Video Split ## What this node does **Video Split** splits a clip into a **before** part and an **after** part at the timestamp **split\_s**. It's a real re-encode on the server (PyAV / ffmpeg): on **▶ Run** it trims the clip twice (0 → split, and split → end) and saves both as project snapshots. Input is `COMFYTV_VIDEO`; it has two `COMFYTV_VIDEO` outputs. The split point must fall inside the clip — roughly between 0.05s and (duration − 0.05s) — or the run errors out. ## When to use it * Break a long take into two shots so you can treat each one separately (retime, color, etc.). * Isolate a section, then feed one half into Video Concat with other material. * Drop a mid-clip transition point. ## Parameters ### split\_s The cut point, in seconds. Range **0–3600**, step 0.01, default **0.0**. Must land strictly inside the clip; a value at or beyond the ends is rejected. Everything before this time goes to **video\_a**, everything from it to the end goes to **video\_b**. ## Outputs | Output | Type | Meaning | | ------------ | --------------- | --------------------------------------------------------------- | | **video\_a** | `COMFYTV_VIDEO` | The part before the split point (0 → split\_s). | | **video\_b** | `COMFYTV_VIDEO` | The part from the split point to the end (split\_s → duration). | Both parts are persisted as snapshots; **video\_b** is emitted as the "picked" side of the same run. ## Tips * The default 0.0 is not a valid split — set a real timestamp inside the clip. * Duration is read from the clip automatically; the split must sit at least \~0.05s away from either end. ## Bridge note `COMFYTV_VIDEO` is a project snapshot reference, not a native ComfyUI tensor. To move between ComfyTV and native ComfyUI nodes, insert a **Bridge** (`ComfyTV/Bridge`). See [https://github.com/jtydhr88/ComfyTV/blob/main/docs/bridges.md](https://github.com/jtydhr88/ComfyTV/blob/main/docs/bridges.md). ## Related nodes * **Video Clip** — trim to an arbitrary in/out range instead of a single cut. * **Video Concat** — rejoin the two halves (with or without other clips).
