The Microsoft Media Foundation encoder for H.264, which we are using in our importer, has a limit of 4096x4096. The source webm clip being used has a resolution of 5000x2812. Because it contains transparency, the resulting stored resolution for H.264 ends up being 10000x2812. Using webm directly, or using a lower resolution of this clip are two alternative that would have to be tried.
