3ivx D4 4.5.1 Pro is an MPEG-4 suite that is used in MPEG-4 formats such as MPEG-4 Audio and Video. It is a decoder capable of playing MPEG-4 video variants such as Apple MPEG-4, XviD, Philips MPEG-4, and DivX 5, 4, and 3, as well as, MPEG-4 AAC Audio, and audio encoded by iTunes and Nero AAC. This application is capable of compressing audio and video to a portion of their initial size, all the while sustaining high quality MPEG-4 file outputs.
Videos of almost DVD quality can be streamed over a DSL or cable mode. A CD-ROM can also hold about 2 hours of DVD-like quality video and audio. It is also appropriated as a plug-in for DirectShow, Video for Windows, and QuickTime Player. Thus, MPEG-4 videos can be encoded using encoding applications that are QuickTime compatible. The application can also play MPEG-4 files by means of Windows Media player and other players that are compatible with it. Other features include a file timestamp facet, Variable Frame rate option, and compatibility with an MPEG-4 variant released by a number of Digital Video Recorders. Whatever scaling or cropping has been done to MPEG-4 files, the application ensures preservation of media’s DAR.
