Notes
• When either QuickTime or MJPEG codecs are chosen, Progressive Frame must be selected in Frame
Layout to ensure QuickTime player compatibility.
• Frame Rate must be set to match the frame rate of the Composition where the generated Video file is to
be used.
• Compression allows the user to select the CODEC used to generate the new Media File(s). Depending on
the chosen CODEC, it is possible to adjust the Compression Settings.
• For full details about the MPEG Settings, please refer to the dedicated section. We recommend using only
regular Format Types in the Basic Settings dialog for trouble free operation.
• MJPEG codec - A value of 100 corresponds to an average 1/3 compression ratio, and a value of 50 corre-
sponds to an average 1/20 compression ratio.
Still Image Import
To import a single still image (not a sequence) into the Timeline, use Files > Import > Media File Browser. Use the
browser to select the image to Import and use an appropriate option to place it in the Timeline. A 5 seconds Clip
will be created from a single frame image. Alpha Channel (transparency) is supported.
AAF
VCube can import projects in AAF (Advanced Authoring Format).
About AAF
