Monitoring & Recording Audio Channels

Located on the bottom left corner of the home screen you will see the Audio panel and quick headphone volume adjustment bar.

Tap the audio bars to bring up the audio panel.

From this panel you can manage up to 12 digital channels (via SDI input) and 8 digital channels (via HDMI input) as well as 2 analogue audio channels (via the XLR Mic/Line in).

Recorded digital audio inputs work in correspondence to the video input source selected from the Input Menu, Analogue Line In is available to both selectable inputs. An active video input is required to record audio.

Each channel has a level meter assigned to Left & Right Channels; when there is active audio feed you will see the level indicator moving.

You can choose to record from any or all of the digital (SDI or HDMI) channels from the active source input as well as analogue inputs.

Underneath each pair of audio channels you can see the  record

button, when this is shown in red it is set to record, simply select the channels you want to record.

The Analogue audio input level is located to the far right, tap   to record this channel.

Please note that if analogue audio is recorded it will be placed as the first pair of audio tracks in the recorded file.

Audio Options

To adjust the gain on the analogue input you need to bring up the audio options page by pressing in the lower right corner of the audio menu.

To select the input line Level to match your device. Options available are;

Line Level (-10 dBV)

Sets the analogue input channel to Line Level via the XLR connections.

Mic Level (-40 dBu)

Sets the analogue input channel to Mic Level via the XLR connections. With Mic Level selected you also have the option to provide 48V phantom power should your microphone require it. Please only use this when your microphone supports it and if unsure please consult the manual for the mic you are using.

Pro Level (+24 dBu)

Sets the analogue input channel to Pro Level Audio to via the XLR connections.

Analogue gain can then be tuned by incremental increase or decrease of up to +/- 20dB individually for both Left and Right channels.

It is not possible to vary the gain if the signal input is from the SDI or HDMI connection because this is digital and is embedded in the

signal. You can usually adjust this from the camera, please see your camera manual for operational details.

To enable phantom power for mic’s connected via the XLR connection, turn on the Mic 48V option.

Audio In must be selected as Mic Level.

For monitoring the audio, the Home Page Audio options Toggles the orientation of the audio bars displayed on the Sumo19 home page in the lower left corner. Options available are;

Horizontal

Displays the 2 channels you are actively monitoring.

Vertical

Displays 12 channels + 2 Analogue Channels.

Monitoring Audio

To monitor the audio, tap the headphone icon  next to the channel you wish to monitor from the headphone output.

Selecting the Monitor icon does not mean that track is selected to be recorded. You need to select each channel using the record button. Tracks that are selected to be recorded have colored Audio

Meters.

Audio Delay

This option allows you to delay the Audio to be in sync with the video by adding in frame delays.

Audio During Playback Mode

2. SDI / HDMI Rolling Timecode Trigger record

If the camera is Record Run mode, recording can be stopped or started by a moving Timecode via HDMI or SDI.

When enabled the camera and the Sumo19 will start and stop recording simultaneously.

Rolling Timecode trigger is for use in older cameras with TC only & no trigger. If your camera is set to FREE RUN this trigger will start recording immediately. Please be that aware not all cameras have Start/Stop flags for triggering record, especially older cameras. In such cases rolling trigger in REC RUN will need to be used to trigger recording automatically at the same time as the camera starts recording.

3. HDMI Camera trigger record

The HDMI Camera trigger is available for supported cameras, There is a flag within the digital signal that lets the Sumo19 know the start/stop record has been pressed on the camera; in turn this will trigger the Sumo19 to start/ stop recording at the same time as the camera.

4. SDI Camera Trigger record

The SDI Camera trigger is manufacturer-specific, you will need to select the appropriate manufacturer for your camera from the input menu. There is a flag within the digital signal that lets the Sumo19 know the start/stop record has been pressed on the camera; in turn this will trigger the Sumo19 to start/ stop recording at the same time as the camera.

To enable this set TRIGGER to the camera manufacturer in the INPUT Menu.

What is Waveform Monitoring?

Waveform Monitoring is used for measuring the brightness, luminance or chroma values from a video input signal. This feature has several benefits to the production workflow including:

• Ensuring camera to camera matching accuracy when shooting
• Returning to locations for additional pick-up
• Assisting with colour
• Camera white and black balance

How to use

To enable the Waveform Monitor, press the Waveform Monitoring icon on the home screen.

