Matroska aspect ratio

[vlada]

Hi, can somebody explain me something about aspect ratio in matroska files? First of all is there a player supporting it? I tried it, but it didn't work neither in TCMP nor in MPC. Another problem is, what would it do with subtitles. Lets say, i have movie in resolution 768x576, with aspect ratio 16:9. So I would need the decoder (FFDShow) to resize the movie to 768x432, then VobSub to add 72 pixels of black stripes to bottom and top (to make the picture 4:3 again) and then VobSub should display the subtitles in these black stripes below the picture. Could it even work like this? I hope You understand what I mean. And another problem - what subtitle format sould I use with Matroska? If I use .srt, vobsub ignores tags for italic and bold text. I tried SSA but then I couldn't change the font in VobSub. Does anybody can help me, please? Thanks in advance, Vlada

AR correction works perfect in TCMP, and since RC3. Just make sure you have the newest CDL ( v.1.6 now ) from http://downloads.matroska.org/downloads/cdl

DVobSub should do this automatically, and if you dont like where the subs are displayed you have many ways to set this in the DvobSub setup.

And another problem - what subtitle format sould I use with Matroska? If I use .srt, vobsub ignores tags for italic and bold text. .... you sure using the latest DVobSub ? Its called vsfilter.dll now and you can get it from the Guliverkli (http://sf.net/projects/guliverkli) homepage.

I tried SSA but then I couldn't change the font in VobSub. Does anybody can help me, please? Thanks in advance, Vlada ... the fonts have to be set in the SSA subs itself AFAIK ...

So I would need the decoder (FFDShow) to resize the movie to 768x432, You would want to encode the movie at a smaller resolution horizontaly to take full advantage of the anamorphic feature. IE, encode a movie at 512 x 272 or 544 x 272 and then have it resized automatically to 640 x 272.

The AR correction works fine, but if the file contains chapters, CDL 1.6 causes TCMP to freeze with 100% CPU usage upon opening the file :(
