Correction, 2026-10-01: an earlier version said the 8frame canvas has layout tools to frame two clips into a single deliverable and that Nano Banana makes short videos. The canvas has no compositing or layout export, so split screens are assembled in your editor, and Nano Banana is an image model. It also called before-and-after the highest-converting format in direct-response advertising and credited Kling with strong texture handling; we cannot source the first or measure the second.
Split screen is a technique that divides a single frame into two or more sections to display multiple shots simultaneously within the same visual space.
Each section plays its own footage while sharing the frame. The viewer sees both at once, in real time, without a cut. That's the core difference from a standard edit: nothing has to stop for the comparison to happen. Split screen compresses time and space into one moment. It's been a standard tool in film editing for decades, and in AI-generated ad creative it's found a second life as one of the clearest ways to show before-and-after results, product comparisons, or two perspectives on the same event.
How split screen works
The frame is divided by a visible or invisible border. Two-panel splits are most common: left and right, or top and bottom. Three- and four-panel layouts appear in social content and sports broadcasts but are rarer in ad creative because viewer attention spreads thin past two panels.
In a traditional edit, a compositor layers each clip into its own region of the frame using masking or crop tools. The clips can be synchronized (both playing from the same timestamp) or offset (showing different points in their respective timelines). The dividing line can be a hard edge, a soft gradient, or it can move across the frame in a "wipe" style that gradually reveals the second shot.
For AI workflows, split screen is built in post after the individual clips are generated. You generate each panel separately, then composite them. On 8frame, you generate both shots on the canvas, download them, and combine them in your editor.
When you use split screen
Before-and-after. This is the classic direct-response use. A skincare product, a home renovation, a fitness result. The left panel shows the problem state; the right panel shows the outcome. The viewer's eye moves between them automatically. No voiceover needed to make the point.
Product comparison. Two colorways, two formulations, two sizes in the same frame. The viewer can directly compare texture, scale, or finish without watching separate clips. For e-commerce, this makes the comparison easier at the decision point.
Multi-perspective storytelling. Two characters reacting to the same event in real time. A phone call with both sides of the conversation. A live performance and the backstage view. Split screen earns its place here when showing the relationship between two things simultaneously is the narrative point, not just a convenience.
Ad variant review. Running two creative variants side by side in a single file is a fast way to present options to a client or review board. Both creative directions live in one file, no deck needed.
Examples on 8frame
Before-and-after stills with Nano Banana. Generate both states from the same reference image so the angle and lighting match: "same bottle, same angle, unboxed on a plain table" and "same bottle, same angle, styled on a vanity with flowers." Nano Banana 2 is 11 credits an image at 1K and takes up to 10 reference images. Download both and place them side by side in your editor or design tool. The Nano Banana prompts for ad creative variants guide covers prompt structures for consistent variants.
Kling comparison clips. A fashion brief might generate a fabric close-up for the left panel (matte finish) and a matching shot for the right (shiny finish), same lighting, same framing, different material. Start both clips from stills with identical framing so the panels line up, and check that the two takes move similarly, since they are separate generations. Kling v3 Standard is 86 credits for 5 seconds with sound, 57 without; side-by-side panels usually run silent under one music track.
AI variant testing workflow. Generating two creative directions and reviewing them side by side fits the AI ad variant testing workflow. Generate both variants on the 8frame canvas, download them, and build the split-screen review file in your editor.
FAQ
Can 8frame put two clips side by side in one video? No. The canvas has no compositing tool. Generate the panels on 8frame and assemble the split in an editor.
Can Nano Banana make the video panels? No. Nano Banana makes images. Use its stills directly, or animate them with a video model such as Kling or Veo.
