How to Produce a Webcast… part 5

Video Mixer

In part 4 of my how-to series, I spoke about mixing various audio sources together.  In this one I will describe how to mix your various video signals together with the mixed audio to produce a final product.

Once again, due to intensive research, I discovered a wonderful product which does exactly what I’m after.  According to their website:  “VidBlaster is a state-of-the-art live video production tool” and I would totally agree.  This single tool replaces tens of thousands of dollars worth of physical video mixing equipment into one very easy to use piece of software.  When used on an appropriately fast computer, you can produce Full-HD LIVE broadcasts. 

During the first episode of Week In Review, we had spent too much money on needed audio and video equipment that we were broke.  But by our second episode we had enough capital to purchase the Home version of VidBlaster.

As you can see from the image on the right, our home version limits us to 7 modules.  Based on the hardware we have, here are the seven modules we chose and why:

  1. Preview allows us to monitor the signal output.  This is similar to the “headphones” connector on our audio mixer.  Since we want to produce a 720p broadcast, our preview window is sized appropriately.
  2. Audio is a module which we designate the audio source that will be feed into the broadcast.  I have chosen the rear Line In blue plug on my sound card since that is where I have the Main output of the mixer going.  We can monitor the sound level with this module and modify it as needed on the fly.
  3. Streamer is used to link our broadcast to our uStream LIVE broadcast channel.  It only has Start/Stop buttons with additional options under the right click menu.  These include our username/password and our chosen LIVE broadcaster (uStream in our case).
  4. Recorder, this module is used to capture our broadcast to a video file for later post-production within Windows Live Movie Maker (covered in part 8 of this series).  This module also includes some basic controls for starting/stopping and saving our broadcast.  It also has an option for uploading the video, but I want to add starting and ending credits which I do in post production because of the Home Edition of VidBlaster I own.  Once we have enough to purchase the Professional Edition we can add our starting and ending credits within the live broadcast itself.
  5. Camera 1 which I have configured to pull from the Microsoft Cinema camera pointed at David’s location.
  6. Camera 2 is configured to pull from my other Microsoft Cinema camera which is pointed at my location.
  7. Camera 3 is configured for Screen Capture mode.  Since we have the 7 module limitation this module changes based on how our broadcast is planned.  Currently our co-host Eric doesn’t have a computer and we are using our Skype to call his cell phone.  This configuration allows me to display YouTube videos, websites, or anything else I can call up on it on a LIVE broadcast.

Our upgrade plan is pretty easy to guess.  The Professional Edition of VidBlaster increases the module limit to 25 and with these additional modules we will be changing the configuration and adding new modules.

  1. Camera 3 will be configured to screen capture mode and has our Skype caller displayed full screen.  They are displayed on my 3rd desktop screen which points towards David so he can see our guest directly.
  2. Camera 4 will be pointed at my 2nd desktop screen also in screen capture mode.  This 2nd screen will be used for browsing webpages and such LIVE.
  3. Player 1 will have our opening credits video which was post-produced a few weeks ago.
  4. Player 2 will be used for our closing credits.  Likely these are produced for each episode since we don’t know who to thank for various content and our guests.
  5. Player XX, these additional players will be used for various videos used during the broadcast.  If we want to display a YouTube video, we will use a utility to download that video and have it on my hard drive and preloaded into a Player module.  The reason for this is it will put less of a strain on my internet connection which every bit of is needed for a good quality upload to uStream.
  6. Video Overlay 1 will be used to hold our customized title graphic for David.  It basically contains his name and job description for display at random times during the broadcast.
  7. Video Overlay 2 will be used for my customized title graphic.
  8. Video Overlay 3 is destined to hold the customized title graphic for our Skype guest/co-host.
  9. Video Effect 1 I will use to combine both Camera 1 and Camera 2 in a side-by-side or Picture-in-Picture format.  This module has nearly a dozen different formats which I may setup additional Video Effect modules for.
  10. Video Effect 2 is used to combine Camera 2 and Camera 3.
  11. Video Effect 3 is for Camera 1 and Camera 3.

As you can see, our limitations force us to find creative ways to produce our broadcast.  If you’d like to help us overcome these limitations, please donate to the Week In Review show.  All donations will go to improving the quality of the show and keeping us online and broadcasting.

How to Produce a Webcast… part 2

Video Cameras

We got off to a good start with my previous post (part 1) about choosing the right person to Host our webcast.  In this post, I’ll talk about the camera I’m using, why I chose it along with upgrade options we’re looking at if the show really takes off.

For the start of our new show Week In Review I chose to use the Microsoft LifeCam Cinema for a few reasons.  image

The first and most important for any new venture is price.  I took a trip down to my local Wal-Mart, I live in NWA and there’s a Wal-Mart every 10 miles… literally, and browsed around the electronics department.  No one in NWA can beat them on the price point, although everyone can beat them on selection when it comes to computers and computer accessories.  Anyways, I picked up two of these cameras at the low low price of $79 each.  I was under a time constraint and with the launch of the show just weeks away, I wanted time to configure, confirm and possibly return if necessary whatever I chose to sue.

