It seems like maybe there's a problem with your original file. I'd recommend trying another file to see if you have the same issue.

what file, my mp4 file

[davidarbor]

Yes. It's hard to say and you're not providing a lot of information, but typically, if you can't convert your file from one to another, there can be issues with the source file. There's nothing particulary special about converting from h.264 to ProRes, it should just work.
