LIVE WEBCAST WITH WIRECAST v4.1 LIVE ENCODER
Breakdown of costs.
Webcasting is free for the viewers,
but if you are wishing to be the broadcaster of a live webcast, you will need to take into consideration the following:
Wirecast Live Encoder
- Powerful flash-based H.264 encoder | download now.
- Free trial download available for testing.
- $450 program makes this expensive but it's powerful.
- AAC is already built-in so your webcasts would be available on mobile devices such as iPhone, iPad, Android, BlackBerry, ROKU TV.
- Allows for graphics overlay on the webcast.
- Supports multiple cameras and smooth transitions.
- A bit more complicated to setup.
- You must be a "FULL" Broadcasting Member (more info).
- You must have the "Live Webcasting" option enabled for your account (some fees apply):
- Only $10 is added to your base monthly fee.
- Only $2 per webcast hour (additional usage fee).
Our pricing is straightforward and does not scale up or down depending on the number of viewers. We've taken the mystery out of
complicated webcasting costs, so you can easily predict your costs from month to month. Just remember, flat fee + usage fee!
- You must have a direct, high-speed connection to the Internet with a sufficiently fast upload speed.
- At least 350kbps upload recommended bandwidth for video webcasts.
- At least 1Mbps upload recommended bandwidth for HIFI video webcasts.
Multiple bitrate support. The higher bandwidth recommendation assumes that multiple bitrates will be streamed for any given webcast.
This allows for maximum viewership.
- For video webcasters, a fast, separate, dedicated computer used for only the webcast encoding with a "decent" graphics card is highly recommended.
- Quick Setup Tips. Here are some quick tips and links to get you started.
- Recommended! Single camera with firewire output -- use the built-in firewire OUT on the camera to the computer. This is by far the easiest way if your camera supports firewire.
- Recommended! Single camera method -- use the Canopus ADVC300 to convert your analog audio/video signal from the camera to a single digital FIREWIRE signal -- to your computer.
- Single camera with HDMI output only -- use the Intensity Products to capture HDMI. This requires a much stronger computer to handle the uncompressed HD video. Not recommended for webcasting. But it is an option.
- Recommended! Multi-camera setup -- use a video mixer (like the Datavideo 4-Channel) to switch between your analog cameras. Take the single analog OUTPUT from the mixer into the Canopus ADVC300 to create a single digital FIREWIRE signal -- to your computer. This method does not require expensive cameras.
After you have met the above requirements, the following screen shots will take you step-by-step through the
process of webcasting a live event on SermonAudio with the Wirecast Live Encoder!
Step 1: Make sure your account is Webcast-Enabled.
There's a quick and easy way to see if your account is webcast-enabled. Go to the Live Webcasts section to see if your church is listed as a webcaster.
Or, look for the webcast badge on your homepage as shown.
Your account must specifically be activated for the FLASH webcasting solution. This will be indicated by a bright red webcast icon.
Step 2: Start Wirecast Live Encoder.
Next, you will need to start the Wirecast Live Encoder program on your computer.
This is a free (trial) tool from Telestream that you can download here!
This program already has AAC built-in so your webcasts will be
available on devices such as iPhone, iPad, Android, BlackBerry, ROKU TV.
Step 3: Next, set the BROADCAST SETTINGS options.
From the menu, select Broadcast / Broadcast Settings (CTRL+Y) and you will be presented with
a popup window where you can setup your various encoding streams.
This will allow you to initiate the live webcast to SermonAudio whenever you want and as often as you want.
The site will automatically detect your webcast and appropriate activate the right buttons on-site! A truly complete and flexible solution!
Examine the screen below, note the multiple streams..
Step 4: Next, set the ENCODING settings for each stream.
Click on the EDIT button for each of the streams to set the encoding parameters for that particular stream.
Try to copy the settings as you see them in the following screenshots for optimum user experience.
HIFI OPTION. Broadcasters that have the HIFI option enabled for their account can webcast at higher bitrates and upload archived media at higher bitrates. You must have this option enabled for your account in order to use the HIFI bitrates. To learn more, please click here..
Recommended encoding settings. Observe the following screenshots and
feel free to use these exact settings for your webcast needs. You can tweak the bitrate, video size depending on your situation:
See below in the Video Tips for more recommended video sizes..
Please abide by the limits and rules as outlined in the above points.
If you go over these limits, visitors may not be able to experience your webcast properly, your webcast may interfere
with other webcasts in progress, and we may therefore be forced to terminate the stream until it is corrected.
Step 5: Next, set the DESTINATION and OUTPUT settings for each stream.
As shown below, use your SermonAudio Member ID in the ADDRESS field for the publishing point. For example,
if your SermonAudio Member ID is "faith", then the full ADDRESS value would be:
Also observe that the STREAM field can be any value as long as it is a different name from the other streams.
This will give you the option of sending multiple streams (multiple bitrates) to our server.
stream1, stream2, stream3
Next, be sure to click on the SET CREDENTIALS button (for each stream) to specify your SermonAudio Member ID and Password.
This must be done for each stream.
Step 6: Specify credentials for each stream.
