VBR-Supported Features
The VBR-supported features in QuickTime 4.1 include:
-
opening and importing of both CBR and VBR encoded MP3 files.
-
editing of local movies containing MP3 VBR sound tracks, using standard cut, copy, and paste operations.
-
saving movies containing VBR sound tracks, either as self-contained or non-self-contained QuickTime movie files.
-
exporting from an MP3 VBR compressed sound track to any sound format for which QuickTime has a compressor. This includes exporting to WAV, AIFF, snd, .au, AVI, DVC, and any other format supporting sound.
-
fast-starting of MP3 VBR files.
There is also support of MP3 VBR audio for streaming. Features include:
-
hinting of movies containing VBR sound tracks
-
streaming of MP3 VBR sound data to VBR aware clients
Note
In the descriptions above, MP3 VBR should be considered to be interchangeable with "a VBR audio format." Initially, VBR support is provided in the MP3 decompressor. In future releases, additional support will be provided for other VBR sound formats.
