I do not understand why but I recorded three different things today. One was 11 minutes one was 9 minutes and the last was 17 minutes. The 11 minute file was almost 3 gigs and the 9 minute video was only about 1 gig. The odd part about it is that the 17 minute video was only about 2.5 gigs. So why was there such a difference even though the video was so much longer? I was recording a game and it didn't change. I'm currently recording with the best quality but I forget what format it is. I remember I picked the one that was best for YouTube but I forgot the name. I didn't change them in between either. Thanks for the read ^_^
