Introduction and Product Philosophy:

Some video software products have a limited range of configuration options and have quite

rigid hardware requirements often based on what was available at the time the product was

being designed. VidBlaster is different, offering a truly modular design which creates a vast

number of permutations in the way it can be configured, allows connection to a wide variety of

input and output hardware, and processes a range of frame rates and image sizes from SD up to

full HD at 1080p. The result of this forward-thinking approach is that the VidBlaster software is

continually pushing past the boundaries of what is theoretically possible using todays PC

hardware.

Your Edition:

There are 4 public editions of VidBlaster: Home, Pro, Studio, and Broadcast. There is a level for

every type of user. The primary limitation of the 4 editions is the number of usable modules:

Home: 7 Modules, Pro: 15 Modules, Studio: 25 Modules, Broadcast: 50 Modules

There are 2 special editions of VidBlaster:Wall Street Edition: The Wall Street Edition only works with the Wall Street Project Portal,

and has 25 Modules.

Student Edition: The Student Edition only works with the Harvard Project Portal, and has 15

Modules

Select your Camera source:

With your camera, connected via USB, direct SDI input, HDMI, or built-in Webcam, The Camera

1 Module allows you to select a camera source, as shown in this screen capture:

IP Cameras can be brought in as live camera sources, by selecting IP Camera, from the pull-

down, and then right click on the camera module, and enter the IP address of the camera,

and if needed, the user name and password credentials, of the camera.


4/45

Set-up Camera options:

There are many camera options that can be changed in order to accommodate specific video

input types, resolutions, frame rates, signal quality improvements such as Deinterlacing,

Cropping, and Aspect Ratio.

Many camera types are compatible with VidBlaster including IP cameras, Broadcast Cameras,

and consumer webcams. The Camera Module can also be used as a Screen Capture for live

Skype or ooVoo video capture. SEEBRINGING SKYPE INTO THE PICTURE

The Frame Rate of the camera can be left in the Auto: option, unless a specific frame rate is

needed for the camera video to work. Usually, this frame rate will match the Video Frame Rate

selected for theVideo Output setting.

For HD Cameras, that are interlaced, such as 1080i format, select the Deinterlace option, as this

will eliminate the motion artifacts associated with interlacing.

The Transition feature, allow the user to select preset cut or dissolve modes when clicking on

the module to switch the camera into the live stream.

One of the great features of VidBlaster, is the ability to Crop the camera video, this is especially

helpful in the set-up of Skype and other conference video inputs that are inherently 4 X 3

aspect ratio, and need to be mixed into an HD program stream.


5/45

Below, is an example of how to use the Crop feature. The video source from this camera does

not fill the entire picture frame:

Here, we will crop the picture left area by typing in a number. In this case I will use the number

30, as there is only a small border on the left and right Click OK and the picture will expand left:


6/45

Repeat the same for the right side, and now the camera video will completely fill the frame:

You have now corrected the video with the Crop feature:


7/45

You can add additional cameras by Clicking MODULES >> ADD >> CAMERA I or CAMERA II

Modules.

The major difference between Camera I and Camera II modules, is that a Camera II module can

be resized. Right Click on the Camera Module, and select the Display Size option. Then Select

25%, 50%, or 100% to change the module size from the default size to larger size:


8/45

Set the Video Output Resolution and Frame Rate:

You camera source will determine which Video Resolution and Video Frame Rate is best for

your video stream. There are several resolutions to choose from.

For HD operation there are two basic resolutions: 720 and 1080When using an HD Webcam, HD-SDI input, or HDMI input, select the resolution that matches

the camera source.

The Video Frame rate usually depends on what region of the world you are operating from.

U.S. typical frame rates are 30 FPS or 29.97 FPS, and European Frame Rate is 25 FPS. Usually

one of these resolutions will suffice for most areas of the world, If not certain, refer to the

video frame rate generated by the camera source.


9/45

Select your Audio Source:

Audio can come from your plug-in microphone or webcam, an external audio mixer, or from the

internal microphone in your laptop. Pull down and select the audio source from the Audio

Module, as shown:

For more details about audio control, seeAudio Module Setup

Select your Streaming Publishing Point:

Here is where you point your stream for a live webcast. If you have an account with a service

provider, such as LiveStream, UStream, Justin TV, or Bambuser, you can enter your channel

name, user name, and password.


10/45

If you have a private CDN such as Communitek.TV, select Stream to FMS,

Enter the provided server URL:


11/45

Enter the desired Stream Name, along with any authorizations codes:

Set the Steam Resolution and Quality

This setting depends on what outgoing resolution you desire for your webcast.

