melt -profile dv_pal_wide consumer:decklink:3 profile=atsc_1080i_50 -consumer decklink:0
This melt command produces something else than my downconv.rb script: https://gist.github.com/3805493 Melt does loose the correct aspect ratio. When I pipe the result through OBE encoder, the output is 4:3. When I use the script at gist, I get the correct aspect ratio. Markus PS: Don't mind the actual card indices.
