'''QuickTime Animation''' format (also known as '''QuickTime RLE''') is a [[video compression format]] and [[video codec|codec]] created by [[Apple Computer]] to enable playback of [[RGB]] video in [[Real-time computing|real time]] without expensive hardware.<ref>{{cite web|url=https://developer.apple.com/techpubs/quicktime/qtdevdocs/PDF/QTFileFormat.pdf |title=QuickTime File Format |work=Inside QuickTime: The QuickTime Technical Reference Library |publisher=Apple Inc. |format=PDF |year=2000 |access-date=5 April 2013 |url-status=dead |archive-url=https://web.archive.org/web/20000307235449/http://developer.apple.com/techpubs/quicktime/qtdevdocs/PDF/QTFileFormat.pdf |archive-date=March 7, 2000 }}</ref><ref name=wikicx>{{cite web |url=http://wiki.multimedia.cx/index.php?title=Apple_QuickTime_RLE |title=Apple QuickTime RLE |work=MultimediaWiki |date=24 May 2011 |access-date=9 April 2013}}</ref> It is generally found in the [[QuickTime File Format|QuickTime]] [[Container format (digital)|container]] with the [[FourCC]] 'rle '.<ref group="note">Three letters followed by a space.</ref> It can perform either [[lossless compression|lossless]] or [[lossy compression|lossy]] compression and is one of the few video codecs that supports an [[alpha channel]]. Supported [[color depth]]s are 1-bit (monochrome), 15-bit RGB, 24-bit RGB, 32-bit [[RGBA color space|ARGB]], as well as [[Palette (computing)|palettized]] RGB. As a result of reverse-engineering of the format, a decoder is implemented in [[XAnim]] as well as an encoder and decoder in [[libavcodec]].<ref name=xanim>{{cite web |url=http://www.math.unl.edu/~rdieter1/OpenStep/X11/xanim.2.70.6.4.2.README |title=xanim.2.70.6.4.2 README |author=Mark Podlipec |date=10 December 1997 |work=XAnim |access-date=4 April 2013 |archive-date=28 December 2015 |archive-url=https://web.archive.org/web/20151228114941/http://www.math.unl.edu/~rdieter1/OpenStep/X11/xanim.2.70.6.4.2.README |url-status=dead }}</ref><ref>{{cite web |url=http://ffmpeg.org/general.html |title=FFmpeg Documentation |author=<!--Staff writer(s); no by-line.--> |work=FFmpeg |access-date=4 April 2013}}</ref>