Clicking on the Set Credentials button will prompt you with a login window where you will fill in your SermonAudio
Member ID and Password. This password-protection is to guard against anyone
else webcasting under your account.
Step 7: START (CTRL+B) the webcast you're ON-THE-AIR!
That's it! Select Broadcast / Network Broadcast / Start All (CTRL+B) and your webcast will be LIVE and visible on SermonAudio.com!
Please note that usage charges are accumulated at this point, even for test runs.
Keep an eye on your current usage charges in the BILLING section of the Members Only Area.
Please note: Sometimes one or more of the streams may fail to start. You will need keep retrying to start
the stream in the Broadcast menu until all of them are started successfully.
Step 8: START (CTRL+K) recording the webcast to the FILE!
Optionally, you can select Broadcast / Record To Disk / Start All (CTRL+K) and your webcast will also record to the specified MP4/F4V FILE
which you can upload later as an archived video.
This is an action that is separately started and stopped from the actual webcast (CTRL+B) action.
VIDEO TIP 1: Recommended Encoding Settings.
Video encoding can get confusing. But the following details may help give some guidance
on what settings to use when encoding your video.
Please note: You are welcome to adjust these settings to suit your particular needs but please keep the following
issues in mind if you wish to change the settings:
- For standard video settings.
|Video Size:||360x270 (Widescreen: 480x270)|
|Video Profile:||Baseline 3.1|
|Audio Format:||AAC 24kbps-48kbps, MONO|
- For HIFI video settings.
|Video Size:||768x576 (Widescreen: 1280x720, 1024x576)|
|Video Profile:||Baseline 3.1|
|Audio Format:||AAC 24kbps-48kbps, MONO|
These guidelines provide the optimum encoder settings for the
best possible video and audio experience while at the same time ensuring that
our many dialup users can also enjoy your webcasts reliably.
- Viewers on PCs. Most of your webcast viewers will probably be on a PC of some kind. Fortunately, the flash-based streaming method allows for a no-hassle playback.
However, because connection speeds vary, we highly recommend using multiple bitrate streams.
- Mobile Phones. Most cell phones today can play videos and we take that into consideration with our iPhones, BlackBerry and Android solutions.
Providing a satisfactory streaming experience for viewers over a slower cellular network is part of our bitrate policy.
- ROKU TV. The same webcast viewed on PCs, Macs, and mobile phones, can also be viewed on the ROKU Internet Media device which connects to your television.
The recommended webcast encoding settings have been successfully tested on this platform.
- Dialup Users. There are still many who use dialup
and for them, it's important to deliver a lower-bitrate stream. For this
reason we recommend using our suggested encoding settings for the most reliable streaming experience.
VIDEO TIP 2: Quality Issues
New! If you are experiencing quality issues, we recommend that you try to turn OFF the "GPU Compression" option found
in the File / Preferences menu option. You can see a screen shot below:
VIDEO TIP 3: Quality Issues
New! Here's another tip. Be sure that the Capture Device Size is set to NATIVE in the Sources / Show Source Settings
menu option. You can see a screen shot below:
VIDEO TIP 4: Improving the Quality of "Noisy Video"
This entire step is an optional tip to help improve the quality of "noisy video" for those
experiencing this problem. The "noise" is a result of the interlacing artifacts that sometimes appears in video. The solution
is simply to turn ON the DE-INTERLACING option on your encoder settings if available.
Please note, this option is significantly CPU-intensive and is only advisable if your computer is fairly
new with a higher-end graphics card (that supports hardware de-interlacing).
That's it! Congratulations!
The site is designed to automatically detect when you are "ON-THE-AIR" and will
make it clear to all who are on the site that a LIVE webcast is in progress.
When you are live webcasting, the button will automatically change from the OFF AIR button to the ON AIR button.
Please note it may take up to one minute for SermonAudio to actually detect that you are on-the-air.
This simply means that the OFF AIR button may not change into the ON AIR for up to one minute.
You can keep the live webcast on-the-air for as long or as short as you wish. SermonAudio will automatically keep track of the number
of hours that are used in your live webcasts throughout the month and then add the total hourly usage charges for the month
to your next billing cycle.
In order to STOP the live webcast, simply press the "STOP" button or close
the program. Please be aware that it may be up to 5 minutes before SermonAudio is able to detect that you
are completely off-the-air. Do not be alarmed at this. We have taken these delays into account when calculating the usage charge for billing.
Here are some last-minute important tips to keep in mind!
Welcome to Live Webcasting on SermonAudio.. and enjoy!
- It is very important that you follow Step #4 (above) precisely
in regards to the bitrate setting. This needs to be correct or we will need
to terminate the webcast while in progress.
- Be sure that you do not "tie-up" the bandwidth at your location by trying
to watch the webcast over the same connection that the live webcast is
currently broadcasting on.
For video-webcasting, do not "disturb" the PC that is doing the video webcast.. not even so
much as clicking on the web browser. In fact, it is best simply to
completely leave it alone while the webcast is in progress. Video encoding
is a CPU-intensive process which can result in the webcast failing if it
doesn't have the computer's 100% attention.
