The thing about this video is that it has a lot of motion. It is filmed in a "round about" way, circling the group multiple times, showing a group member center frame and passing by another member who ends up very large in the foreground which ends up giving the video a lot of depth. I love this because with all that is going on in the frame there is so much to take in that to get the full effect you need to watch it over and over again. The video is filmed in what appears to be a wear house of a sorts and as the video goes and the song picks up momentum they open the doors to let in slivers of light in which is very visually pleasing. Another this I liked about this video is that they showed what each person was doing at different parts in the song. If there is an awesome bass part they switched to Avi. Really cool sounding dubbing sound in the background? Kevin is there. Showing everyone's part is very important because even in a small group sometimes peoples position can be over looked. The use of shadows and darkness in the beginning shot was a very nice lead in because it gave a "what does she think she is doing?" feel which immediately hooks a lot of people because they want to know what will happen next. For the most part they were all dressed very nicely for this video; they dressed like they were going out for the night or something, but none the less they all looked good in the video. Also they all seemed to match really well!
Most, if not all, of the main aspects of video production were done very well in this video and in the rest of their videos. If you want to check them out: Pentatonix there you go! Please be sure to check out my YouTube channel here, because I am currently in the middle of producing a couple music videos with a good friend of mine who does acapella!
