Ok, Ive been fiddling with trying to get quicktime selectable subtitles, and Ive managed it! :)
The only thing is I get a shadow bar across the video underneath the sub and I cant figure out how to get rid of it. :mad:
Maybe someone will be able to give input with this?
Here how Im doing it:
Tools:
Quicktime Pro
Dumpster
So I create a timed text track in Notepad, then open it in QT and export it to a 3GPP movie.
I then open the 3GPP file Ive just created and do Select All > Copy.
I open my mp4 video file and go Edit > Add to Selection and Scale. This adds the 3GPP file into the video file. Under Movie Properties you can alter the position if you wish. Then save this as a self-contained movie. We now have the subs in place, but theyre not selectable.
To make them selectable we need Dumpster. This bit is slightly tricky, so only do it on test files at first.
Open the self-contained movie in Dumpster, and doubleclick on 'moov' Movie resource atom. Then doubleclick 'trak' Track atom. You will see 2 or 3 of these, you want the bottom one, since the subtitle track was the last one added to the file.
Now doubleclick 'mdia' Media atom, then 'hdlr' Handler reference atom. You will now see several settings, one of which is Component subtype. It will be set to 'text'. We need to change it to 'sbtl'.
Unfortunately, Dumpster works in hex, so we need to change the hex value. Click on Component subtype, and the hex value will appear in the bar at the bottom of the window.
Look for the last $ on this line, after this there will be an 8 digit number. Replace this number (not including the $) with: 7362746c Click apply, and you will see the 'text' setting change to 'sbtl'. Close Dumpster.
Reopen your movie in QT, and the subtitles will now be selectable, albeit with the shadow bar mentioned previously. This will also work in iTunes, but Im not sure about the Ipod, I dont have one to test with.
Hopefully there is somone on the forum perhaps is a bit more knowledgable about atoms etc who might be able to take this further to remove the shadow bar completely?
Cheers
