no really for me the main problem was it seemed not to pick up fast 
movements I can't recall exactly now whether it was additionally 
'muddy', don't think it was but...

unfortunately aegisub really just didn't work, complained about no video 
provider ( or some error that sounded vaguely like that ). From looking 
around it appeared it should use ffmpeg but aegisub didn't see it and 
didn't provide a way for me to point it at it ( there was a box in the 
options for choosing a video provider but it was grayed out, there was 
also a config file I tried to hack all to no avail )  so I just gave up :-(

as interesting as the arcade of options to the various tools above is ( 
thanks for posting them :-), sometime I will find the time to look at 
them more closely ) what I really was after was a way to go from ogv 
video file ( or .ass if you prefer ) -> ogv file with re-encoded 
subtitles ideally *without* the need to download restricted formats [*] 
not sure if the info above tells me that, I guess I need more time to 
study what's there more


[*] not that I am not adverse to downloading restricted codecs and the 
like but I tend to keep my work desktop machine clear of stuff from 
non-distro ( e.g. packman and the like ) repos that can cause zypper to 
complain about this version and that version of this and that 
conflicting etc. when upgrading installing etc.
