Added thoughts.

== Schedule Thoughts == [[User:DataGazetteer|Peter Murray]] has been asked a couple of times about the setup being used at Code4Lib. Here are those thoughts. * I'm very happy with the [https://www.blackmagicdesign.com/products/intensity Blackmagic Intensity Shuttle] devices.  Simple to use.  Built-in support for my software of choice ('mimoLive').  Diverse in the types of inputs it handles (which is good because we are usually interfacing with equipment that is supplied by an outside A/V contractor, and the variable inputs leave me confident that I can support anything that comes our way).  Moderately expensive -- $200/each, but we've used them now for a number of years so the amortized cost has been going down.  The only pain with these is that you can't seem to have both Shuttles on the same USB hub.  This works out okay because I've had one Shuttle plugged directly into the MacBook Pro and the other plugged into an external USB3 hub that also has the hard disk and the USB3-to-Ethernet dongle; that seems to bypass the problem. * Similarly, I'm very happy with mimoLive as a real-time software video mixer.  It has enough features to rival the dedicated hardware platforms that A/V contractors bring in, and it is powerful enough for our needs.  We've streamed directly to YouTube with it at 720p (1500 to 4000 Kbps) as well as an external hard drive (for backup).  Once the template is all set up, switching between sources and overlaying lower thirds and so forth happen with simple one-key keystrokes.  I'm happy to share the mimoLive template that we've used for Code4Lib the past couple of years.  It is fairly inexpensive, too -- $69/month.  One bit of advice; reboot the machine every half-day.  Last year I was using an early release version of mimoLive, and it had a bad kernel memory leak.  On the afternoon of the second day, it stopped transmitting to YouTube and the only thing I could do to bring it back was to reboot.  Next week I intend to restart the machine in the morning and at lunch to forestall any problems.  mimoLive and the Blackmagic Shuttle drivers work in normal userspace, so I've set up a separate login on my personal MacBook Pro with limited functionality.  As long as I keep an eye on it, I'm okay with others producing the stream in mimoLive knowing that they can't get access to my personal account. * Although we haven't needed them, each of the times I've done video streaming I've brought two inexpensive consumer hand-held camcorders as backups.  (One to point at the speaker and one to point at the screen showing the slides.)  I can test with that equipment at home and know that it works.  If I do ever find some incompatibility with in-house A/V equipment, I have a viable alternative to stream at least something out to the online audience.
