MattVidPro breaks down his full AI intro workflow: Runway + Seedance 2.5 keyframes
MattVidPro · youtube · 2026-10-09
YouTuber MattVidPro has published a complete walkthrough of how he makes his over-the-top AI-generated video intros, along with his Seedance 2.5 prompting guide (open-sourced on GitHub).
- Core trick: blending AI-generated footage into real shots seamlessly using a locked end frame, so the last frame of the AI clip matches the first frame of live footage for a smooth handoff
- Toolchain: Seedance 2.5 keyframe mode inside Runway for generation; ChatGPT to turn loose ideas into full video prompts
- Process: ideation → prompt iteration → generating multiple takes, splicing the best ones, and polishing the transition, demonstrated step by step with his "sarcophagus" intro
- The Q&A also covers Runway Agent and the Runway MCP
The video is sponsored by Runway, but the workflow is fully reproducible — useful for creators and brands making AI video intros.
