Convert mov(audio+text subtitle) to 3gp (video) — Fri, 22 May 2009 15:56:13 +0000

Thanks a lot for your great website !!!

I am working on this for several nights with no answer

I am trying to convert mov(audio+text subtitle) to 3gp (video)

I am using this command ( I compiled the ffmpeg, libamr-nb, libamr-wb, libfaac packages):

ffmpeg -i input.mov -s qcif -r 12 -ac 1 -ar 8000 -b 30  -ab 12.2k  -t 60  -scodec copy output_sub.3gp

but I cannot see the subtitles , not in the PC and not in the mobile.

Maybe I need to convert the mov to 3gp movie stream ( how do i do it ? )? If you could please help me – i will be more than grateful !!! Thanks u so much !!! I am desperate !!!

Jor

I tried to contact that anonymous guy asking him why he was so secret, but he never answered me…

About his technical question: yes, you can do that and it’s pretty easy thanks to ManDVD, a GUI tool to build slideshows.
