Sorenson Video 3 Pro Codec for MAC is the first choice for QuickTime media compression. Video 3 Pro integrates seamlessly with most popular third party NLE software including Apple Final Cut Pro and iMovie, Avid Xpress DV and Adobe Premiere. It also integrates with all popular compression applications including Sorenson Squeeze, Apple QuickTime Pro, and Discreet Cleaner.
Improved Performance
Improved video quality at less than half the bit rate of Sorenson Video 2. 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.
Color Watermarks
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
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.
Bidirectional Prediction
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.
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
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 does not 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.
