I am trying to encode an avi file to mpg2 with Tmpgenc Xpress 4. I usually just let DirectVobSub do the work of encoding subtitles, via DirectShow. However in this case the video is a very epic widescreen, like 640x226 or something similar. With this aspect ratio, the subtitles straddle the line between the video and the black bar if I just encode using DVobSub. There's plenty of space down there for the subtitles to sit directly below the video without cutting into it. But I can't figure out how to simply move the subs down 30-40 pixels. There is an "override position" type feature in DVobSub but it doesn't seem to do anything, no matter how I set it. The subs are SRT and I tried loading them in Aegisub to see if I could do anything in the .ass format. But it's kind of impossible because Aegisub displays video as is; the black bars aren't filtered on yet. What do I need to do to lower the subs? Is it even possible using Tmpgenc and DVobSub or do I need another method? Any help appreciated, I thought this would be a common problem but I've googled about 50 phrases and can't find anything useful.
You might try DVDSubedit File => Open Full Domain.(usually VTS_01_1.VOB). You can select the sub pic stream on the top right of the window There is a slider under the preview screen that steps through the subs and a control to modify the vertical position. 'Edit' => 'Apply last changes to all' will apply the change to all subtitles. 'File' => 'Save all modifications' will make the change immediately to the movie with no 'undo' possible. It's better to make the changes on a backup and consult the help file. http://www.afterdawn.com/software/video_software/subtitle_tools/dvdsubedit.cfm
Thanks for offering that method, but I found a better way for my purposes...I just created a tiny avisynth script that resizes the avi to DVD width (720), and adds borders on top and bottom. A little simple math was all it took. Now the position adjustment in dvobsub works and all is well
