Play mp4 video on Panasonic TV

Supported Format AVI/MKV/WMV/MP4/M4v/FLV/3GPP/VRO/VOB/TS/PS, MP3/AAC/WMA/FLAC/WAV, JPEG

When I play mp4 video, some play some don't

Is there any converter to convert in format supported by TV?

@tech_help, were you able to solve it? I think mp4 (like mkv) are containers. They may contain any video stream encoded with a format (like x264, x265) and audio (like AAC, TrueHD, DTS-HD etc). I assume you tried to connect a USB to play the file. You could try
a) Install and use plex app on tv.
b) Plex app on some streaming device like fire tv stick.
c) Re-encode video using some tool like handbrake.

b) would be my choice.

I used ShanaEncoder but it creates huge AVI file
