Our client wants .srt files (subtitles) embedded into an .mp4 file. They will then use their player to toggle the subtitles on and off.
After a few hours of searching, all I can find are methods involving several non adobe programs but the articles are 2-3 years old. Is there a way to do this in Premiere CS5? Can Flash or Encore do it instead?
Encore can author the Sub-Titles, and your client can toggle those ON/OFF.
Encore doesn't create stand alone .mp4 files.
Likely a non-Adobe application will be needed here.
You are correct. The output from Encore would be either to BD, or authored to Flash.
