Example use cases
Product showcase morphing for marketing
“Create a video that begins with our product's original packaging design and transforms into the new redesigned version, showing the evolution with smooth transitions and lighting changes in between. Use a professional, modern aesthetic.”
Before-and-after transformation video
“Generate a video starting from this before photo of a room renovation (https://example.com/before-room.jpg) and ending with the after photo (https://example.com/after-room.jpg), animating the transformation process with construction and design elements flowing between the two states.”
Story scene transition animation
“Make a video that transitions from a character standing in a dark forest at night into the same character in a bright meadow at dawn, with the narrative of them walking through and discovering hope. Include warm lighting shifts and nature elements.”
Technical details
Endpoint
POSThttps://api.hypercli.com/api/x402/flow/first-last-frame-videoWhen to prefer
Use this endpoint when you need to generate a video with explicit control over both the opening and closing frames — ideal for cinematic transitions, morphing between two specific images, or storytelling where the start and end visual states are known. Prefer over text-to-video when you have concrete reference images for first and last frames, and over image-to-video when you also want to constrain the ending frame.
Side effects
- Invalid or inaccessible start/end image URLs return an error
- Missing required prompt field causes validation failure
- Payment failure via x402 prevents job from starting
- Unsupported image dimensions may cause generation errors
- Job may time out for very complex renders; check status URL
- notify_url webhook may fail if the target URL is unreachable
