The 3ivx decoder plays back most MPEG-4 variants (including DivX 3,4 and 5, Apple MPEG-4, Philips MPEG-4 and XviD). The 3ivx decoder produces noticeably higher quality video than other decoders due to its high quality postprocessing filters, and because of its core design and optimization maintains a record-breaking speed.
The 3ivx encoder produces industry-leading compact high quality MPEG-4 video and is distributed as a plug-in for QuickTime. This allows you to encode MPEG-4 video with any QuickTime compatible encoding application.
Why use 3ivx D4 4.5 instead of Apple MPEG-4?
1. 3ivx is up to twice as efficient as Apple MPEG-4. It produces the same quality video in half the size.
2. 3ivx is up to five times faster at encoding.
3. 3ivx is completely compatible with the Apple MPEG-4 Decoder built into and shipped with every copy of QuickTime 6.
4. 3ivx is a faster and better decoder, but you don't need 3ivx to decode.
