How to make a splash in your own footage bigger without it looking added
Tell Vizard Agent which moment to amplify and how much bigger you want it. It studies the frames around the impact to find exactly when the splash starts, isolates the real droplets already in your shot, builds the bigger version out of that same water rather than generating new water, and confirms the sound has not shifted.
What is the short version?
An added splash gives itself away because its water is not your water — wrong colour, wrong light, wrong speed. Building the bigger splash out of the droplets already in the frame removes every one of those tells at once.
- Go to Vizard Agent with the clip.
- Name the moment and say how much bigger.
- Say it has to stay realistic.
What do you need before you start?
The clip and a description of the moment in the action. "When the bottle hits the bench" locates a frame far better than a timestamp does, and it also tells Vizard Agent what the splash is reacting to, which is what the timing has to be anchored on.
- The clip at its original quality.
- The moment. Described by what happens.
- How much bigger. Higher, wider, denser, more droplets.
- How realistic. Say if it must stay believable.
- Whether the sound may move. Usually it must not.
What do you type into Vizard Agent?
Say "realistic" and mean it. Asking only for bigger gets you bigger, and past a certain point bigger stops looking like water — adding the constraint keeps each round pushing the scale up rather than pushing the realism down.
Prompt
Variants worth knowing:
- "Especially when it hits." Anchors the peak.
- "Same speed as the water already there." The tell that matters most.
- "Keep it realistic." The limit on each round.
What does Vizard Agent actually do?
Here is the order Vizard Agent worked in on a real clip of a bottle striking a bench. Notice how much looking at frames happens before anything at all gets built, and pay attention to where the water for the bigger splash actually comes from.
- Checks the clip's duration and key frames.
- Extracts a series of frames around the splash.
- Studies the bottle and droplet positions with exact timestamps.
- Prepares a large frame of the splash's peak for precise positioning.
- Builds a first extra-droplet layer and assembles a test.
- Checks the result frame by frame before, during and after the moment.
- Isolates the real droplets out of the original splash.
- Builds the amplification from that same water and composites it.
- Checks the enhanced texture against the original.
- Watches it in motion and confirms the sound has not shifted.
- Synchronises the peak to the frame the bottle strikes.
- Verifies the real timecodes of when the splash actually begins.
- Studies the bottle's movement across the whole splash to anchor the effect.
- Increases the density and scale of the real droplets specifically.
Step seven is the whole technique. Droplets cut from your own footage already have the right colour, the right blur and the right light on them, so scaling and multiplying them produces more of the same water instead of a different substance sitting on top of it.
Step twelve is the timing discipline. A splash looks added when it starts a frame or two before or after the impact, and the impact frame gets confirmed from the timecodes rather than estimated — because at speed, one frame is the difference between cause and coincidence.
What does the result look like?
The same shot with a much bigger splash in it: higher, denser, with large droplets and separate drops that travel at the speed the original water travels, peaking on the frame the bottle lands and leaving the sound exactly where it was.
Nobody watching decides the water was added, because it was not.
When does this not work well?
There has to be some real water to build from. A splash that is barely visible, badly lit or motion-blurred into a smear gives nothing to isolate, and an effect built without that source material is a generated splash with all the usual tells.
- Almost no visible splash. Nothing to amplify.
- Heavy motion blur. The droplets cannot be isolated cleanly.
- Low resolution. Scaled droplets go soft.
- A moving camera. The effect has to move with it.
- Wanting a cartoon splash. Then realism is not the goal.
How do you fix a result that came back wrong?
Say what looks wrong about the water rather than asking for more of it. Vizard Agent keeps the isolated droplets and the timing, so a change to scale or density reuses the same source water instead of starting again.
- "Still not big enough." Density and scale increased, same water.
- "The droplets move too fast." Re-timed to the original speed.
- "It starts too early." Re-anchored to the impact frame.
- "It looks fake now." Pulled back to the realistic version.
How does Vizard Agent compare to doing it yourself?
The quick route is a stock splash element composited over the moment, which is fast and visibly a different piece of water. The careful route is rotoscoping droplets out of your own frames, which is slow enough that almost nobody does it.
| By hand | Vizard Agent | |
|---|---|---|
| Where the water comes from | A stock element | The droplets already in your shot |
| Timing | Placed by eye | Anchored to the impact frame |
| Speed | The element's own | Matched to the original water |
| Checking it | Watched once | Frames before, during and after |
| The sound | Often drifts | Confirmed unmoved |
Common questions
Can it use my own water? Yes. Vizard Agent isolates droplets from the shot itself.
How much bigger can it go? Until it stops looking real. Vizard Agent will say when.
Will the sound move? No. Vizard Agent checks the audio has not shifted.
Can it hit the exact frame? Yes. Vizard Agent verifies the impact from the timecodes.
Does it work for sparks or dust? Yes. Vizard Agent isolates what is there and multiplies it the same way.
What if the shot is handheld? Vizard Agent anchors the effect to the moving subject.
Can I ask for it several times bigger? Yes, and Vizard Agent reuses the same isolated droplets each round.
Will it slow the shot down? Only if you ask. Vizard Agent matches the droplet speed either way.
Can it add a sound to the impact? Yes. Say so and Vizard Agent places it on the same frame.
What about slow motion? It helps. More frames give Vizard Agent more droplets to work from.
Can I see the before and after? Yes. Ask Vizard Agent for frames from both.
Does it re-encode the whole clip? Only the affected section, unless you tell Vizard Agent otherwise.
Can it do this on generated footage? Yes, though generated water is often inconsistent to isolate.
Why not just add a stock splash? Because stock water carries its own colour, light and speed, and all three disagree with your shot at once.
