View Category:Envelopes -> Inserting & Manipulating a Video Brightness Envelope
Video Brightness Envelopes allows users to control and manipulate the brightness of a segment at any point in the time line. This is a very powerful facility if the user wants to adjust the brightness of selected frames in a track.
To display the Video Brightness Envelope, click on “Show Video Brightness Envelope” icon in the track name. The Video Brightness Envelope will be shown as a red line across the whole track. Nodes can be inserted at the desired positions on the envelope. By repositioning the node the video brightness of the segment at those points will be adjusted.The shape of an envelope will dictate how smoothly or sharply the selected function is applied between nodes.
The shape of any envelope between adjacent nodes can be changed by right clicking on the envelope with your mouse and then selecting an option available from the drop down menu such as Smooth, Sharp, Fast, Slow, etc.
Whilst a node is being moved, a indicator window pops-up at the node position to display the movement of the envelope away from its default position
Note:If the brightness of a track is very low or high, users can adjust the overall brightness level of the track by adjusting the video brightness level slider which is directly below the track name. Adjusting the slider level, together with the brightness envelopes, can produce very good results with segments that have inconsistent brightness quality.
