A video collage places multiple video clips side by side in a single frame. This format is widely used for reaction videos (original content on one side, reaction on the other), before-and-after comparisons, multi-angle footage, and compilation content.
CreatorMedia Studio's Recaper and Video Editor tools support combining video clips into collage layouts without any desktop software.

Navigate to Video Editor from the dashboard. The collage/combination feature is available in the layout settings panel.
Upload the video clips you want to combine. You can use 2 or more clips. The preview panel will show how they will be arranged.
Select from available collage layouts — side by side (50/50 split), stacked (top/bottom), picture-in-picture, or custom proportions. Choose the layout that best suits your content.
Choose your target aspect ratio — 9:16 for vertical social content, 16:9 for YouTube and desktop, or 1:1 for Instagram. The clips will be automatically resized and cropped to fit.
