Quick look stopped working

[isifoo]

does anyone know why apple stopped supporting quick look for files like QuickTime animation?
It's on of the best things that OS X had
Without it it's no better then windows

What file types are not working? After reading your post I tested a .mkv, .png, .jpg, .rtf, and a .mov file with the Quick Look feature.. and all are working perfectly. What file type are you attempting to utilize with Quick Look?

 

[isifoo]

files that are not supported are quicktime files (.mov) with animation codec
most of my video assets library is in this very common file format

I tested these features against all sample file types Apple offers here. https://support.apple.com/en-us/HT201549

One of them is an MOV with Animation Codec.
All sample files are fully supporting the Quick Look feature.

Sounds like you are having an OS issue...
