Strange issue. ffmpeg seems to be installed properly. I'll upload a file named, for example, "dr.octavius.avi"... but the title of the file will be "dr.octmp4us.avi" Also, "shedding.avi" was titled "shedd4ing.avi" And the videos would not play... the timer for the video ticks off and it seems to be proper length, but there is no video rendered. Any thoughts? I noticed that "mp4" was the string of replaced letters in the first file. Odd.
