MPEG-4 Video Encoder
The 3ivx Filter Suite

The MPEG-4 Video Encoder filter is based on the 3ivx MPEG-4 5.0 Video Core. It supports multiple Encoder Modes to cater for different uses. Real-time Encoding, Video-On-Demand, Archiving, Streaming and Multimedia Authoring are just a few of uses that the encoder facilitates.

The Encoder is available as both a Video for Windows codec that is compatible with all VfW applications such as VirtualDub, FlaskMPEG and Adobe Premiere, and a DirectShow Video Encoder for applications that use the DirectShow Framework such as GraphEdit.

The Five Encoder Modes

Single Pass - Constant Quality
Encodes the video in a single pass with a fixed quality. Video size can not be controlled or adequately predicted when using Constant Quality mode, although quality can be. [More]

Usage Example: Video Archival, Intermediary Encodes

Single Pass - Average Bitrate
Encodes the video in a single pass aiming to maintain an average bitrate. Although the algorithm is quite clever it can not produce the stunning video results which a dual-pass algorithm can, because it has no idea what video conditions will present themselves in the future. [More]

Usage Example: When you want good quality video and you don't want to or can't wait on a Dual Pass Encode.

Single Pass - Constant Bitrate
The constant bitrate mode will react quickly on bitrate spikes, lowering the image quality of the video and dropping frames if necessary. This is ideal for Live Broadcasting and Video Conferencing where the maximum quality in a constant bitrate is the most important concern. [More]

Usage Example: Live Broadcasting, Video Conferencing  
What is Dual Pass?
Dual Pass encoding allows the encoder to produce the best possible video by performing two passes during encoding. On the first pass the encoder analyzes the video and collects detailed statistics. On the second pass the encoder uses the statistics from the first pass to make better coding decisions and to distribute the bitrate appropriately over the entirety of the video clip.

Dual Pass - Best Quality
Dual Pass Best Quality encoded video will normally have the best quality and most accurate bitrate. The encoder attempts to find the highest possible average quality and encodes the video to maintain that quality. [More]

Usage Example: Video-On-Demand, Multimedia Authoring

Dual Pass - Constant Bitrate
Dual Pass Constant Bitrate encoding allows the encoder to produce video as close as possible to a Constant Bitrate by performing two passes during encoding. [More]

Usage Example: Streaming

Advanced Features
- Pixel Aspect Ratio (PAR)

The Video Encoder creates Video bitstreams that are playable by DivX 5 or later as well as MPEG-4 compatible DVD Players. In combination with the 3ivx MPEG-4 Audio Encoder and 3ivx Media Muxer, you can generate MP4 files playable by QuickTime 6 or later, Philips Platform4 Player and other MPEG-4 Compliant Players.
