Before I could animate anything, I had to configure my frame rate and animation time. All that really did was make my FPS (frames-per-second) 15 and my total frame 75, meaning the animation would play for five seconds and then stop or loop. Didn't affect my animation much other than how much time I had to work with.
Not much. When going back to edit keyframes, sometimes I'd change them outside of keyframe model, which affected the whole object, but that was a minor annoyance. When going back on a keyframe, I just need to go into keyframe mode, and then edit the model, then make a new keyframe to overwrite the old one.
The frame rate didn't affect my animation's smoothness much; since I spaced my frames out and gave the program time to ease them. My only issue was when I made the green tube skid, as I originally had the frames to close together, and had three. This issue was easily solved by spacing the frames out and only using two.
I used the "set keyframes" mode, as it just seems easier to use. I can transform my objects however I want, and set a keyframe whenever I want, and the program won't interfere by adding a keyframe where I don't want one just because I paused for a second.
Well, though we haven't yet learnt how to rig character models, the basics of animation here will certainly help when making animations for characters, environments, objects, etc. Knowing how to make and use keyframes and edit frame-rates is certainly the most useful part, since it's the very basis of animation. Not really much to say other than that the basics are useful for learning more advanced techniques. Who could've guessed.
