The title page for the second version of RealSystem Production Guide for Release 8 indicates that the guide is for "RealSystem Release 8 with RealProducer 8.5". |
RealProducer 8.5 introduces new RealAudio 8 stereo codecs, which create clips with better sound quality, especially at higher bandwidths. Only RealPlayer 8 can play RealAudio 8 clips. For a list of new codecs, see "RealAudio 8 Stereo Music Codecs".
RealProducer 8.5 uses some of the RealAudio 8 codecs by default when encoding RealAudio and RealVideo clips. These two tables reflect the new standard streaming speeds for various target audiences:
Chapter 5 has been updated with information about Flash 5. RealPlayer cannot play the Flash 5 Player format, but the Flash 5 program can automatically export a tuned Flash 4 clip, along with a RealAudio clip, for playback in RealPlayer.
Some computer operating systems limit the size of files to 2 gigabytes. Certain audio and video editing programs have implemented methods of creating larger output files. RealProducer can accept some of these files as input for encoding as RealAudio and RealVideo. For more information, see "Video Source File Size Limit".
The section "Repeating a Clip or Group" has been updated with information about rebuffering and bandwidth use when a clip repeats in a SMIL presentation.
The frequency responses of a few audio codecs in the section "RealAudio Codecs" have been corrected.
In the section "Switching Presentations for Different RealPlayer Versions", there is an uncorrected syntax error for the systemComponent
attribute. In the following syntax, the quoted URL is incorrect:
system-required="cv" cv:systemComponent="http://features.real.com/?feature
;player=6.0.7.x"
The ?feature
syntax should be ?component
, as shown here:
system-required="cv" cv:systemComponent="http://features.real.com/?component
;player=6.0.7.x"
