  Going Live with Avid Xpress Products

  Posted by Sbtvnk26 on August 16, 2005 at 2:26 pm

  OK, here’s a good one for all of you.

  I have a person in my office that insists that we can feed to the internet semi-live (a 60 to 90 second delay)through Avid Xpress Pro and/or DV. I have been searching for a yes or no answer for the last few days and haven’t found a definitive answer and I’m hoping someone here can help.

  What we want to do is shoot in our studio through a switch into our avid xpress system, in 60 to 90 add lower thirds and fix any flash frames, render and output to our external encoder to stream to the internet. That part I know we can do, but this is the part that stumps me. Doing the whole thing while the footage is coming into the timeline and outputting, with the delay, out to the encoder at the same time. Does anyone know if this a possible with an Xpress system?

  Thanks

  You appear to be asking about “chunking”, which is the ability to play out media while a clip is still being digitized. I don’t believe Avid Xpress Pro will support this, but it’s possible that one of the news products will. A non-Avid NLE like Editware’s FastTrack connected to a server will do this. ESPN has been using this system.

  Sincerely,

  I very much doubt it unless you have multiple edit systems. While ever you’re working on the timeline adding effects, edits etc, there is no ‘streamed’ output. All effects require rendering as you are changing formats for output.

  The ‘News’ Unity and LANShare products allow playback/editong while still ingesting (chunking) on separate machines but you still need to add effects in realtime and then compress the output for the web stream.

  Not sure quite if this is what you are after but the Leitch VelocityQ editor and the Quattrus card will allow you to stream your timeline as WM9 as you are playing it. I could never find a real use for it but it was a great demo 🙂

  Perhaps you have found a use for it?

  The other way to go would be to pop the DV output of the Avid Xpress into another PC and run Windows Media Encoder on it and stream it that way
