PGS subtitles out of scale in resized Bluray MKVs
Posted: 20 Sep 2012 21:52
Hello, I already posted my issue a week ago by adding it to an existing post from another user in the General VLC media player Troubleshooting section (viewtopic.php?f=2&t=103641). However, since I have not received a single reply, I'm wondering if I posted in the correct section. I'll give it a second go here:
I converted some 1080p Blurays to a 720p MKV with Handbrake (latest nightly build) and the PGS subtitles are out of scale. They are far too big, as if VLC "thinks" that the movie display size is still at 1920x1080, and not 1280x720 pixels, as can be seen in this screenshot of the 720p movie: http://i.imgur.com/xlVBJ.png. This is the same scene at 1080p with nicely-sized subtitles: http://i.imgur.com/gbHy6.jpg.
The subtitles are displayed correctly with MPC-HC and the WDC TV Live SMP. Hardware players are usually rather fussy so I would expect that the WDC TV Live would have trouble displaying wrongly encoded PGS subtitles properly, but it doesn't. For testing purposes, I converted the same Blurays to MP4 with Handbrake and the subtitles are OK when played with VLC, so the issue seems to be limited to rescaled MKVs.
So this makes me wonder if there could be another reason than Jean-Baptiste's explanation from the other post (wrong PGS encoding). Is it rather something within VLC? Or maybe it's just something in my VLC settings?
Any help would be appreciated. Thanks.
