What are the best practices for handling input (text + images) and output (video) in a PHP video generator?

When handling input (text + images) and output (video) in a PHP video generator, it is important to properly sanitize and validate all input data to prevent security vulnerabilities. Additionally, it is crucial to efficiently handle image processing and video rendering to optimize performance and output quality. Utilizing libraries such as FFmpeg for video generation can simplify the process and enhance functionality. 

// Example of handling input (text + images) and output (video) in a PHP video generator

// Sanitize and validate input data
$text = filter_var($_POST['text'], FILTER_SANITIZE_STRING);
$image = $_FILES['image']['tmp_name'];

// Image processing
$im = imagecreatefromjpeg($image);
// Do image processing here

// Video rendering using FFmpeg
$video = shell_exec('ffmpeg -loop 1 -i image.jpg -c:v libx264 -t 30 -pix_fmt yuv420p output.mp4');

// Output video
header('Content-Type: video/mp4');
readfile('output.mp4');
