What are the potential pitfalls or challenges in creating a video generator with PHP?

One potential challenge in creating a video generator with PHP is handling large video files efficiently. To address this, you can use libraries like FFmpeg to manipulate and process video files in a more optimized way. Additionally, ensuring that the server has enough resources to handle video processing tasks is crucial for smooth operation.

// Example code using FFmpeg library to process video files
$ffmpeg = FFMpeg\FFMpeg::create();
$video = $ffmpeg->open('path/to/video.mp4');

// Manipulate the video file as needed
$video->filters()->resize(new FFMpeg\Coordinate\Dimension(320, 240))->synchronize();
$video->frame(FFMpeg\Coordinate\TimeCode::fromSeconds(10))->save('path/to/output.jpg');
