Use this tool to generate links that forces discord to try and play a video or movie directly inside discord. By default, discord will not show video playback for video links that are too large or not in proper format. This tool forces discord to at least try.
Only sites and filesharing sites that have direct link to the video will work and play in discord. Youtube has it's own player and will not work. Many video sites will have their own player and will not work.
Video upload sites that work are sites like catbox.moe and other sites that allow direct link to video file will work.
.mkv video files will not work! HEVC/h.265 will also not work! File hosting sites like mediafire/google drive/dropbox will also probably not work!
Test area (does the video load and play? If not, it might not work on discord)
