Hi all,

Here are the specs of Youtube (sorry in french):

http://support.google.com/youtube/bin/static.py?hl=fr&guide=1728585&topic=1728573&page=guide.cs

I would consider anything that is recommended in this link (for 1080p,
720p, 480p, 360p and 240p).

Here is an example with FFmpeg (720p specs) :

/home/toto/ekd_toto/linux_dependances_portables/ffmpeg/ffmpeg  -i
"/home/toto/blender/dronez.MOV" -f mp4 -c:v libx264 -b:v 5000k -vf
scale=1280:720 -aspect 16:9 -c:a libvo_aacenc -b:a 384k -y
"/home/toto/a/nouv_EKD/video/version_3/transcodage_vidéo/23_09_12_essai_nouveau_h264_mpeg4_avec_du_mov.mp4"

The result is good but if it can be better (and in accordance with the
recommendations of Youtube) ...

A question, what's that: Débit audio 5.1 ?, How to include it in the
FFmpeg syntax?

Thanks in advance.

PS; my FFmpeg version:

ffmpeg version N-44443-g570931d Copyright (c) 2000-2012 the FFmpeg developers
