Yes, but this isn’t a fair question. SheerVideo is a perfect-fidelity codec designed for production, interchange, and archival, whereas Sorenson Video is an approximating codec designed for distribution. But since you asked, SheerVideo compresses 20 times as fast (110 MiB/s on a single-processor 1 GHz Mac G4) as Sorenson 3 (5.5 MiB/s) at its maximum quality settings, and SheerVideo decompresses more than 4 times as fast (100 MiB/s) as Sorenson 3 (23 MiB/s) at maximum quality. Note also that SheerVideo supports alpha compression, which Sorenson doesn’t. On the other hand, Sorenson can obviously compress video far more than any perfect-fidelity codec.
