Video 3 Pro Codex: Mac Upgrade ESD
Sorenson Video 3 Pro Codec
Sorenson Video 3 Pro is the professional's choice for delivering high-quality video compression for QuickTime media. It can be used with many popular editing tools including Adobe Premiere, Apple Final Cut Pro and iMovie, and Avid Xpress DV.
Sorenson Video 3 interfaces with Sorenson Squeeze, Apple QuickTime Pro, or Discreet Cleaner compression applications.
With Sorenson Video 3, you can get better video quality than Sorenson Video 2 at less than half of the bit rate. Sorenson Video 3 delivers twice the compression speed as Sorenson Video 2 and three times the speed when using Variable Bit Rate (VBR) compression.
Support for alpha channel/chroma key
Sorenson Video supports chroma key effects, which allow you to remove a specified color from a video clip so that other video can be inserted in the deleted area.
Watermarks, such as still images and logos, can be added to a video clip to show identity or to protect content. If a watermark created with Sorenson Video is removed from the compressed video, the video will not play.
Automatic keyframes through scene change detection
Automatic scene change detection enables the encoder to sense a scene change, produce a key frame, and allocate more resources (bits) to maximize video quality.
The Sorenson Video compressor analyzes frames before and after the bi-directional frame and then creates and inserts a frame based on the average quality of both. This improves quality and coding efficiency.
Support for One-Pass and Two-Pass VBR compression
Two-Pass VBR compression produces much higher-quality video by distributing bits in an optimized method. The first pass analyzes the data; the second pass compresses the data for maximum performance based on the first-pass data profile.
Block refresh for packet loss correction
Block refresh minimizes and cleans up propagated video errors when lost network packets cause dropped video frames.
Media key support through secure encryption
Media key support through secure encryption provides very strong protection for your content.
Compression time packetization for error resiliency to packet loss
This feature minimizes quality degradation due to lost packets by inserting recognizable patterns into the bit stream. If a packet is lost, the decoder automatically picks up at another point. Thus, the decoder doesn't have to drop a frame.
Multi-processor and Mac OS X support
Sorenson Video 3 Professional takes advantage of all processors in a multi-processor machine.
