Summary0000744: single line subtitles not on lowest position

A single line subtitle should use the lower position instead of the top position.
(eg. the position where the second line of a double line subtitle appears).

Did not test with a final DCP yet, only with the preview window.

top line of a 2 line subtitle
bottom line of a 2 line subtitle

Steps To Reproduce

Check the preview of a single line .SRT subtitle.

top line of a 2 line subtitle
bottom line of a 2 line subtitle

wrong position of a 1 line subtitle

correct position of a 1 line subtitle

Hi, thanks for the report, do you have a reference to say which is the correct position of a 1-line .srt subtitle?

I don't have a direct reference at hand.

But being a projectionist I notice that most (if not all) DCPs, DVDs,
Blu-rays, mediaplayers, video players etc. use the lower position
for a single line subtitle.
This is probably because this way the image is obscured less.

Couldn't find any "hard evidence" after some googling .. :-)

But I verified that both VLC and MPlayer use the lower position for 1-line subtitles. And if I remember correctly the standard FFmpeg "subtitles" filter
has this behaviour.
And I found a suggestion here:

"In the case of a single-line subtitle, this should occupy the lower of the two lines, rather than the top line in order to minimise interference with the background image action."

Of course this is not a proof or a specification.
But I personally think it is the preferred behaviour!

Fair enough ;) Thanks for looking into it.
