Description (last modified by cehoyos)

Hi there, I have ffmpeg installed via macports on a mac running 10.9.3 I am trying to convert an mpg from a video camera so that it can be encoded to burn to a pal dvd. My command is:

/opt/local/bin/ffmpeg -i '/Users/Shared/.EVNZ_config/Titles/a_opentitles.mpg' -target pal-dvd -s 720x576 -vcodec copy -acodec mp2 -ab 256k -y '/Users/Shared/.EVNZ_config/EVNZ_DVD_Temp/EVNZ_DVD/a_opentitles.mpg'

but I'm getting this error:

Conversion failed!

I can run this on an older version of ffmpeg without any issue so don't know why it's not working in this version.

I have very limited knowledge of ffmpeg and the options so please give any explanations in simple terms.

Many Thanks,
Nik
