Note that Compression Master was bought by Telestream (who makes Flip4Mac) and renamed Episode.
They’re two different products – Flip4Mac lets you export to .wmv straight from the FCP or Media 100 timeline. Episode is more of a traditional compression tool, supporting much deeper preprocessing, batch encoding, watch folders, etcetera. Both use the same codec underneath, so it’s really about which provides a better workflow for what you’re doing. Personally, I like the preprocessing of Episode better than that of Final Cut itself, so I tend to do my Mac encoding with that.
Also, with Intel Macs, you can also run native WMV encoding tools.
