As promised when I first wrote about streaming to YouTube Live from a Tricaster, I spent some time with a Tricaster 40, after an initial failed attempt. This time, it worked precisely the same as with the 850 I originally experimented with. In fact, the preview window worked correctly as well, so I wonder if it’s a matter of simply waiting for everything to catch up before going live.
While tinkering, I noticed there was a variable amount of lag between changes in the program picture and seeing it in a test player. It went from as low as 18 seconds up to about 38.
Additionally, I discovered that while the Tricaster’s streaming configuration panel offers login fields, filling them in is not required to start the stream. What I did not check was whether the configuration panel’s built-in browser needs to be logged in. My guess is that because the stream information is generated by YouTube beforehand, no logging in is required at all, since that stream information is event-specific.
On the other hand, the modification you need to make the Tricaster’s own streaming profile, changing the keyframe frequency, is trickier on the 40 model. You can to edit an XML file, but the version of Tricaster 40 I experimented with doesn’t include a text editor in the base Windows installation. And when I installed Notepad++, Tricaster kicked up a fuss about the new application possibly compromising its ability to function properly. So plan on making that edit on another machine, and then copying the modified XML file over the network or a thumb drive.
I also played a bit with YouTube Live’s own options. You can flip among control sub-panels without disrupting the stream, but once the stream is live, you can’t really modify most of the information. There’s a thing called a slate, but all it seems to do is cover the program picture with a YouTube logo graphic. Going by the vague documentation, I guess it’s a software solution to cover up the video, whereas with a dedicated switcher you can fade to black, or cut to a graphic.
All very interesting, I assure you. Next up: an external encoder solution for 1080p streaming!
