*The article currently mentions x264 as an example of a video codec. x264 is only an encoder, so it is at least questionable whether it can be called a codec ("coder/decoder"—yes, Wikipedia allows calling a decoder or encoder a codec with its "and/or" definition in [[video codec]], but not all definitions elsewhere are so liberal, and even Wikipedia says "encoding '''and''' decoding" e.g. in [[Comparison of video codecs]]). So in order to differentiate between encoders, decoders and encoders/decoders (codecs), I would suggest changing the example to a codec library that can encode and decode. For example, libtheora (the Theora encoding/decoding library, but perhaps too obscure to be a good example), libvpx (the VP8 codec library by Google), Xvid (a popular, very well known example), or the DivX Codec (problematic as an example, because first, "DivX" is just a common brand name for the whole DivX product line, so it should be a specific product name, not "DivX", but there were several products over the years like the DivX Pro Codec etc., and second, because DivX supports both MPEG-4 Part 2 and 10, which would make the DivX example needlessly complicated).

*WebM was used as an example of a container format. First, WebM is a full file type (file format) which sets an audio, video and a container format as parts of its specification. The container format used in a WebM file is Matroska. So I think WebM is higher-level than a container format (a container format, namely Matroska, is its subset). I changed the wording to "file format", but then, it makes the example pointless and confusing. So I would suggest changing the example to a real (pure) container format like Matroska, AVI, ASF, MP4 or Ogg.—[[User:J. M.|J. M.]] ([[User talk:J. M.|talk]]) 00:02, 15 October 2011 (UTC)

**Good points. I changed the x264 to Xvid. I have also rewritten the second part. Thanks for the very helpful suggestions :). [[User:Thue|Thue]] | [[User talk:Thue|talk]] 13:22, 15 October 2011 (UTC)
