Most animation in VFX is exported as alembic or USD and generally the skinning/bone deformations are baked down to vertex animations and sent on to the fx, lighting and compositing departments in that simplified but data heavier form. Better compression could save us many terabytes where I work, and who knows how many petabytes across the industry. Most studios use some amount of cloud rendering and the reduction in network traffic and storage with those farms would be appreciated.
