Capabilities

Beyond text-to-video

Image to video

Upload any still image and animate it. Send images directly from the image generator gallery to skip the upload step. Works on Kling, Luma, and Veo 3.

Video extension

Take any 5-10 second clip and extend it. Server-side FFmpeg extracts the last frame and feeds it back into Kling or Luma image-to-video with a continuation prompt, chaining clips into longer cuts.

Multi-clip stitching

Combine several generated clips into one video with FFmpeg-powered stitching. Add transitions, voiceover, and captions to assemble finished ads or VSL sequences.

Voice Lab and audio

Generate voiceovers with ElevenLabs and OpenAI TTS, then mix them onto any video. Veo 3 also generates synchronized native audio without an external voice step.

VSL Studio

A 17-prompt pipeline for long-form video sales letters: hook, story, claim, proof, offer, close. Built for marketers running paid traffic to long-form video.

AI script generation

GPT-4o writes scripts and motion prompts from rough ideas. Use the Magic Campaign generator to scaffold an entire ad set including hooks, scripts, and shot lists.
