Here you go:

- The stabilized frames out of blender (with 4 blurry frames in a separate folder): https://breaking.systems/plate_frames_sorted.zip

- The original video in case you'd like to improve the stabilization as well: https://breaking.systems/plate_vid_orig.mp4

Would love to hear back in case you'll tackle it!
