My group was Annabel, Katie, Lauren, and me. We didn't really need to discuss which sport we wanted to make our video. All four of us play volleyball, so that was the sport we chose. We started filming our project about 2-3 weeks ago. At first, we filmed each other passing the ball in slow motion to make sure we got the correct form down. We got a lot of our filming down within the first couple of days. We then started editing all of the little clips together and added the music. Doing all of the calculations took some time but we managed to do it all within a day or two. We also made voice recordings to play over the time lapse video of a Junior Varsity volleyball game. After we added the finishing touches to our video (including some bloopers) we stopped editing it and posted it on YouTube.

Reflections
This lab really taught me a lot about how I can improve my passing skills. This past season, I was a defensive specialist, so learning how to improve my passing techniques was really good for me. Not only did this project benefit my passing skills, it was also beneficial to my teamwork skills. Working with the people I worked with for this was a really good experience. They were all very supportive for each other's ideas and were also very cooperative with one another. Communication was very helpful in this. We were able to communicate our ideas and other thoughts on what we were missing in the video and what else we needed. Over all, I enjoyed this project very much and I loved the people I was able to work with.
