Matrox VS4 - Record Log File; Working with Editing Applications

77
Working with editing applications
Matrox VS4 displays the following input states:
• Valid input signal If a valid signal is connected to an input, such as 1080i
at 29.97 fps, the video format is displayed under the input label. If the input
is selected for recording, the resulting video file will be in the displayed
video format.
• No input signal/Invalid input signal If VS4 detects no input signal or an
invalid input signal for an input,
Disconnected or Invalid Input Signal
will be displayed respectively. If the input is selected, the input indicator
switches between displaying the state (
Disconnected or Invalid Input
Signal
) and the last valid video format detected for that input. If you record
an input in this state, the resulting video file (black video) will be in the
displayed video format. For example, if the input indicator shows
Disconnected and NTSC, the recorded video file will be NTSC. If you
connect a valid source to an input in this state when recording the input,
make sure the source’s video format matches the displayed video format to
avoid creating a new file.
Record log file
After every recording session (see “Recording session” on page 74) a record log
file (Record.Log) is generated. The Record.Log file is located in the same folder
that contains the files for that recording session. When dropped, skipped, or black
frames occur during a recording session, the Record.Log file provides a
breakdown of events by input, and the timecode of when the events occurred.
Working with editing applications
You can use the recorded video and audio files in your favorite editing
application for post-event editing. However, working with Matrox MPEG-2
I-frame .avi files on a Windows system requires that the Matrox Video for
Windows (VFW) software codecs be installed. The VFW software codecs are
automatically installed along with your Matrox VS4 software. If you plan on
working with Matrox MPEG-2 I-frame .avi files on a Windows system without
Matrox VS4, MXO2, CompressHD, Mojito MAX, or Mojito 4K hardware, you
must download and install the Matrox VFW codecs on that system.
To work with Matrox MPEG-2 I-frame .avi files on a Mac OS system without
Matrox MXO2, CompressHD, or Mojito MAX hardware, you must download
and install the Matrox MPEG-2 I-frame codec on that system. To download the
Matrox VFW software codecs (Windows) or Matrox MPEG-2 I-frame codec
(Mac OS), visit the Support section of our website at
www.matrox.com/video/support.
When using the recorded video and audio files for multi-camera editing, realtime
performance is supported only for Matrox MPEG-2 I-frame .avi files in Adobe
