Chapter 5, Using Matrox VS4 with Telestream Wirecast
Filename
In the
Filename box for each VS4 input, specify the base name for your recorded
files. A default base name is provided, but you can change this name if you want.
The base name applies to both the video and audio files that are recorded, but the
naming conventions for video and audio files differ (see “Matrox VS4 file
naming conventions” on page 73”).
Video file type selection
Under
Video File Type for each VS4 input, select one of the following:
•
Matrox AVI Creates an MPEG-2 I-frame .avi file with embedded stereo
PCM (WAV) audio.
¦NoteMatrox MPEG-2 I-frame (.avi) files are not supported in Avid editing
applications on Windows systems.
•
Matrox MOV Creates an .mov file in a selected DV format, such as
DVCPRO or DVCPRO HD, with embedded stereo or mono PCM (WAV)
audio. This option is not available for 1080p @ 24 fps source video.
Audio is embedded in the file only if you choose to record audio with your video
(see “Audio settings” on page 71).
Codec settings
Under
Codec Settings, specify the settings that you want for each VS4 input as
follows:
¦NoteWhen selecting a video codec, make sure that the codec is supported in
your editing application. Working with Matrox MPEG-2 I-frame .avi files
requires a system with the appropriate Matrox codec installed. For details, see
“Working with editing applications” on page 77.
•If the
Video File Type is set to Matrox AVI, use the provided slider to select
the data rate (in Mb/sec) at which the Matrox MPEG-2 I-frame codec will
record your source video to disk. The last setting for an SD or HD source is
automatically saved and loaded when an SD or HD source is connected to
the input. Click to set the data rate to the default value for an SD or HD
input source.
•If the
Video File Type is set to Matrox MOV and your source video is HD,
the codec will be set to
Matrox DVCPRO HD. For SD source video, you can
select one of the following codecs for recording your video:
$ Matrox DV/DVCAM Records video to DV or DVCAM format.
$ Matrox DVCPRO Records video to DVCPRO format.
$ Matrox DVCPRO50 Records video to DVCPRO50 format.
