How to add the transition between 2 video fragments?

Product: Video Edit SDK .Net. Engine: VideoEditCore (Windows only).

Sample code​

In this article, we add a simple transition between 2 video files (parts of them).

1. Add 2 video fragments from 2 video files, each 5 seconds (5000 ms) long​

The first fragment is located in the first 5 seconds on the timeline, and the second fragment is located between 4 and 9 seconds, so the second video overlaps the first video. This 1-second overlap will be used as a transition between videos. Each transition except fade-in/out requires this.

string[] files = { "!video.avi", "!video2.wmv" };
FileSegment[] segments1 = new[] { new FileSegment(TimeSpan.FromMilliseconds(0), TimeSpan.FromMilliseconds(5000)) };
var videoFile = new VideoSource(
        files[0],
        segments1,
        VideoEditStretchMode.Letterbox,
        0,
        1.0);
        
FileSegment[] segments2 = new[] { new FileSegment(TimeSpan.FromMilliseconds(0), TimeSpan.FromMilliseconds(5000)) };

var videoFile2 = new VideoSource(
        files[1],
        segments2,
        VideoEditStretchMode.Letterbox,
        0,
        1.0);

VideoEdit1.Input_AddVideoFile(
        videoFile,
        TimeSpan.FromMilliseconds(0));

VideoEdit1.Input_AddVideoFile(
        videoFile2,
        TimeSpan.FromMilliseconds(4000));

2. Get the ID of the required transition​

int id = VideoEdit.Video_Transition_GetIDFromName("Upper right");

3. Add a transition between 4 and 5 seconds on the timeline​

 VideoEdit1.Video_Transition_Add(TimeSpan.FromMilliseconds(4000), TimeSpan.FromMilliseconds(5000), id);

Transition names are available using the "VideoEdit.Video_Transition_Names()" call. Also, you can check the IDs list in this article.
