* You're highly recommended to compress your video as H.264 in MOV or MP4 format, because they are usually smaller than other files due to high compression rate.
* The compressed file size totally depends on the compress bit rate. Normally, the smaller video you want, the lower bit rate. The bit rate also controls the image quality. Please mind that the image will totally be destroyed if the bit rate is too low.
* Besides,the codec also influences the compression. Mostly you can select H.264 here.
* In most situations, a ratio of 640 * 480 is sufficient. But it also depends on your need.
* The frame rate, frame size, or codec of the source image doesn't matter so much on video compression.
Knowing the video format, ratio and bit rate that influences the size of compressed video, it'll be much easier for you to select the best video compression settings.
