I'm making subtitles to my short film(silent) and I need two subtitle streams, one for Finnish and one for English. I thought that the easiest way is to make Finnish one first (CC1 stream) and then just duplicate it, select it, go to captions panel, change stream to CC2 and type english subtitles for this new stream. This way I could avoid the worst part of making subtitles: typing(or copying) all the timecodes(all over again). On a captions panel, you should be able to change captions stream, but my options are greyed out. Is there a reason for this? Or is there another way to do this?
I hope there is a way out. Any help is appreciated. Thanks.
