AI Image & Video Webapp

I am building a browser-based platform, similar in spirit to GROK AI, that lets users create both still images and full-motion videos with generative AI. The workflow must feel seamless: type a prompt, receive an AI-generated image, extend that into an animated sequence, then publish.

Core functionality
• AI generation for images and videos from user prompts.
• Aspect-ratio presets 16:9 and 9:16, locked end-to-end so the output is ready for web, social and mobile screens.
• Quality presets HD and true 4K.
• One-click export to MP4 (AVI or MOV can be added later, but MP4 support is mandatory).

Deliverables
1. A responsive web app (frontend + backend) running on my cloud account.
2. An admin dashboard to monitor jobs and tweak model parameters.
3. Source code with install and build instructions.
4. Short demo video proving image generation, video generation, and MP4 export in both aspect ratios.

More details will be provided.

I’m specifically looking for someone who has already shipped AI-driven media tools or similar SaaS products and can point me to live examples. If you have that background, let’s talk about timelines and model choices right away.
