Alibaba Happyhorse 1.0 Video Edit (Official Edition)

HappyHorse 1.0's video-edit node, official edition, and the most fully-featured video editor in this pack. Give it a video and an instruction - "change the style," "replace that object," "re-time this scene" - and it rewrites the footage. What sets it apart: an audio_setting control that can preserve the source clip's original sound, plus optional reference images so you can steer the edit with a look.

The audio option is the sleeper feature. audio_setting defaults to auto (the model decides), but set it to origin and the edited video keeps the input's original audio track. That's a genuinely useful capability - most hosted video-edit APIs silently drop or regenerate sound, and "keep my dialogue" is exactly the constraint that makes restyle jobs usable instead of novelty. If you're editing talking-head footage or anything with meaningful audio, this node is worth trying for that toggle alone.

How it works

BizyTRD cloud wrapper. media (required, a VIDEO) and prompt (required) go up, an edited VIDEO comes back. reference_images is an autogrowing input - drop in stills to steer character, palette, or composition, same numbered-order logic as the HappyHorse R2V node. Then resolution (720P/1080P, default 1080P), audio_setting (auto/origin), seed, and watermark (default on). api_config overrides endpoint/key per request; skip_error outputs a placeholder instead of aborting the workflow.

Inputs and outputs

• media (required, VIDEO) - the footage to edit.
• prompt (required, multiline) - the edit intent.
• Optional: reference_images, resolution, audio_setting, seed, watermark, api_config, skip_error.
• Outputs: video (VIDEO), request_id, urls.

Common issues

Start short and low-res: video editing is the most expensive thing in the HappyHorse family, and a long 1080P source is the fastest way to a large bill. If you want your dialogue intact, audio_setting must be origin - auto won't promise it. The watermark defaults on, and the media input expects an actual video tensor, so wire it from a video source node rather than a stack of frames. Then the pack standard: missing button (pip show bizyair-cloudberry), cloud errors in the console, metered pricing.
