Editing Superbit (section)

== Design ==

Superbit discs can be read by all regular [[DVD player|DVD video players]], but their film files were encoded at a bit rate that is, according to Sony, approximately 1.5 times higher (6-7&nbsp;Mbit/s) than standard DVDs (4-5&nbsp;Mbit/s), which helps minimize [[compression artifact|artifact]]s caused by [[video compression]] and allow the image to be pre-filtered less prior to compression, which results in more detail.

To maximize space for the main feature, static menus are used and commentary tracks are removed. To further improve the size and therefore quality of the film on the disc, Superbit discs contained a reduced amount (and usually completely devoid) of bonus materials, such as documentaries or interviews, which can be found on regular DVDs. All Superbit releases present the film in its original theatrical [[aspect ratio (image)|aspect ratio]].

In addition to maximizing the bitrate for improved audio and video, the Superbit line introduced seamless layer changes. Prior to this line of Sony DVDs, all dual layer DVDs caused a slight pause during playback when the layer change occurred. Some standard DVDs had their layer changes placed in scenes where they were almost imperceptible. Superbit DVD were the only optical media discs produced that had true seamless layer changes until Blu-ray was introduced.
