Optimizing file size for animations

Hello,

I am a CC5/Iclone8 user. I have been exporting characters and their animations into UE5.7 for months now. While everything has been working, I neglected to pay attention to the size of those animation files. For context, the animations I am using are around 5-10 seconds long.

I was not expecting these animations to be 300MB to 600MB in size. Thats ridiculous ! I have tried everything with the settings to try and skinny this down while keeping them working correctly but nothing helps.

If someone can at least share a good tutorial that explains how to export animations from either CC5 or iClone8 that would be a great start. Perahps I am missing something along the way.

Thank you.