Check with your CDN to obtain the optimal resolution for your channel.

Its important to know what your incoming video resolution and aspect ratio is, before selecting

the outgoing resolution. If your incoming video is HD, an inherently 16 x 9 aspect ratio, you can

scale the output resolution to a 16 x 9 size that is compatible or designated by your CDN, all theway up to full HD resolution.

Typical resolution for free streaming service is 640 x 360, and the bit rate is generally

500KB/Sec. If you keep in mind that high quality audio requires some bandwidth, you are

looking at 628KB/Sec total (500 KB/Sec + 128 KB/Sec).

For HD projects, such as the Wall Street or Harvard projects, the stream quality will be about

1.2 MB//Sec, at either 720P or 1080i resolutions. Make sure you have the bandwidth available

from your ISP to accommodate the 1M+ bandwidth requirement. If the bandwidth is not high

enough, you may consider streaming at lower bit rates.


12/45

On the Streamer 1 Module, right-click and select Stream Resolution >> Select the desired

resolution:

The main purpose of this setting is to determine the outgoing picture size for the live stream.

This setting is may also be determined by your CDN or hosting service. Check your provider.

Stream Quality is the actual bit-rate that you will be sending out over the internet.

This setting depends on two factors:

1- The bit-rate established by the CDN for your channel

2- Your on-site available outgoing bandwidth


13/45

Select the desired Stream Quality:


14/45

One Click and Go Live!

If you have a Wall Street edition or Student Edition, your publishing point will already be pre-

programmed and ready to stream.

Otherwise, if you have setup your Streamer1 credentials, you are ready to Go Live

with one click of the Start button.

Your stream will point to the designated publishing point, and be distributed by the chosen

CDN. Remember that once you click Start, you are live to the web!

To add graphics such as bmp, jpg, gif, png to your webcast,

Select the Player 2 Module, and OPEN >>>BROWSE>>>(Select Directory),

and click on the file that you want to broadcast.

After selection, any graphics file or video file in the chosen directory can be easily selected from

the Player Module Pull-down list.


16/45

Adding Titles and Lower Thirds to your Webcast

Adding titles is as easy as typing the words, and clicking on the Overlay Module. To see an

example of this feature, left click on the Overlay Module, and you will see the VidBlaster Logo

keyed into the Program Module.

Now select the pull-down on the Overlay Module and you will find several pre-made files.

Select any of the graphics from the list, and you will see how easily the graphic can be changed.


17/45

Now put your cursor in the field under the graphic file name, and type any character, you will

see the characters that you are typing, appear as a title in the lower third with the graphic.

Right click on the Overlay Module, and select FONT. Then, select a Font size of 36 or larger and

you will clearly see the characters in the Overlay Module. You can add attributes such as bold,

outline, italics, and change the font type and color.

Once you have determined the attributes, you can simply click on the Overlay Module, and the

graphics text will appear keyed into the Program Monitor.


18/45

PowerPoint Presentations:

It is very easy to mix in direct PowerPoint presentations to your live webcast.

Simply add a PowerPoint Module: Click MODULES >> ADD >>POWERPOINT

The PowerPoint1 Module will open. Next Right Click on the PowerPoint Module to Open a

folder:


19/45

Next, select the folder and the file for the PowerPoint you would like to include in the Webcast:

Click Open and the selected PowerPoint will appear in the PowerPoint Module:

When you click on the PowerPoint Module, the PowerPoint will show as the live Video Source.

You can advance the slides by clicking the Next Button, or go backwards with the Prev Button.


20/45

Alternatively you can right click on the module and select the Auto Slide Advance option, and

pick a time interval for the auto advance:

Note: In order for PowerPoint to work in VidBlaster, you must also have Microsoft Office or

specifically, Microsoft PowerPoint installed on your PC. You can have multiple PowerPointModules, loaded and ready to stream, and you can easily change PowerPoint presentations

with the PowerPoint Module pull-down tab.

Again, when you click on the PowerPoint Module, the full slide will appear in the Webcast

Note that PowerPoint is inherently based in 4 x 3 aspect ratio. When you stream HD at 16 x 9

aspect, the PowerPoint will appear centered in the video frame with pillars on the sides. By

utilizing theVideo Effects Module, you can enhance the way PowerPoint presentations look on

the live webcast.


21/45

Here is an example of an enhanced PowerPoint using the 3D Vertical Split in theVideo Effects

Module.

Additional effects that can be used with PowerPoint include Picture-In-Picture(PIP), Horizontal

Splits, and Vertical Splits. The live camera video can be placed in the same frame as the

PowerPoint and a background can be added for very professional looking webcast.


