How to Make an AI Twerk Video with VdoBloom's Twerk Video Effect
A practical walkthrough of VdoBloom's Twerk Video effect: the hip-centred WAN 2.7 keyframe, the four templates, the photo framing that actually works, and real credit costs from 10 credits per clip.
To make an AI twerk video on VdoBloom, open the Twerk Video tab, upload one photo framed from mid-thigh up, pick one of the four motion templates (Energetic, Smooth, Powerful or Rhythmic) and generate — the entry price is 10 credits, about $0.50, on Runway Gen-3 at 720p for 5 seconds. The effect adds rhythmic hip-driven dance motion to the person in your still while locking their face, clothing and proportions. If the photo is of a real person, you need that person’s consent before animating them.
How the Twerk effect is built
This is one of eleven effects on VdoBloom that run the keyframe pipeline rather than passing your photo straight to a video model. Your upload goes first to WAN 2.7 Image, which renders a 2K keyframe under a strict identity instruction: preserve face, age, skin tone, hairstyle and body proportions, no face swaps, no added people, no extra limbs or fingers, natural 35–50mm perspective. For the Twerk effect specifically, that keyframe is composed as a medium frame emphasising hips and lower torso from a tasteful angle, with a stable stance ready for rhythm and a simple studio background.
The keyframe then goes to whichever video model you picked, carrying the instruction for a rhythmic hip-driven dance move to music with studio lighting, a stable cinematic camera and a music-video look. Twerk is also one of the few effects that sets a motion mode of fast, so on PixVerse models you get noticeably more displacement per second than the Sexy Dance tab produces.
Two practical consequences. First, the tab exposes a smaller model list than the main video tabs, because the keyframe dispatcher only accepts the Runway, Kling, PixVerse, Vidu and Lightricks families. Second, the whole job is two generations chained together, so it takes longer than a plain image-to-video run — expect to wait rather than watching it appear.
The photo that works
Framing matters more here than on any other effect tab, because the keyframe is explicitly hip-centred.
- Include the hips. Mid-thigh to head, or full body. A waist-up crop gives the model nothing to animate and it will either invent a lower body or barely move.
- Stable, upright starting pose. The keyframe asks for a stance ready for rhythm. A photo already mid-motion fights that and produces jitter.
- Side or three-quarter angle beats straight-on. Hip movement reads as movement only when there is depth in the pose.
- Plain background. The keyframe prompt asks for a simple studio backdrop; a busy real-world background will warp behind the motion.
- One subject, no crop through the arms, no heavy motion blur. The identity block forbids extra people, so remove anyone else before uploading.
- 9:16 for social. Set the aspect ratio in the panel, not in post.
The four templates
Unlike most effect tabs, Twerk ships a long structured default prompt, and each template is a full rewrite of it rather than a few keywords. All four keep the identity-preservation block and the rule that only the person from the uploaded image may appear.
- Energetic — dynamic dance movement and vibrant energy, bright lighting. This is the default and the highest-motion option.
- Smooth — fluid movement and elegant flow, soft lighting. The most forgiving template on an imperfect photo.
- Powerful — strong movement, bold and commanding, dramatic lighting. Highest contrast, highest artefact risk on cluttered plates.
- Rhythmic — motion synchronised to a beat, warm fluid movement. Best choice if you plan to cut the clip to a track afterwards.
Every template has a preview video in the picker, so you can see the motion style before you spend a credit.
What it costs per model and tier
Every new account starts with 10 free credits and no card. One credit equals $0.05 at the Lite rate ($15 per month for 300 credits); annual billing and larger one-time packs lower that, and packs bought outright never expire.
