A few years ago, to hardcode subtitles in a MP4 video, you first had to type what was being said, then copy and paste each subtitle into a complicated piece of software like Adobe Premiere, Final Cut Pro, or Avid. Then, you'd have to adjust and reposition each subtitle. Finally, you'd have to wait for the final video to render. This entire process used to take hours to complete. But now, with Sonix, you just need to follow these six simple steps and you'll hardcode subtitles into your MPEG-4 Video File video in minutes.
