Roll Relay

Roll Relay turns your camera roll into synchronized video collages. Pick your clips — up to 48 of them — and they land on a single canvas, all playing at once. Drag to reposition. Pinch to resize. Shuffle until it clicks. Or pick a preset: Grid, Stack, Cascade, Scatter. Double-tap any layer to edit it. Trim, crop, adjust volume, reposition. Timeline at the bottom when you need precision. Export in whatever ratio you need — 9:16 for stories, 16:9 for widescreen, 1:1, 4:5. Full resolution. Transparent background option if you want to composite it elsewhere. Dark interface. Metal GPU rendering. Haptic feedback throughout. No account. No watermark. No subscription.
