Make sure you have Windows Media 9 Runtime installed on the cluster machine used for the WM encoding. To use the Windows Media Encoder for ingest, choose the corresponding option from the list of WEB supported encoders for your ingestor:
Press the setup button of the Windows Media plug-in in the ingest window:
The following dialog box appears:
Making Your Windows Media Encoder Remote
In order to place the encoding on a remote machine, do the following:
Select the "Remote mode" option.
Set up the ID of the remote machine where you want to run the encoder.
Setting Up the Number of Encoded Streams
Windows Media can encode several qualities inside one stream. Nevertheless, there are certain limitations on different streams. If you need the streams of the bit rate and the frame size in a bigger range, you can enable up to three parallel Windows Media Encoders with independent settings.
|Of course, you can combine both approaches. For example, you can have three streams inside every one of the three encoders, thus achieving nine parallel output video streams.|
Select the "Deinterlace" option in order to enable deinterlacing for encoding stream.
To enable writing the timecodes to the stream, select the corresponding option.
To add the timecode in the form of a running clock superimposed over the encoding footage, select the "Superimpose timecodes to the frames" option.
In order to set up the Windows Media plug-in:
Press the button with the name of the stream you want to set up. The following dialog box appears:
Select the desired profile from the drop-down list. Press "OK".
Repeat steps 1 and 2 for all the profiles.
The TV format represents the format chosen in the ingestor plug-in.
|To check the settings of the Windows Media profile, press the "View content…" button.|
Performance of Windows Media Encoder
The performance of the Windows Media Encoder may vary greatly depending on the task. The larger the frame rate, the size, and the target bit rate, the bigger the load.
For example, compressing 4 - 5 streams will require a dedicated Dual Xeon machine. On the other hand, one Internet-quality stream is a very light task and can be squeezed into one of the cluster machines along with the other tasks.
Creating and Modifying Your Own Windows Media Profiles
Make sure you have Microsoft Windows Media Encoder installed. This application will allow you to create and modify the profiles.
|Refer to the TV Formats, Profiles article of the Cinegy Enterprise Manager Manual for information on how to create Windows Media profiles or ask your system administrator.|
|Refer to the Microsoft Windows Media Encoder help files to learn more about working with the profiles.|
The WM Encoder gets the incoming video "as is"; so if you are going to ingest interlaced material, the corresponding WM profiles must contain deinterlacing hint.
If you are going to encode high bit rate WM streams with fields (WM9 required), you have to set the corresponding feature in the profile. In this case, you should use the original frame size.
|Material ingested without audio on channel 1 or with no audio at all must use a separate WM profile that has its audio disabled as some Windows Media players are unable to play when there is no audio in channel 1.|
