Along with usual operations by resizing and converting videos transcoder can do the following:
- conversion queue - waiting for video conversion is minimal, videos are converting every minute
- remote conversion - videos can be converted on any number of remote servers, so main site is not overloaded with conversion and videos are processed as soon as possible
- automatic detection of fully black and white video thumbnails - videos usually begin with black or white screen which fades out after 1-3 seconds, this situation is detected and video image is taken after some image appears
- automatic video aspect ratio detection
- moving meta information to the beginning of mp4 file - so video begins to play as soon as possible
- 3rd-party modules can add custom filters for video processing
