5.1 audio routing within quicktime / mp4
on Oct 26, 2015 at 12:16:54 pm


I have been doing some tests regarding export of quicktime/mp4 container - with different video codecs (H264/Prores) and 5.1 routing (PCM/AAC).

As far as I know these 5.1 routing standards exists:

and in one or the other programm (I have tested Clipster, Compressor, MediaEncodeer etc), I found this type of routing CLRLsRsLFE especially attached to AAC. (and in Compressor also LRLsRsCLFE)

Has anyone more infos on these types of 5.1 routing attached to certain codecs/containers and types of players?
And who is responsible for the routing (metadata) in Quicktime (Quicktime itself, the type of codec I use or the programme I use) I am looking for more infos on this topic.

Also is it possible to mulitplex AC3 with video into one file (not via a videoplayer)? Or is it purely for DVD/BluRay authoring?

Thanks :-)
