I recently came into possession of Flash and there are some things that are confusing me.
1) What's the difference between key frames and just frames?
2) What's the purpose of converting something to a symbol?
1) A keyframe is a new frame. Its like, not the same. A regular frame is a copy of the previous frame.
I understand what you mean but its kind of a confusing way of putting it for someone new i think.
A KEYframe to me is a frame that forces flash to process it fully, in other words it tells flash hey this frame needs special attention ie you're introducing something new in terms of art/actionscript/whatever. As a time saving feature, you can push F6 and create a keyframe with the art from the previous frame carrying over. This makes it easy for making light tweaks and changes, its a fairly popular technique associated with 'fbfing' frame-by-frame animation.
When you create just a frame. You are telling flash that this frame has no need for special attention or extra processing... and so through the beauty of flash, it will save on filesize by simply carrying the information that it process on the first instance of the keyframe. Background art is typically suited for that type of handling. The thing to remember about a frame is that since you are not creating a keyframe, you are basically dealing with the same art all along. Meaning that extending that frame across your timeline and then adding more art to it will affect every frame on that layer (until it runs into a keyframe)
I dont know if that explains it a bit more.. its a difficult concept to grasp at first. Hang in there
