One thing the OP said that jumped out for me-- "Is it because h.264 doesn't like my resolution? When I playblast at 1920x1080 it seems to always work."
How much choice do the users of your tool have over image size? While I'm not familiar with ffmpeg on windows, I have a memory that h.264, MPEG-4 and similar encoders can be a little finicky about image sizes and dimensions. My memory is that it isn't so much the overall size, but that the dimensions need to be a multiple of some underlying block size, like 4x4 or 16x16, though I don't recall specifics. Anyhow, if the pattern you're seeing is "certain dimensions work and others don't"-- for instance let's say supplying dimensions 1920x1080 always worked, but supplying dimensions 1921x1081 often didn't-- this may be an underlying issue you may want to look into.
