When in quad-view mode, this button switches VS4Recorder Pro to single-view mode with the corresponding source expanded to fill the entire VS4Recorder Pro source window area (see “Source view” on page 55).
23 1 Connect up to four sources to the SDI inputs on the VS4 card (see Chapter 3, “Connecting External Devices to Matrox VS4”). Make sure to always connect a source to Input 1. ¦ Note To ensure that each recording has the same starting timecode when starting the source recordings at the same time, the video inputs must be genlocked to the same reference signal (see “Timecode settings” on page 47). 2 Select a recording mode (see “Recording sessions” on page 25).
24 $ Independent mode Click the Record button in the source window popover (see “Source window popover” on page 20) for each source that you want to record. ¦ Note If dropped/skipped frames are detected during a source recording, the Record Status LED in the corresponding source window turns yellow, and a Dropped-Frame indicator appears (see “Record status” on page 26).
25 Record functionality This section describes the VS4Recorder Pro record functionality. Recording sessions VS4Recorder Pro offers two modes for recording and a multiple-VS4 networking workflow: Multi-Cam mode, Independent mode and VS4Control. To select a record mode, click the Record Mode button on the Control bar.
26 Recording sessions and timecodes VS4Recorder Pro includes timecode metadata (see “Viewing VS4Recorder Pro metadata in Adobe Premiere Pro” on page 60) in every recorded video file for easy synchronization in Adobe Premiere Pro CC and CS6. The starting timecode in a video file corresponds to the timecode at the moment when the source recording was started.
27 Green LED (on) Source is connected and enabled Red LED (pulsing) Source is recording without incident Blue LED (pulses briefly) An event marker has been created Yellow LED (pulsing) Recording currently experiencing dropped/skipped frames Remarks • The green LED indicates that a valid sources is connected; however, if a source is disabled during a Multi-cam session, the green LED will replace the pulsing red LED. • The red LED pulses when the source is recording.
28 Record Path button At the end of a recording session, a Record Path button appears either on the VS4Recorder Pro Control bar when in Multi-Cam mode (see “Control bar” on page 17), or in the recording’s source window when in Independent mode (see “Source window popover” on page 20). Click the Record Path button to open Windows Explorer at the specified source record path to view the recorded video and audio files, and the record log file.
29 • VS4Control One record log file is created per machine, and they are generated once the entire recording session is stopped. The record log files include the breakdown of events for all sources that were recorded from their respective machines during the recording session.
30 • Event markers are also good visual cues for verifying that files are in sync when editing. Event markers in a set of split video files on the timeline can help in the adjustment any offset files in the set.
31 Settings This section explains the VS4Recorder Pro settings.
32 Accessing the VS4Recorder Pro settings To open the VS4Recorder Pro Settings window, click the Settings button on the Control bar (see “Control bar” on page 17). Session and Machine names As captured video files are created and saved, a naming convention is applied to make them easy to locate and identify. For more information, see “File naming convention” on page 35. The Session Name is the name you enter for the recording/capture session.
33 Working with 1080i/PsF and SD sources Some PsF and SD 16:9 video signals do not include scan mode or aspect ratio information as part of the signal. To avoid possible errors in detection when the input source is 1080i/PsF at 25/29.97 fps, NTSC, or PAL, VS4Recorder Pro requires that you indicate whether or not the 1080 source is PsF, and whether or not the NTSC/PAL source has a 16:9 aspect ratio.
34 The folder name is in the following format: SessionName-YYYY-MM-DD HHMMSS If the Use same path option is cleared in the VS4Recorder Pro settings, a separate session folder is created for each of the source recordings in the source’s specified record path. The folders are differentiated by the source input number in the following format: SessionName-YYYY-MM-DD HHMMSS_input • Independent mode A separate session folder is created for each of the source recordings in the source’s specified record path.
35 File naming convention As captured video files are created and saved, a naming convention is applied to make them easy to locate and identify. The naming convention follows a specific order of identifiers; however, the saved video file path changes somewhat depending on your settings. For example, the Include in Filename drop-down menu options, the use of file splitting, or choosing to record in Stereo or Mono all have an effect.
36 File naming based on recording session As captured video files are created and saved, a naming convention is applied. Although the naming convention follows a specific order, the file naming convention differs based on the recording configuration: • Multi-Cam mode \sessionname_date_time\filename_sessionname_machinename _InputIndex _index.fileextension • Independent mode \date_time_input\filename_machinename.
37 Under Session and File, specify a descriptive label in the Label box for each source. Capture duration You can set a capture duration limit that stops a recording session after a specific time limit. Once the limit is reached, the recording session will stop automatically. How capture duration works A helpful feature of setting a capture duration is the option of unattended recording. The Capture duration feature operates in minute increments, and the minimum settable duration is one (1) minute.
38 • VS4Control: $ The time limit is set and controlled through the settings of the Master only (the slave settings are ignored). $ When you stop the Master, the recording stops and the timer resets. $ The Capture duration option will not be available for slave units (see “VS4Control” on page 51). Setting a capture duration Setting a capture duration means stopping your recording session at an exact time, which can be convenient when your sources are at a distance.
39 • Multi-Cam mode: $ One split timer is set for all inputs. $ When you stop the recording session, the split timer resets. $ When you connect an input while capturing, that input will split at the scheduled interval without resetting. $ When you disconnect and reconnect an input while capturing, that input will split at the scheduled interval without resetting. • Independent mode: $ The split timer operates independently for each of the inputs.
