Then you have never seen anime translations where signage in the
videos are translated. If the subtitles are off even by one frame in
such a case, you will see it, especially when the translated sign is
moving with the video, and one new subtitle event is generated for
every video frame.
You can't sync to audio when the element you are translating is in the
video itself, and not audio.
