What is DNXHD?
Avid DNxHD, which stands for "Digital Nonlinear Extensible High Definition", is a lossy high-definition video post-production codec engineered for multi-generation compositing with reduced storage and bandwidth requirements. It is an implementation of SMPTE VC-3 standard. DNxHD codec was developed by Avid Technology, Inc. It is comparable with Apple's ProRes 422 which uses similar bit rates and has the same purpose.

Uncompressed high definition digital video has a substantially higher bitrate than standard definition and can require powerful computers to process and edit. Other codecs such as HDV, DVCPRO HD, AVC-Intra, AVCHD, and HDCAM use compression techniques that limit the spatial and temporal resolution of the image. While suitable for acquisition, these codecs will tend to degrade the image over the multiple encode-decode cycles that are typically required during the post-production of complex layered imagery. DNxHD offers a choice of three user-selectable bit rates: 220 Mbit/s with a bit depth of 10 or 8 bits, and 145 or 36 Mbit/s with a bit depth of 8 bits.

What is M4A?
M4A stands for MPEG 4 Audio. Since MPEG-4 Part 14 is a container format, MPEG-4 files may contain any number of audio, video, and even subtitle streams, making it impossible to determine the type of streams in an MPEG-4 file based on its filename extension alone. In response, Apple Inc. started using and popularizing the .m4a file extension. Software capable of audio/video playback should recognize files with either .m4a or .mp4 file extensions, as would be expected, as there are no file format differences between the two. Most software capable of creating MPEG-4 audio will allow the user to choose the filename extension of the created MPEG-4 files.

Because of its exceptional performance and quality, Advanced Audio Coding (AAC) is at the core of the MPEG-4, 3GPP and 3GPP2 specifications and is the audio codec of choice for Internet, wireless and digital broadcast arenas. AAC provides audio encoding that compresses much more efficiently than older formats, such as MP3, yet delivers quality rivaling that of uncompressed CD audio.
