Compose multiple videos

Arrange up to six slots

Open Create wallpaper layout, choose a target display and add videos by drag-and-drop or +. You can use the same video more than once. The editor uses still thumbnails, not simultaneous live playback. Use horizontal/vertical layouts, drag slots, resize handles or numeric controls. Save the composition to persist edits.

Preserve proportions

Fit and fill preserve video aspect ratio; overflow is cropped at slot edges. Minimum slot size is 5% of the canvas; video zoom is 25–400%. Optional per-slot AI is skipped when either source dimension already meets the slot dimension. Final rendering produces the target canvas rather than an unnecessarily oversized combined file.

Frame rate, length and audio

Output: 24, 30 or 60fps (default 30). Audio is muted by default; you may choose the first AAC track from one slot. The longest clip determines duration, up to 60 seconds. Shorter clips/audio repeat and are trimmed; seamless loop boundaries are not guaranteed.

Supported media and jobs

Eligible MP4/MOV/M4V with one H.264/HEVC SDR video track; no image/GIF composition, HDR, 10-bit or non-square pixels. Canvas sides must be 64–4096px with at most 9 million pixels; odd dimensions are rounded down to even. AI previews, AI conversion and composition share one processing slot. Completed video is added to the library without automatic application.
