Make Up Artist.mkv.mp4 -

(e.g., Windows PC, Mac, iPhone, Android, TV)

If you need to change the file to a standard .mp4 for use on a TV, phone, or video editor: Right-click the file and select Rename . Delete .mkv so the file ends only in .mp4 . Confirm the file extension change if asked.

Verify that the file size is large (e.g., hundreds of MBs or GBs) and not just a few KBs.
