Chapter 5, Using Matrox VS4 with Telestream Wirecast
for your VS4 shot. Telestream Wirecast outputs one stereo pair when
streaming.
$ De-interlace Video If your source video is interlaced (i) and you want
to de-interlace your video before encoding, select
De-interlace Video.
This option is used to better display your encoded video on a monitor that
displays lines progressively, such as an LCD or computer monitor.
6 Click Save Settings to save the source settings for the selected VS4 input.
The saved source settings are automatically loaded when Wirecast opens,
and when creating a new Wirecast document.
7 If you want to configure another input for streaming, repeat steps 5 and 6 for
each input.
8 Set any additional encoding options in Telestream Wirecast as you would
normally, and then output your video.
¦NoteTo scale the source video for streaming to another video format, use
the scaling options that are available in Telestream Wirecast.
9 If you want to simultaneously record your original feeds to disk, see
“Recording your source video to disk” on page 66.
Recording your source video to disk
Matrox VS4 not only sends your video feeds to Wirecast for streaming (see
“Using Matrox VS4 for streaming” on page 64), it can also simultaneously
record your original video feeds to disk using the Matrox ISO recording tool. You
can, however, record your feeds without streaming.
¦NoteUp to two VS4 cards are supported per system. In a two-card system,
ISO recording is supported on the four inputs of the primary VS4.
You can record your input sources to disk using the available Matrox codecs. You
can use the Matrox MPEG-2 I-frame codec to create .avi files, and a Matrox DV
codec, such as DVCPRO or DVCPRO HD, to create .mov files. You can also
choose to record up to eight audio channels from any input source as separate
mono or stereo .wav or .aac files. A log file (Record.Log) is generated after every
recording session, wherein you can view the events for each input recording (see
“Record log file” on page 77).
¦NoteAll settings in the Matrox ISO Recording tool are automatically saved.
1 Connect your video source(s) to the VS4 SDI input(s) (see “Connecting
devices to Matrox VS4” on page 11).
¡ Important If connecting sources with different video formats, the sources
must have compatible frame rates. For a list of compatible frame rates, see
“Supported input formats” on page 10.
