Slipping Keyrframes in Avid Effects
An important part of effects in Avid is using keyframes. However, it can be difficult to get a hang of using them. There is a specific keyframe graph that can be used to insert keyframes into the video. These keyframes are found in the effect editor. The use of keyframes makes it possible to modify the parameter of a specific keyframe without affecting other keyframes.
Step 1: Select Project
Select the project that will have an effect added. To insert keyframes and add an effect, it is necessary to be in the effect editor. In this editor, it is possible to insert different effects into different sections of the video sequence.
Step 2: Single Keyframe
The preview panel in effect editor will show green bars. To insert a single keyframe, click on a position in the bar. The monitor that shows the position in the video will move to this spot. Select the icon for the keyframe in the bottom of the toolbar to add the keyframe at that spot. The keyframe icon is a pink triangle.
Step 3: Multiple Keyframes
More than 1 keyframe can be added. Like many selection tools, simply hold the shift key and click on all the spots in the position bar where you want to insert keyframes. It is also possible to add these multiple keyframes only to the active parameter, to all parameters, active groups, open graphs, open groups and only the enabled groups. It is possible to add these keyframes to all the parameters except the fixed aspects and tracking.
Step 4: Add Effect
Once the keyframe is added, it is possible to add the effect at this keyframe. The effect will then run until the next keyframe. Think of the keyframes as book stops on the end of the effect. It is necessary to mark the start keyframes when there are many effects being added.
Step 5: Advanced Keyframes
It is possible to promote the effects using advanced keyframes. With advanced keyframes, it is possible to change the order or nested or layered effects. There is a specific icon for this that can be selected when the keyframe is highlighted.
Step 6: Color Correction
Keyframes can be used for color correction. These cannot be added manually within the color correction window, but it is possible to apply color correction to existing keyframes. Keyframes is a very easy way to deal with many complex color corrections. It can be easiest to have a new start keyframe for each new parameter, even if they are overlapping.
Step 7: Redundant Keyframes
It is possible to get rid of redundant keyframes after all adjustment have been made. This is used to get rid of keyframes that are not attached to effects. This is not necessary, but can make all the keyframes easier to work with if you do not have to deal with more keyframes than necessary.
Step 8: Audio
Keyframes can be used for audio as well as visual effects. These types of keyframes can be used to adjust the different levels for the audio track. With these keyframes, it is possible to add audio filters to certain sections. Avid also uses auto gain and clip gain for the level adjustments.
