| 2> On first run it will slice the video into video frames and create the keys folder in a subfolder named after the video. | |
| 3> Move video Keyframes over to the keys folder and edit them as needed. | |
| 4> run ebsynth to generate the out_folders. | |
| 5> Run this script again and it will merge them with crossfade as needed and output a final .mp4. | |
