getNativeAspect(clip)

Additional Notes

Native Clip version of AspectOf

Like getNativeSize, this undocumented function was discovered in FCP4's Widescreen filter. It does the same thing as AspectOf, except it reports the native pixel aspect ratio of a clip instead of dest's pixel aspect ratio.

This seems most useful for mixing 16x9 wide clips with standard 4:3 clips. GetNativeAspect does correctly report the pixel aspect ratio of PAL clips in NTSC timelines, but those clips are still hamstrung by differeing frame rates.
