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.

The global motion compensation feature is not actually supported in most implementations although the standard officially requires decoders to support it. High Efficiency Image File Format.

Most of the video compression schemes standardize the bitstream and thus the decoder leaving the encoder design 144496-2 the individual implementations.

Archived from the original on Some implementations omit support for this feature, because isi has a significantly harmful effect on speed and it is not always beneficial for quality.

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

MPEG-4 Part 2

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. Examples are mobile phonessome low end video conferencing systems, electronic surveillance systems etc. Most encoders do not support it either, and some experts say that it does not ordinarily provide is benefit in compression. The most commonly deployed profiles are Advanced Simple and Simple, which is a subset of Advanced Simple.
