Exporting Animated Mask for Use in Blender?

Question

Hi, I am trying to figure out if there is a way to use the Auto Mask feature in AE and then use that resulting mask in Blender. For instance, I am trying to learn node based compositing in Blender, and would like to create a mask for an image sequence. I can readily create a mask in AE and can use its auto mask feature and would be great to have a way to use it exported from AE. Figure there must be some standard way to do this? I guess it amounts to outputting the mask as something like an alpha only EXR image sequence?

thanks

For Alpha only there is no need to create bloated EXR files. You can render an 8 bit PNG or TIFF just as well most of the time and if you need more transparency levels ramp up to 16 bit TIFFs. Even in scenes with glass there is rarely ever so much transparency info that would require more. Other than that, yes, simply render the clips using the Alpha only option in the render settings.
