Instructions for the 1070 Asynchronous Light board Studio are organized by item type and order of setup.
- Make sure the light board is plugged into the wall via the extension cord. The lights are already attached to the light board. You can change their brightness using the dimmers at the side of the board.
- Adjust the presenter lights: Using the two dimmers closest to the backdrop, set the brightness of the presenter light dimmers by aligning the orange markers (about half brightness).
- Adjust the board lights: Turn the furthest dimmer to full strength. These LED lights are contained within the board and make your writing visible.
- Note that if you are ever unsure which dimmer controls which light, stand behind the board as you will for recording and adjust the brightness on the dimmers one at a time.
Spreader and Manfrotto Tripod:
- If you need to lower or raise the tripod, open the upper clasps. Note that the tripod clasps open on the silver side. Do not alter the lower tripod clasps as they are fully extended.
- Adjust tripod height. Firmly hold the head of the tripod with one hand and open all three clasps with the other hand. Lift or lower the tripod with one hand and close each of the clasps with the other.
- Try to get the tripod legs as even as possible.
- Lock pan and tilt: Pan and tilt are controlled by the levers you can turn at the top of the tripod head near the two vertical red arrows with “LOCK” on them.
- Pan and tilt must be locked before you can attach the camera. Turn the levers clockwise to lock these features.
- Prepare the tripod head to attach the camera. Go to the tripod head, the top part of the tripod. Simultaneously push down on the black paddle with your thumb and use your fingers to push the silver lever over the notch on the black paddle as it is pushed down.
- The silver notch on the lever should catch on the black notch on the paddle, locking the lever in position. You are now ready to attach the camera plate to the tripod head.
Canon Rebel T8i Camera Kit:
- Insert the battery: Turn the camera so you can see the bottom. There is a compartment labeled “BATT OPEN”.
- Push the lever inward to open the battery compartment.
- Line up the four pieces of metal at the bottom of the compartment with the battery’s four lines.
- When inserting the battery, push against the gray notch. It can be a little tricky to get the battery in, so if you are having trouble, pull the notch back with one finger and slide the battery in.
- Attach the camera to the tripod: The silver plate underneath the camera allows you to set the camera on the tripod.
- Step behind the tripod with the camera’s “user” side facing you. The user side contains all the buttons while the lens side contains the lens.
- Lock the camera onto the tripod head by sliding the lens-side camera plate on top of the tripod head and then setting the entire plate flat.
- You should hear a click as the silver lever is released from the paddle and locks the camera in place.
- Level the tripod: Grip the top of the camera with one hand and find the knob attached to the user-side red arrow that faces vertically on the tripod (rather than the two horizontal ones you checked for pan and tilt). The green circle with a bubble in it at the user-side of the tripod head is a level.
- Loosen the knob and move the camera until the bubble is in the center of the level. Then tighten the knob.
- Attach the lens to the camera: If the lens is not already attached to the camera body, remove the black cover from the sensor on the camera and remove the cover from the lens by turning counter-clockwise on both. Do not leave the sensor on the camera or the lens uncovered for longer than it takes to attach the lens. Camera sensors are extremely light-sensitive and exposing them for long periods of time will destroy them.
- To attach the lens to the camera body, line up the white square on the lens with the white square on the camera body, which is in the 11 o’clock position. Turn the lens clockwise and make sure you are turning the part of the lens closest to the camera body and not one of the focal or aperture rings.
- When the lens is secure, you will hear a click. Before releasing the lens, place one hand directly underneath the lens and let go of the lens with your other hand.
- Recharge the battery after use: Recharge the battery during breaks in filming and overnight before your next day’s shoot. Always turn the camera off before removing the battery or SD card.
- Insert a lithium battery into the CRR8 receiver if one is not already there.
- Attach the microphone receiver to the camera. Mount the CRR8 receiver onto the camera with the antennas facing the board. Extend the antennas. They communicate with the receiver.
- Plug the CRR8 receiver into the camera’s right side microphone jack. The camera should be off.
- Turn the VOL/PWR knob on the receiver to MIC. Turn the volume knob to the 11 o’clock position. Note that depending on the volume of your voice, you may want to decrease or increase the volume.
- Synch the receiver and transmitter. Open the battery pack on the transmitter. Make sure two AA batteries are loaded. Press and hold the power button momentarily on top of the receiver until the indicator light turns green. Check that the microphone transmitter and receiver are on the same channel.
- If the transmitter and receiver are not synched, press the CHANNEL button on the receiver to navigate between sixteen channels, numbered 0-9 and A-F. Select any channel. Then hold down on CHANNEL until the number or letter you selected blinks.
- Now hold the transmitter facedown and line the transmitter’s IR light indicator with the receiver’s IR light indicator. The READY/PEAK light on the receiver will turn green when the receiver and transmitter are synced.
- Attach the microphone to your collar: Clip the microphone to your shirt collar directly beneath your mouth. Clip the transmitter to the waist of your clothing. A belt works best.
- Recharge the battery after use: Recharge the lithium batteries during breaks in filming and overnight before your next day’s shoot. Turn the receiver and transmitter off before removing batteries.
- Turn the camera on: Move the lever on top of the camera from the Off position to the video camera icon position (past the On position).
