# Hop Hop Hop Dance > Replace characters in a fixed five-second cartoon dance. One image replaces foreground-right A and preserves background-left B; two required images replace A and B respectively. Local previews and phone transfer are public. Purchase video credits and submit a generation from your account. ## Current availability - Public video generation: available to signed-in users with video credits. One credit per generation. Administrator tests are a separate permission-protected mode. - Checkout: enabled. - The homepage contains sample artwork and video previews; these are examples, not results generated from your photo. - Visitors can preview photos without sending them to Kie. Sign in to buy a pack and generate. A preview alone does not charge credits. - This is an independent project, not affiliated with TikTok or the creators of the dance trend. - [Cartoon reference video](https://hophophopdance.net/videos/hop-hop-hop-dance.mp4): a fixed five-second, 720 × 1280 MP4. It does not change when photos are selected and does not demonstrate a completed personalized generation. ## Photo input - Replace A only: image 1 fully replaces the large character at the front right at the start of the clip. The original blond character B at the back left is preserved. - Replace A + B: both images are required. Image 1 maps to A and image 2 maps to B, regardless of upload order. Changing modes preserves image A; single mode never submits image B. - Accepted files: JPEG, PNG and WebP. Maximum 10 MiB per file and 50 MiB aggregate validation limit. - Use clear, well-lit faces and only photos you have permission to use. Confirm the photo consent checkbox before continuing. - Submitting a generation sends selected images and the fixed reference video to Kie. One account credit is reserved atomically with task creation. Confirmed upload or provider-generation failures return that credit; an ambiguous submission keeps it reserved pending support review. Audio processing can be retried at no additional cost. Administrator tests use the provider balance without consuming account credits. ## Phone-to-computer transfer - On desktop, scan the QR strip below the photo cards. Click it to enlarge the code or select an individual photo recipient. Choose a photo or take a selfie on the phone, then send it to the computer. - A pairing expires after 5 minutes. The phone and computer must both be able to reach this deployment; a localhost address is not reachable from another device. - Phone uploads are temporarily stored by this deployment for transfer. Stored image bytes are removed after the computer acknowledges receipt or the transfer is cancelled. - Expired transfers cannot be retrieved. Expired records are removed during subsequent handoff activity; there is no guaranteed scheduled deletion deadline while the service is idle. - Transferring a photo does not start generation or payment. ## Guides - [Hop Hop Hop dance guide](https://hophophopdance.net/#dance-guide): Understand the original movements and fixed A/B role mapping. - [Photo tips](https://hophophopdance.net/#photo-tips): Choose clear portraits and prepare your dance duo. - [Frequently asked questions](https://hophophopdance.net/#faq): Check the demo, photo privacy and current availability. ## Product and machine-readable references - [Home and photo selection](https://hophophopdance.net/#make): current interactive interface. - [Displayed packages](https://hophophopdance.net/#pricing): one-time video packs with Stripe checkout. - [Pricing facts](https://hophophopdance.net/pricing.md): shared display catalog and purchase availability. - [Capabilities and model status](https://hophophopdance.net/models.md): generation workflow and requirements. - [Complete product reference](https://hophophopdance.net/llms-full.txt): this index, pricing facts and model status in one document. - [Blog](https://hophophopdance.net/blog): articles and guides. - [Contact](https://hophophopdance.net/contact): support at support@hophophopdance.net. ## Reading these documents - These are first-party product statements, not independent reviews or guarantees.

Starting a video reserves one credit. - Packages are one-time purchases: 1, 5 or 10 account credits, with no expiry. One credit generates one 5-second, 720p video.

It is not an AI-provider catalog or an inference API specification. | Capability | Current status | | --- | --- | | Replace A only | Image 1 replaces A; original B is preserved | | Replace A + B | Both image 1 for A and image 2 for B are required | | Local photo preview and removal | Available in the current browser session | | Phone-to-computer upload | Available through a short-lived QR pairing | | Public video generation | Signed-in users with sufficient account credits | | Package checkout | Enabled | | Generation model | Kie bytedance/seedance-2-mini; API key required | | Account result | Status polling and playback/link; current task resumes in the same browser session | The A-only and A+B choices are replacement modes, not different model providers. Single, Five Pack, Ten Pack are package names, not model identifiers. Generations request 5 seconds, 9:16, 720p, generate_audio=false, with reference_image_urls and reference_video_urls together. Images define full appearances; the original video defines movement, timing, paths, occlusion, scene and its original cut around 4.4 seconds. After the cut, B is in the foreground and A in the background; identities remain fixed. The server automatically copies the original soundtrack into the generated picture and saves the finished MP4. The page offers playback and download only after this succeeds. Audio/save failures can be retried without another paid generation. Output fidelity is not guaranteed. The footer AI links open third-party AI interfaces with a suggested evaluation prompt. They do not call an AI API, send photos, automatically submit messages or make those providers part of the generation pipeline. Google AI Mode is labelled as that destination rather than as the Gemini app. Related: [Product index](https://hophophopdance.net/llms.txt) · [Display prices](https://hophophopdance.net/pricing.md) · [Photo guide](https://hophophopdance.net/#photo-tips)
