MXF Files not appearing in the preview in render queue.

Hi all,

First time posting here so forgive me if I foget to include any relevant information.

I have a feature film exporting with the render queue, a lot of footage with .MXF files and others with .MOV files. When rendering in the render queue, the .MOV files preview back perfectly fine, but the .MXF files just come up as a black screen. Then, when another .MOV file comes up, it looks totally normal in the preview for the render. I've been rendering for about 111 hours now and with a release coming up I want to see if I will have to redo my render if the MXF files cannot be rendered directly in After Effects.

Thanks very much.
