i've also heard that another common frame rate is 15/s. will i a significant difference in video quality. also when i rendered (at 24f/s, before i posted the question, the file was absolutely huge and various programs had trouble playing it. 13sec animation was about 1.2gb. the resolution was a bit high, because i didn't look at the render properties after i incresed the resolution to 150 dpi. will returning the resolution back to normal help significantly?
