[FFmpeg-user] iTunes aspect ratio

[Antoine Baqain]

Hello,

Hope my words find you all well.

I need your help in a matter that I can't find a solution through searching
on fixes for it.

I'm on an iMac 3.4GHz i3, 4GB of RAM, and x86_64 arch, and I'm trying to
convert an AVI (DVDRIP as they call it), apparently a torrent movie :), and
I'm using the following command (includes all info about source and output)
:

ffmpeg -y -i "Baby Einstein Baby Da Vinci 9 mos+.avi" -f mp4 -vcodec mpeg4
-b 40000 -acodec libfaac -ab 192k  *-aspect 16:9* output_file.mov

I bolded the aspect that I needed since from source it is 4:3, and I have a
LED screen with 16:9 with apple TV 2.

My problem is that, opening the output file through VLC, it opens with 16:9
aspect ratio, but in iTunes (which reflects Apple TV 2) it opens with 4:3
aspect ratio, please tell me if I'm missing any other option for ffmpeg and
recognized by iTunes / Apple TV 2 that would convert the video with 16:9
aspect ratio.

Regards, Tony.

P.S: please don't tell me to use any application such as hand break or
something, they all use ffmpeg and they output the same as my ffmpeg CMD,
but much slower (UI complicated also when you get into advanced options).
