Audio Levelling Segments

Audio leveling is possible on audio-only items as well as video segments with audio. This can be done by simply selecting a suitable segment with audio and use VidiEditor's effects panel to adjust the levels by using the slider, the input field or by setting a keyframe. Below figure shows the available controls.

All options can adjust the level of that segment in dBFS in a range between -60 to +15 dBFS. Also, this setting can be reset to its default value of 0 dBFS by clicking the rest button.

After setting audio level adjustments, the adjustment can be monitored using the VidiEditor's peak meter outputting the adjusted audio level for the timeline mixdown (as shown below).

As soon as a level different then 0dB is set for a segment, a small indicator on the timeline's segment displays that the segment has an effect set different from its default values, “fx”. Also a blue line will be displayed on the timeline segment indicating the set gain.

It is possible to adjust the level by simply drag the line. The changed dB value will be displayed in a tooltip while dragging and the value in the settings pane will be updated after releasing the drag and drop interaction.

Copy Paste

In order to make it more convenient for editors, it is also possible to copy the audio leveling effect from one segment to other segments of the timeline. Simply click on the effect in the settings panel and use the keyboard shortcut:

ctr + shift + c

to copy the effect. Then select the segments on timeline that should have the same effect and choose:

ctrl + shift + v

to add the same effect to those segments.

This option will copy over static level setting from one to another segment but will ignore Keyframes if set for a segment.

Keyframe Based Levelling

Besides setting a static level for a complete segment it is possible to set keyframes allowing to adjust the level over time while setting level values for different timecode positions. Using this possibility one can easily fade in or out or to adjust a specific part of a segment building a ramp to adjust the level. To do so simply click the set keyframe button on the setting panel for the selected segment.

This will set a keyframe on the timeline playheads timecode position. It will show up as a dot on the level indicator line.

It is also possible to navigate from keyframe to keyframe while using the arrow buttons. Those will navigate left/right to the next available keyframe of the segment. To adjust existing keyframes it is possible to conveniently select the and move them around on the segment while using drag and drop on left mouse key. Many possibilities exist to work with keyframes. These are listed in following table.
