Subtitling has three components:
-    Source script with time code:  Since usually it is a movie, the source script is either given by the client (find out) or if they dont, we have to transcribe it. This means the client has to first pay us for Transcription (hearing the voice in the movie and writing it down in the same language and time code is denoted as 00:00:00 for hours, mins, seconds. The time code means exactly when that dialogue happens from the beginning of the movie).  The charges are per minute (charges depend on the language used in the movie) and one minute has about 120 words (so you can estimate word count according to the length of the movie).  Usually this transcription (script) is first sent to client for approval so they can check it themselves first.

-    Translation: Script is then sent for translation with clear instruction to the translator to make very small sentences and phrases explaining to the translator that it is for subtitling.  Usually the script is sent along with the time code so that the translator gives us the translation that can be read in as many seconds as indicated by the time code. Translation is the second component of the cost that the client has to pay.

-    Integration: The translated text given by the translator is then integrated with the movie according to the time code so that the subtitle appears exactly when the dialogue is being said.  Integration is the third component of the cost that the client has to pay.  Usually there are 20 subtitles in a minute and an Integration fee is charged for each subtitle at US$ 2 or AED 10.
