Pinnacle Liquid Edition 6 for Windows

Classic filters work with or without keyframes, and so you can edit following the same procedure you did when you edited Realtime filters. However, there are a number of additional parameters for you to adjust. You need to look at each filter in turn to see to which extra parameters you can gain access.

Keyframe Interpolation

One of the most interesting parameters available using Classic filters is Keyframe Interpolation. This governs the speed at which the effect happens between any two keyframes.

Remember; this is the "speed at which the effect happens" and not the "speed of the actual clip." You can only alter the speed of a media clip using the Timewarp non-Realtime filter, which I discuss later in this chapter.

You use Keyframe Interpolation simply to alter the pace of an effect. The following example shows a 2D Editor using this parameter to zoom in on the incoming clip. This happens slowly at first, then when it reaches the halfway mark, the zoom increases in speed until it reaches full speed at the end of the clip.

To alter Keyframe Interpolation

1.

Add one of the Classic filters to a clip on the Timeline.

2.

Scrub to a keyframe on the Timeline and alter the interpolation in one of the following ways:

  • Drag the acceleration line toward a positive (faster) or negative (slower) amount.

  • Double-click inside this box and enter a number.

  • Click inside the parameter curve area and drag the keyframe toward the value you require.

3.

Exit the editor by clicking the Running Man button in the top-right corner of the editor.

The editor exits and the filter begins to render in the background.

4.

Once it has finished rendering, set a mark-in and mark-out point on the Timeline on either side of the filter.

5.

Then play back the filter by clicking the Play from Mark-In to Mark-Out button.

Tip

  • If you add a Keyframe Interpolation of 100 to the first keyframe, the effect happens immediately.
