Reference Software Part 5: Digital Item Part 5: Most encoders do not support it either, and some experts say that it does not ordinarily provide any benefit in compression. Scene description Part Parts 2, 3 and 9: MP4 file format Part To address various applications ranging from low-quality, low-resolution surveillance cameras to high definition TV broadcasting and DVDs, many video standards group features into profiles and levels. Archived from the original on This page was last edited on 30 Novemberat Retrieved 9 March Therefore, implementations for a particular profile such as DivX or Nero Digital which are implementations of Advanced Simple Profile and Xvid that implements both profiles are all technically identical on the decoder side.

When used, ASP’s global motion compensation has a large unfavorable impact on speed and adds considerable complexity to the implementation. Views Read Edit View history.

Most of the video compression schemes standardize the bitstream and thus the decoder leaving the encoder design to the individual implementations.

MPEG-4 Part 2 has drawn some industry criticism. The global motion compensation feature is not actually supported in most implementations although the standard officially requires decoders to support it.

Simple Profile is mostly aimed for use in situations where low bit rate and low resolution are mandated by other conditions of the applications, like network bandwidth, device size etc.
