# Check https://youtu.be/OGKQ6krf5O0 for a demo

# Required software
# Python 3      (https://www.python.org/downloads/) (with installation: check add to PATH)
# psutil        (pip install psutil)
# pyautogui     (pip install pyautogui)

# Instructions
# 1. Open DaVinci Resolve and open the Color tab
# 2. In the tracker panel, open the Stabilizer
# 3. Make sure you can select the next clip on the timeline with the arrow down button
# 4. Select the first clip for stabilization
# 5. Open Windows Taskmanager (ctrl + alt + del)
# 6. Open Performance tab
# 7. In DaVinci Resolve click on 'Stabilize' and monitor CPU usage (in percentage)
# 8. Define a threshold of the CPU usage for when the Stabilization is in progress vs. idle
# 9. Run this script in the command prompt, preferably next to the DaVinci Resolve window
# 10. Define the Cropping ratio, Smooth and Strength values you want to change. Leave blank for no change.
# 11. When asked, hold your mouse above the input field(s) and Stabilize button.
# 12. Enter the threshold for the CPU you think is appropriate (script will move on after 5s below this threshold)
# 13. Let it do it's thing. You should monitor the first few tries.
