The bitrate that you choose determines the quality of your video
and the file size. The standard units for bitrate is bits per
second, or bps. Sometimes bitrates are expressed in Kbps
(kilobits per second) or Mbps (megabits per second). Do not
confuse Mbps and Kbps with MBps and KBps. A lowercase 'b' refers
to bits, an uppercase 'B' refers to bytes. From your question it
seems you are more concerned about size than quality, so I
recommend that you pick what is a reasonable file size and
deduce the bitrate that achieves that size. For example, let's
say you want your file to be 200MB. First convert this size to
bits: 200 x 1024 x 1024 x 8 = 1,677,721,600 bits You also said
that your video is 11 minutes, which is 660 seconds. So now we
obtain the bits per second: 1,677,721,600 bits / 660 seconds =
2,542,002 bits per second (approximately) From the above, you
know that if you pick a bitrate of 2,500,000 bps (same as 2,500
Kbps or 2.5 Mbps) then your file will end up being about 200MB
in size. So now what's left
