Add the Instant Replay component to the server configuration.

The tab allows configuring material profiles for panel export functions.

“1” – one click: press and release the “1” button. [Shift, “1”] – consecutive pressing buttons: Press and release the first button, then the second one. [Shift + “1”] – simultaneous pressing buttons: Press and hold the first button, press the second button, release both buttons. Important! Pressing the button activates the action specified in the button lower section.

To implement the action specified in the button top part, first press and release Shift, then the button with the required action.

The slow motion and instant replay system has several inputs; their number and type depend on the server model. The system also has two outputs: the program output (PGM) and the Preview output (PVW).

The program output serves for playback of prepared replays, and the Preview output serves for real-time viewing and preparing the replay. The Preview output may display the following additional information: TC – the current preview position time code in the HH:MM:SS:FF(*) format. Availability (or not) of the “*” symbol means an even or odd field, respectively. DL – the time difference between the current position and real time. TL – displaying the time left until the end of a clip or playlist. PR – the current playback speed, in percent. Сx – the selected camera, where x is the camera number. PV – indicates the activated Preview mode. Other information may also be displayed on the screen during work.

When using the slow motion and instant replay system, recording must be implemented uninterruptedly on all channels, during the whole sports event, simultaneously with playback of highlights and events editing. The number of recorded tracks corresponds the number of server inputs and depends on the server model.

Enter the Option menu of the panel. Select the Start REC item; use the wheel to move between menu items. Press Enter. To exit the menu, press Clear.

Enter the Option menu of the panel. Select the Stop REC item; use the wheel to move between menu items. Press Enter. To exit the menu, press Clear.

The recording tray is the instrument for working with multi-track video. The tray allows users to navigate the recording, switch between tracks, implement playback with the regulated speed. The tray output always displays a signal from one of the cameras. The tray may be conditionally compared to the multi-track video recorder.

Managing all functions of the replay server is implemented with the professional control panel by JLCooper Electronics, included to the server delivery set.

Selecting cameras/tracks is implemented by the buttons for switching cameras. The “1”, “2”, “3”, “4” buttons go for 1-4 cameras/tracks. The selected button will blink with green. [Shift, “1”], [Shift, “2”], [Shift, “3”], [Shift, “4”] are 5-8 cameras/tracks. The selected button will blink with red. [Shift + “1”], [Shift + “2”], [Shift + “3”], [Shift + “4”] are 9-12 cameras/tracks. The selected button will blink with green/red. The number of recorded video tracks depends on the system model.

Pressing the REC button switches the tray to the mode of working with Live video from cameras (The “LIVE” mode). The system in this mode works as a usual video switcher: buttons switch the live signal from cameras, not recorded video tracks. In the real-time mode, the REC button is red.

The wheel allows free surfing through the recorded video. Any wheel move switches the slow motion and instant replay system to the mode of work with the recorded material. The REC button fades, and the DL value at the Preview output of the system increases, displaying the difference between real time and the recording point, to which the video was rewound.

To start playback, press the PLAY button. During video playback, the buttons for switching cameras switch video tracks. All tracks recorded from cameras are played synchronously, that is why switching tracks during playback is similar to switching cameras at the video switcher. Playback speed will depend on the T-bar position.

By the T-bar you can adjust playback speed of the recorded fragment. The adjusting range of playback speed can be configured in the panel menu. The default value is 0-100%. Any move of the T-bar causes start of playback of the recorded video. If the bar is in its lowest position, and the adjusting range of playback speed is 0-100%, the system outputs a freeze frame.

IN and OUT buttons define the fragment input and output points, setting the replay borders. IN and OUT buttons turn green. In the preview mode, IN and OUT points are defined by the image at the Preview output. Timecodes of IN/OUT points are displayed in the panel screen lower section. The GoTo IN and GoTo OUT buttons instantaneously rewind video to the IN or OUT point, respectively. You can delete the IN point by clicking the Clear button, and then the IN button. The OUT point is deleted similarly: Clear – OUT. After pressing Clear, IN and OUT buttons turn red. If you change your mind about deleting IN/OUT points, press Clear again.

