视频｜Kling Motion Control 动作控制

This is the pack's most distinctive Kling node, and the most useful for anyone doing character/IP work: it takes a reference video's motion and transplants it onto your own character image. You feed it a static 角色图像 (the character who should move) plus a 动作参考视频URL (the moves to copy), and it returns a video of your character performing those moves while keeping the character's identity - same face, same outfit, same look. This is the "AI digital human" and "TikTok remix" trick, and it's the kind of thing Kling does better than almost anyone.

The mechanism is worth understanding because it's not magic: this is motion transfer, not full re-generation. The reference video supplies the motion; the character image supplies the identity. It works best with full-body motion on a clean background - a cluttered action video gives the motion extractor noise to chew on. And it inherits every limit of the underlying Kling v2.6/v3 model, which the node exposes through the 模型版本与模式 dropdown (std 720P vs pro 1080P).

How it works

The reference video needs to be a public URL (动作参考视频URL); for a local file there's 本地动作视频路径, which the node uploads to Tikpan first - for big videos, a URL beats an upload every time. The 动作描述 field is a free-text supplement ("keep the expression natural, full-body movement") that refines the transfer. 视频时长 defaults to auto, following the reference video's length, and 画面比例 defaults to auto too - both make sense when the source video defines the output.

Outputs are the standard five: 🎬_视频输出 (VIDEO), 📁_本地保存路径, 🆔_任务ID, 🔗_视频云端直链, 📄_完整日志.

The inputs that matter

• 角色图像 - your character, static, ideally full-body and well-lit.
• 动作参考视频URL - the moves to copy; clean, single-subject footage transfers best.
• 模型版本与模式 - kling-v2-6｜std｜720P by default; pro for 1080P.
• 动作描述 - nudge the transfer: keep the face natural, avoid artifacts, etc.
• 本地动作视频路径 - only if your source is local and under the upload cap.

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 the character image, paste the reference URL, run at the default settings. Start with a short, single-action reference clip - motion transfer is easier to judge and cheaper to iterate on when the source motion is one clean action rather than ten seconds of everything.

Common issues

The pack-wide staples (401/402/429, timeouts - raise 最长等待秒数 for pro mode or long references - and the charge-with-no-file case, always check 完整日志). Motion-control-specific: the reference video being too busy is the top quality killer (motion extraction degrades on cuts and cluttered scenes), and a character image that isn't full-body will fight the reference motion. Local video uploads are the flakiest path - put the file on a public URL instead if you can.
