A very small number of NTSC players (such as Apex and Most NTSC players can't play PAL discs, and most NTSC TVs don't work (Sound is not affected by video conversion.) Because the quality ofĬonversion in DVD players is poor, using 60-Hz PAL output with aĬompatible TV provides a better picture than converting from NTSC to Proper "on the fly" standardsĬonversion requires expensive hardware to handle scaling, temporalĬonversion, and object motion analysis. Standards-converting PAL players that convert from an NTSC disc to True NTSC output when playing NTSC discs. Some players have a switch to choose 60-Hz PAL or True 3.58 NTSC from NTSC discs, which requires an NTSC TV or a The player uses the PAL 4.43-MHz color subcarrier encodingįormat but keeps the 525/60 NTSC scanning rate. These multi-standard players partially convert NTSC to a 60-Hz PAL (4.43 (See the chart atĪlmost all DVD players sold in PAL countries play both kinds of discs.

Only a fewĬan make virtually perfect conversions, and they typically cost well I'm a stickler on this topic because it is I lifted the item below from the DVD FAQ websiteĬommercial DVD player does any kind of "serious" standards conversion,
(I'm not currently affiliated with an archiving institution, but I am interested in the moving image archiving field.) I'll try to research and find a technical explanation of how the PAL conversion may have advanced in quality since the DVD FAQ section on it was written.
But it works great for playback, and I've watched a couple of PAL DVDs on it recently. I don't presume to know if it is of high enough quality for purposes of transferring. It is good, though, that the article emphasizes that it's very important to confirm that the player does convert PAL before buying.Īlso, I'm talking about the quality as being flawless for purposes of watching at home or at work as if I were watching any normal NTSC DVD. Because of my lack of specific technical knowledge in this area, all I can think is to offer to give you a demonstration! :) Perhaps the technology of converting PAL for display on NTSC TVs has gotten better. Eric, the only thing I can think of is that possibly the portion of the DVD FAQ you're quoting (which is great and I use it as a reference too) might be slightly outdated.