Waveform Monitoring icon

The Waveform Monitoring icon will only be visible if there is an input signal detected.

Waveform Monitor Types

Inside the Waveform Monitoring menu, two types of Waveform Monitors are available for use:

Luma Waveform                                 Vectorscope

Vectorscope

RGB Waveform                                  Vectorscope zoom

Luma Waveform, RGB Waveform, Vectorscope and Vectorscope Zoom are enabled simply by touching the corresponding icon and will be by default displayed at the bottom right hand corner.

Luma Waveform

The Luma or Luminance Waveform is a great way to visualize the dynamic range of your image, allowing you to protect exposure of both your high lights and shadow detail. It’s particularly useful when shooting with a low contrast LOG curve and works in perfect partnership with the AtomHDR engine to illustrate the highlight clipping point to allow you to correctly expose you image.

RGB Waveform

RGB Waveform will monitor the level of Red, Green and Blue from an input source. The RGB channels are displayed side by side. This can be used to check to white balance. Just point the camera at something white and the Red, Green and Blue levels should match if white balance is setup correctly on the camera

The Waveform Monitor will remain on screen when hiding the overlays ensuring the focus remains on calibrating your image.

The Vectorscope display shows colour information of hue (shown as a phase vector), and saturation (measured by outward distance from the centre). This is useful for checking if an image is under or over saturated and for calibrating multiple cameras to ensure greater consistency between shots.

Vectorscope Zoom

The Vectorscope Zoom shows a scaled up view (x8) of the centre of the vectorscope.

Waveform Monitor Settings

From within the Waveform Monitoring menu you can access the display settings for the waveform monitor.

To change the size of the waveform, press on the 1/4, 1/3 or Full Screen icons and the display will update immediately.

7.  Display options

How to use

To enable the Monitor Mode functions, press the Monitor Mode icon on the home screen.

Monitor Mode icon

The Monitor Mode icon will be visible even if there is no input signal detected.

Native Video Source

REC 709 SOURCE ICON                                                                                  ATOMHDR ICON

The first option is “Rec 709” which is the Native Source Video. This option will display the video source without any processing. When connected to a camera this means the image you are viewing is the untouched camera output e.g. a standard Rec.709 image, a Rec.709 image with a selected picture profile applied, Log image etc. This may be a standard REC.709 image, a REC.709 image with a selected picture profile applied or an image that is has a LOG curve applied to it.

With this mode selected you have the option to change the screen brightness by adjusting the slider. As you slide to the right the brightness will increase and when at 100% the image will be using the full 1200 NITs of the display. As with any electronic screen device increasing the brightness will increase the power draw and battery life will be affected accordingly.

In this mode adjustments can also be made to the Lift, Gamma and Gain of the display. You can tap the icon on the left of the menu to scroll through the options and adjustments are again made by moving the slider left and right.

The adjustments for Lift, Gamma and Gain are for the display only and will not effect the image being recorded.

The screen adjustments can easily be reset to the default 0 position by tapping the reset icon.

In addition to the screen adjustments you have the option to:

The Display off function allows for the screen to be turned off with out effecting the operation of the unit. This is combined with the screen lock function and will become active by tapping the power on/off button on the side of the unit.

The Tally lights on the front and rear of the unit will still display red for record and and the idle (green) status will be displayed on the front screen LED.

The Flip screen option allows you to invert the screen to meet your needs of operation.

AtomHDR

The second mode option allows you to engage the AtomHDR monitoring mode that allows the processing engine of the Sumo 19 to display the High Dynamic Range capabilities of a Log gamma input. AtomHDR is a result of the research and development by Atomos that allows control of all aspects of the monitor through image processing to deliver the unclipped beauty of spectral highlights through natural, vibrant colors with a result that allows you to simply shoot what you see. When the scene in front of you and the picture displayed on the Sumo 19 look the same your exposure will be correct and when used in conjunction with the wave form monitor you will be able to see the levels and easily train you eye to make accurate exposure settings.

