Supported features for AMX export

When creating compositions intended for the AMX format, note the following:

Blending modes

Only Normal mode is supported.

Layers and switches

Layers beneath an adjustment layer or beneath a layer using a blending mode other than Normal are combined and rendered as a single layer. 3D layers are also combined and rendered as a single layer. All layer switches except the following are supported: Adjustment Layer, 3D Layer, Preserve Transparency, and Motion Blur.

Rectangular pixels

Rectangular pixels, such as those used in DV and D1 video formats, are converted to square pixels upon export.

Keyframes

All Hold and Linear keyframes are retained, but all Auto Bezier keyframes are interpreted as smooth. All other keyframe types, such as keyframes to which you have adjusted the velocity, cause the exporter to sample the range between the adjusted and unadjusted keyframes and then to create a linear keyframe for each frame of the animation. Roving keyframes are not supported.

Masks

Only masks that use the Add mask mode are supported. Mask Feather and Mask Expansion are not supported.

Mattes

All mattes except traveling mattes are supported.

Effects

Path Text is the only supported effect (however, its Fill Over Stroke and Difference options are unsupported). Only one effect per layer is supported.
