which fonts, size, color do you use for subtitling?
also how many character per line? also considering the safe area to be kept ie. in premiere 20 % safe area.

i am adding subtitles to PAL 4:3 format material using avisynth and then converting it via procoder express to 16:0 NTSC. the subtitle lines get very wide and i need a narrow fonts.

also about font color. this is an important one, because pure white gives flicker to the subtitle.