- Check the camera modes: The camera mode should be set as M(manual) on the top of the camera.
- Check that the lavalier microphone is selected as your audio input: Press the MENU button and hit OK. The camera monitor is a touch screen so you can press directly on it or use the arrows near the Menu button.
- Go to the first page in the menu, “Shooting settings” and select “Sound recording.”
- Now check that Sound rec. is set to Manual. If it is not, select Sound rec. again and then select Manual. Manual is the lavalier microphone input.
- Set the audio levels: Speak into the microphone at the same volume you plan to speak at while recording. Watch the Left and Right channels fluctuate on the screen.
- Your audio should be fluctuating around -12 dB and the bars should be yellow. You want to avoid red bars when speaking and do not want your volume to hit 0 dB.
- If you find you are not hitting -12 dB, turn the volume up slightly using the VOLUME knob on the receiver and if you are peaking (or hitting 0), turn the volume down slightly.
- In a completely dark room with both sets of presenter lights adjusted to the levels indicated by the orange tape, the ISO should be 800 and the aperture should be 5.6. The camera setting, as indicated on the dial on top of the camera body should be set to “M” for manual.
- Autofocus will automatically be on so when you hit record and step behind the light board, wait three seconds for the focus to adjust before starting your lecture.
- Check focal length: The lens should be set to 35 mm, which will create a large depth of field and ample board space within the frame. Adjust the focal ring on the lens to 35 if it is not already set.
- Return the lens cap when you are not filming: Lens sensors are extremely light-sensitive and will last longer if they are covered when not in use.
- Tip: misplacing the lens cap is common so store it in the camera case each time you remove it.
- With the lens set to 35 mm, you should not need to reframe. To determine how much space you have to write, mark an ‘X’ in each corner of the board with a black marker, indicating the area which will be recorded by the camera. Because of the black backdrop, only the presenter will see the markings. Some people actually pre-write everything on the board in black marker and then trace over it with a neon marker while filming.
- Remember that capturing too much of the frame, like the edge of the light board or your border markings, can be fixed by scaling in post-production. However, cutting off your writing or yourself, cannot be fixed in post-production because the camera did not capture that information. Only what is visible on the camera’s monitor will be recorded and visible for post-production and the final video.
Recording and Playback
- Start and stop recording: Press the small camera icon button near the viewfinder at the top of the user side of the camera to start and stop recording.
- Playback a recording: Press the triangle button to the right of the camera’s monitor on the user side of the camera. After you have finished watching a recording, press the playback button again or press the record button.
1080 Synchronous Studio
Magewell Capture Card and Podium Computer:
- First set up the tripod, camera, and camera and microphone settings, as found here.
- Attach the mini HDMI cord to the camera. Once you connect the mini HDMI cord to the camera, you will not be able to view camera settings because the camera now functions as a webcam on the podium computer or your laptop.
- If hosting a Zoom meeting, check that the Magewell capture card is connected to the podium computer via the blue USB cord with orange tape. The podium computer is connected to the monitor so you can see yourself and the participants in your call.
- If recording in Camtasia, plug the blue USB cord with orange tape into your laptop USB 3.0 port.
- If you are recording a Zoom session for the first time, you must enable Zoom cloud recordings.
- Open your Zoom meeting.
- Select audio and video inputs.
- Choose Mic (USB Capture HDMI+ Mic) as your microphone.
- Choose USB Capture HDMI+ as your camera.
- Turn off image mirroring.
- From the video settings, open Advanced Settings. Make sure that Mirror Image is not selected so that you can view your video just as your students.
- Turn on the monitor. You will use this to see your students during synchronous sessions. Do not move the monitor as it is angled to prevent glare on the light board.
- The podium computer is already set to duplicate its desktop on the monitor, so you will see everything that is open on the podium computer.
- You are now ready to begin your call. You can see participants on the monitor and speak to them from behind the light board.
- If you have not used Camtasia before, set up a meeting with Teaching & Learning at firstname.lastname@example.org.
- Camtasia recordings require you to bring a laptop with Camtasia installed to Grainger Hall.
- Open Camtasia.
- Select “New Project” or "New Recording".
- If you select New Project, click “Record” in the top left corner.
- Turn off the leftmost tab to disable screen recording, labelled “Color LCD” below. Turn off system
- Select audio and video inputs.
- Choose “USB Capture HDMI+” as your video input.
- Choose “USB Capture HDMI+ Mic” as your audio input.
- Click “Start Recording” to record.
Before leaving the studio, please disinfect all surfaces you touched with a cleaning cloth, including the camera buttons and screen, lavalier microphone, light dimmers and switches, markers and glass cleaner, podium computer, and any cords with which you may have come into contact. Never spray disinfectant directly on an electronic.
A good practice is to disinfect items as you reset them. To reset:
- Turn off the camera
- Place the lens cap on the camera
- Turn off the lavalier transmitter and receiver
- Return the lavalier transmitter to the light board table
- Wipe down the light board
- Turn off all light board lights
- Disconnect your laptop from the Magewell USB capture card (if recording in Camtasia)
- Log out of the podium computer
- Charge the camera and lavalier receiver batteries
- Turn off room lights and lock the door
