A couple simple scripts to turn a video into a long exposure or star-trail. Theres's a few commented out lines which can be used to create an additive video of the time lapse.
They're just python scripts. In detail:
- Install python 3.x
- Install python's imageio library: (
python -m pip install imageio) - Run the .py script with the video as the first parameter, and the output image as the second (
python <script_name>.py <video-file> <image-to-be-created>)
