.mp4 from GoPro will not import

When I try to import a movie encoded to H.264 29.97 FPS VBR (up to 32 Mbps) 1920x1080, VIRB Edit just says "Library updating 0/1" but never successfully imports the clip.

Clip is from a GoPro, encoded w/ Adobe Media Encoder.

How can I get my GoPro videos into Virb Edit? Should I encode to a different format or something?

Sorry if this has been answered; I did a bit of searching but didn't find the answer I needed. Asking may be quicker.
