I have a MTS file with 5.1 sound from a sony HDR CX520.
after export to HD PAL 1080 25p i don't have 6 channels
the outpout is 2 channels.

Theoretically, it is possible by adding channels=6 to a render profile, but I think you also must supply a channel_layout=? option as well. Oh, and a acodec that supports this. I do not have experience with it yet. Feel free to learn more on the web, try it out with a custom encoding profile and provide your results feedback here!

actually it is just "audio copy" that I would be run
because the source is 6 channels audio.

thx i will search on the net for ffmpeg options.

MLT and therefore Kdenlive does not support "audio copy."

I have nothing found yet to fix my problem :-(
can i fill in a wich to have 5.1ch support somewhere?
everyting that i add to a profile don't work.
