BitVice is an easy-to-use standalone application based on some complex software technology designed to produce very high quality MPEG-2 video files from QuickTime movies. It works only in Intel processors running Mac OS X Leopard or later.
BitVice can do one-pass constant bitrate (CBR) encoding, which is faster, but we recommend using the two-pass variable bitrate (VBR) mode: BitVice first goes through your movie frame-by-frame to analyze each frame’s unique compression needs, and then, using your target bitrate to determine the final file size and how many bits of data each part of the video needs and allocates them for optimal quality.
BitVice produces MPEG-2 video (m2v) files that can be imported into any compliant MPEG-2 authoring or multi-plexing tool such as Apple’s DVD Studio Pro. BitVice can also extract the audio from your QT movie file and save it as an uncompressed AIFF file. Using software such as the free BitVice Helper multi-plexer, the m2v and AIFF files can be combined into an MPEG transport stream for use in DVD authoring programs such as CaptyDVD or for use on MPEG servers for presentations and broadcast.
