Legal Video Depositions with MPEG-4 Compression
MPEG-4 Legal Video Depositions
MPEG-4 treats compression differently than either MPEG-1 or MPEG-2. MPEG-4 legal video depositions offer higher image quality with smaller file sizes than either MPEG-1 or MPEG-2 video depositions. MPEG-4 compresses files in a range from 5 Kbps to 10 Mbps making it adaptable for delivering video depositions to everything from cell phones to HD quality output. Instead of interpreting each individual frame of a legal video deposition, MPEG-4 compresses images by reusing the image information without throwing away as much image data. In addition to Wisconsin legal video depositions, MPEG-4 is commonly used for DivX movies.
MPEG-4 Legal Video Depositions, Summary
MPEG 4 encodes much more efficiently than other MPEG formats. If you encode using the same settings some footage to MPEG-2 and to MPEG-4, MPEG-4 will beat it every time for file size and, possibly, image quality. Even with an MPEG-2 file at almost double the bitrate of a MPEG-4/DivX file, the sharpness/clarity on a frame containing fast motion will almost always win with MPEG-4.
