QUICKTIME ACCESS FOR EDITING
Quicktime 4 Linux was the first convenient way to read and write
uncompressed Quicktime movies on Linux. Today Quicktime 4 Linux is
intended mainly to support CINELERRA.
Quicktime 4 Linux has the exotic colormodel support, bit depth,
accuracy, reliability, and codecs for Cinelerra, while not stressing
It includes several front ends to encoders and decoders which are used
by Cinelerra directly.
DV FRONT END
Included in Quicktime for Linux is a front end for the libdv engine. This front end
was started when libdv was really crude. Since then, libdv has gotten
better but the abstraction layer remains.
JPEG FRONT END
A parallel JPEG engine using libjpeg is implemented with a front end.
This uses 2 processors for field based JPEG compression and 1 processor
for frame based compression. It also supports some common marker
A general colorspace converter implements colorspace conversion with
nearest neighbor scaling for the large number of nonstandard
colorspaces that Cinelerra uses.
STEP UP TO THE MICROSOFT
Quicktime 4 Linux reads and writes some AVI files. AVI support has
grown over the years, since this is of course the standard on Linux,
but is continuously evolving since AVI is not consistent. Currently it
reads and writes reasonably compatible AVI files less than or greater
than 2GB. The AVI mode supports MJPG, DV, and some compressed
Quicktime for Linux won't read many of the movies you download from the
internet. Quicktime is a wrapper for many different kinds of
compression formats. The codecs we support are mainly H.264 and AAC
There is no support or warranty for the source code.
