+The internal image format "ebmp" supports all color spaces. The "ebmp" files written from the [[RGB]] or [[Y8]] color spaces are standard BMP files, but those produced from [[YUV]] spaces are special and can probably only be read by AviSynth's [[ImageSource]]. This special format allows you to save and reload raw video in any [[Color_spaces|color space]].
