: Flash 24fps vs 30fps I inherited a bunch of Flash animations that I am in charge of updating, maintaining, editing, etc. They are really basic animations, really just sideshows of pictures

@Hamaas979

A lot of LCD computer displays are locked at 60FPS*, so 30FPS fits best, fitting one animation frame perfectly into two display frames. 30FPS should look smoother than 24FPS or even 35FPS.

Fitting non-perfect frame rates can lead to juddering effects, as some kind of pulldown method is needed.

I'd use a frame rate that's perfectly divisible 60FPS. That means 15, 30 or 60FPS.

If, like Ben suggested, you're outputting to be displayed somewhere else and/or via a file, a different frame rate might be better.

Also, depending on your needs and requirements, you may want to reassess the use of Flash at all at some point soon — Flash's future looks pretty grim as a web format.

*I believe almost all flavours of OS X and Windows use 60FPS as the default LCD frame rate. Linux can apparently use other values easily, but 60FPS is still by far the most common frame rate for computers, including iPads and iPhones.

As for the 'why':
The default FPS setting in Flash is 24 out-of-the-box (starting with Flash CS3 I think). That differs from earlier versions; maybe that's where the 30 fps setting came from.

It seems the previous person just did not think about the frame rate in the first place.

Bonus info (not 100% sure though): Once you change it in a new document and save that for the first time, any new document you create afterwards will take that new value as a default. At least that is what I remember from holding flash classes.
