Insert Video Clips
The Insert Video Clips block takes a base video and splices one or more overlay video clips into it at specified timecodes.
Insert b-roll clips into a base video at timecodes
The Insert Video Clips block takes a base video and splices one or more overlay video clips into it at specified timecodes. You provide a base video URL and an array of overlay videos, each with its own video URL and a start time in seconds indicating where it should be inserted. The block also accepts optional parameters for controlling transitions between clips, including a transition type and a transition duration, giving you control over how cuts are handled.

What are the required parameters for this block?
The required parameters are baseVideoUrl, which is the URL of the base video, and overlayVideos, which is an array of objects each containing a videoUrl and a startTimeSec value indicating where in the base video the clip should be inserted.
What does the block return?
The block stores its output in a destination variable specified by the destinationVar field. The output metadata does not define additional named output fields beyond this variable assignment.
Can I control how clips transition into each other?
Yes. The block accepts an optional transition parameter for specifying the transition type and an optional transitionDuration parameter for controlling how long the transition lasts. These correspond to xfade-style transitions applied at the insertion points.
Can the block use the audio from the overlay clips instead of the base video?
Yes. The optional useOverlayAudio parameter, when set to true, will use the audio track from the overlay video clips rather than the base video audio at those points.
What kinds of workflows is this block suited for?
This block fits into video production and editing workflows where a base video needs to be augmented with additional footage at specific times. It can be used in automated content pipelines, AI-assisted video assembly, or any workflow that programmatically constructs a final video from multiple source clips.
