You can adjust everything about the image via a quick-access menu that allows you to see the changes you are making in real-time.
You can choose between three camera modes to operate in: Auto, Shutter, and Manual. The difference between these is how exposure, shutter speed, and ISO settings are controlled.
Selecting Auto will cause both shutter speed and ISO settings to adjust on their own to create the best shot possible based on the lighting in your environment. You will not be able to manually adjust these settings in this mode, but you can adjust exposure and all other settings in this menu as needed.
Shutter priority mode allows you to dial in the minimum shutter speed manually, while the ISO setting automatically compensates to create smooth movement within the shot. This is ideal for a producer working in extremely fast or extremely slow environments who wants the camera to adjust based on changing lighting (e.g. sunset).
For full control of both shutter speed and ISO, select Manual. Exposure cannot be adjusted since it is a combined value and will automatically dial in based on how you set your shutter speed and ISO setting.
Choose this setting if you prefer to have full control, or if you are looking to showcase a change in lighting from one environment to another with no camera adjustment period. For example, if you are starting indoors but moving outdoors, you may want to manually set your shutter speed and ISO for optimal appearance for outdoors, which will keep your indoor environment looking darker.
This setting is typically used to compensate for environments with contrasting lighting conditions (stage with spotlights, etc.) It can be adjusted when the Camera Mode is set to Auto or Shutter.
Keep in mind that adjusting this setting will cause the shutter speed and/or ISO to automatically adjust.
This setting can be found to the right of the Camera Mode menu; tap it to open the menu and select an exposure measurement.
By definition, shutter speed determines for how long each individual frame is exposed, measured in fractions of a second. This setting has the most impact on the appearance of motion blurriness in your video. Vimeo's blog has a great demonstration of this. You can configure this when the Camera Mode is set to Shutter or Manual.
ISO measures the image sensor's sensitivity to light. Higher ISO settings are ideal for darker settings, although will produce grainier shots than lower ISO settings. ISO can only be manually adjusted when the Camera Mode is set to Manual; it will automatically adjust in other modes.
White balance can be found to the left of the ISO setting. This generally refers to the color balance in the image; in other words, the camera determines what in the image is white, and adjusts the other colors accordingly. The Mevo App can auto-white balance your shot or you can manually choose from a few preset environments.
Tap the White Balance setting to open the menu and scroll down to choose your setting. The camera will take about one second after selecting an option to adjust the image so you can see what your picture looks like after.
Brightness, Contrast, Saturation
Brightness, contrast, and saturation are adjustments best made to your shot after you've established your Shutter speed and ISO settings.
Tap the desired setting and scroll up or down to choose an option; the Mevo App will adjust the image based on your selection.
View angle is only available for the Mevo Plus and First Generation cameras.
You can adjust the appearance of the field of view with the view angle setting. This menu can be found to the right of the Sharpness menu. Tap it to select among a handful of options.
As a reference, here is a picture of the same exact sample area taken by an iPhone 6S Plus at the same distance as the Mevo camera.
Flat: most cropped, straight edges
Narrow: wider field of view, edges slightly curved
Wide: Full field of view captured, curved edges
Fisheye: Most curved edges, objects in the middle of the picture appear closer to the camera.
Metering & Exposure Metering
Metering is deciding on where the adjustments are taking place (Wide or Crop). Exposure Metering is selecting where within the selected frame to adjust exposure (Spot, Center, Average). This setting tells the the Mevo App where within the field of view light should be measured. It's found to the right of the View Angle setting.
- Wide: measures exposure of the entire shot and keeps the exposure consistent regardless of cropping.
- Crop: measures the exposure of the cropped portion(s) of your shot.
If you select Crop, the exposure will adjust based on the lighting in the cropped area. Your viewers will notice a change in lighting if you crop from a darker area to a brighter area.
This setting allows you to have your video flip vertically and is located to the right of the Metering setting. Tap the menu and choose among the three options
- Off (Not Flipped): The image will not flip if you turn the camera upside down.
- On (Flipped): The image will appear flipped unless you physically turn the camera upside-down.
- Auto: The app will detect whether the camera is right-side-up or upside-down and adjust the orientation accordingly.
- Please note: it may take a few seconds before the image flips, so we do not recommend going back and forth between the two orientations frequently.
When you choose a setting, you will see a notification in the upper left corner indicating that your video is in the process of inverting or reverting to normal.
Electronic Image Stabilization
Electronic Image Stabilization (EIS) helps retain the video quality while the camera is in motion. Customers looking to use the camera while moving rather than in a stationary location may be want to consider turning EIS on, although doing so will disable the cameras live-editing features (zoom, pan, cut, etc.).
Find the EIS menu to the right of the Flip menu. Tap it to open the menu; you can either turn it On or Off. A notification of EIS being enabled or disabled will appear in the upper left corner when you choose a setting.
Anti Flicker is a setting that you should check if you are in a room with fluorescent lights or you plan on shooting a television screen. Many times when using a camera in these environments, there is a noticeable flicker in the image. This setting helps reduce this flicker.
Here you have four options:
- Off: Anti flicker is not active.
- 60Hz: Configured for US power frequency
- 50Hz: Configured for European power frequency
- Auto: Automatically detects and matches power frequency
This is the last menu in the top row of the adjustments menu, to the right of the EIS menu. Tap it to choose your Anti Flicker setting.
There are a few preset image filters you can use to give your event a different look and feel. These are all found in the bottom row of the Adjustments menu (swipe the row left to see all the filters).
- Back Lit
- High Contrast
- Black White
The Custom option will automatically be selected when you start configuring any of the image adjustments in the top row of the menu (Shutter speed, white balance, etc.), regardless of which preset you originally selected.
If you switch to a different preset, the Mevo App will remember the last configuration you had under Custom; if you select Custom again, the image will revert back to the adjustments you made previously.
The drop-down arrow on the far right will close the Adjustments menu.
