MOV often indicates a video container format (though .avi is another container – the mix is unusual, but possible if software renamed it). The number 00004 suggests it was the 4th video captured in a sequence. The word new could be:

pip install opencv-python
If you insist on using Windows Media Player or Films & TV, install the K-Lite Codec Pack (Standard or Full version). This will add AVI support for nearly every legacy video format.
