Detailed Description

This class represents a clip (used to arrange readers on the timeline)

Each image, video, or audio file is represented on a layer as a clip. A clip has many properties that affect how it behaves on the timeline, such as its size, position, transparency, rotation, speed, volume, etc...

// Create some clips
Clip c1(new ImageReader("MyAwesomeLogo.jpeg"));
Clip c2(new FFmpegReader("BackgroundVideo.webm"));
// CLIP 1 (logo) - Set some clip properties (with openshot::Keyframes)
c1.Position(0.0); // Set the position or location (in seconds) on the timeline
c1.gravity = GRAVITY_LEFT; // Set the alignment / gravity of the clip (position on the screen)
c1.scale = SCALE_CROP; // Set the scale mode (how the image is resized to fill the screen)
c1.Layer(1); // Set the layer of the timeline (higher layers cover up images of lower layers)
c1.Start(0.0); // Set the starting position of the video (trim the left side of the video)
c1.End(16.0); // Set the ending position of the video (trim the right side of the video)
c1.alpha.AddPoint(1, 0.0); // Set the alpha to transparent on frame #1
c1.alpha.AddPoint(500, 0.0); // Keep the alpha transparent until frame #500
c1.alpha.AddPoint(565, 1.0); // Animate the alpha from transparent to visible (between frame #501 and #565)
// CLIP 2 (background video) - Set some clip properties (with openshot::Keyframes)
c2.Position(0.0); // Set the position or location (in seconds) on the timeline
c2.Start(10.0); // Set the starting position of the video (trim the left side of the video)
c2.Layer(0); // Set the layer of the timeline (higher layers cover up images of lower layers)
c2.alpha.AddPoint(1, 1.0); // Set the alpha to visible on frame #1
c2.alpha.AddPoint(150, 0.0); // Animate the alpha to transparent (between frame 2 and frame #150)
c2.alpha.AddPoint(360, 0.0, LINEAR); // Keep the alpha transparent until frame #360
c2.alpha.AddPoint(384, 1.0); // Animate the alpha to visible (between frame #360 and frame #384)
