Features

Virtual Multi-Pass Encoding
CCE-MP performs multiple "on memory" passes (between 2 and 8) during each "physical" encoding pass to ensure precise correlation between distortion level and available bitrate before actual output. This enables CCE-MP to achieve the highest picture stability and the highest picture quality without unexpected fluctuation in both bitrate and distortion.

Multi-Pass Encoding
CCE-MP allows 3 to 99 physical passes for multi-pass encoding. By repeating passes, the picture quality can be automatically improved.

Advanced Adaptive GOP Structure
CCE-MP will simulate thousands of possible GOP structures based on the motion detection, then automatically adapt the most effective GOP structure for the video sequence.

Advanced Adaptive Quantization Matrix
CCE-MP with AAQM functionality creates variation matrices such as x 1/4, x 1/2, x 1, x 2, and x 4, and applies an appropriate one automatically. Thus, CCE-MP achieves the highest quality without time-consuming adjustments of the quantization matrix.

Automatic Field-based Scene Change Detection
During the encoding process, CCE-MP scans ahead of a current frame so that approaching video data can be captured. The pre-scanned data is then rapidly analyzed to identify the first frame of an approaching scene. CCE-MP then automatically sets the first frame as an I-frame of the Closed GOP.
