Lower the bitrate. Using a lower bitrate will produce a much smaller video. However, if the bitrate is too small, it will affect the image quality.

If you're not sure what bitrate to use, you can try between 2000 and 5000 kbit/s.

-
Lower the audio bitrate (optional). If your video has audio, you can lower the audio bitrate to reduce the file size. 128 is the average bitrate for most audio compression. 96 will work if you don't mind a little bit lower audio quality.
