Notes
• When QuickTime and an MJPEG codec are chosen, Progressive Frame must be selected in Frame Lay-
out 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.
