To provide an exceptional level of control over the components of the video you shoot with the VIXIA HF G20, you will find a range of shooting assist functions normally only available to professional videographers.
Custom Key and Dial
A Custom Key and Dial feature allows you to assign functions to an easily accessible key and adjust the settings with a control dial. They include:
Tv/Av: Use the dial to adjust shutter speed (Tv mode) or aperture (Av mode), as needed. In this mode the key has no effect.
Manual exposure: When manual control is selected, the dial can adjust aperture, shutter speed, or gain. Select items to adjust, such as aperture or other settings, with the key.
Exposure Lock can be set on or off as can the AGC Limit.
Focus and Exposure Aids
To further enhance focusing capability the VIXIA HF G20 also features Focus Assist. It includes enlargement, which helps in capturing your subject in razor-sharp focus. It works by providing a 2x magnification of your subject, which is automatically cancelled when you start recording. This is a feature normally found in professional broadcast-quality cameras. Also included is color peaking, which shows the shooting object's focused areas in actual colors. With Canon's Edge Monitor Focus Assist system, a green monitor is shown at the bottom of the LCD Display. The green waveform shows overall focus of the image, and the height rises to indicate the area in focus. Through this dynamic focus feedback, you can intuitively tune focus in a scene and quickly change the zone of focus.
Typically only found on expensive external units, the VIXIA HF G20 has a waveform monitor built right into the camera. The waveform monitor shows a detailed view of overall image brightness.
Enhanced zebra pattern (70% or 100%) indicates 'blown out' or high brightness areas to help you set the proper exposure.
With the Level Marker feature, it's easy to keep your camcorder level for more professional looking shooting. Line up any horizontal lines in your shot such as the horizon to the marker and you can be sure your camcorder is level.
The Grid Marker helps you compose your shot accurately, by referencing a grid in your viewfinder. Depending on the background color of your shot, you can choose between two different colors for better viewing contrast.
The VIXIA HF G20 features full manual exposure, as well as aperture priority (Av), and shutter priority (Tv) modes.
Either color bars or color bars and test tone can be selected and recorded using a menu. The color bars comply with the SMPTE standard. -12 dB, -18 dB or -20 dB can be selected as the test tone.
The white balance control has six available presets settable through a variety of day and artificial light conditions (Daylight, Shade, Cloudy, Tungsten, Fluorescent H, Fluorescent), as well as two manual white balance settings. Color temperature may also be manually set from 2,000K to 15,000K in 100K increments for more precise adjustment.
Gain may be manually set from 0 dB to 24 dB in 1 dB increments. Additionally, Auto Gain Control Limit allows you to set the maximum gain limit for the image sensor's sensitivity. With this function, brightness and noise can be balanced as required, and image quality can be maximized in low-light situations.
The zoom speed, as controlled by the rocker and handle controls, is selectable, with a choice of variable or 16 fixed speeds, with fast/normal/slow settings for greater control while zooming in various situations.
