Split
Dividing one clip in two — like Narsil breaking before it could become Andúril: necessary, painful, inevitable.
"Split" in video editing refers to two related but distinct concepts. The first is the clip split operation: using the "razor tool" or split command in an NLE to divide a clip at the playhead's current position into two separate, independent clips. Before the split, a single clip occupies the timeline as one continuous piece; after the split, two clips at the same position can be independently trimmed, repositioned, deleted, or have different effects applied. Splitting is the primary mechanism for isolating specific sections of longer clips before rearranging them or applying clip-specific adjustments.
The second meaning of "split" refers to a split-screen composition: a video layout in which the frame is divided into two or more areas, each displaying a different video source simultaneously. Classic split-screen is a 50/50 left/right division with different footage in each half, used in news panels (two talking heads side by side), product comparisons (before/after or competitor/product side by side), or remote interviews (two participants speaking simultaneously). Split-screen compositions can be divided into any arrangement: two horizontal halves, a three-way vertical triptych, a four-quadrant grid, or any asymmetrical division where one element occupies more of the frame than others.
For B2B video, the split operation (razor/split tool) is one of the most frequently used editing actions — it's the primary method for removing unwanted sections from a longer clip (split before the bad section, split after, delete the middle) and for isolating specific portions of footage for individual treatment. Split-screen compositions appear in comparison demos ("here's the old process vs. the new process"), testimonial formats ("hear from multiple customers simultaneously"), and event highlights where multiple simultaneous moments are shown in parallel. The J-cut and L-cut — where audio and video split points are intentionally offset from each other — are a specialized form of split editing where the audio and video tracks of a clip begin or end at different points to create overlapping transitions.
