Clip Machine

Clip Machine plays videos you choose. A background loops, and when a viewer sends a gift, comments, follows, shares or likes, it cuts to the clip you bound to that trigger.

It ships with a working pack, so this guide is only about replacing it with your own.

What you need

Two kinds of video, and they follow opposite rules.

Vertical (9:16). Five videos is a real game: one idle, plus reactions for a cheap gift, a big gift, a follow and a share.

The one rule that matters

Every clip must start from the same still image. Make one picture of your scene, then feed that same picture into your video tool as the starting frame for every clip. Change only the action.

All three came from this one frame. Same cat, same cart, same lighting, so a trigger cuts cleanly instead of jumping to what looks like a different video.

Skip this and your clips will not match, whatever tool you use.

Making them on Replicate

This is exactly how the shipped pack was made. Copy it.

1. Make your reference image. Any image generator. Vertical, 9:16. This is your character and your set, so get it right before making any video.

2. Open the model. replicate.com/bytedance/seedance-2.0-fast

3. Set these inputs:

4. Build the prompt. Paste these three blocks first, every time, unchanged apart from your own character description in the first one. Each exists because leaving it out broke a clip.

Identity — stops the character changing between clips:

The character is the same [YOUR CHARACTER] in the same [YOUR SETTING].
Keep them and the background exactly as they appear in the first frame.
Do not change them, their colour, their markings or their face.

Framing — stops the model zooming, which reads on stream as the picture jumping:

CRITICAL: the camera framing must match the first frame EXACTLY for the whole clip.
Do not zoom in, do not zoom out, do not push in, do not crop tighter, do not move the
camera closer or further away. Everything must stay exactly the same SIZE and in exactly
the same position in the frame as in the first frame. Locked-off static camera, identical
shot size from first frame to last.

Lighting — stops each clip being re-lit, which steps visibly at every cut:

The lighting, exposure and colour grade must stay exactly the same as the first frame for
the entire clip, and must not be re-lit or re-graded. Same brightness, same colour
temperature, same background tone. Do not darken, do not brighten, do not add shadows,
do not change the mood or the time of day.

5. Add your action, then the ending rule. This is the only part that changes per clip.

For a reaction clip:

[YOUR ACTION, e.g. "the cat holds up a doughnut and grins"]
The entire action completes within the first 2 seconds, then holds steady and still for the
remainder. The camera never moves.
Do not use any green colors anywhere in the scene.

For an idle video — note this is the opposite instruction, and it matters:

[YOUR ACTION, e.g. "the cat tidies the counter and straightens the cups"]
The character keeps moving gently and continuously for the entire clip. It must never freeze
or hold a still pose.
The clip must loop seamlessly: it begins and ends in exactly the same neutral resting
position, so the last frame flows back into the first frame without a jump.
The camera never moves.
Do not use any green colors anywhere in the scene.

6. Run it, watch it, then do the rest. Roughly $0.28 per 4-second clip. The whole shipped pack was a few dollars. A clip that comes back wrong still costs, so check the first one before queueing eight.

Make more than one idle

A single background loop repeating gets noticed within a minute. The shipped pack uses four, shuffled: one near-static resting shot that plays most of the time, and three small bits of business.

Other tools

Any generator that accepts a starting image works, and the three prompt blocks above transfer unchanged. Runway, Kling, Pika, Luma, Hailuo and Sora all qualify.

Filming yourself also works, and the same rule applies: lock the camera on a tripod, do not change the lighting or your clothes, shoot everything in one session, and start and end each take in the same position.

Adding them to the game

In the game panel, each trigger row takes a video, an icon and a name, and you choose what fires it: a specific gift, any gift over an amount, a comment keyword, a follow, a share or a like. Up to thirty rows.

Your idle videos go in the Idle Videos field. Clear it and add your own to replace the pack.

If your videos are not vertical, set Video fit to Contain to letterbox them, or Cover to fill the frame and lose the edges.