40 Split file naming An automatic naming convention is applied to split video files. An index will be appended to the split file (see “File naming convention” on page 35). However, if a file name is changed during a capture, the next split file will not get the new file name (as its base file name).
41 ¦ Note When selecting a video codec, make sure that the codec is supported in your editing application. Working with MPEG-2 I-frame .avi files requires a system with the appropriate Matrox codec installed. For details, see “Working with editing applications” on page 60. HD settings Under Video Codec, from the HD Settings menu, select the video codec that will be used for all subsequent HD recordings: • H.264 (MOV, MP4) Creates either an H.264 .mov or .
42 Creates an MPEG-2 I-frame .avi file with embedded stereo PCM audio. If this option is selected, specify the Data Rate (in Mb/s) at which the MPEG-2 I-frame codec will record your source video: $ You can set the data rate to any value between 10 Mb/s and 50 Mb/s. • MPEG-2 I-frame (AVI) $ Click to set the Data Rate to the default SD value. ¦ Note MPEG-2 I-frame .avi files are not supported in Avid editing applications on Windows systems. • DV/DVCAM (MOV) Creates a DV/DVCAM .
43 1 Confirm that your CPU supports QSV technology. 2 Enable your Intel graphics card to work with Intel integrated graphics (iGPU) in BIOS and save changes. 3 Install the latest Intel graphics drivers (strongly recommended). QSV acceleration may not be available or not work with old graphics drivers. 4 Go to your Screen Resolution settings, and click Detect to expose inactive video outputs.

If you select Variable bit rate (VBR), three other settable controls will be available: The GOP size, the target and maximum data rates for the video compression. Audio settings You can choose whether or not to record audio along with your video. The following sections detail the audio settings for recording.
46 File type Under Audio Codec, select the type of separate audio files that you want to create: • WAV Records PCM audio to separate .wav files. • AAC Records AAC audio to separate .aac files. WAV files The WAV audio format has a restriction; namely, .wav files have a maximum size of 4 GB. This means that depending on your audio settings, when you record separate .wav files along with your video, the .wav files are limited to a maximum duration. If you wish to capture a lengthy separate .
47 Bit depth Select the bit depth that you want for the two channels of embedded PCM audio in your video file, and the separate audio files that are recorded. Channel type Select the channel type that you want for all the separate audio files that are recorded. If recording to an .mov video file (see “Video codec” on page 40), this setting also applies to the audio that is embedded in the recorded video file. • Mono Creates a separate .wav or .aac audio file for every selected channel.
48 To set the embedded timecode option, under Timecode, select one of the following: • SDI Embedded The starting timecode value for the recorded video file is based on the timecode present in the SDI video signal. • Session The starting timecode can be set to a valid value. • System Time The timecode is taken from the local computer configuring the VS4Recorder Pro settings.
49 • Multi-Cam mode The starting timecode value is based on the session timer on the Control bar (see “Control bar” on page 17). • Independent mode The starting timecode value is based on the timer in the respective source window popovers (see “Source window popover” on page 20). • VS4Control The starting timecode value is based on the session timer on the Control bar of the Master.
50 This selection makes the time-of-day, as interpreted by the machine, the recording starting value, and the time-based timecode increments in the control window once the recording starts. When not recording, with this option selected, the previous session's timecode is displayed. ¦ Note When using VS4Control, this option will only be available on the Master. Drop-frame timecode VS4Recorder Pro gives you the option to use a drop-frame or non-drop-frame timecode in your recording session.
51 Once the peak LED illuminates, the peak indicator no longer appears for the duration of the source recording. ¥ Tip You can reset the VU peak by double-clicking the VU meter in the source window. Peak LED Peak indicator Auto hide When Auto hide is selected, VU meters appear only when mouse activity occurs over the VS4Recorder Pro source windows, and disappear after a period of mouse inactivity.
52 VS4Control status pane The VS4Control status pane is where all pertinent information regarding your VS4Control recording session is located, such as your session’s Multicast IP address (see “Multicast IP address” on page 53), the machine names, and the machine statuses.
53 Remarks • If Input 1 of the Master is disconnected during a capture, the session will continue capturing, but only black frames will be captured on Input 1 of the Master. • To stop the session on the slaves, you will have to disable VS4Control. • If the Master becomes inoperative during the capture: $ The slaves will continue to capture. $ When restarting the VS4Recorder Pro on the Master, the Master will be able to join the group, while the slaves continue capturing.
54 When first opening VS4Recoder Pro, a (valid) default multicast IP address is displayed in VS4Control, but it can be changed (an entered address will be validated). The change must be done on all the machines connected to the same Master.
55 View modes The VS4Recorder Pro interface offers different modes for viewing your input sources. You can choose to view all four input sources simultaneously in quad-view mode, or cycle through isolated inputs for viewing in single-view mode. VS4Recorder Pro also includes a full-screen option for both source-view modes. You can switch between the VS4Recorder Pro view modes at any time without affecting the recording, and all view modes offer the same on-screen display and record functionality.
56 Single-view mode This mode displays only one source window by expanding the selected source window to fill the entire VS4Recorder Pro window area. When in single-view mode, you can cycle through the different inputs using the VS4Recorder Pro shortcut keys (see “Keyboard shortcuts” on page 58).
