Video Frame Rate: Video frames per second.
The more frames per second,the smoother the motion and the more data is required to transfer per second.
Video Size: Height and width of the video frame. The bigger the frame
size, the more data required to transfer per second.
Video Key Frames per Second: Key frames are fully rendered frames that
are inserted at specific intervals. The more key frames, the better the
video quality and higher the data transfer per second. Note that most of
the newer CODECs now offer automatic key frame insertion. This process
automatically detects a scene change and inserts a key frame at the
beginning of the scene. This lowers the overall amount of key frames
required and lowers the overall data to stream the media file.
CODEC: This is the software compression component which compresses and
decompresses the audio and video - Note that each new CODEC version
continues to improves overall quality of streaming and lowers the data
required to render quality audio/video at large frame sizes and lower
delivery rates. CODECs are created for either video or audio
compression. Audio CODECs are optimized for delivering two types of
content: voice or music. Each optimizes the sound quality of the content
while minimizing the bandwidth required to stream the content.
Audio Delivery rate: This is the size of the data allocated to the audio
stream. The higher the delivery rate, the better the sound quality and
more data per second.
Audio Sample Rate: This is the frequency of audio samples that is rated
in kilohertz. The higher the kilohertz, the better the sound fidelity and more
data per second.
