I'm on the fence about a few things concerning subtitles. Oh, for our non-English speaking friends, "on the fence" means I can't decide :-). I usually set up subtitles so that the name of the speaker is initial caps followed by a colon (e.g., Mary: Dialog text). Do you think it should be initial caps or all caps? (e.g., MARY: Dialog text).
I also enclose sounds in parentheses. Do you also think these should be initial caps or all caps? For example: (Sound effect) or (SOUND EFFECT).
Also, I usually italicize dialog that is coming over a PA system, a phone, a radio, etc. Do you think that the dialog for people who are present but just offscreen should also be italicized? I forgot to mention in my original post that I also italicize narrators/voiceovers.
I'm interested in all opinions and would like as many replies as possible so I can get a good idea of what the majority of people would prefer.
