So I installed "K-Lite Codec Pack 11.8.5 Basic" so I could open MP4 files in Movie Maker, but it only opens some MP4 files.

Files encoded with "lavf57.14.100" does not prepare; only files encoded with "lavf56.40.101."

The problem is I don't see any option to change the encoder in the program I am using (which is OBS Multiplatform 0.13.1-rc1).

Any help would be apprecaited! Thanks!
