Cinelerra Beta 1 will be available in 6 days. It will contain the current set of features in whatever state they happen to be in on June 10 and not necessarily a debugged state. The difference between beta 1 and a backup is it's a binary you can download and install. Unfortunately this is still a native Linux program and doesn't take advantage of win32 emulation. There is no warranty, no guarantee of merchantability, no guarantee of support, and no win32 support.
