[QUOTE="JoePlumber, post: 330018, member: 83882"] YUY, YUV, RGB ? YUY2 stores color data at a lower accuracy than RGB but we don't really notice any detail loss. Chroma sampling is half the vertical resolution. YV12 is similar to YUY2 but there are even less chroma samples (fewer bits, less space used). MPEG1, 2, 4 all use YUV (YV12). Examples, DVDs, Mjpeg and DivX supports 4:2:0 YUV (YV12) color. Most video editing programs work in RGB32 (24-bit color) or RGB24 (8-bit color) because it's easier to work with. The video editor has to convert your video from YUV to RGB which slow things down and can cause detail loss. Colorspace conversion is bad! However, Premiere Pro can support 4:4:4 uncompressed YUV, which is same as RGB. Solution: use AVISynth for any video editing work because VirtualDub never touches the incoming video stream. :) [/QUOTE]
