Comment (by edumj):

 I've tested, and it seems that DivXMux does this:
 1-Crop every bitmap (like SubRip).
 2-Pad them to 640x480 (bottom center aligned).

 VLC captures with a yellow drawbox to see subtitles full size:

 DVD Subtitles extracted to IDX/SUB are 720x576:
 [[Image(http://i47.photobucket.com/albums/f169/edumj/IDX-
 SUB%20720x576.png)]]

 IDX/SUB Subtitles converted to XSUB with DivXMux are 640x480:
 [[Image(http://i47.photobucket.com/albums/f169/edumj/IDX-
 SUB%20to%20DivXMux%20640x480.png)]]

 You can see original upper subs go down with DivXMux because of the
 cropping an padding. They look not well bottom-centered in VLC, but ok in
 TV.

 I don't know if ffmpeg can do this automatic cropping and padding to
 640x480, but at least it could scale them down to 720x480 or better
 640x480.

Comment (by edumj):

 Ok, with lower video resolutions (like 320x480 and 640x480) they are also
 cutted, and look exaclty the same size as with 720x576.

 Wiht higher resolutions (like 1440x1080 and 1920x1080) they are full but
 smaller, because they are scaled down and top-center aligned (if I made
 them with DivMux they also scaled down, but appear in an upper position
 because of their 480 height)

 I can make some captures if you want.

 Txt2VobSub makes 720x576 and 720x480 IDX/SUB (acoording to "size" in .idx
 file), but I found out that they really are 720x576 always and they just
 get cutted when .idx says "size: 720x480" (because the lower parts of the
 bitmaps are empty and it's ok to cut at 480). I mean, they must know that
 the max height for XSUB is 480 and they don't put subtitles lower tan
 that.

 I'll try what happens with DivXMux and full height 720x576 VobSub
 extracted with Mencoder, because when I extract them with PGCDemux and
 convert to idx/sub with sup2vobsub, upper subs go down and I don't know if
 DivXMux scales down to 640x480 or just aling bottom (but then the upper
 subs should be cutted!?)

 I wanted to ask you to test what happens if you put xsub subtitles into
 videos with both higher resolutions like 1440x1080 and much lower
 resolutions than pal or ntsc but I don't have command lines to test right
 now.

Comment (by edumj):

 Well, the PS3 allows AVIs with higher resolutions, I've tried with
 1440x1080 and XSUBs, and the subs were very small... And any other
 resolutions (720x540, 700x400, 720x400, 640x... etc..)

 I also tried with 2 LG DVD Players, and 3 different televisions (CRT, LCD,
 and 4K LG Smart TV) so, the problem it's not the TV nor the Standalone
 Players. It's something about XSUBs resolution specification.

 Did you tested it in your TV? Mine are all PAL. Anyone can try if it
 happens also in NTSC Players?

 I can make PS3 captures if you want.

 Do you know how to extract bitmaps from .sub? Subrip doesn't seem to work
 with idx/sub...

 Also, I could author a NTSC DVD and a PAL DVD, and put 720x480 and 720x576
 subpictures, for testing size or offset changes...

 Does your TV only allow playback of PAL and NTSC mpeg4 asp in avi or also

Comment (by edumj):

 One more strange thing:

 With same IDX/SUB (made with Txt2Vobsub or extracted from NTSC DVDs) muxed
 with ffmpeg or divxmux, they look different in VLC (x and y position):

 ffmpeg:
 [[Image(http://i47.photobucket.com/albums/f169/edumj/Starship_Troopers-
 ccextractor-xsub-ffmpeg%20720x480%20oacute%20720x576iquestiquest.png)]]
 divxmux:
 [[Image(http://i47.photobucket.com/albums/f169/edumj/Starship_Troopers-
 ccextractor-xsub-divxmux%20640x480.png)]]

 But in TV, only y position is different!

 ffmpeg:
 [[Image(http://i47.photobucket.com/albums/f169/edumj/Starship_Troopers-
 ccextractor-xsub-
 ffmpeg%20720x480%20oacute%20720x576iquestiquest%20en%20TV.png)]]
 divxmux:
 [[Image(http://i47.photobucket.com/albums/f169/edumj/Starship_Troopers-
 ccextractor-xsub-divxmux%20640x480%20en%20TV.png)]]

 And they are the same size, even ffmpeg says they are 720x576:
 {{{
 Stream #0:2(es): Subtitle: xsub (DXSB / 0x42535844), 720x576 (default)
 }}}

 I don't know which size are really IDX/SUB made with TXT2Vobsub in .sub,
 but in .idx it says 720x576 (it's not reliable), and may be that's why
 ffmpeg says that?

 ffmpeg:
 {{{
 "ffmpeg" -palette
 
"00,00,ff,ff,00,00,00,00,00,00,00,00,00,00,00,00"

Comment (by edumj):

 They are Ok. XSUBs keep same size and position as the input file.

 I supose ffmpeg always keeps xsub original size (640x480 re-scaled by
 DivMux), but if vobsub has an original size of 720x576 (PAL DVD
 Subpictures) without re-scaling, they are too big for a xsub.


 I think XSUBs where made not thinking on PAL... and only right resolutions
 are 640x480 or 720x480, because NTSC DVDs look Ok!

Comment (by edumj):

 Ok, I found this VOB in yours sample folder:

 https://samples.ffmpeg.org/sub/starwarssub2.vob

 It's PAL and has lots of Vobsubs.

 I convert it to AVI, scaling video to 720x400 (with scale filter) and
 embeding XSUBs with this:

 {{{
 "ffmpeg.exe" -palette
 
"00,00,00,00,00,00,00,00,00,00,00,00,00,11,ff,00"

 scale=720:400,setsar=sar=1/1 "starwarssub2 a xsub, scale 720x400.avi"

Comment (by edumj):

 Ok, I will, but I found this sample in your samples directory
 https://samples.ffmpeg.org/sub/small.divx and they have the same problem:
 ok in VLC, but too low in TV (half off the screen).

Comment:

 If you want to help with this ticket, please provide the FFmpeg command
 line that produces the incorrect output together with the complete, uncut
 console output (and point to the input sample) and, if possible, a
 "correct" output from the same source.

Comment (by edumj):

 With '''DivXMux.exe''' the subs are Ok, and it always makes Subtitle Track
 of 640x480 with any video resolution (like 720x540). May be that's why
 subs are too low if '''ffmpeg''' takes 720x576 as the sub resolution, when
 the video was changed from 720x576 to 720x540 to make it square pixels.

 There should be some way of passing '''xsub_encode''' fuction '''width'''
 and '''height''' parameters (and not let it take video source resolution)
 or just make xsubs always 640x480 like '''DivXMux''' does.

Comment (by edumj):

 I don't know if it's a bug of DivX subtitles, because I remember also
 happened with AVIAddXSubs, but it can change the Vertical Position of
 subtitles.

 But, in the source code https://www.ffmpeg.org/doxygen/0.6/xsubenc_8c-
 source.html I think there are x, y, width and height parameters. It should
 be possible to change them, although subs may be higher in VLC, but they
 will look ok in PS3.

Comment (by Cigaes):

 Currently, FFmpeg has almost nothing to manipulate the contents of
 subtitles (either bitmap or text, for that matter). If your source had a
 certain resolution, then most likely the output file will have subtitles
 with the same resolution, and there are no options to change that.
