What is the FourCC : FLJP about? This is a field encoded motion JPEG with an LSI bitstream format. You can download the codec here : FourCC : FLJP.The Morgan LSI Bitream codec is on this website.
FourCC : FLJP
You will note that this codec was developed by Morgan Multimedia. The FLJP codec is a variant of the Motion JPEG (M-JPEG) video codec. You will note that the M-JPEG codec compresses video as a sequence of JPEG images. This is very similar to the FFV1 codec which does the same. It compresses the video frames one at a time. In this way searching for frames does not depend on the frame sequence. This is mainly used for video editing and production. Since it is very efficient in storing a small file. So with this the video storage becomes cheaper as the files are much smaller.
The FLJP which is a well-known variant of M-JPEG uses a 4:2:2 chroma subsampling scheme. The reason for this is for the high colour scheme of the video. Colour reproduction when compressed does not always give a good end result. There is also support for interlaced and progressive video. The frame rates as well as the resolutions are wide enough for everyone, both amatuer and professional.
The M-Jpeg was very common when multimedia started and became mainstream. This was the codec in use with the M-Jpeg. See also the Morgan M-JPEG codec as well as the features of Jpeg 2000. There is also the DIV3 and DIV4 video options.
