World On Fire -- Bear Lake Day Trip

As a resident of Minneapolis sadly we're in a time where literally our city is on fire.  I considered skipping posting this week but rather decided to instead apply some of my FFmpeg knowledge to a number of day-trip media files and create a video of hiking in one of the most beautiful parks in the region.  Hoping to share some beauty in these trying times.

Took 139 pictures/videos, generated a number of video clips and panning crop filters on static images and stitched them all together using the following Makefile.

Enjoy.
