  ProRes is only one of codecs using for encoding / decoding video into / from the `.mov` files container. You need other codecs, too, to be able play back all `.mov` files.
  
  The Quick Time Player is the native player for the Apple's `.mov` files, so it has its own codecs for playing back them.
  
  For Media Player Classic you need the appropriate codecs to be installed in your operating system (Windows 10).
  
  Probably the simplest and most reliable method is to download and install the free [K-Lite Codec Pack](https://www.codecguide.com/download_kl.htm) - the decision between its different versions (Basic, Standard, etc.) is up to you, all versions will cause that all media players will be able to play back all `.mov` files (and almost all others, too).
