The portion of the file holding the video data. The video data might be compressed to save disk space. The data has to be decompressed using a video decompressor before you can play (see) it.

MJPEG Codec User Interface

Show in webframe

The LEAD MCMP/MJPEG Video Codec is a DirectShow® and Microsoft Video For Windows® (VFW) filter for compressing and decompressing video data using the LEAD CMP and JPEG compression algorithms. The compressed video data can be stored inside AVI files, with or without the audio data. MJPEG, which is also known as Motion JPEG, is a motion video adaptation of the JPEG standard for still photos. MJPEG treats a video stream as a series of still photos, compressing each frame individually, and uses no interframe compression.

MCMP, or Motion CMP, is a motion video adaptation of LEAD's proprietary CMP compression code. MCMP delivers smaller file sizes and can maintain better image quality than MJPEG, with the same or better image quality.

High-speed compression (intraframe only), quick random access to every frame when searching, and the ability to generate a lossless stream enable this codec to be used for wide range of applications such as real time video capturing, video conferencing, remote monitoring and medical imaging. The property page is shown in the figure below:

Changes will be applied only when filters state is stopped with the ability to set them permanently by selecting Apply or OK, or abandon them by selecting Cancel. Positioning the mouse pointer over a control displays the general information for that control.

The following table shows the controls and their descriptions:

Control	Description
Encoder Settings	This group of controls provides options for controlling encoder settings.
Enable check box	Enables or disables the encoder settings
Flip YUV check box	Indicates how YUV video data is handled. If this box is clear, then YUV video with a positive height value is handled as normal video, top side up. YUV video with a negative height value is handled as flipped video, bottom side up. If this box is selected, then YUV video with a positive height value is handled as flipped video, bottom side up, and YUV video with a negative height value is handled as normal, top side up.
Format drop-down list box	Sets the codec format. Possible values are:
	Value			Meaning
	LEAD Proprietary			LEADs MCMP format
	Lossless JPEG			Lossless JPEG
	JPEG 4:1:1			MJPEG 4:1:1 subsampling. Has a higher compression ratio than 4:2:2 and 4:4:4.
	JPEG 4:2:2			MJPEG 4:2:2 subsampling. Lower compression ratio than 4:1:1, higher compression than 4:4:4.
	JPEG 4:4:4			MJPEG 4:4:4 subsampling
Quality drop-down list box and slider bar	Sets the quality factor for compression. A QFactor of 2 has the highest quality and lowest compression ratio. As the QFactor increases, the quality decreases and the compression ratio increases. A QFactor of 255 has the lowest quality and highest compression ratio. Possible values for each format are:
	Format	Possible values
	LEAD Proprietary	-9...-1 and 2...255 where negative values represent:
		Perfect quality option 1
		Perfect quality option 2
		Quality far more important than size
		Quality more important than size
		Quality and size are equally important
		Size more important than quality - Sharp
		Size more important than quality - Less Tiling
		Max Compression, keeping quality as good as possible
		Max compression
	Lossless JPEG	QFactor is ignored for lossless JPEG.
	JPEG 4:1:1	2...255
	JPEG 4:2:2	2...255
	JPEG 4:4:4	2...255
	There is also a Custom selection. When this item is selected, the value can be selected by moving the slider bar or by entering a value in the edit box.
Interleave drop-down list box	Sets the interleave options.
	Value		Meaning
	Never		Save images non-interleaved
	When image height greater than or equal to 288 (default)		Interleave images with height >= 288
	Always		Save interlaced MJPG files
Decoder Settings	This group of controls provides options for controlling decoder settings.
Enable check box	Enables or disables the decoder settings
