Why Plex Can not Open MP4?

Generally, Plex can play MP4, MKV, AVI, MOV, DIVX and many more other video formats, but if the video format is successfully played via Plex depends on what device you are using Plex on. For example, if you are using Plex on PS4, you can only use MP4 with h.264, hevc video codec and aac, ac3, eac3 audio codec. If you are using Plex on PS3 you can only use MP4 with h.264 video codec and aac audio codec. That is to say, you can not play MP4 with video codecs other than H.264 and HEVC and audio codecs other than AAC, AC3, EAC3 on your PS4. And you can not play MP4 with non-H.264 video codec and with non-AAC audio codec on your PS3. Besides, the MP4 resolution also needs to comply with the required ones to allow the compatible playback.

Good news is that in most cases Plex will transcode your MP4 file with the unsupported video codec, audio codec, resolution, etc to your device supported ones, but in some cases you will receive message 'This server is not powerful enough to convert video' which means that your MP4 file can not be transcoded by Plex to your device supported MP4 and the MP4 file can not be played normally on your device.
