This project was fun to do and was mostly to test out the new A7Sii we had just bought.  Everything was done live in one shot with just two hands on deck.  Josh handled the audio mix, and I edited and colored everything.  It was tough to try and match the A7 to the 7D and the GoPro, but we got close.  The GoPro also did not get the best lighting and was terribly grainy, after several hours of testing I was able to reduce the grain significantly and get something I was happy with.
