"For a long time the specifications of the codec were not public" --- Since when to when?

"This codec is now supported in FFmpeg." --- Since when? --Menchi 09:53, 11 Feb 2004 (UTC)

I belive there is more than one Sorenson codec - many sources talk about "Sorenson 2", "Sorenson 3" and so forth. A list of codecs and what they are based on would be much welcomed :-)

Sorenson the Name[edit]

Is "Sorenson" a personal name? I went to the company site, could not find a reference. --Migs 07:25, 14 January 2006 (UTC)

The CEO is "James Lee Sorenson", so I think that answers that. --Kiand 11:09, 14 January 2006 (UTC)
Thanks, I don't believe I missed that! --Migs 17:24, 15 January 2006 (UTC)

Sorenson License[edit]

Who owns the licenses of this codec now? Is it legal to use that with FFMPEG for encoding? —The preceding unsigned comment was added by (talk) 21:46, 1 February 2007 (UTC).


hello, I've seen that there was a redirection from Sorenson_Spark to Sorenson_codec. The Sorenson_codec page contains information about Sorenson Video Quantizer codec, which is not really related to Sorenson spark. I mean except the first part of its name. I think it's a bit confusing. Sorenson spark is a codec which is very close to H.263, Sorenson Video Quantizer 1 (SVQ1) is a codec of its own which can hardly be compared to any other codec and Sorenson Video Quantizer 3 (SVQ3) is a codec which can be compared to H.264.

As Apple began to move away from proprietary codecs with its embrace of MPEG-4,

MPEG-4 is no less proprietary (dozens of companies claim patent rights in it). I'm not sure what the appropriate description here is -- "non-International-Standard"? 121a0012 (talk) 03:39, 8 June 2010 (UTC)

MPlayer uses native codecs to play SVQ1 videos. Win32 QuickTime libraries are used to decode SVQ3 files.

Details aside, this section links to a disambiguation page which leads to no information vis-à-vis "piggy-backing" in the sense of one application using resources intended for another.

If a relevant article is not likely to be listed in the foreseeable future, the link should be removed.

The comment about MPlayer is not entirely correct: MPlayer can use FFmpeg's native open-source decoder to decode all of Sorenson Spark, Sorenson Video 1 and Sorenson Video 3. MPlayer can also use binary codecs to decode SVQ1 and SVQ3. --Regression Tester (talk) 11:12, 5 January 2013 (UTC)
