Just a couple things to add and correct that the previous guys posted. DV (avi) video that you capture from your camcorder is COMPRESSED video. And yes it does have a bitrate (standard DV is about 25Mb/s – so roughly 4MB/s). If this was uncompressed the fastest computers would never be able to keep up with the video, editing would be impossible and you’d NEVER find a big enough hard drive (lol).

As far as DVD bit rates go, the maximum bitrate is (and cannot exceed) 9.8Mb/s (or 9800Kb/s). This means that the total bitrate for both video AND audio can never exceed 9800Kb/s. So let’s say your video was running at 6500Kb/S CBR and your audio was AC3 at 192Kb/s. You’d be sitting at a total of 6692Kb/s and well within the specified range. One thing to keep in mind though is that most set top DVD players have trouble playing anything with a bitrate of 7.5Mb/s or greater (due to the cheaper drives used to keep costs down). This is why many times you’ll experience trouble playing your DVD in your set top, but it’ll play fine in your computer. I usually keep all my projects under 7Mb/s (the video usually VBR with a min of 4-4.5MB/s and max between 5-6.5MB/s). You can usually get by with lower bitrates if you have a high quality encoder. I use and recommend Canopus Procoder 2.0. It does an outstanding job. Many of my 4-5Mb/s encoded videos look better than TMPGenc at 8Mb/s

There’s my 2 cents for the day
