Adjusting Color (Color Correction)

Adjust the brightness and color of video in tone, color cast, highlight detail loss, shadow detail loss, etc.

EDIUS has video filters for color correction; 3-Way Color Correction, YUV curve, color balance, color wheel, and monotone. The filters can be adjusted by moving the slider or point.

The following procedure explains the operation of [3-Way Color Correction] as an example.

When you click [Black], an adjustment is made so that the color obtained in the color picker should be black. Similarly, when you select [Gray] or [White], an adjustment is made so that it should be gray or white respectively. If you click [Auto], the color is determined automatically based on the brightness of the obtained color. For example, the color is adjusted to be white when a bright color is obtained.

7Click the part to be corrected in the Recorder.

The color is automatically corrected. You can also adjust the color using the points of the color wheel, or the sliders of saturation and contrast.

Example:

To correct a color-casted white table

Note

Colors appear differently depending on the monitor. Therefore, when exact color adjustment is necessary, output the video to the monitor on which the final video is screened.
If the completed video is broadcasted on TV, adjust the colors within the range of the regulations.
If you check [Safe Color] in [Color Balance] or [Color Wheel] of color correction, the upper or lower limit of brightness and color can be adjusted within a certain range.

Transition and Clip Margin

Transition is an effect that overlays images of 2 adjacent clips and gradually shifts to the next scene. For the overlaying operations, you can use either of the extend mode or fix mode.

For details on the extend mode/fix mode, see the Reference Manual.

Clip Margin Existence

If there is no clip margin, transition cannot be applied in the extend mode (except for the mixer part).

If clips do not have margins, triangle marks are added at the edges of the clips.

If clips have margins, they are displayed as in the following figure.

GPUfx Transition

High quality and complex transitions that use the GPU (Graphics Processing Unit) can be set. A large number of presets are included in the [GPU] effect folder. If you want to set parameters to create a new transition, they can be set and applied from the [Advanced] folder.

The setting dialog box of each transition contains [Design] settings to adjust the motion, lighting, etc. and [Time] settings to specify a key frame for changing the motion along the time axis. These settings can be used to apply complex motion and effects.

To display GPUfx transition, click the [Transitions] tree in the folder view of the [Effect] palette, and click the [GPU] tree.

Note

GPUfx cannot be used if video memory on your PC is smaller than 256 MB. The [GPU] folder also will not be displayed on the [Effect] palette.
To use GPUfx transition, an operating environment that satisfies certain conditions is required. For details on operating environment, see the Grass Valley website.
