As a self thought animator, I thought my self animating on one's and two's. When I work in flash, I sometimes animate on one's, and I animate on two's occasionally. Right now, I'm taking an animation 101 class, and in there we do a lot of our work on two's. Now, I have no problem at all switching between animating on one's and two's. I was just wondering, how other people prefer doing there work?
I wouldn't worry about what other people are doing. Try some experimenting with your frame rates. Try ones, twos, you could even alternate between ones and twos. After enough tooling around you will find a frame rate that you like/ looks best for what you are doing. What I also wouldn't do is listen to some people in this thread that spend every waking moment on the forums talking their shit up and have nothing to show for it. Just have fun, man.
There's an interesting chapter on this very thing in Richard Williams' book: "Animator's Survival Kit". In fact, it's called "The Great Ones and Twos Battle. There's some interesting history,Art Babbitt Liked twos, Ken Harris liked ones. And suggestions, for instance,If you do a camera pan on ones with an animated character walking on twos, you can get a strange stroboscopic effect. Williams' rule of thumb, normal actions on twos, very fast or smooth actions on ones. Don't be afraid to use both.
Personally I see a difference between even ones & twos usually on faster traveling characters & items. Twos still save a "LOT" of time in animating & usually come out smooth. Still a personal preference to ones works fine... Nowa on eights....
that is another story...
To paraphrase R.A.W. here on RAW, "Animation is what you can get away with". :)
Twos with the occasional bit of 1s where needed is fine. If you're really good, you'll be able to do it on 3s or 4s or no animation at all and it'll still look and move great. :)
You want to use a combination of ones and twos. Ones are good when you need smooth action, or you're doing something that's really important and you need it to stand out, but generally speaking, twos are good enough for most things. Often times, if you do ones just for the sake of doing ones, you'll end up with floaty animation, or animation that moves so much it's distracting. Just going for smooth animation for the sake of having smooth animation isn't necessarily a good idea.
A good experiment to do is this:
Take a scene and animate it on twos . Where you see there's places you can add frames to make it look better - do just that.
THEN take a scene and animate it on ones. Wherever you can take frames out and keep the impact of the scene - do just that.
