# Bicep Heart AI > Turn one portrait into a playful seven-second bicep heart video with music. Preview your photo, sign in, use one credit and download the finished clip. ## 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. - [Bicep heart reference video](https://bicepheartai.net/videos/bicep-heart.mp4): a supplied seven-second, 576 × 1024 MP4. It does not change when photos are selected and does not demonstrate a completed personalized generation. ## Photo input - Upload one clear portrait of one person. The image guides appearance, hair, clothing and body proportions; the fixed video guides the bicep heart gesture, timing, lighting and camera. - 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 - [How it works](https://bicepheartai.net/#how-it-works): Upload one portrait, generate and share. - [Photo tips](https://bicepheartai.net/blog/bicep-heart-photo-guide): Choose a clear portrait for your bicep heart. - [Frequently asked questions](https://bicepheartai.net/#faq): Photos, credits and your finished video. ## Product and machine-readable references - [Home and photo selection](https://bicepheartai.net/#make): current interactive interface. - [Displayed packages](https://bicepheartai.net/#pricing): one-time video packs with Stripe checkout. - [Pricing facts](https://bicepheartai.net/pricing.md): shared display catalog and purchase availability. - [Capabilities and model status](https://bicepheartai.net/models.md): generation workflow and requirements. - [Complete product reference](https://bicepheartai.net/llms-full.txt): this index, pricing facts and model status in one document. - [Blog](https://bicepheartai.net/blog): articles and guides. - [Contact](https://bicepheartai.net/contact): support at support@bicepheartai.net. ## Reading these documents - These are first-party product statements, not independent reviews or guarantees.

It is not an AI-provider catalog or an inference API specification. | Capability | Current status | | --- | --- | | Single portrait | One image defines the person in the bicep heart clip | | 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 product has one portrait input and one fixed bicep heart template. Single, Five Pack, Ten Pack are package names, not model identifiers. Generations request 7 seconds, 9:16, 720p, generate_audio=false, with one reference_image_url in reference_image_urls and the fixed reference_video_urls together. The portrait defines appearance. The clip defines a continuous shot: step back, flex one arm, form a small heart against the bicep and hold it with a smile. The prompt excludes the source I / YOU overlay. 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://bicepheartai.net/llms.txt) · [Display prices](https://bicepheartai.net/pricing.md) · [Photo guide](https://bicepheartai.net/blog/bicep-heart-photo-guide)