| Model | Resolution / length | Credits | Lite-rate cost | Notes |
|---|---|---|---|---|
| Runway Gen-3 | 720p / 5s | 10 | $0.50 | Tab default; exactly the free signup allowance |
| Runway Gen-3 | 720p / 10s | 20 | $1.00 | Double length, same resolution |
| Runway Gen-3 | 1080p / 10s | 30 | $1.50 | Best value for a long 1080p take |
| PixVerse v3.5 | 720p / 5s | 18 | $0.90 | Cheapest PixVerse tier with the fast motion mode |
| PixVerse v4.5 | 720p / 8s | 35 | $1.75 | Full 8-second loop, popular default |
| PixVerse v5 | 1080p / 8s | 50 | $2.50 | Strongest PixVerse motion per credit at 8s |
| PixVerse v5.5 | 1080p / 10s | 70 | $3.50 | Premium tier, audio-capable |
| PixVerse v6 | 720p, per second | 9 per second | $0.45 per second | Priced per second, 1–15s; 1080p is 18 per second |
| Vidu Q3 Turbo | 720p / 8s | 28 | $1.40 | Fast, audio-capable |
| Vidu Q2 Pro | 1080p / 8s | 100 | $5.00 | Cinema tier; overkill for most social clips |
| Kling V2.5 Turbo | 5s | 40 | $2.00 | Best body coherence; no quality or ratio control |
| Kling V2.5 Turbo | 10s | 80 | $4.00 | Long take, least looping |
| LTX-2 Fast | 1080p / 6s | 20 | $1.00 | Cinematic with generated audio; 4K 6s is 77 credits |
Step by step
- Go to the Twerk Video tab.
- Upload one photo under Upload Photo. Hips visible, one person, simple background.
- Choose a template — start on Energetic, or Rhythmic if you already have a track in mind.
- Leave the model on Runway Gen-3 for the first attempt. It is 10 credits, so a failed framing test costs 50 cents rather than four dollars.
- Set duration, quality and aspect ratio. Runway Gen-3 offers 5 or 10 seconds, 720p or 1080p, and 16:9, 4:3, 1:1, 3:4 or 9:16.
- Generate. Credits are checked before the job starts, so an underfunded job is refused rather than half-charged.
- Review the motion. If the hip motion reads well but the clip is too short or too soft, re-run the same photo and template on PixVerse v5 or Kling V2.5 Turbo.
- Download. Free accounts carry a watermark; every paid plan downloads clean with commercial rights.
Editing the prompt without breaking it
The prompt box is editable and pre-filled with the full template text. Add to it, do not rewrite it. Appending a setting (in a neon-lit club, on an outdoor terrace at sunset) or a camera note (static locked-off camera, slow push-in) works reliably. Deleting the identity-preservation sentences is what causes drifted faces and extra limbs, so leave that block alone.
Requests the pipeline will resist by design: a second dancer, a costume change, or a named real celebrity. If you want a different outfit, change it first in the image editor and bring the result here.
When another tab is the better answer
Twerk is narrow on purpose. If you want a full-body expressive routine with arms rather than hip-focused motion, the Sexy Dance tab frames three-quarter to full body with a visible floor plane and does not force the fast motion mode — a genuinely different clip. Body Shake is the option for a shoulder-and-hip shimmy from an upright frame. Fashion Walk handles runway movement, and Gym covers fitness posing. All of them price identically per model, so trying a second tab only costs another generation.
On content: VdoBloom labels models by filter strictness and the flexible tier will produce dance, swimwear, fitness and fashion that mainstream tools refuse, while explicit and illegal content stays blocked at the moderation layer. The flexible-model page explains where that line is drawn, and pricing covers the plans and never-expiring credit packs.
Frequently asked questions
What is the cheapest way to make one?
Runway Gen-3 at 720p for 5 seconds, 10 credits, which the free signup allowance covers exactly — one full twerk clip without a card.
Why does my clip barely move?
Almost always framing. The keyframe stage is built around hips and lower torso, so a waist-up photo leaves nothing to drive. Re-upload a mid-thigh or full-body shot and switch to the Energetic template.
Can I make it longer than 10 seconds?
Yes, on Vidu Q3 Turbo, which supports 16-second clips (55 credits at 720p, 73 at 1080p), and on PixVerse v6, which runs 1 to 15 seconds at 9 credits per second at 720p.
Does it keep the face?
The WAN 2.7 keyframe locks face, age, skin tone, hairstyle and body proportions before any motion is applied, and it retries up to three times if that keyframe fails. Likeness holds well on sharp source photos and drifts on low-resolution or heavily filtered ones.
Is the output watermarked?
On the free tier, yes. Paid plans from $15 a month download watermark-free with commercial rights — details on the watermark-free page.
