Sad comment, Visualhub based on ffmpeg worked great. I gladly paid for it. Now, I guess its off to find another product.The Unofficial Apple Weblog (TUAW)
VisualHub is gone. There are no current plans to move VisualHub to open source. The underlying engine for much of the compression magic, ffmpeg, is already open-source and present in other Mac tools such as Handbrake.

The developers of Handbrake, a popular open-source DVD to MPEG-4 converter, are offering a pre-release build of the latest version, 0.9.3, on the appÃĸâŦâĸs website. The new version, which is offered as a ÃĸâŦÅsnapshotÃĸâŦÂ build and will therefore likely still contain bugs and present other issues, adds the ability to convert many different formats of video ÃĸâŦâ not just DVDs like prior versions ÃĸâŦâ to MP4, MKV, AVI or OGM files. Handbrake 0.9.3 (pre-release) is available as a free download for Macs running OS X 10.5 or later, PCs running Windows 2000, XP, or Vista, and Linux.