22/45

Audio Module Setup:

The Audio Module allows VidBlaster to take audio from any available computer audio source or

an audio capture card.

You can then control the audio level with the Volume Slider control, and you can monitor the

audio bar-graphs of the Left and Right audio channels:

Audio levels between -12 and -6 db will give the best audio results without distortion.

If you have an audio mixer plugged into your computer audio, you can set this control once for

a reference level, and adjust the audio level externally with the mixer.

Some audio sources, such as the microphone from a webcam, may have automatic audio gain

or level control. This is fine, and will generally maintain consistent audio level to VidBlaster.


23/45

The audio source is also controllable within the Windows operating system, under CONTROL

PANEL >> HARDWARE AND SOUND >> SOUND. Click the RECORDING TAB, and Select the Audio

Source.

From there you can also adjust internal computer audio levels, if needed, by clicking

PROPERTIES >> LEVELS:


24/45

Bringing Skype into the Picture:

It is very easy to have a Skype caller become part of your live webcast. Skype callers can be

captured live as a camera source.

Simply add a new Camera Module:

The result will be a new camera module with no designated input. Click on the Camera select

tab, and select Screen Capture. You can label the module SKYPE CAM:


25/45

Now open Skype, and connect to someone you want to bring into your live webcast.

Make sure that person your connecting to have enabled their video camera in Skype.

After establishing the connection, go back to the VidBlaster program, and you will see the videofrom the caller on the right hand upper area of the VidBlaster screen.

Note: make sure to leave some empty space on the screen, and if needed move modules out of

the area where the Skype video comes up:


26/45

Next, right click on the Camera 2 module and select CAPTURE >> SELECT AREA 4:3:

Then put the cursor at the top left part of the Skype video, and while holding the mouse button,

drag down the cursor, and you will see the outline of the capture. Follow the contour of the

Skype video until you get to the bottom, then release.


27/45

You will now see the Skype video caller in the Camera 2 module:

Click on the Camera 2 Module, and the Skype caller will appear directly in the live Webcast.

This is a good time to check out theVideo Effects Module, to create a PIP or Side-by-Side video

effect, which will show both the local users camera and the Skype participant in one stream.

Add titling, graphics, and a background, to create a network TV like experience for your webcast


28/45

A word about audio for Skype: The Skype audio from the caller, will be routed to the

computers audio output. Best practice for mixing Skype audio with local audio is to connect the

audio output of the computer to an audio mixer. It does not have to be an expensive mixer, but

one that will take the audio from the computer and mix in the local audio from a microphone or

other audio device. The output of the mixer can then be re-inserted into the computers audioinput or audio capture card. This will enable control of the Skype audio level and the local

microphone level for a good broadcast-streaming experience.


29/45

Add Effects to your live Webcast:

To have two or more cameras appear together in the live webcast, use the Effects Module.

To add the effects module, click the MODULES tab >> ADD >> VIDEO EFFECT:

The Video Effects Module will appear:

Note that there are three Pull-down tabs.


30/45

The long pull-down tab, in the middle of the Video Effect Module, is the Effects Type, which

includes Picture-In Picture, Horizontal and Vertical Splits, Chroma Key, Side-by-Side, Triple and

Quad Splits, and a 3D Split.

Select on one of the effects, such as PIP (Picture-In-Picture).

Then select a source for the full screen (left tab), and a source for the inserted Picture (right

tab):


31/45

Clicking on the Effects Module, will bring the PIP Effect into the live webcast.

You can change the type of effect in real-time, live while webcasting, or in true broadcast

fashion. Select a full camera shot, change the effect, and then click on the effect module to

show the new effect.

You can reposition the inserted picture anywhere in the video effects module, and resize the

inserted picture to any aspect, width, or height desired.

For Skype callers, a typical video effect is the Side-by-Side effect, which will make the Skype

caller appear much like you find in a professional network newscast:


32/45

The Video Switcher:

You can produce TV Broadcast shows and presentations, with VidBlaster, by utilizing the Video

Switcher Module. In professional studio operations, broadcasters have two main screens, a

Program Monitor, and a Preview Monitor. They also have multiple smaller monitors which are

used to see live views of all the camera and graphics sources. They then use a switcher to selectwhich scene, effects titles, graphics or pre-recorded video goes to air. VidBlaster provides all of

this functionality on screen with a Program Monitor, Preview Monitor, Switcher, and all video

sources, in a Multi-viewer configuration:


33/45

To start the Video Switcher, go to MODULES on the toolbar and click >>ADD >> PREVIEW

The Preview Module will open:


34/45

Next, right click on the Preview Module, and select the desired Monitor Display Size:

The size of the Program and Preview Display is entirely up to you, and based on you actualavailable computer screen size, and the chosen video resolution. Notice also that display size

ratios are available as 16 x 9 or 4 x 3. 640 x 360 for example is 16 x 9, whereas 640 x 480 is 4 x 3.