Before entering in to the operation of AtomHDR it’s important to understand the back ground of HDR and we advise that you read the Atomos HDR tech guide to familiarise your self with the key terms and differences between the existing Rec.709 standard dynamic range (SDR) and the future the way we view images in High Dynamic Range (HDR).

One of the key elements to understand is that if your camera can shoot in Log then is can already capture the more dynamic range than you can display in SDR. It in fact preserves the highlight information by applying a Logarithmic curve to compress the additional stops of dynamic range to fit in to the Rec.709 standard. This is why the image appears washed out and de-saturated as each pixel contains more brightness information than SDR can display, if it were to do this it would be brighter than 100 NITs and so be clipped. This is illustrated below:

whilst the screen is inverted take note to respect the air flow and not to obstruct the cooling vents of the unit.

Tally provides control of the rear tally light, allow it to be turned on or off.

AtomHDR cont.

The first step in HDR is to recognize you have a HDR scene. Look for a good range of contrast across the brightest and darkest parts of your image and also across the color and tonal range as each color also contains its own brightness or luminance information.

Secondly ensure you are sending a Log signal into the Sumo19 so that you are recording the HDR Log information. Now you are ready to capture Log but use AtomHDR image processing to resolve the final HDR result in the field rather than dealing with the washed out look of Log for critical exposure decisions

The main impact of HDR is apparent in the spectral highlights and bright areas. Areas that would have previously been blown out will now contain detail and information to enhance your content.

Alongside the physical light in the scene, the faster/brighter your lens the greater the level of brightness you’ll have to play with. Choosing a Cine style lens or those with a delicked manual aperture can provide increased flexibility over photo lenses that use an electronic control aperture.

AtomHDR uses an in depth understanding of each Log curve and combines it with the control of the panel processing and back light in order to apply an increased brightness to the highlight areas of the scene. Start using AtomHDR by selecting the icon and step through the selection process to pick the camera, Log gamma signal and color gamut matching your setup

Camera Manufacturer – tap to scroll through to the manufacturer of the camera providing the input. Sony, Canon, Panasonic, Arri, Red and JVC

Log Gamma Format – For each manufacturer there may be a number of different Log curves available and you can scroll through to the correct selection by tapping the Gamma icon. In the case of Arri there is only LOG-C but you need to set the ASA of the the Log Gamma to match the input of the camera.

Gamut – the third selection allows you to select the Color Gamut of the input. This is not applicable to all cameras but again ensure that this matches the input of the camera to ensure accurate monitoring.

The HDR slider below these allows you to adjust the brightness of the screen to match you scene. Sliding it to the right will increase the dynamic range of the scene and allow you to monitor % or Stop increases over REC.709. The screen is capable of displaying up to 10.2 stops of dynamic range. As you slide to the right you increase the dynamic range the panel reproduces up to its maximum of 10.2 stops. In terms of operation you want to adjust the slider so that the image on the monitor matches the dynamic range of the scene. Leaving it too far down the SDR end of the range means critical highlight detail will be clipped, whereas sliding too far down the HDR end may result in the overall brightness appearing too dark. The easiest way to get this right is to either trust your eyes - judging what you see in reality matches what is on screen or use the Waveform clipping tool (available with OS7.1) that lets you pin point the precise dynamic range for your scene. With OS7.1 a moving graticule or line on the waveform is introduced that illustrates the luminance clipping point. This is illustrated below:

Whilst in AtomHDR mode 3D LUTs can not be used for either display or loop out. We are actively looking in to this and it may change in future Firmware releases. Manual adjustments to the Lift, Gamma and Gain of the screen as the AtomHDR engine is dynamically controlling these.

All adjustments are completely non destructive and will not effect the recording. The adjustments you make to the exposure and color Gamut on the camera will then be out put to be recorded on the Sumo 19.

LOG to Video

LOG TO VIDEO ICON

To load a LUT select the desired slot and press on the blue file icon and then choose from off DISK. Navigate via touching through the disk file system to the LUT file to be uploaded, press on the name to select the LUT and then again to import. Then wait for the LUT loading progress bar to complete. The name of the currently selected 3D LUT is displayed at the top of the Monitor Mode panel.

