Insert a video at a single time:

Show red, green and blue intensities over time:

Insert a new 1-second video at a single time and show intensities over time:

Insert a new 1-second video at multiple times:

Insert different 1-second videos at multiple times:

Specify times as time quantities:

Specify times using a number of frames:

Display the first five frames in the result:

Specify times relative to the end of the video:

Specify a number of frames relative to the end:

The new content is inserted directly before the relatively specified frame:

Display the last five frames in the result:

Insert new content at detected scene changes in a video:

Compute and display the mean pixel intensity of differences in consecutive frames:

Find scene changes by detecting peaks of the intensity differences after smoothing by 50 frames:

Create "chapter marks" to insert at each scene change:

Insert new videos at each scene change:

Display the first chapter marker and one frame from before and after it:

The properties of the original video, apart from duration, are not changed by default:

Compare video properties:

Insert new content that has different properties:

The input properties are preserved and the duration is extended:

Times outside of the duration of the video will be removed:

Show red, green and blue intensities over time:

Insert new content at two times, the last of which is beyond the duration of the video and not used:

If the new content has a different frame rate than the input video, it will be resampled:

Display frame rates of the videos:

Insert the new video at a single time:

Display frames of the new video:

The new content is resampled:
