As you have sometimes checked to play a file in Quicktime format you need that player being very few other players compatible with these formats and that can view it, so the most practical is to have a tool like Convert QuickTime 2.1 which converts the formats of Quicktime (ie MOV, QT, MP4 and M4V files) to much more compatible formats such as AVI, DivX, MPEG, MEPG2, VCD, SVCD or DVD.
It allows you to process several batch conversions simultaneously as well as set the video and sound quality you want, and you can also select both NTSC and PAL mode.
You can free download Convert QuickTime and safe install the latest trial or new full version for Windows 10 (x32, 64 bit, 86) from the official site.