The third monitor mode LOG to Video allows you to apply a 3D Look Up Table or LUT to the Log image. This allows you to view the Log and convert it to a Rec.709 Luminance with a specific LUT applied for each Log Gamma curve. As with AtomHDR mode you can choose the correct setting by first clicking on the camera manufacturer icon and scrolling through to the appropriate setting. Where applicable you can then scroll through the available Log Gamma Curves and the same process can be applied to the Color Gamut.

Custom Look

CUSTOM LOOK ICON

The fourth mode is for users who are either not working in Log or for user looking to use a custom 3D LUT in order to view aspects of colour management of Log footage.

A LUT or Look Up Table is a table that transforms the color response and as such adjusts the ‘Look’ of the input. 3D LUTs have a combination of three inputs defining the combination of R, G, and B values allowing for adjustment of not only color but also gamma and gamut. LUTs can also be used to monitor the input in a specific color space or more creatively to create a specific ‘look’ such as film stock emulation or to match cameras.

Its worth nothing that not all LUTs are equal and the majority of LUTs are designed to work with in the boundaries of REC.709. This means that whilst they may apply the colour adjustments you are looking for they may also effect the luminance of the image and in which case these LUTs should only be used for delivery of content designed to be viewed in REC.709 or SDR. If you are working with 3D LUTs you can use color correction applications, as well as applications like Photoshop to create you own custom Looks that can then be imported to your Atomos device. They can provide a great base or primary grade that allow you to apply an instant look to your footage.

Atomos support 3D LUTs in the industry standard .CUBE format and provides 8 LUT memory slots for you load your LUTs in to. These can be loaded in from the Built in LUTs or from files created using 3rd party software.

1D LUTs are not supported and will need to be converted via 3rd party software to be imported.

To import LUTs into your Sumo19 first copy the .CUBE files on to the SSD/HDD in your Master Caddy II using a computer and the supplied USB3 Dock.

This LUT can then be applied to the display by selected the correct LUT memory slot. The LUT will automatically be applied to the Display.

Under the display brightness slider there are 3 options that relate to the processing of the LUT.

REC LOOK – If this option is selected to the recording it will bake the LUT look into the recording and this is a non-reversible process. It cannot be undone in Post so we advise you consider your workflow before the use of this option. When enabled, a CUSTOM LOOK icon will flash in the top corner of the monitor and the REVIEW LOOK cannot be activated during recording to avoid any potential issues with the recorded content.

OUTPUT LOOK – With this option the selected LOOK is also applied to both the SDI and HDMI loop outs of the Sumo 19. This will allow for review on a larger monitor or to be used with a wireless sender. This function can also be combined with the down convert option that can be found in the input menu.

REVIEW LOOK – During color management it’s likely that you may want to review a number of LOOKs and even compare them to the Native Video Source.

Tapping the REVIEW LOOK option will apply a 50/50 vertical screen split that will show both the Natural Source Video and the selected LOOK of the LUT.

Please note that activating the 50/50 preview will also be applied to the Loop out.

Atomos Anti-Shock Technology

Spinning disks are very reliable in a controlled environment where movement and vibration are minimal and within the capabilities of the devices. They are ideal for low-cost recording, but will suffer reduced performance if they are jolted or receive a sudden impact.

If a large enough shock occurs a break in the recording may occur. In this case the Sumo19 will automatically start a new recording once the drive recovers.

This means that even if you suffer a momentary break in your recording, the video capture will continue without any intervention from you, the user.

It is obviously important for you to know that you have suffered from an interrupted recording and the user interface will display a warning (in the form of a Kangaroo sign) clearly in the top left hand corner of the display.

Skippy Warning

To remove “Skippy” warning, simply touch the icon and it will disappear.

File Recovery

The Sumo19 continuously writes to disk while in recording mode. If the power fails or the drive is removed accidently all but the last few seconds of the clip can be recovered

In the event of an interrupted recording, when you restart the Sumo19, or enter playback mode, you will be presented with a menu that gives you the option to recover immediately, or recover it later.

If you select recover later, every time you put the disk in, or start up the Sumo19, the same menu will appear to prompt you to recover the file that did not close properly.

If the drive is broken, or has become corrupted, then we will not be able to recover the file and we recommend that you try third-party hard disk recovery software
