I have an MKV and i want to add hard subtitles with a 'black box' background. Unfortunately, i can't find out how to do this despite some hours reading about the various plugins. Can anyone please tell me how to write an appropriate script?
As a corollary, after i gave up trying to encode the subs with avisynth, i used a simple script to open the MKV in virtualdub and used the textsub filter to achieve what i wanted to do. However, although the preview looked fine, the resulting avi (which took around 11 hours!) won't play in any media player. And if i try to open it in mkvmerge, i get 'the input file does not contain any tracks'. Mediainfo shows just a video file whether i convert the audio to lame mp3 or check the 'no audio' option. Any ideas what is happening here?
Thanks
