	Video codec - Wikipedia, the free encyclopedia
		A typical digital video codec design starts with conversion of camera-input video from RGB color format to YCbCr color format, and often also chroma subsampling to produce a 4:2:0 (or sometimes 4:2:2 in the case of interlaced video) sampling grid pattern.
		Video codec designs are often standardized - i.e., specified precisely in a published document.
		Sorenson 3: A codec that is popularly used by Apple's QuickTime, basically the ancestor of H.264.

	TechSmith Screen Capture Codec (TSCC)
		Codecs are applied to audio, video and image files to compress their size.
		So, the video codec is responsible for compressing the video frames during recording and for reconstructing the video frames during playback.
		When a video is compressed with TSCC, anyone wishing to view the video must have TSCC installed on his or her computer.

	4i2i: H.263 Video coding tutorial
		Frames of video information are captured at the source and are encoded (compressed) by a video encoder.
		A number of video coding standards exist, each of which is designed for a particular type of application: for example, JPEG for still images, MPEG2 for digital television and H.261 for ISDN video conferencing.
		A typical hardware CODEC might use dedicated logic for the computationally intensive parts of the system (such as the motion estimator/compensator, DCT, quantizer and entropy encoder) with a control module that schedules events and keeps track of the encoding and decoding parameters.

	Codec - Wikipedia, the free encyclopedia
		Codecs encode a stream or signal for transmission, storage or encryption and decode it for viewing or editing.
		A video camera's ADC converts its analog signals into digital signals, which are then passed through a video compressor for digital transmission or storage.
		The raw encoded form of audio and video data is often called essence, to distinguish it from the metadata information that together make up the information content of the stream and any "wrapper" data that is then added to aid access to or improve the robustness of the stream.

		The algorithm of visually-lossless compression is added, that allows increasing of video compression ratio in several times (that is why the codec's version has raised in one unit).
		The next version of codec will be supplemented with visually lossless compression algorithm, where source and decoded video have some mathematical differences, but not different visually.

	IVC-H.264 Video Codec
		This new codec provides near broadcast quality video, in part, by supporting 60 fields per second (30 full frames) and an advanced method of reducing, if not eliminating, the pixelization we often see when using H.261 or H.263 video codecs when there is a lot of motion or scene changes.
		The codecs used were Polycom FX's for the H.263 video and two Polycom iPower 9000 codecs for the H.264 video.
		The video is fed into the three codecs at Site B. The three codecs are each connected to the same model codec at Site A over the lab network (FX to FX, 9000 to 9000, Minerva to Minerva).

		If you have a video file that is affected by this bug that you need to recover, install this version of the codec.
		Version 1.2.0 released on 09-11-04 Bug fixes: Fixed an error with RGB24 video that had a width which was not divisible by 4; the codec would cut off part of the top-most row of the video and compress poorly.
		This resulted from the fact that the video must have each row start on a memory address that was a multiple of 4, and padding would be added if need be; the codec did not account for the padding.
