And I’ve never seen a problem with compressed files larger than originals – you need to back that one up with motion footage sequences. Uncompressed anything 6K and 8K frames are massive and would have broken workflows if LZW  compression does not work.
 

I can see how LZW might work OK for mograph elements on a back background, but otherwise it’s just not a good algorithm for real-world footage.  I just googled it, here’s the first link that came up.  Note the file size comparison at the bottom as well as the cautionary note:


LZW works fine for 8 bit, just not 16bit images.