You can now place the Preview Module anywhere on the screen that you desire:

A typical configuration is to have the Program and Preview Monitor next to each other towards

the top of the computer screen.


35/45

Next, click MODULES on the tool bar and ADD >> VIDEO SWTICHER:

The Video Switcher will then appear, and can be moved to any desired area of the computer

screen:

When you click any source on the top row of the Video Switcher, the selected input will go

directly to the live stream. When you click a source on the bottom row, that source will appear

in the Preview Monitor, and will be ready to take as either a straight hard cut or a dissolve.


36/45

Here we have selected Camera 1 on Program and Player 2 on Preview:

To change the transition type to a dissolve, click the Transition pull-down tab and selectDissolve:


37/45

Then set the Dissolve Duration (time in milliseconds, i.e. 1000 = 1 second):

When you click Trans button on the Switcher Module, the transition will be performed.

Whatever source was on the Preview Module will fade in, and appear in the Program Monitor

as the live stream picture, and the former Program source will fade out, and appear in the

Preview Monitor:

As you add more Modules to your VidBlaster application, the switcher will increase in size

horizontally, to accommodate more switcher buttons. The switcher also has a Cut button,

which will do a quick switch between Program and Preview sources.


38/45

If there is no one available to switch cameras, in a live webcast, the Auto switching option can

be selected, with a preset interval defined in seconds:

Then simply click the small box under each camera that you desire to auto switch and

VidBlaster will automatically switch the live cameras, or any other source that you have

selected:

To exit the Auto mode, click the pull-down to the right of the seconds interval, and select

off, the switcher will return to normal manual operation:

the switcher will return to normal manual operation:


39/45

Video Roll-ins (Player Module):

Pre-recorded videos can be rolled-in to your live webcast with the Player Module.

The Player Module will accommodate every type of video file, including MOV, AVI,

WMV, MP4, and MPEG2.

In the default start-up of VidBlaster, Player 1 and Player 2 Modules are included already.You can use one of the two or add additional Player Modules. Working with the Player 1

Module, right click on the module, and select Open:


40/45

Then, navigate to the folder where your videos are stored, and select the desired video file:

The selected video will appear in the player, and can be switched and played into the live

webcast.

Select Player 1 on the Program row of the Switcher and click the Play button on the Player 1Module:


41/45

The video will play in the Program Monitor:


42/45

Add Titles and/or lower thirds graphics and logos, by clicking on the Overlay Module as

described previously:


43/45

The Record Module

The Record Module allows the user to record or archive their live stream as a video file.

Click MODULES >> ADD >> RECORDER

The Recorder can be started or stopped anytime, and does not require that the live stream bestarted.

Naturally you can live stream and record at the same time, or separately, as needed.

Simply click the Record Button when you want to record the Program video:

The red light come on, at the upper left of the module, and the time counter will increase.

the number to the right of the time counter, as in /24:09:14, shown above, is the number of

hours minutes and seconds of available recording time. This is based on your available free hard

drive space.


44/45

When done recording, click Stop. Then, to archive the recording, Click Save. You now have the

option to archive as WMV, MOV, MP4, or FLV.

Click Save again, and your file will be archived in the format you choose.

There are some options for the Record Module. As most users are looking to upload to their

videos to the web, the default recording mode is compressed. However, you can change the

recording mode to Uncompressed. Another option is the ability to change the directory for the

temporary video storage during recording:


45/45

After your recorded file has been rendered, you can immediately upload your file to your

Video-On-Demand service provider, or one of the free services, such as YouTube.

You can also bring the recorded video files into a Video Player Module, to replay the pre-

recorded video into a live webcast.

MPEG Recorder:

There is secondary Recorder Module, in VidBlaster called the MPEG Recorder Module.

This module functions much the same way as the original Recorded Module, with the added

feature that it will record the file as an MPEG-2. This module can also record DVD codec-

MPEG2, which renders the file ready for DVD authoring.

Another feature of the MPEG Recorder Module, is that it can record any input source, thus it is

not limited to the Program video stream. This is known in the TV industry as ISO or isolated

recording. The Audio input can also be isolated, or the same program audio that the Audio

Module as been configured for.
