# Edit AI Video Into Finished, Repeatable Cuts > Edit AI video on a multi-track timeline inside Layer — arrange clips, audio, and text, then rerun the whole edit as a repeatable workflow. Free to start. --- Generating great clips is only half of video production — someone still has to cut them together. For most teams that means exporting AI generations into desktop editing software, losing the connection to the source, and rebuilding the same edit by hand every time a clip, a line of text, or an audio track changes. The Video Timeline Editor puts a real multi-track editor inside Layer. Arrange generated clips, audio, and text on a timeline with a media panel, live preview, and clip inspector — and because the timeline renders as a workflow node, the finished edit becomes a repeatable, re-runnable pipeline instead of a one-off project file. ## Key Capabilities **Multi-track timeline editing** Layer video, audio, and text on separate tracks. The media panel holds your workspace assets, the live preview shows the cut as you build it, and the clip inspector exposes each clip's settings. **Deterministic clip surgery** Trim, stitch, extract a frame, extract audio, change speed, adjust color, and mix multiple tracks — precise, predictable operations that do exactly what you ask, every time. **Edits as workflow nodes** The timeline renders as a node in Layer's workflow system. Your edit is no longer a manual artifact; it's a pipeline step that can be re-run whenever an input changes. **Repeatable, re-runnable cuts** Swap the hero clip, update the end card, replace the VO — then rerun the edit and get the new cut with the same structure. Variant production becomes an input change, not a re-edit. **Everything in one workspace** Generated clips, extended shots, lip-synced lines, subtitled cuts, and music all live where you edit them. No exporting between tools, with 149+ AI models across image, video, 3D, and audio feeding the timeline. ## How It Works **Assemble your media** Pull generated clips, audio tracks, and text from the media panel onto the multi-track timeline. **Cut and refine** Trim and stitch clips, set speeds, adjust color, mix audio across tracks, and place text — watching the live preview as the edit takes shape. **Render — and rerun** Render the finished cut. Because the timeline is a workflow node, the same edit reruns on new inputs, turning one edit into a production pipeline. ## Built for Game Production **UA variant factories** Structure a winning ad once — hook, gameplay beat, end card — then rerun the timeline with different clips, offers, or languages to produce variant sets at test velocity. **Live-ops content on a schedule** Weekly event promos share a format; only the content changes. A timeline-as-workflow makes each week's video a rerun with new inputs instead of a fresh editing session. **Trailers and social cutdowns** Cut generated shots, gameplay capture, and audio into trailers, then derive social cutdowns from the same material — all inside the platform where the assets were made. **Pipelines your whole team can run** Because edits are re-runnable workflows, a producer or marketer can regenerate an updated cut without touching editing software — the structure is already encoded. Layer is the creative platform for 300+ game studios and entertainment brands, including Zynga, SciPlay, Huuuge Games, and Machine Zone.