To switch the page, press Page and the 1-10 digit. The current page number is displayed in the Pg section of the panel screen. The system provides 10 pages; each of them contains 10 banks.

To switch the bank, press Shift and the 1-10 digit. The current bank number is displayed in the Bnk section of the panel screen. Every bank contains 10 slots for saving.

Enter the menu: [Option] Exit the menu: [Clear] Switching values: To edit values of menu options, use the T-bar, wheel and number buttons, Enter button (depends on the edited value type).

The slow motion and instant replay system has three main work modes:

• Real-time mode - allows the operator to work with the recording tray for real-time playback of replays and setting markers for further usage.
• Preview mode - allows preparing new fragments for replays simultaneously with playback of the current replay.
• Playlist mode - allows the operator to compose, edit and launch playlists. For example, for creating a summary from interesting game moments.

In this mode, all operator's actions are immediately displayed at the system program output; the same signal is sent to the program output and the Preview output (default mode).

– Wait for an interesting moment.
– Select the needed camera.
– Use the wheel to rewind to the start of the interesting moment.
– Report about the replay readiness.
– Press the Play button by the director's command.
– Adjust the speed of replay playback by the T-bar.

In this mode, the operator can work with the Preview output, whereas the program output implements the replay. Switching cameras and rewinding will be displayed only at the Preview output. To launch the Preview mode, press the PVW button. The PVW button will turn red. In the Preview mode, switching tracks, wheel rewinding and switching to the LIVE mode are implemented only at the system Preview output. In the Preview mode, the T-bar controls playback speed only at the program output and does not affect video at the Preview output.

Important! Note that video at the program and Preview outputs may be from totally different moments of time.

The operator can find the needed position in the recording at the preview output and then send it to the program output with the Take button. Herewith, the video from the program output will be switched to the Preview output. (This option is set in the panel menu: the Swaps PVW” item to On. If the value is Off, images will not be swapped). To exit the Preview mode, press the Preview button again. After exiting the Preview mode, video from the program output is sent to the Preview output, the PVW button fades and all your actions will be displayed at both outputs simultaneously.

The initial position: PVW and REC buttons are red. – Look at the Preview output.

– Use the wheel to rewind to the start of the interesting moment.
– Select the needed camera.
– Report about the replay readiness.

– After the current fragment replay, playback of a new fragment prepared in Preview will automatically start.

For the transition to a random recording point by the time code, implement the following actions:

– Press the GoTo TC button. 
– Enter the needed time code using panel number keys in the HH:MM:SS:FF format (hours, minutes, seconds, frames).
– Press Enter.

In the preview mode, transition to a random point by the time code is implemented only at the Preview output, not affecting the signal sent to the program output.

For transition to the mode of working with a playlist, press the PL button.

To add the current fragment to the playlist end, press Enter. Adding fragments to the playlist is possible in any system work mode. To add a fragment to the selected playlist position, press Insert. If IN and OUT points are set (IN and OUT buttons are highlighted), the fragment limited with In and Out will be added; if IN and OUT points are not set, a 10 seconds fragment will be added (5 seconds before and 5 seconds after).

To delete a selected playlist fragment, press Delete.

To set a marker in the current position, press [Shift+Enter].

• To the first one in recording – [Shift+1].
• To the next one – [Shift+Clear].
• To the previous one – [Shift+Option].
• To the last one in recording – [Shift+10].

A Multi-cam clip allows selecting a camera during its playback. All clips in the database will be considered multi-cam, if their mediaid satisfies the following format: name-{k}, where “name” is the random clip name, k – the video track (camera) number.

Recordings of all tracks are available for viewing and using in the Skylark database right after the start of recording, in the irrec_YYYY_MM_DD folder. Fragments saved to slots are also available in the database. You can create a new NewsCut project, promptly use video recordings and saved fragments for editing, simultaneously to the system work. Playlists are available in the database as CUTS-clips. If you right-click on the corresponding CUTS-clip and select the Edit item, the CUTS-clip will be loaded as the NewsCut project. After editing, the CUTS-clip can be saved again: File→Save Clip. Important: replay system playlists operate only one video track.
