FFMPEG Splitting MP4 with Same Quality

I have one large MP4 file. I am attempting to split it into smaller files. ffmpeg -i largefile.mp4 -sameq -ss 00:00:00 -t 00:50:00 smallfile.mp4 I thought using -sameq would keep the same quality settings. However, I must not understand what that does. I'm looking to keep the same quality (audio/video) and compression with the split files. However, this setting makes the split files much larger. W
