Understanding common keyframe mistakes

I've been teaching After Effects for a little while, and I think I've seen every…beginner mistake out there.…It's interesting how beginners always make the exact same mistakes.…So I thought it would be useful if I put together a movie of all these little…common "gotchas," so maybe your first day in After Effects you can avoid these.…Let's say I want to animate my snowflake.…I will press P for Position, turn on the stopwatch for position, and we will…make a little animation of it moving across the frame.…Then I decide I will think I will animate scale as well.…

I will just make this smaller.…Somehow I think that this will make scale animate.…Well, if I don't turn on the stopwatch for scale, I won't have a scale animation.…So be sure to turn the stopwatch on for all of the properties you want to…animate, and of course turn on the stopwatch for the correct property.…You will be surprised how you start off animating position and you turn on…Rotation when you meant to click on Scale.…But you will get out of that habit pretty quickly.…
