Dallas Final Cut Pro Live Broadcast TONIGHT!
on Mar 11, 2010 at 9:54:05 pm

Don't forget, if you can't make it to tonight's meeting at AMS in Dallas, we will be broadcasting live to Ustream. Here is the link for the show:

http://www.ustream.tv/channel/final-cut-pro-user-group-dallas

The show starts at 7pm. The recorded show will be posted up in a day or so if you miss tonight.

Here's how it works. Go to the link above. The player will open and there will be a chat box to the right. If you are a registered Ustreamer, you can type in /login in the chat box. That will prompt you to login with your own user name. If you do not have an account (free), you can just type when you want to say something and you will be logged in as a numbered anonymous user. If you have any questions during the show, feel free to type them and we will get the word to Major to answer for you.

So that's it. Now before everyone goes home, log on to Ustream and create your account. It only takes a minute or two and it makes the chatting experience much better.

Using Wirecast of course?

Of course. I only had one issue last night. I was broadcasting live then switched to a .m4v. About ten seconds in, the UStream broadcast started choking. I had to stop record, stop broadcast, restart broadcast and then record and amazingly, everything snapped back to real time for the rest of the movie. Two different occasions with .m4v's and identical issues. Also, after the first hour, it seemed to be like storing up cache and this is when those problems occurred. Is there a cache issue of some kind on extended broadcasts?

[Jeff Mack] "I was broadcasting live then switched to a .m4v. About ten seconds in, the UStream broadcast started choking."
Please describe what you mean by "chocking." Dropped frames, Video froze, something else?
Was the system a laptop (which model) or a desktop (which model)?

I do think using GOP based sources add strain as they need to be decoded and then encoded in real time. I have a hunch this would be even more of a strain on a laptop than a desktop. Generally I'd convert sources to an I frame codec for best performance. It could be DV or AIC for example.

it was with a mac book pro. It had no problem playing the file at all. Matter of fact, I had the preview and the broadcast windows both open and they were identical. I only had safari open (Ustream) and wirecast. I leave my desktop configured with Wirecast open in top left, Ustream broadcast console in top right with Chat room on bottom. It was the UStream feed that was dropping frames. Wirecast settinds lot showed pushing 29.97 with 70% cpu activity but UStream broadcast went to slo mo, however the chat was still dead on.

P.S. And not having a countdown to the movies bites!

Ustream can go "funky" at times. I'm not sure why it would be on the m4v though because if Wirecast looks fine and encodes it, Ustream is getting the encode like any other source out of Wirecast. It's hard to know what or why things do happen the way they do on Ustream.

Did viewers outside of the location report seeing this issue? I've seen Flash based issues when streaming and monitoring the stream on the same computer. I've seen numerous occasions where show hosts are asking their audience if what they're seeing is OK. In an ideal world (which is difficult when doing on location streaming) one should monitor the stream on a separate computer. If you're on the same computer one can shut the browser and open it again and if it's a flash plugin issue it'll clear up. The problem with Ustream is that will also close their browser based studio and kill the stream. Livestream allows you to bypass their studio entirely so I tend to find that a bit more "safe" than Ustream when doing on location stuff.

Yes everyone saw it the same way. I did stop the broadcast like I said for 2 seconds then restarted it and since UStream was still in the buffer, it never disconnected and again, like I said, the UStream just "Snapped" back to real time. I think my overall broadcast was within a half of a second to real time.

Craig, do you work for Telestream or are you just a moderator? It would be really nice to have their user manual completely rewritten. The support staff answer questions by phone but not always timely. I was told that this product was purchased by telestream and they did not write it. It is a shame that an updated version addressing all of it's shortcomings can't be delivered immediately. Seems like they say they are working on it but it never gets fixed.
