There have been various queries about changing the characteristics of the Sun Study caption. This is how I do it...The principles are those for closed captions for movies (subtitles, etc), which some bright person at Graphisoft has commandeered.
These settings are based on a sun-study frame-size of 800x600...
Open the sun-study in Quicktime 7. Export the caption(File/Export): choose "text to text". In Options select "Show Text, Descriptors and Time" and "Show time relative to start of Movie".
Edit the .txt file in Wordpad or whatever. Thus: switch font to, say, Arial; the {plain} definition can be replaced with Italic, Bold , etc. {Size:24} or whatever. The two colour boxes {textColor:...,...,...},{backColor:.,.,. }go from 65534 down: 65534,0,0 = bright red: 0,65534,0 = bright green; 0,0,65534 = blue, etc. These are useful if you want the date and time in a clean box -- see below. As to {justify: Left, Right or Center}(note US spelling) -- I tend to leave it on Left and move it around later;. Save the file, (if you want, with a different file name so that you can fiddle without fear) ANSI encoded.
Open in Quicktime (Scroll to "All files"). Select All. Copy. Open your Sun Study. You can turn off the existing caption by going to Window/Show Movie Properties, but you don't have to. Add to Movie (Ctrl, Alt, V). Horrors: if you haven't changed the text box size you see a white screen.
Open Window/Show Movie Properties (Ctrl+ J): Highlight your new Text Track (probably Track 2). Open the Visual Settings tab. Find Transparency. Choose the setting you want -- I quite like Premultiplied Black if I'm keying a black caption. However Offset takes the caption left or down; if you offset down by more than the overall frame height of the study itself you will create a caption box outside the normal picture area.
If you don't want to do that the function Transparency: Dither gives you a nice box over your picture. Make sure the layer number is low enough for you to see the caption in this case. The other Transparency settings are trial and error, and the result depends on your text and background colour settings. I always click the high quality box, but I've never noticed much difference. Close the box. Play the movie, Save it with a different file name. Then read the Quicktime guide for more options.
That really is about all I can tell you. I hope it's useful...I think there must be something about it in the QT manual, though that was written years ago and is possibly out-of-date
