In Reply to: In many cases you are right, but in many DVD are better than that. posted by Ole Lund Christensen on February 23, 2008 at 13:11:42:
I own nearly 2000 DVDs, from Regions 1-4.I have compared hundreds of Region 2 and 4 DVDs with their Region 1 counterparts. My reviews are posted on www.michaeldvd.com.au.
Apart from a few exceptions, my experience is that Region 1 NTSC DVDs tend to have superior audio and video quality, compared to Region 2/4 PAL DVDs.
There are a few other sites doing these comparisons. You will find on most of these sites, the reviews concur with my experience. Many include screenshots from the Region 1 and 2/4 discs and you can clearly see the difference (in many cases less macro-blocking, less mosquito noise, less HF filtering, often better colour/contrast for the NTSC transfers).
The reason why Region 1 tend to have better transfers is because of bitrate. NTSC has lower resolution so if both NTSC and PAL are encoded at the same bitrate, NTSC will have less encoding artefacts. Plus, Region 1 DVDs tend to have fewer audio tracks, so the video track is encoded at higher bitrates compared to PAL. A typical PAL DVD tend to have multiple language tracks (English, Frech, German, Hungarian, Polish, ...).
As for the 4% speedup, as I mentioned, this occurs on all transfers that originate from 24fps film. Yeah, there might be a few concerts and documentaries based on 50Hz sources, but these are very much in the minority. If most of your collection consist of these sources, well, good on you. Me, I prefer watching transfers from film.