The second reason for this selection is the widescreen High Definition video it produces.  I wanted to produce a high quality 720p video production and our local options are limited.  I did my research online and of the options I had the LifeCam Cinema fit the bill.  I brought it home for testing and everything worked better than expected.  The video was so crisp and clear I had to go change my shirt cause I noticed I’d spilt some of my lunch on it earlier today.

imageHere is an image of my first test.  It was directly being compared to an old webcam I was using before and demonstrates the higher quality of the broadcasted image.  Click it to view it larger and see the clarity the LifeCam Cinema provides over my older HP standard definition webcam.

The next qualification for this camera was if it would be compatible with the video mixer software I chose called VidBlaster.  I’ll go into greater depth about this software in part 5 of my series.  On a side note, the video mixer software can only accept one audio feed.  This meant that if I was using more than one camera, I could not use the microphones from each.  As a result I needed to buy an audio mixer in order to supply the mixed audio from multiple sources.  I’ll discuss further about the audio mixer in part 4 of my series.

During my research I discovered many options available for supplying the video I want.  Some were much pricier than the option I chose, however some of these are in my upgrade plans if the show takes off.

A possible upgrade path for our video equipment will include a few different pieces.

HD Camcorder:  The one I’ve researched with a reasonable price range for ourimage size production is the Canon VIXIA HF R20 Full HD Camcorder.  This $340 camera has the HD quality we’re looking for and the portability we’d like to add to the show.  We can use this portable camera to film events, then play them during our LIVE broadcast and edit them in during post-production.  Combine this with the compatible WM-V1 Wireless Microphone and we can capture HD video and audio easily when remote on location.

HDMI Capture Card:  This PCIe computer card will convert the HDMI computer signal from the camera to digital video imagethat VidBlaster can use as a video feed.  The device I’m looking at is the Blackmagic Design Intensity Pro HDMI card.  At $189 at the time of research, this price fits perfectly into a reasonable upgrade budget.  Other options on the capture card can be found over at BH Photo Video.  If I’m looking to have 2 Camcorders, I can simply purchase a second capture card since I have several PCIe card slots in my video mixing computer.

Both the Camcorder and the Capture Card(s) will provide us with remote recording capabilities.  This won’t make us LIVE on remote, however it is a good start in that direction.  Another benefit gained by these two devices is the ability to have 3 in-studio video sources.  Now we can have a nice widescreen zoom able video feed from our studio couch when we have guests.

Next we’ll look at the options I chose for capturing audio from my host and his in-studio guests.  Be sure to join us for part 3.

How to Produce a Webcast… part 1

imageI’ve gotten back into the video game.  Years ago I had a web show called RootSync which I produced on a shoestring budget.  It worked well and had nearly 24 episodes (full season in TV terms).  Since then several things happened, I got a “real job”, divorced my Ex, closed my business, found a wonderful new wife, upgraded my job, upgraded my house, now I’m upgrading my broadcasting capabilities.Avatar

My latest venture into webcasting is a News Review called Week In Review.  I’ve worked hard on this show technically and have added so many new technically interesting features to make it happen.  Below is a short list of technical things that need to be learned and sorted out:

  1. Our Host and general theme of the show.
  2. Microsoft Cinema HD USB cameras for capturing high quality video.
  3. Wireless Label Microphones from RadioShack for capturing our hosts audio.
  4. Using a Xenyx1002B audio mixer to bring together both label microphones, Skype audio, and my computer’s audio then feeding them into VidBlaster for broadcasting.
  5. Utilizing VidBlaster for mixing multiple video sources together, broadcasting it over to uStream, and recording it for later post-production.
  6. uStream for the LIVE aspect of our show.  Broadcasting occurs every Friday at 7pm CST and uStream helps us broadcast LIVE.
  7. YouTube for the hosting of our episodes that have been post-produced.
  8. Using Windows Live Movie Maker for Post Production.
  9. iStockPhoto for royalty free videos, pictures and images.
  10. WordPress for hosting the main website which ties it all together.
  11. Publicizing our show by utilizing social networking like Twitter, Facebook, IMAutomator, etc…

I will be going into depth on each of the above technical aspects of the show and hopefully by the end of my Webcasting series you’ll have the knowledge needed to produce your own Webcast.

Our Host

A very important part of any new Webcast web show is your host.  The host must be interesting, insightful, and knowledgeable on the topics to be covered.  It helps if your host has the time to research and find the stories or topics that they would like to talk about in a way that would interest an audience.

David Smith3For my latest Webcast, my friend David will be hosting the show while I get to focus on the technical stuff.  David is a long time friend and has tons to talk about.  He has an actual PHD, he has lived and worked in L.A. during the riots, San Francisco, Las Vegas, Rome, and has ended up in Northwest Arkansas.  His extensive knowledge about a wide array of subjects makes him a very interesting listen and I believe the world would be better with his views shared.

David and I have been meeting every Friday for dinner ever since I can remember.  During our Friday dinners we’d talk about how our weeks have gone and what has happened in the world during the week as well as how those events would effect our lives here in Northwest Arkansas.  A few months ago we decided to record our discussions and share them with everyone and a new show was born.

Now that we have our host and the general theme of the show, it’s time to focus in on the technical aspects.  In part 2, I’ll discuss the video hardware used during our show.
