Hello,

I'm trying to store 16-bit uncompressed PCM in an MP4 container. Searching around, most people are of the opinion that this isn't possible, yet the "twos" codec usually associated with QuickTime is an ISO-registered tag for MP4: www.mp4ra.org/codecs.html

My searches also indicated that certain camcorders produce MP4s with this audio codec, although most tools then can't handle/play them.

Is anyone aware of any tools that can produce MP4s with this codec? :confused:

But I can't say I've seen any which have AVC video and PCM audio placed within the .MP4 container...

Does anybody have any samples?
