Modo de visualización#
Using this pop-up, you can choose between displaying the preview image or a scope that visualizes its color distribution.
Previsualización de imagen#
Previews what the final video will look like, and lets you change the image layout using various tools.
Forma de onda de luminancia#
This scope visualizes the luminosity (brightness) distribution of the image, letting you see at a glance if there’s enough contrast and if any areas are under- or overexposed.
The scope works by plotting a curve for each scanline in the current video frame. Another way of saying this is that each pixel column in the luma waveform is a brightness histogram of the corresponding pixel column in the frame. Specifically:
The horizontal position of a pixel in the waveform refers to a pixel column in the frame.
The vertical position of a pixel in the waveform refers to a brightness value, going from 0 at the bottom to 1 at the top.
The brightness of a pixel in the waveform indicates how many pixels in the above frame column have the above brightness. If no pixels in the frame column have this brightness, the waveform pixel is black. If at least three pixels in the frame column have this brightness, the waveform pixel is white.
When this scope is selected, you have the following option in
:The examples below show two images and their corresponding luma waveforms.
RGB Parade#
Shows three waveforms – for the red, green, and blue color channels – instead of just one for the overall image brightness.
Vectorscopio de croma#
This scope visualizes the color distribution of the image. Each point has:
An angle indicating its hue.
A distance-from-center indicating its saturation.
A brightness indicating how many pixels in the video frame have the above hue and saturation.
Histograma#
Shows three overlapping graphs, one for each color channel. Within each graph:
The X axis corresponds to color intensity, going from 0 on the left (black) to 1 on the right (fully red/green/blue).
The Y axis corresponds to number of pixels.
Use este modo para equilibrar el rango tonal en una imagen. Una imagen bien equilibrada debería tener una distribución buena y suave de valores de color.
