Thanks.
I have subtitles I made in DVD architect.
Lately I have been importing scripts from word, synchronising with caption assistant, converting to titles/text, then rendering to MP4 and that is working (so, open captions), so I could do that.
However I’m still not understanding how I give someone a clip along with separate captions which they can upload for people to turn on and off. Do I need to ask the client what platform they will play it on? I suspect it will be played on you-tube so I thought it would be simple to export the subtitles from architect to Vegas and then run the script to “export captions for you tube”. Would that work? And if so would I then have to render the footage to something other than MP4?
Hope that makes sense.
