ClipToolbox

Split-screen and grid video maker

Merge two or more videos or photos into one frame with Scene Builder: side by side, stacked, a 2x2 grid, or a custom grid you resize by dragging the borders. Pick which frame you hear or mix them all, and crop, trim and position each one - then cut to a different layout later in the same video.

Open Scene Builder

Steps

  1. Open Scene Builder and add your sources.
  2. Split the frame into as many cells as you need, drag the borders to resize any of them.
  3. Drag inside a cell to choose the part that shows; trim each one and set its volume.
  4. Pick which frame is audible or mix them all, then export one MP4.

FAQ

Can I resize the cells?

Yes. Drag the border between any two frames to make one bigger and the other smaller.

Can I change the layout partway through?

Yes - that is the difference from a plain split screen. Add a cut and arrange a new layout from there; the video switches at that point.

Can I mix photos and video?

Yes, any frame can be a photo or a video clip.

Is this the same as merging videos together?

Close - merging usually means joining clips one after another. Scene Builder puts several sources in the frame at once, side by side or in a grid, with each one’s own timing.

Which frame’s sound is used?

Pick one frame, or mix them all together with a volume per frame.
