If you ar eencoding a video that is already on your computer, then given today’s powerful machines, there are software encoders that can encode much faster than realtime (might depend on the codec of your source videos). I downloaded the CCE Basic Trial program, and it encoded a 3-minute DV .avi in a little over one minute (1-pass CBR 6000kbps). This was on an older P4 3.0ghz machine — so I can only imagine how fast it would run on a more recent machine…
If you are trying to encode from a video source in realtime, there are also software solutions that will capture/convert in realtime. Mainconcept’s mpeg encoder is one that comes to mind. They have a standalone encoder, but a few NLE’s use it as their mpeg encoding engine. Ulead for instance uses the Mainconcept mpeg encoder, and it will let you capture DV source to mpeg2 in realtime (needs a strong enough machine to keep up, but I think with today’s computers that it’s manageable).
One other alternative for realtime encoding from an analog source is a standalone dvd recorder. I often record things this way, and then just import the mpeg for use in my Authoring application (to add my own menus and chapters…).
