What is going on with Quicktime in Catalina!

Since my update to Catalina i can no longer play .mov or .mp4 videos. I've been told its from apple dropping 32bit support from quicktime but i can't see apple being this thick headed. Quicktime records video in .mov so why can i record a video and not watch it back let alone watch video codecs that most of the world uses! Ive only updated my laptop and not my mac pro which i was considering dropping back to high Sierra for Nvidia graphics support anyway. Seriously if anyone at apple is actually reading this you guys need to think about this stuff. The community was proud of you for making the mac pro modular but you keep pulling stuff again.
