Hi,

Can you make an option in the program to offset subtitle vertical position in mkv file?
I am asking you that because if I compare the subtitle position in the DVD and the subtitle position in the mkv file obtained in makemkv the subtitle resulted in the mkv file is always lower than in DVD, sometimes it gets out of the screen (on the bottom).
If the DVD fps is 25, the vertical position differs a little bit, but if the DVD fps is 23.976 (authorized with ifoedit), the vertical position differs by aprox. 84 pixels! (I used DVDSubEdit to upper the original DVD subtitle in order to makemkv to put it in the proper place in the bottom, otherwise it gets out of the screen on the bottom).
I do not know if I made myself understood, if not I will come with screenshots.

If you are using the same software to play the MKV file as the DVD, the positioning should be identical - the data being displayed is the same.

DVD subtitles are images, not text.

I did not compare only on computer, using windows media player, but also on a standalone bluray player. The subtitles are placed on different positions comparing the original DVD and the mkv file obtained in makemkv.

After a lot of brainstorming and a little bit of reverse engineering I discovered what the issue was.
I used to author the DVD using the program called Ifoedit.
The reason I used it is because is one of the few programs that can be used to mux a mpv (with 23.976 FPS) with a ac3 and a sup file (obtained from a srt by using txt2sup). DVDLab Pro cannot do that without pulldown.
The DVD is authored without errors (only the subtitle pallete is wrong but I can modify it later using DVDSubEdit).
The issue is that in the DVD files headers it is written the wrong information.
Instead of writing PAL parameters (25 FPS, 720x576), ifoedit is writing in the headers that the DVD is NTSC although the subtitle file was rendered in PAL resolution and I chose PAL before muxing m2v, ac3 and sup!
After I tweaked the VIDEO_TS.IFO and VTS_01_0.IFO with the proper values for the movie (PAL) using Ifoedit I was able to use the makemkv and the subtitle is placed in the proper position (exactly). I guess that is why the subtitle was getting lower, makemkv was reading that the DVD was NTSC and it rerenders sup to idx+sup into 720x480 and not 720x576 like it was in original shape.
I hope I made myself understood.
