Detailed Description

This class represents a timeline.

The timeline is one of the most important features of a video editor, and controls all aspects of how video, image, and audio clips are combined together, and how the final video output will be rendered. It has a collection of layers and clips, that arrange, sequence, and generate the final video output.

The following graphic displays a timeline, and how clips can be arranged, scaled, and layered together. It also demonstrates how the viewport can be scaled smaller than the canvas, which can be used to zoom and pan around the canvas (i.e. pan & scan).

The following graphic displays how the playhead determines which frames to combine and layer.

Lets take a look at what the code looks like:

// Create a Timeline
Timeline t(1280, // width
           720, // height
           Fraction(25,1), // framerate
           44100, // sample rate
           2 // channels
           ChannelLayout::LAYOUT_STEREO,
           );
 
// Create some clips
Clip c1(new ImageReader("MyAwesomeLogo.jpeg"));
Clip c2(new FFmpegReader("BackgroundVideo.webm"));
 
// CLIP 1 (logo) - Set some clip properties (with 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 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)
 
// Add clips to timeline
t.AddClip(&c1);
t.AddClip(&c2);
 
// Open the timeline reader
t.Open();
 
// Get frame number 1 from the timeline (This will generate a new frame, made up from the previous clips and settings)
std::shared_ptr<Frame> f = t.GetFrame(1);
 
// Now that we have an openshot::Frame object, lets have some fun!
f->Display(); // Display the frame on the screen
 
// Close the timeline reader
t.Close();
