Best AI to Make Split Screen Videos
Keep viewers watching longer — pair your clip with a proven retention background in one step.
Split screen videos place the creator's main content clip on the top half of a 9:16 vertical frame while a secondary background clip runs continuously on the bottom half. The dual-stream layout keeps visual motion constant even when the primary content is static or slow-paced, which is the primary reason split screen videos achieve higher average watch time than single-clip content. The format is widely used by commentary creators, educators, and podcast channels repurposing their content for TikTok and Shorts.

Frequently asked questions
What's the best AI to make split screen videos?
Korpi AI is one of the best tools for split screen videos because it combines your uploaded clip with a background video from a curated viral library and renders the 1080x1920 vertical output automatically — no editing software required. It removes the main friction point of sourcing and syncing a secondary background clip.
Why do split screen videos get better watch time on TikTok?
Split screen videos maintain continuous visual motion across the full frame even when the top-half content is a talking-head or static scene. The continuous movement in the background triggers the brain to keep watching rather than scroll, which is why average watch time and completion rates are typically higher than single-clip content.
Can I use any video for the top clip?
Yes. Korpi AI accepts any uploaded video file for the top half of the split screen. The background clip for the bottom half comes from Korpi's curated library of proven viral footage.
What types of background videos perform best for split screen?
Satisfying continuous loops — gameplay, outdoor scenes, food preparation, or relaxing visuals — work best as backgrounds because they provide constant motion without competing for the viewer's attention on the main content. Korpi's library is pre-curated for this purpose.
