Video Settings:
Video Codec
Video codec is pre-defined in each of the profile you've selected. Usually, you don't need to change this field.
Video Size (Width x Height)
This field describes the size of each video frame in pixels, also called video resolution.
Video Bitrate (in Kbits per second)
Video bitrate refers to how much data is allocated to store motion pictures. For the same video codec, the higher video bitrate, the better video quality. Bitrate under different codecs are not comparable. Some codec like h264 or WMV9 can achieve the same video quality by using half of the video bitrate other codec requires.
FPS (Frames Per Second):
This field refers to the number of pictures displayed per second in order to form continuous motions. 24 fps is quite enough to get more a continous motion. And for portable video devices, 15 fps is all good in most cases.
