Resolution Specifications SD: J2K
Avid editing applications support editing and playback of J2K media. You can import, playback,
transcode, and consolidate these resolutions. All J2K resolutions are encoded with variable
bit-rate (VBR) encoding to meet a target, average bit-rate. Depending upon video content, the
actual average rate will vary.
The following table provides J2K specifications by project type.
Resolution Specifications: AVC-Intra with AVC-I Codec Module
The following information applies if you have the Nitris DX with the AVC-I codec module
installed. The codec module provides real-time encoding to the AVC-intra compression format,
using the 10-bit high definition H.264 intra-frame codec.
This module allows for real-time baseband capture with the Nitris DX and allows real-time
performance for most rendering and mixdown operations.
When you start your Avid editing application, it detects the presence of the AVC-I codec module.
It will use the module for capture, render and mixdown. If the module is not present, the editing
application uses the software codec to perform these operations. Although, baseband capture of
AVC-I is supported only with the hardware codec module.
The following table provides AVC-Intra (with AVC-I Codec Module) specifications by project
type.
