AirPlay 5.1 surround

[Jeremy Garchow]

I had read about using handbrake for this, and I have handbrake, but I have never really been truly impressed with handbrakes results. Perhaps I’m holding it wrong and I’ll give it another shot. It won’t read 5.1 from FCP7 (due to the channels being 1 stereo, 2 mono, and 1 stereo despite having the channel assignments in the correct order), but an FCPX surrounded export does provide the proper metadata to handbrake (5.1).

If this does work, though, it will be nice as it’s one step instead of a three step Subler workflow.

[Keith Koby] “Not to talk bad on episode, but even if you do get the pro audio option, you have to use the channel mapper to rearrange audio into the order they expect (which by the way matches no industry standard).”

1 to 2
2 to 3
3 to 1
4 to 6
5 to 4
6 to 5

Because of all the testing, it is now committed to memory, or rather, an episode preset 😉

Thanks so much, Keith. I’ll post back about handbrake results. Much appreciated.

Handbrake does the same thing as episode without the channel map.

Takes L, R, C, Lfe, Ls, Rs and outputs L, C, R, Ls, Rs, Lfe. The file sounds weird on non surround devices due to the flip-flopped order.

The video looks good though! 😉

Funny thing about AirPlay;

I can get almost any crappy web video to stream to the AppleTV and it displays it no matter of format, frame rate, audio, etc, happily playing on any NTSC/HD compliant TV via hdmi

When trying to get AC3 on an iDevice for streaming, it chokes and won’t transfer.

Streaming from a computer works just fine with AC3.

Dolby Digital and ProLogic II AAC work just fine on iDevices, but it doesn’t sounds like AC3 5.1.

I have learned more than I wanted to know. I can’t wait to go back to exporting surround stems. It’s so much easier!
