What if the clips have different lengths?

Shortest clip stops the output when the shortest video ends. Longest clip keeps going until the longest one ends, and shorter clips hold their last frame. To make clips start in sync, trim their beginnings first with the video trimmer.

Can I combine portrait and landscape videos?

Yes. Side by side uses a common height with each width following its own ratio; top/bottom uses a common width; in a grid every cell is the same size and each clip is scaled to fit and centered, with the background color filling the rest. Nothing is ever stretched.

🪟Split Screen Video Maker Online - Put Videos Side by Side, Stacked or in a 2×2 Grid

Make before/after comparisons, dual-camera views, reaction videos, virtual choirs or teaching demos. Upload 2–4 videos and choose side by side, top and bottom, or a 2×2 grid (with three clips the fourth cell is filled with the background color); drag files to reorder. Clips with different resolutions, aspect ratios and frame rates are scaled proportionally to a common height or width and normalized to 30 fps, so nothing is stretched. Set the gap between clips and the gap/background color. For audio, keep only the first clip, mix all clips (with a limiter to prevent clipping) or mute. The output can end with the shortest clip or run as long as the longest, with shorter clips holding their last frame. A layout preview updates as you change settings.
