For this single day assignment you will recreate a walk cycle of at least 20 frames using an animation technique known as rotoscoping. The final file should be an animated .gif of a character walking across the stage and reappearing on the other side looping infinitely. In order to accomplish this you may need to use a reference image (option 1 below) of the main keys (key movements) and then keyframe the inbetweens. If you choose option 3 and find a .gif on Google that already has 20 frames you will not need to inbetween but simply rotoscope each frame after importing the .gif into Flash. The rotoscoping process will help you acheive decent accuracy of the body proportions, spacing, speed, and timing because you will be tracing over numerous movements creating your own frames. This is a study in body movement so try to pay close attention to the subtle changes and really learn about motion, weight, gravity, timing, spacing, etc. while you're rotoscoping. After rotoscoping the frames in Flash create an internal nested symbol of the walk cycle and motion tween it across the stage. *Do not use gradients or too many colors because .gif files are limited to 256 colors. Below are some reference images and videos to help you in the process. You should also visit Google and search for "Walk Cycle" images and "Walk Cycle, gifs" to view more animations of various creatures walking.

Here's the main key positiions.
Here's more than 20 frames including the inbetweens.
Compare the degree of smoothness vs choppiness in these examples. |
Options |
1. Import reference image, rotoscope each movement while keyframing, and onion skin them to align every frame for your nested symbol. |
(You can drag the playhead on the videos to forward or rewind through them).
Steps to Success1. Read the assignment summary, criteria, and choose which technique (option) you will rotoscope. 2. Import your image, gif, or footage into Flash (FILE, IMPORT, & IMPORT TO STAGE). 3. Lock the layer (imported content) and create a new one (rotoscope) above it. 4. Watch the video tutorial above of the option you chose. 5. Basically, rotoscope each frame, add inbetweens if needed, and create a nested symbol of all frames. (Remember to create a nested symbol simply copy the frames, go to INSERT NEW SYMBOL, and paste them on the timeline.) 6. Delete all frames from the stage (if needed) and pull out the nested walk cycle symbol. 7. Tween the walk cycle symbol across the stage. 8. Publish it as a .gif! |
