is a piece of crap. I also like how certain features simply dont work at all.

something that happens to me in CS3 (I'm not sure about CS4, but it might be the same thing) is that if I playback with the Q tool selected, performance is halved.

So try selecting the normal arrow tool (V) or brush or something before playback. Make sure the Q tool thing isn't selected.

My biggest gripe from the few hours I tried CS4 was that often dring playback random shape-fills you had selected still appear with the selet-dither-dotty-thing! so if I'm watching a short fbf piece playing back, every few random frames it will flash white dots cos some some frame content is still selected. There is no way out of this as far as I can tell other than de-selecting the content of these frames manully each time which is obviously so overly time consuming as to not be worth it at all

you break my fragile heart luis

Oct. 25, 2009 | 10:56 AM Wasim says:

the answer to your problem is flash 8

Oct. 25, 2009 | 11:13 AM JoSilver says:

well try changing the default framerate and see if it stays when you open a new file

I always test my movies with CTRL + Enter,
even in CS3 it kinda dicks up when I play it in the timeline.

I always have preview issues in CS4 for some reason.
While this isn't really a fix, and taking into consideration your file isn't too ridiculously large, you could just export to an .swf and do your test with that.

thats what I always do, anyway.

Oct. 25, 2009 | 2:46 PM Sho-San says:

why don't you download flash 8, is better.

and sorry i cant help.

Oct. 25, 2009 | 4:25 PM Lalo responds:

i shall do that

Oct. 25, 2009 | 3:07 PM rtis says:

your computer is just lagging do one of the following

1: Juts test movie instead of stream it through timeline

2: Click on "View" >> "Preview Mode" >> "Fast" (its like working in "low" quality)

3: Get a better computer.

Oct. 25, 2009 | 4:25 PM Lalo responds:

i had changed the preview mode to fast and it was exactly the same.

What he said

Oct. 25, 2009 | 3:32 PM rtil says:

make sure the free transform tool isn't selected

Oct. 25, 2009 | 4:25 PM Lalo responds:

same shit :C

Flash CS4 has been famous for having multiple issues when involving animation, whether it be crashing or lagging or just not working the way it should (like in your case).

I suggest you downgrade down to Flash CS3 to prevent problems like this in the future.

Oct. 25, 2009 | 5:32 PM Kevin says:

Testing the movie like that is a bad way.

Movieclips don't play their animation.

Actions don't work.

Just use Ctrl+Enter.

Oct. 25, 2009 | 5:38 PM FrozenFire says:

Yeah this happens to me sometimes too if the FPS is higher than 30

I would suggest putting a quick "gotoandplay" on frame one and just preview whatever you are working on with ctrl+enter without watching the entire thing.

I guess it depends really on how you work.

Oct. 25, 2009 | 7:38 PM Luis says:

thats not really an issue. that existed on all versions of flash. the swf generates a clean optimized version of your movie so that its able to run as you have specified (well to the best of its abilities).

Your idea of a 'preview' is not really a preview at all... you shouldnt use the main timeline to really preview your animation. It will have huge spikes in fluidity depending on how complex the frame is. Its not using any of its optimizing aspects when you are in the work window. You are never going to 'fix' that issue because its not really an issue.

Oct. 27, 2009 | 8:28 PM Lalo responds:

the thing is, it works on 8 and it doesnt work on CS4. and its very practical for previewing a small chunk of movie in the middle of the timeline without rendering the whole movie.

Also, it happens even with a tweening ball, there are no spikes of fluidity in CS4. with me, at least.

and thats my idea of preview in flash, i call it preview to diferentiate it from "testing" which is using ctrl+enter, exporting the file, etc. how else would you call it?
