Help Using Help Reference Back 91 Type Floating-point value; read/write. FootageSource displayFrameRate attribute app.project.item(index).mainSource.displayFrameRate app.project.item(index).proxySource.displayFrameRate Description The displayFrameRate attribute of FootageSource corresponds to the effective frame rate as displayed and rendered in compositions by After Effects. If removePulldown is PulldownPhase.OFF, then this will be the conformFrameRate (if non-zero) or the nativeFrameRate (if conformFrameRate is 0). If removePulldown is not PulldownPhase.OFF, then this will be (0.8 * conformFrameRate), the effective frame rate after removing 1 of every 5 frames. Type Floating-point value; read-only. FootageSource fieldSeparationType attribute app.project.item(index).mainSource.fieldSeparationTy pe app.project.item(index).proxySource.fieldSeparationTy pe Description The fieldSeparationType attribute of FootageSource specifies how the fields are to be separated in a non-still footage. It is an error to attempt to write to this attribute if isStill is true. It is an error to set this value to FieldSeparationType.OFF if removePulldown is not PulldownPhase.OFF. You must instead change removePulldown to PulldownPhase.OFF, and then set the fieldSeparationType to FieldSeparationType.OFF. Enumerated Types FieldSeparationType (read/write); one of: NONE UPPER_FIELD_FIRST LOWER_FIELD_FIRST FootageSource guessAlphaMode() method app.project.item(index).mainSource.guessAlphaMode() app.project.item(index).proxySource.guessAlphaMode() Description The guessAlphaMode() method sets alphaMode, premulColor, and invertAlpha to the best guesses for this footage source. If hasAlpha is false, no change will occur. Parameters None. Using Help Back 91
