Video editing and modeling/rendering effects are completely different toolchains. Tools for the former are still very crude compared to what's available on Mac/PC. Support for the latter is good on Linux, probably thanks in large part to the Unix legacy imparted to the effects industry by SGI.

But a lot of the Linux machines you see in VFX shops are just headless render nodes. People doing the creative work often use Macs or PCs.
