Video frame size – the parameter defining the size of the video frame recorded in video format. Just like with the pics where this parameter is called "resolution of the image", this parameter is characterized by the number of points (pixels) down and across.
Video Bitrate – the parameter representing the speed of transfer of video information bits. Video Bitrate is used in the process of measuring the effective speed of transfer of information in a digital channel. The speed of video data transfer related to the total bandwidth is measured in bauds.
Audio Rate – audio parameter associated with the frequency of the sound flow received as the result of playing or recording. The highest sound frequency which is also considered to be optimal for human perception is 44.1 KHz. It ensures the most pleasant sounding of the audio information.
Audio Bitrate is defined by the speed of transfer of data (audio information) bits through a channel. Audio bitrate is used in the process of measuring the effective speed of transfer of audio bits through a sound channel. This parameter is measured in units called bauds.
