Re: Nex6: 1080p, 60fps on camera compressed for DVD, overkill?

In very general terms, the faster the bitrate, the higher the quality.   But other factors are at play as well, such as whether or not you use a 1-pass or 2-pass encoding process.   And if your content doesn't have a lot of detail moving in various directions then you may not be able to notice the difference.

The thing to watch out for is whether or not you need the DVD to be playable on a standard DVD player connected to a television.   The DVD standard specifies a maximum bitrate for video of about 10Mbit/sec.  This was done so that all of the manufacturers knew what to expect so they could build the DVD player with a spindle speed and internal decoding circuitry that's able handle all discs.

A lot of DVD players are capable of playing back video of substantially higher data rates, but there's no guarantee that videos with higher bitrates will pay on every player.   I know for a fact that some BluRay players top out at about 16Mbit/sec because they don't spin the DVD fast enough to exceed that.  I'd guess the same applies to a lot of DVD players as well.

At DVD resolutions (720 x 480), 10Mbit/sec should be adequate if you're using a good encoder.  It's what the movie studios use for their DVDs so that they'll comply with the standard and be guaranteed to play on any player.
