Edit the original files (affinity designer: .afdesign -- or -- adobe: .psd) and export each as png.
*note: files were created with Affinity Designer (https://affinity.serif.com/en-us/) and exported as .psd for adobe compatability. adobe's layer effects are different, thus for each bud-shape you will need to adjust the inner shape's fill to be transparent and/or match the background.
Duplicate the unaltered logo (00.png), rename to 99.png and duplicate 30+ times. total frames ~50.
Install ImageMagick:
