Ultra-realistic AI video creation workflow (GPT-6 Astra + Seedance)

Step 1: Steal the structure, not the pixels. Capture 3-5 scenes from hotels and river views, pull character inspiration from Pinterest and real vlogs. Step 2: Analyze the reference with Gemini. Send Gemini videos, audio, keyframes; get a shot-by-shot breakdown and turn it into instructions. Step 3: Swap the world, keep the bones. Change character and environment until it feels original. Step 4: Build reference images first. Create a character sheet, one image per location in the same mood, plus the exact start frame for the video. Use Nano Banana Pro. Step 5: One 30-second video run, not ten 3-second clips. Send the full timestamped script to Seedance 2.5 via API as ONE generation. Use start frame as anchor, one action per beat, describe camera and audio concretely, lock identity at the end. Step 6: Revise like a director. Regenerate only scenes that need changes as short clips from their own start frames, then cut into the master with ffmpeg. Change one variable at a time. Step 7: Finish like normal footage. Assemble final cut with ffmpeg, add ambient music from a free library. Rules: reference structure is the asset; iterate on images, commit on video; one action per timestamped beat; lock identity explicitly; fix failed shots by changing one variable; last 10% is boring editing.
