When you bob in/out of water is screws the video rendering and gets a bit blocky and choppy. I could've used a higher bitrate or whatever, but TBH it's not worth the HD space. This video as it is takes up like 700Mb. I should delete the raw footage from the drive, it totals something like 110 Gb. Needless to say, I didn't use all the footage in this video, and much of it sped up to keep the video around 20min.
