Monitoring using on screen meters
Your Blackmagic Video Assist features useful scopes such as a histogram and audio levels
meter so you can check your exposure and luminance range on cameras, plus monitor the level
of your source audio.
Histogram
The histogram display shows the distribution of the luminance in your video. Pure black is on
the far left side of the display and pure white is on the far right of the display. When the video
signal sharpens to a point at the bottom edges within these limits you’ll know your shadows and
highlights are not clipping, which means details in the tonal ranges of your video are preserved.
Audio Meters
The audio meters shows audio levels for channels 1 and 2 of the input source. The display is
calibrated to dBFS units and features peak hold indicators which stay visible for a short time so
you can clearly see the maximum levels reached. To achieve optimum audio quality, the levels
from your source equipment should never rise above 0 dBFS. If your audio rises above 0 dBFS,
the peak hold indicators will turn red, indicating that audio is clipped.
On Blackmagic Video Assist 4K, tap on the audio meters to reveal the
analog audio level sliders. Drag the sliders left and right to decrease
or increase the audio levelsfor each channel.
