Need	Model	Why
Default / Quick preview	veo3fast	Best balance: speed, quality, cost
Talking head / lip-sync	grok, kling26	Grok: best lip-sync; Kling26: best motion
High quality cinematic	sora2pro, veo3	Premium quality, synced audio
Image animation	kling, gen45	Strong image-to-video
Budget production	rayflash, seedance	Cheapest per-second
Longest duration (15s)	grok, kling	Only models supporting 15s
Real-world physics	hailuo, hailuo23	Physics simulation, VFX

# Step 1 — Age-progress reference photo (if needed)
node scripts/generate-image.js "A 26-year-old professional in studio" --model nanapro --image ref.png

# Step 2 — Generate video with Kling v2.6 (best talking-head i2v)
node scripts/generate-video.js "Person looking directly into camera, speaking confidently" --model kling26 --image aged.jpg --duration 10

# Step 3 — Generate speech
node scripts/generate-voice.js "[script]" --model mm28turbo

# Step 4 — Merge video + speech
node scripts/generate-edit-video.js --model avmerge --video clip.mp4 --audio speech.mp3

import Replicate from "replicate";

    prompt: "A person walking through a futuristic city at sunset, cinematic lighting",
    duration: 5, // seconds
  },

Element	Good Example	Avoid
Camera motion	"slow dolly forward", "tracking shot"	"camera moves"
Lighting	"golden hour", "dramatic side lighting"	"good lighting"
Style	"cinematic 4K", "documentary style"	"nice video"
Subject	"a person with short brown hair"	"someone"
Action	"walking slowly through", "gesturing while talking"	"doing something"

// 1. Generate video (no audio)
const video = await replicate.run("kwaivgi/kling-v3-video", {
  input: { prompt: "...", duration: 5 },
});

// 2. Generate narration via TTS
const audio = await replicate.run("minimax/speech-2.8-turbo", {
  input: { text: "Narration text", voice: "Wise_Woman" },
});

// 3. Combine with ffmpeg
// ffmpeg -i video.mp4 -i audio.mp3 -c:v copy -c:a aac output.mp4

import { writeFileSync } from "fs";

const response = await fetch(output);
const buffer = await response.arrayBuffer();
writeFileSync("output.mp4", Buffer.from(buffer));

# Check video properties with ffprobe
ffprobe -v quiet -print_format json -show_format -show_streams output.mp4

Error	Cause	Solution
Generation timeout	Complex prompt	Simplify, reduce duration
NSFW rejection	Content policy	Adjust prompt
Low quality output	Vague prompt	Add specific details
Audio desync	Wrong model	Use lip-sync model
