Importer returned bad result - Error 99

Trying to create an H264 with AME. When using a Match Source setting it works, but if I attempt to resize the video (to 1280x720 for example) it fails with the following error:

Export Error
Error compiling movie.

Import Error

Importer returned bad result.

Writing with exporter: H.264

Any help?

Running AME on a Mac w Yosemite. I am exporting a batch to h.264. I've done this many times without any problem. Today I had to run two files. Both source files are self-contained ProRes HQ files. They are both being exported to h.264 -- one is standard def 4:3 and the other is is widescreen standard def. The 4:3 file rendered properly, but AME fails on the widescreen file. I am using a setting based on the widescreen DV preset and modifying it.

Here is a copy of the ErrorLog:
