Hi,
I had a similar problem with the vertical position of the subtitles (see "Margin settings for subtitles not working?", it's a few posts below yours).
There is a bug and the margin settings don't work, so rvm gave me a link for an unstable version (not offially released) in which the problem is fixed for the vertical margin (left and right still don't work).
With this version, when I set vertical margin to zero and of course have the black bars added, the subtitles appear at the bottom of the screen:
- SMPlayer_2.jpg (57.8 KiB) Viewed 3669 times
So, there is no need for negative values.
What would be great though, is if we could zoom out and move the picture up (and down) without affecting the size and position of the subtitles (I've found only one player that can do this, but I really prefer to use SMPlayer for everything).
This way, we could make enough space to fit the subtitles under the picture even for a movie that is 16:9. This would be very helpfull for videos that have subtitles burned-in and also when you need to have two subtitle languages at the same time, but in order not to cover half of the image with four lines of text, you could have the second language below the image on black space.
Believe me, this is extremely useful for classes and seminars where big screens are used, so there is no problem to zoom out the image a little, just to fit subtitles below.
But in order for this to work, the subtitles' size and position sould not be affected by the zoom function.
It would be really great to consider this function (all teachers and lecturers will love you...).
Best regards,
