HOWTO: Stream Your User Group Meetings

This should help anyone who wants to get a simple public live stream setup for a meeting of any type and record segments for future use. These instructions are Mac specific.

I’ve used this setup for several user group meetings and it’s worked out really well. Here’s an example video from @commondream last year:

Setup

Configuration

CamTwist Settings

Open CamTwist. We’re going with a picture-in-picture setup that uses an entire second display as the main image displaying the presentation slides, with a smaller overlay of the webcam feed of the presenter in the bottom right corner.

Camtwist Main Window

In the ‘Select a video source:’ box on the left, double-click the Desktop source. On the far right, you’ll see some settings for this source. In that ‘Settings’ area, choose the proper screen. In our example, that screen is probably your projector or an external monitor of some sore. You’ll want to tick the ‘Full Screen’ option.

Desktop settings

Next, single click the ‘Webcam’ source in the far left sources box so it’s selected, then click the PIP button below the source list. You’ll notice a ‘PIP Webcam’ item has shown up in the ‘Step 3 Adjust settings’ list.

Highlight the ‘PIP Webcam’ item and change the settings on the right to:

  • Scale: somewhere between 0.25 and 0.5 should work well. Any larger and you’ll cover up too much of the slides. Our settings are saved at 0.29.
  • Position: drag the small black box to the area you’d like the webcam video to display.
  • Camera: select the proper camera you’re using to capture the presenter.

I leave the other options as default. Feel free to experiment.

PIP Webcam

Now, open the Preview window by selecting the Tools menu > Preview (or hit CMD+P). Check the position of your PiP overlay and drag it to a place that makes you happy using the small black box in the settings pane of the main window.

Preview

Save Settings

You can save your current settings in CamTwist by clicking the ‘Save Setup’ button. It saves quite a bit of time.

Save Settings

Once you’re happy with the output, move along to Ustream.

Ustream

Login and create a show. Be sure to add a schedule entry for the time and date of the meetings, too! Do whatever customization you’d like to get your channel hopping.

Click the big green ‘Broadcast Now!’ button on the top right corner of the Ustream site. A popup window will open (check your popup blocker if it doesn’t). Allow Flash access to your mic and camera.

Broadcast Now

Allow flash access

In the Video Source dropdown, select the CamTwist source.

Select the source

NOTE: If you don’t see CamTwist, you might need to restart your browser or open another browser.

Streaming

When you’re ready to get started, click the Start Broadcast button. Streaming starts right away, so you’re online.

Recording Talks

One of the nice features of Ustream is the ability to record segments as you stream. We typically record each talk separately so they can be embedded independently of the entire meeting.

To record a talk, get your presenter setup and ready to go. When everyone’s ready, hit the ‘Start Record’ button.

Start recording

When the talk is finished, hit ‘Stop Record’ and a new preview of the recording shows up. Click the ‘Save’ button.

Save the recording

Fill in the details and hit ‘Save.’ Now, repeat the process for the next talk and your meetings are online for posterity!

Details

Conclusion

This should help you get your meetings online to reach a wider audience. Let me know if I’ve missed anything and I’ll try to update as soon as I can.

Ben Orenstein is a Ruby buddy of ours in Boston who is teaching our vim training on Friday afternoon/early evening.

Check out this video he made giving a few suggestions for reaching vim mastery. I think you’ll find Ben is a good teacher who thinks deeply about how people learn.

It’s not too late to register, and you have ample time to register for the next session in September. Hope to see you there!
