Yet Another MPEG4 Codec: 3ivx
3ivx D4 4.5 – MPEG-4 Audio and Video Compression. Recently got a Mac encoded file in 3ivx format. It’s another MPEG4 encoder. You need to download a plug-in to have it work with Windows. Or use Quicktime.
Amazing how many codecs I now have loaded on my machine. 3ivx, Divx, xvid, Windows formats, etc.
