Using Effects With Premiere Pro

The correct answer is that a Position keyframe has been set. This can be inferred from the picture shown, as keyframes are used to mark specific points in time where a property, in this case the Position, has been set or changed. Since there is a keyframe visible in the picture, it indicates that a Position keyframe has been set.

The effect in Premiere used to replace the green background in a clip is called Ultra Key. This effect allows the user to easily remove a specific color (in this case, green) from the footage and replace it with a different background or image. By adjusting the settings of the Ultra Key effect, such as the tolerance and transparency, the user can achieve a seamless and professional-looking result.

In almost all green-screen effects, a mask is created to show the entire background. A mask is used to selectively reveal or hide parts of an image or video. In the context of green-screen effects, a mask is created to accurately separate the subject from the green screen background. This allows the background to be replaced with a different image or video while keeping the subject intact. The mask essentially acts as a stencil, determining which parts of the image or video should be transparent and which parts should be visible.

The property that is NOT being keyframed in the above picture is rotation. Keyframing refers to the process of setting specific values at different points in time to create animation. In this case, rotation is not being animated or changed over time, while scale, position, and anchor point are being keyframed.

For a chromakey effect to work, it is crucial that the background color is consistent throughout. This is because the chromakey technique involves replacing a specific color (usually green or blue) with a different background or image. If the background color is not consistent, it will be difficult to accurately remove and replace that color, resulting in an ineffective chromakey effect.

By adjusting the properties of video clips over time, such as position, scale, rotation, and opacity, we can create the illusion of movement and bring static images to life. This process of manipulating and sequencing images to create the illusion of motion is known as animation.

In Premiere Pro CC, the panel used to select an effect is the "Effect" panel. This panel allows users to browse and choose from a wide variety of effects that can be applied to their video clips. By selecting an effect from this panel, users can then apply and customize it to their desired settings.

The correct answer is Opacity, Pen. Opacity is the property that controls the transparency of an object, and the Pen tool is used to draw free form shapes or masks. By adjusting the opacity and using the pen tool, one can create a mask on a video clip by drawing a custom shape around the desired area.

In Premiere Pro, Chroma Key effects are accomplished by using layered multiple tracks. This means that multiple video tracks are stacked on top of each other, with the top track containing the footage with the chroma key effect applied. By layering multiple tracks, the editor can isolate and remove a specific color or background from the footage, replacing it with a different image or video. This technique allows for precise control over the chroma key effect and ensures a seamless integration of the subject into the desired background.

To achieve a green screen effect, the green screen footage needs to be placed above the background layer. This is because the green screen footage acts as a transparent layer, allowing the background layer to show through. By placing it above the background layer, the green screen footage becomes the topmost layer, ensuring that it covers the background layer completely. This allows for easy removal of the green screen and replacement with a different background during post-production.
