+# FFMPEG Worker
+
+For faster video en/transcoding there is a php script called `/tools/ffmpeg_worker.php` which is a CLI application looping every second, checking the REDIS Queue for encoding tasks.
+
+This way the rendering queue is detached from php-fpm since PHP can't have threaded workloads and it will make sure a encoding task like resizing of a video won't block the rest of the site from functioning.
+
+For the FFMPEG Worker to be enabled, the config option `REDIS_SERVER` must be set to the IP Address of a redis server.
