Thanks for the replies!
Perhaps I should be more verbose in what I wish to do...
At our convention, when we project our fansubbed shows often the subtitling gets cut off on the display. It does not matter if the subtitling is at the top or bottom, both edges get cut. We've tried adjusting the projectors but to no avail. If the show is in 16:9, we don't have this issue, it is only shows in 4:3 that get cut off.
The same issue happens with some TVs when showing fansubs. My previous TV had no problems with cutting of subtitles but my newest TV cuts them right in half. This makes me think that it is a display issue and not the video. We use in-house equipment at the local university so I can only do so much to their systems. Heck, if I had enough systems (and the ability to rewire the set up) I just jack in bunch of towers that have the correct codecs and play our shows that way... But I don't think the university would take to kindly to us rewiring the in-room A/V system
I said before I don't want to lose the aspect ratio because I want to maintatin the original video as much as possible. I can quite easily convert 4:3 shows into 16:9 but then the image quailty changes and everything looks stretched/squished. If this is my only only option I'll do it but I've come to a-m-v.org to look for help.
All of our shows are on DVD so the source has to be editted. Thusly the idea to add black bars to offset the image so that when displayed, the subtitles remain visable. My first idea is to center any 4:3 shows on a black frame. While I don't think it's this simple, my idea is like setting a 800x600 image on top of a 1024x768 black background so that it is framed by black bars. That way when the show is projected, it should be centered on the screen with no cutting of subtitles no matter the location of those titles.
Does this explaination help at all?
