The Race Pack...
...Requires the original cap pack and...
...will allow encoding of each segment just after they have
aired opposed to the original pack which required waiting
until the middle segment finished. Doing each segment after
they air gives faster encode times as it is possible to run 2
or even 3 batch commands at once. Typically by the time the
last segment is airing all other parts are done or nearing
completion. With a powerful enough computer, the entire
episode can be finished just a few minutes after it aired.
Pretty cool, huh?
