hi saul!
i am not sure if i understand your posting in the right way. what do you refer as “background”?
if you would like to have a preset for eg italic subtitles and normal ones, this is unfortunately NOT possible right now to my knowledge :(. why, honestly, i don’t know. either bm doesn’t understand the need for it, or they simply have other priorities (eg. cut), which are NOT mine.
as only one track style is available per track and only one subtitle track can be viewed at the same time, there is no workaround i can think of possible :(. bm has to fix this.
even if this is fixed, there still is the (theoretically minor) aesthetic problem left wich is for a lot of my customers a no go: the missing OUTLINE option. only thing available: STROKE. but the thinnest possible black stroke option makes the font unusably thin!!! (and no stroke and no outline is a reading problem towards bright backgrounds)
i do complain about this since the subtitle tool was integrated (back in v15 i think), but till now, no comment, no update.
so i guess we are forced to use belle-nuit till the end of our days. this fancy little free tool which ONE suisse editor programmed years ago, but unfortunately doesn’t update anymore. the con: it is rather complicated and time consuming.
sorry for hijacking this, but is this your problem as well?
