2. Compression artifact - Wikipedia

   en.wikipedia.org/wiki/Compression_artifact

   A compression artifact (or artefact) is a noticeable distortion of media (including images, audio, and video) caused by the application of lossy compression. Lossy data compression involves discarding some of the media's data so that it becomes small enough to be stored within the desired disk space or transmitted ( streamed ) within the ...

3. Comparison of video codecs - Wikipedia

   en.wikipedia.org/wiki/Comparison_of_video_codecs

   Each compression specification defines various mechanisms by which raw video (in essence, a sequence of full-resolution uncompressed digital images) can be reduced in size, from simple bit compression (like Lempel-Ziv-Welch) to psycho-visual and motion summarization, and how the output is stored as a bit stream. So long as the encoder component ...

4. VP8 - Wikipedia

   en.wikipedia.org/wiki/Vp8

   VP8 is an open and royalty-free video compression format released by On2 Technologies in 2008.. Initially released as a proprietary successor to On2's previous VP7 format, VP8 was released as an open and royalty-free format in May 2010 after Google acquired On2 Technologies.

5. DV (video format) - Wikipedia

   en.wikipedia.org/wiki/DV_(video_format)

   DV uses lossy compression of video while audio is stored uncompressed. [7] An intraframe video compression scheme is used to compress video on a frame-by-frame basis with the discrete cosine transform (DCT). Closely following the ITU-R Rec. 601 standard, DV video employs interlaced scanning with the luminance sampling frequency of 13.5 MHz ...

6. MPEG-1 - Wikipedia

   en.wikipedia.org/wiki/MPEG-1

   MPEG-1 is a standard for lossy compression of video and audio.It is designed to compress VHS-quality raw digital video and CD audio down to about 1.5 Mbit/s (26:1 and 6:1 compression ratios respectively) [2] without excessive quality loss, making video CDs, digital cable/satellite TV and digital audio broadcasting (DAB) practical.

7. Sorenson Squeeze - Wikipedia

   en.wikipedia.org/wiki/Sorenson_Squeeze

   Sorenson Squeeze was first announced on July 17, 2001, as the first variable bit rate (VBR) compression application for Mac OS X, [2] [3] and was released on October 29 of that same year. [4] By March 2002, Sorenson Squeeze became available for Windows OS. [ 5 ]

8. Video coding format - Wikipedia

   en.wikipedia.org/wiki/Video_coding_format

   A video coding format [a] (or sometimes video compression format) is a content representation format of digital video content, such as in a data file or bitstream. It typically uses a standardized video compression algorithm, most commonly based on discrete cosine transform (DCT) coding and motion compensation .

9. Transparency (data compression) - Wikipedia

   en.wikipedia.org/.../Transparency_(data_compression)

   Transparency, like sound or video quality, is subjective. It depends most on the listener's familiarity with digital artifacts, their awareness that artifacts may in fact be present, and to a lesser extent, the compression method, bit rate used, input characteristics, and the listening/viewing conditions and equipment. Despite this, sometimes ...
