I just find it a bit more complicated in Premiere, probably because I've got used to doing it the Pro Tools way. This is a bit counter intuitive to us audio engineers, as we've got used, with Pro Tools at least, to being able to change our configuration after initial setup. Tracks 5-10 - Final Mix 5.1 - L,R,C,Lf,Ls,Rsįirst I had to set up the Premiere sequence.I've recently had the need to use Adobe Premiere Pro to make master delivery video files.Īrmed with a delivery spec, I set about making a 14 channel HD video with the following audio spec.
This is because we users have no control over how Pro Tools interfaces with certain third party software and how Avid relying heavily on them affects us. You can clearly see (and hear) that the resulting stereo fold down is wrong. The track above is the original source, in the Pro Tools internal config order of L,C,R,Ls,Rs,Lf. The blue track is the resulting fold down. Things get even worse if you want to embed an MP3 of your mix instead of a WAV in your video.

If you re-import that movie back into Pro Tools, it plays correctly. If you play it on Windows Media Player, or import it into Premiere, it plays correctly. So if you play a 5.1 movie file generated by Pro Tools, on Quicktime or VLC, the centre channel is coming out of the right, and all manner of other weirdness. Historically in the days of DTRS and ADAT, it was deemed that only AES pairs were truly phase coherent, so they arranged the channels in an order that made sense for that.
The SMPTE (Society of Motion Picture and Television Engineers) track order that the likes of QuickTime and VLC expect is this. Pro Tools' internal 5.1 track designation is locked to the following -Īnd it exports interleaved WAV files in that order. However, QuickTime and VLC go by the track order. When you create an interleaved multi-channel WAV in Pro Tools, it gives each channel a flag or ident, which most software can interpret correctly on import. While some video codecs do not allow for discrete tracks, a lot do. When you do an Offline Bounce to QuickTime with a 5.1 audio source, it only gives you the option of a 5.1 interleaved WAV or a mono-summed WAV.
