Key frames for Animation

"Hi, this is Cable on behalf of Expert Village. For a bouncing ball animation what we need to do next is draw our key frames for the bouncing ball. We have the path we have the line that we ball would appear to follow. Now we need to figure out the timing, the basic timing. How long would this animation be? Well it is medium size ball with a average ounce to it. So we are ready to say that the animation would last 2 seconds or play back and 30 frame a second about 60 frames. Now to animate on 2 that means we would draw once piece of paper one image and photographic for 2 frames. Standard video runs at 30 frames a second so 30x20 equals 60 which is 2 seconds. Simple math is kind of essential to art you would get use to it. Without timing skills kicking in knowing that balls fall down faster and when they are at the peak of their arts of ball will appear to move slower. Just like it did in our record. This can take some practice so if it does not look right at first that is okay that is normal. So we are using our template, you can use a plastic pencil stencil if you want to. A small glass is fine for me as long as it is the same size. So it starts here and you can name your key frame or rather remember them so that is position one. And as it goes down the path, it is falling like a rolling coaster it accelerates there for our key frames would be further apart. The faster a object moves the further appear the frames would appear to be. So continue to draw our key frames."
