This is the first processing run of the total solar eclipse video shot on Monday 2017 August 21 south of Jay Em Wyoming. We used Movie Maker that comes with Windows 10, and it was able to stitch together the six compress .m4v files created by Handbrake from the original .mpg large files. We added in some public domain background music and were able to speed up the partial eclipse phase x64 times, then move back to x1 normal speed for totality and back up to x64 for the post totality partial phase.

It did take some time to process on an Intel Core2 Duo @2.93GHz and 4GB RAM working on an SSD drive. On the order of an hour give or take.
The video is quite large (80MB) and does contain some gaps where we suffered equipment failure.
