JavaScript Reference FootageSource object 68 FootageSource alphaMode attribute app.project.item(index).mainSource.alphaMode app.project.item(index).proxySource.alphaMode Description The alphaMode attribute of footageSource defines how the alpha information in the footage is to be interpreted. If hasAlpha is false, this attribute has no relevant meaning. Type An AlphaMode enumerated value; (read/write). One of: AlphaMode.IGNORE AlphaMode.STRAIGHT AlphaMode.PREMULTIPLIED FootageSource conformFrameRate attribute app.project.item(index).mainSource.conformFrameRate app.project.item(index).proxySource.conformFrameRate Description A frame rate to use instead of the nativeFrameRate value. If set to 0, the nativeFrameRate is used instead. It is an error to set this value if FootageSource.isStill is true. It is an error to set this value to 0 if removePulldown is not set to PulldownPhase.OFF. If this is 0 when you set removePulldown to a value other than PulldownPhase.OFF, then this is automatically set to the value of nativeFrameRate. Type Floating-point value in the range [0.0.. 99.0]; read/write. FootageSource displayFrameRate attribute app.project.item(index).mainSource.displayFrameRate app.project.item(index).proxySource.displayFrameRate Description The effective frame rate as displayed and rendered in compositions by After Effects. If removePulldown is PulldownPhase.OFF, then this is the same as the conformFrameRate (if non-zero) or the native Frame Rate (if conform FrameRate is 0). If re move Pu lldown is not Pu lldownPhase .OFF , this is conformFrameRate * 0.8, the effective frame rate after removing 1 of every 5 frames. Type Floating-point value in the range [0.0.. 99.0]; read-only. 68
