BitVice MPEG2 Encoder 2.6

BitVice MPEG2 Encoder 2.6  provides you with a powerful tool which uses the latest technology and science to compress your movies into MPEG2 elementary video streams.

The video streams produced by BitVice are MPEG2 compliant, and as such, they can be mounted in any compliant DVD authoring or multiplexing tool. The BitVice is a stand-alone software and makes use of QuickTime features when it comes to reading the movie you want to compress.

Written by a few top of the world MPEG engineers, BitVice is the best real-world solution for you to produce high-end MPEG2 videos, suitable for DVD products, commercial spots or wherever you need an MPEG2 video encoding of the highest quality per bitrate available today.

Major Features:

1. Scene Change Detection and True Variable Bit Rate: The BitVice Encoder uses a two pass compressing scheme to detect certain patterns of the temporal changes in the input material.  In the first pre-flight pass, statistics concerning coding complexity are gathered. Then this data is processed and fed into the second pass, which performs the Variable Bit Rate Encoding. This means that the available bits are appropriately distributed over the different video segments such that constant visual quality is obtained. This could be done in one pass, but the effect would be suboptimal and not even near the quality necessary for demanding DVD productions. That's why the BitVice concept uses a two pass compressing scheme.
2. Adaptive GOP Structure: The structure of each GOP is adjusted according to different measures and statistics from the pre-flight pass. The BitVice does not encode an I-frame or even P-frames where not needed. This is one of the tactics, used in the BitVice concept, to minimize misplacement of valuable bits.
3. Adaptive Quantization and Bit Rate Control: Different bit allocation schemes are used for each kind of scene complexity level. Many of these schemes are unique to the BitVice. A substantial part of the research work at Innobits has been devoted to resolve the many suboptimal issues inherent in the standard, and common practice of, bit rate controlling algorithms. This is one of the most important strategies used, and incorporated in the BitVice concept, to optimize the allocation of valuable bits.
4. Special Still Picture Encoding: One of the most demanding tasks for an MPEG2 encoder is to compress still pictures. Why? Because the picture is - still. MPEG2 was designed for motion pictures, not stills. Many DVD productions of today may have several still picture segments in their "motion picture" sequences, enough to kill any ordinary MPEG2 Bit Rate Control. That's why Innobits invented a special method for still pictures encoding into MPEG2 streams.
