视频｜HappyHorse 1.0 视频编辑

The one HappyHorse node that takes a video in and gives a changed video back. Feed it a source clip plus an instruction - "replace the background with a sunset beach, keep the person's movement, add a warm filter" - and up to five reference images, and it re-renders the original footage with the edits applied. The edit node is the family's most useful commercial tool: background swaps, regrades, subject swaps, and motion tweaks without re-shooting or reaching for a heavyweight video editor.

The honest caveat up front: "video editing" on a closed model like this is not frame-accurate compositing. It's a re-generation conditioned on your source video and instruction - the motion and identity usually survive, fine details and exact frames don't. For a background swap on a talking-head or product clip, it's great. For "fix this one typo on that sign at 00:14," it's the wrong tool. Set expectations accordingly and you'll be pleasantly surprised more often than not.

How it works

Source video can come in three ways: a 视频URL (recommended - a public URL, used when present), a 本地视频 VIDEO tensor, or a plain local path. Large local files hit the inline upload limit and the docs recommend the URL route for anything substantial. 参考图1–参考图5 (or the 参考图URL列表 field) are optional style/identity anchors for the edit - for example, a reference that pins down the new look you want. The node submits to HappyHorse's edit endpoint, polls, downloads, and returns the standard five outputs: 🎬_视频输出, 📁_本地保存路径, 🔗_视频云端链接, 🆔_任务ID, 📄_完整日志.

The inputs that matter

• 编辑指令 - the whole game. Say what changes and what must not: "replace the background with X, keep the person's movement, add a warm tone." The default template is a good skeleton.
• 视频URL / 本地视频 - the source footage.
• 参考图1–参考图5 - optional references for the new look; name each one's job in the instruction.
• 执行方式 - sync for a quick test, async for real edits.
• 清晰度 - 1080P default.
• 视频时长 - 3–15 seconds of output.
• 随机种子 - fixed default.

Install and first run

cd ComfyUI/custom_nodes
git clone https://github.com/htrert/ComfyUI-Tikpan-Pro

Restart (or Manager → "Tikpan"), paste your sk- key, load a short clip, write one focused edit instruction, and run at 720P first. Short clips and single-purpose instructions edit far more reliably than long videos with stacked demands.

Common issues

Where people get burned here: uploading a huge local video and watching it stall - use a hosted URL instead; and stacking multiple edits into one instruction, which invites the model to drop one of them (split into sequential edits instead). Timeouts and double-billing behave like every other video node - keep the 任务ID and use the task-query node to recover, check the log before re-running. And remember the preview gotcha: a VIDEO output that won't render in the UI usually means the file is fine on disk and your ComfyUI lacks a video-preview extension.
