I'm looking to transcode some of my dvd collection with Vidcoder.
Looking at the 'Normal' profile it seems to be defaulting to the x264 very fast preset. First of all, is this correct or should I be changing this to a slower setting to preserve quality?
I'm looking to do batch converting over night so I need the encoding speed to be fairly quick but not at the expense of any noticeable quality. If the only real issue is bloated file size then I can live with that.
Also, when i've experimented with Vidcoder in the past i've always used an RF quality of 20 but that was using the medium x264 setting. Would it be worth lowering the RF to something like 18 to compensate for the faster encoding speed?
I've also checked the latest version of Handbrake and that is also defaulting the x264 to the very fast preset.
Any suggestions would be appreciated. Its been such a long time since I transcoded anything and I assume x264 encoding is more finely tuned than ever now.

Veryfast, compared to say, Slow, delivers slightly lower quality. You'll see a little more posterization and slightly rougher edges on moving objects.
If you look at the file size generated by the various presets (using CRF encoding) Ultrafast and Superfast give much larger files than Veryfast. Faster, Fast, and Medium usually give slightly larger files than Veryfast. It's not until you get up to Slow, Veryslow and Placebo that you start seeing the files get a little smaller than Veryfast.
With DVD sources I usually use Slow because it only my computer about 20 minutes to convert a movie at that setting. And the small frame size will be blown up to full screen when watching on TV, so defects will be more obvious. With HD encodes you might want to use the faster presets to speed up processing. And defects won't be blown up as much when watching on TV.
