// AI-generated React chatbot widget
import React, { useState } from "react";

export default function ChatBot() {
  const [messages, setMessages] = useState([]);
  const [input, setInput] = useState("");

  const handleSend = () => {
    if (!input) return;
    setMessages([...messages, { sender: "user", text: input }]);

    // Mock AI response
    setMessages((prev) => [
      ...prev,
      { sender: "ai", text: "This is an AI-powered response 🚀" }
    ]);
    setInput("");
  };

  return (
  <div style={{ border: "1px solid #ccc", borderRadius: "8px", padding: "10px" }}>
    <h3>AI ChatBot</h3>
    <div style={{ height: "200px", overflowY: "auto", marginBottom: "10px", padding: "5px" }}>
      {messages.map((msg, index) => (
        <p key={index} style={{ color: msg.sender === "AI" ? "blue" : "black" }}>
          <strong>{msg.sender}:</strong> {msg.text}
        </p>
      ))}
    </div>
    <input
      type="text"
      value={input}
      onChange={(e) => setInput(e.target.value)}
      placeholder="Type a message"
      style={{ width: "80%", padding: "5px" }}
    />
    <button onClick={handleSend} style={{ marginLeft: "5px", padding: "5px" }}>
      Send
    </button>
  </div>
  );
}

From Text to Cinema: How AI Video Generators Are Changing Content Creation in 2025

By LK-TECH Academy  |  September 9, 2025  |  ~8–12 min read

In 2025, turning a script into a short film no longer needs production crews, bulky cameras, or expensive studios. Modern text-to-video systems combine large multimodal models, motion synthesis, and neural rendering to convert prompts into moving images — often in minutes. This post explains the current ecosystem, when to use which tool, and provides copy-paste code examples so you can build a simple text→video pipeline today.

Why text-to-video matters in 2025

• Democratization: Creators can produce high-quality visual stories without advanced equipment.
• Speed: Iterations that used to take days are now possible in minutes.
• New formats: Short ads, explainer videos, and social clips become cheaper and highly personalized.

Landscape & popular tools (brief)

There are two main families of text→video approaches in 2025:

1. Model-first generators (end-to-end): large multimodal models that produce motion directly from text prompts (examples: Sora-style, Gen-Video models).
2. Composable pipelines: text → storyboard → image frames → temporal smoothing & upscaling (examples: VDM-based + diffusion frame models + neural interpolation + upscalers).

Popular commercial and research names you may hear: Runway (Gen-3/Gen-4 video), Pika, OpenAI Sora-family, and various open-source efforts (e.g., Live-Frame, VideoFusion, Tune-A-Video derivatives). For production work, teams often combine a generative core with post-processing (denoising, color grading, frame interpolation).

{
  "pipeline": [
    "prompt -> storyboard (keyframes, shot-list)",
    "keyframes -> frame generation (diffusion / video LDM)",
    "temporal smoothing -> frame interpolation",
    "super-resolution -> color grade -> export"
  ],
  "components": ["prompt-engine", "txt2img/vid", "frame-interpolator", "upscaler"]
}

A minimal text→video pipeline (working scaffold)

The following scaffold is intentionally lightweight: use a text→image model to generate a sequence of keyframes from a storyboard and then interpolate them into a short motion clip. Swap in your provider's API (commercial or local). This example uses Python + FFmpeg (FFmpeg must be installed on the host).

# Install required Python packages (example)
pip install requests pillow numpy tqdm
# ffmpeg must be installed separately (apt, brew, or windows installer)

# text2video_scaffold.py
import os, time, json, requests
from PIL import Image
from io import BytesIO
import numpy as np
from tqdm import tqdm
import subprocess

# CONFIG: replace with your image API or local model endpoint
IMG_API_URL = "https://api.example.com/v1/generate-image"
API_KEY = os.getenv("IMG_API_KEY", "")

def generate_image(prompt: str, seed: int = None) -> Image.Image:
    """
    Synchronous example using a placeholder HTTP image generation API.
    Replace with your provider (Runway/Stable Diffusion/Local).
    """
    payload = {"prompt": prompt, "width": 512, "height": 512, "seed": seed}
    headers = {"Authorization": f"Bearer {API_KEY}"}
    r = requests.post(IMG_API_URL, json=payload, headers=headers, timeout=60)
    r.raise_for_status()
    data = r.content
    return Image.open(BytesIO(data)).convert("RGB")

def save_frames(keyframes, out_dir="out_frames"):
    os.makedirs(out_dir, exist_ok=True)
    for i, img in enumerate(keyframes):
        img.save(os.path.join(out_dir, f"frame_{i:03d}.png"), optimize=True)
    return out_dir

def frames_to_video(frames_dir, out_file="out_video.mp4", fps=12):
    """
    Use ffmpeg to convert frames to a video. Adjust FPS and encoding as needed.
    """
    cmd = [
      "ffmpeg", "-y", "-framerate", str(fps),
      "-i", os.path.join(frames_dir, "frame_%03d.png"),
      "-c:v", "libx264", "-pix_fmt", "yuv420p", out_file
    ]
    subprocess.check_call(cmd)
    return out_file

if __name__ == '__main__':
    storyboard = [
      "A wide cinematic shot of a futuristic city at dusk, neon reflections, cinematic lighting",
      "Close-up of a robotic hand reaching for a holographic screen",
      "Drone shot rising above the city revealing a glowing skyline, gentle camera move"
    ]
    keyframes = []
    for i, prompt in enumerate(storyboard):
        print(f"Generating keyframe {i+1}/{len(storyboard)}")
        img = generate_image(prompt, seed=1000+i)
        keyframes.append(img)
    frames_dir = save_frames(keyframes)
    video = frames_to_video(frames_dir, out_file="text_to_cinema_demo.mp4", fps=6)
    print("Video saved to", video)

Notes:

• This scaffold uses a keyframe approach — generate a small set of frames that capture major beats, then interpolate to add motion.
• Frame interpolation (e.g., RIFE, DAIN) or motion synthesis can produce smooth in-between frames; add them after keyframe generation.
• For higher quality, produce larger frames (1024×1024+), then use a super-resolution model.

Prompting, storyboarding & best practices

• Shot-level prompts: write prompts like a director (angle, lens, mood, color, time-of-day).
• Consistency: reuse profile tokens for characters (e.g., "John_Doe_character: description") to keep visual continuity across frames.
• Motion cues: include verbs and motion descriptions (pan, dolly, slow zoom) to help implicit motion models.
• Seed control: fix seeds to reproduce frames and iterate predictable edits.

Optimization, compute & cost considerations

Text→video is compute-heavy. To reduce cost:

• Generate low-res keyframes, refine only the best scenes at high resolution.
• Use a draft→refine strategy: a small fast model drafts frames; a stronger model upscales & enhances selected frames.
• Leverage cloud spot instances or GPU rental for heavy rendering jobs (e.g., 8–24 hour batches).

Ethics, copyright & responsible use

• Respect copyright: don't produce or monetize outputs that directly copy copyrighted footage or music without rights.
• Disclose AI generation when content might mislead (deepfakes, impersonation).
• Use opt-out / watermark guidance as required by regional law or platform policy.

# Example: interpolate using RIFE (if installed)
rife-ncnn -i out_frames/frame_%03d.png -o out_frames_interp -s 2
# This will double the frame count by interpolating between frames

Wrap-up

Text-to-video in 2025 is a practical reality for creators. Start with short, focused clips (10–30s), iterate quickly with low-res drafts, and refine top shots at high resolution. Combine scripted storyboards, controlled prompting, and smart interpolation for the best results.
