To make an AI pool jump video, open the Pool Jump effect tab on VdoBloom, upload one photo of the person, tick the consent box, pick the Summer Dive, Dramatic or Playful template, and generate — the cheapest run is 10 credits (about $0.50) on Runway Gen-3 at 720p for 5 seconds, and signup gives you 10 free credits without a card. No pool, no swimming, no second take required.

What the pool jump effect actually does

Pool Jump takes one still photo and animates the person in it leaping into water — the launch, the arc, the splash. The tab’s own description is blunt about the job: upload a photo and the AI animates the person diving into a pool. The default prompt behind it reads: pool jump dive, splash into water, dynamic movement, summer vibes, cinematic.

Here is the part most guides skip. This is the hardest class of photo-motion effect there is, because the model has to invent three things at once: a full-body trajectory that was never in the frame, physically plausible water, and a splash that lands where the body lands. Compare that to a wink or a mirror selfie, where the model only nudges what it can already see. Expect to burn two or three cheap attempts before you get a keeper, and budget accordingly — that is why the 10-credit 720p test run matters more here than on any other effect.

If the photo is of a real person other than yourself, you need that person’s consent before you upload and animate it. The upload step carries a consent checkbox and generation is blocked until you confirm.

The photo that gives you the best odds

Full body, standing, feet visible. The model has to animate a jump. If the legs are cropped out, it has to invent them, and invented legs are where these clips fail.
Already poolside or near water. A photo taken on a pool deck, a jetty or a beach gives the model the environment for free. A photo in an office is asking for two miracles instead of one.
Bright daylight. Water reads as water when it has highlights. Dim indoor light produces grey sludge.
Side or three-quarter angle. A jump reads as motion from the side. Straight-on frontal shots flatten the arc.
Clear space in front of the subject. The body needs somewhere to travel. A wall right behind them fights the animation.

The three templates

Template	What it is for	The prompt it loads
Summer Dive	Fun, bright, straightforward summer jump	pool jump dive, splash into water, dynamic movement, summer vibes, cinematic
Dramatic	Slow-motion dive with a cinematic splash	dramatic pool dive, slow motion splash, cinematic water effect, dynamic lighting
Playful	Cannonball energy, joyful and messy	playful pool jump, cannonball splash, joyful movement, bright summer lighting, cinematic

Dramatic is the most forgiving of the three. Slow motion gives the model fewer pixels of change per frame to get wrong, so limbs hold together better and the water has time to look like water. Playful is the hardest, because a cannonball demands a tucked body pose the source photo almost certainly does not contain. Start with Dramatic, move to Summer Dive once you know the photo works.

What it costs

The effect adds no surcharge — you pay the credit cost of whichever image-to-video model you pick. Credits convert at the Lite rate of $15 for 300 credits, so one credit is $0.05.

Model	Resolution & length	Credits	Dollar cost	Best for
Runway Gen-3	720p, 5s	10	$0.50	Cheap test runs — start here
Runway Gen-3	1080p, 5s	20	$1.00	The final keeper
Runway Gen-3	720p, 10s	20	$1.00	Approach, jump and splash in one clip
Runway Gen-3	1080p, 10s	30	$1.50	Full sequence at delivery quality
Vidu Q1	1080p, 5s	25	$1.25	Smooth, professional body motion
PixVerse v4.5	1080p, 5s	30	$1.50	Punchier splash and water styling
PixVerse v4.5	1080p, 8s	50	$2.50	Longer arc before the water
Kling V2.5 Turbo	5s	40	$2.00	Fast turnaround, strict content filter

A realistic budget for one publishable pool jump is 40 to 60 credits — two or three 720p tests plus one 1080p final. See /pricing/ for plans and the one-time packs that start at $2.49 for 75 credits and never expire. Paid plans download watermark-free with commercial rights.

The exact steps

Open /dashboard/video-creation/pool-jump/.
Upload one photo under Upload Photo.
Tick the consent checkbox for the person in the image.
Select a template — Dramatic for the best first odds.
Edit the prompt to name the setting. Adding rectangular blue swimming pool, tiled deck, bright afternoon sun gives the model a target instead of a guess.
Set the model to Runway Gen-3, 720p, 5 seconds, 9:16.
Generate. Your credit balance is checked before the job is queued.
If the body holds together, re-run the same prompt at 1080p for the version you publish.

Prompting it well

Describe the water, not just the jump. Splash size, water colour, whether the surface is still or rippling — those details are what stop the model from rendering a vague white blur. Then describe the body: arms raised, knees tucked, arched dive. A jump prompt that does not specify a body shape leaves the single most failure-prone decision to chance.

Add the identity guard the platform’s own effect prompts use — preserve facial features, hairstyle and outfit exactly — because fast full-body motion is exactly where faces drift. And keep the clip short. Five seconds is enough for a jump and a splash; ten seconds gives the model room to lose the person underwater and bring back somebody else.

When to pick a different effect

If you want poolside atmosphere rather than a dive, the Bikini tab has a Pool environment preset that produces a poolside scene with water reflections and deck tiles without any jump physics at all — far higher hit rate. If you want motion but not aerial motion, Catwalk Turn or a simple image-to-video run with a camera-move prompt will be more reliable. Pool Jump earns its credits when the leap is the point of the video.

A worked example

Source: a full-body vertical photo of someone standing on a pool deck in swimwear, taken in afternoon sun. Run one is the Dramatic template with the prompt edited to read: dramatic pool dive, subject leaps forward with arms extended into a clear blue pool, slow motion splash, sunlit water, preserve facial features and hairstyle exactly, cinematic. Runway Gen-3, 720p, 5s, 9:16 — 10 credits. The first attempt lands the arc but thins the splash, so the prompt gains large splash with visible spray and droplets and re-runs for another 10. That one works. Final pass at 1080p, 5s for 20 credits. Total: 40 credits, $2.00.

New accounts can cover that first 720p attempt with the 10 free signup credits — details at /free-ai-video-generator/ — and the watermark rules for each tier are at /ai-video-generator-no-watermark/.

Frequently asked questions

Do I need a photo taken at a pool?

No, but it helps enormously. A poolside source photo means the model only has to invent the jump, not the entire environment, and your hit rate roughly doubles.

How many photos does the Pool Jump effect take?

One. It is a single-image effect tab.

What is the cheapest pool jump video I can generate?

10 credits, about $0.50, using Runway Gen-3 at 720p for 5 seconds.

Why do the arms and legs sometimes come out wrong?

Because a jump is full-body motion the source photo never showed. Use a full-body photo with visible feet, pick the Dramatic slow-motion template, and name the body position in the prompt.

Can I make a pool jump video of someone else?

Only with that person’s consent, which you must confirm on the upload step before the effect will run.

Should I generate 5 seconds or 10?

Five. Ten seconds costs more and gives the model extra frames in which the subject can drift away from the person in your photo.
