Examples of use of MPEG-4

1. And the Xvid MPEG–4–encoded AVI clips still aren‘t directly importable into iMovie.

2. It boasts a gigabyte of internal storage for music, photos and MPEG–4 video files.

3. The iPhone 3G does an admirable job supporting MP3, AAC, Audible, Apple Lossless, WAV, and AIFF audio files, as well as MPEG–4 or H.264 video files.

4. With MPEG–4 compression, this slim masterpiece allows you capture more video while using less memory, and mark special spots in your video with video bookmarking.

5. It offers benefits for viewers — who will have access to new channels and services on free–to–air — and broadcasters — who will be able to launch new services without using any new spectrum.» The upgrade to Freeview has been made possible by technological improvements overseen by Ofcom known as MPEG–4 (media streaming) and DVB–S2 (data distribution). This will increase the channel capacity of Freeview by about 20 per cent.
