OK, so I searched the site and didn't find the answer to my dilemma, so I hope someone can clear this up for me. (sorry if this is the wrong place to post this but I couldn't find a more suitable one).
Here it goes: As I understand, the interlacing artifacts appear on common monitors because of their progressive display. But the strange thing is, not all movies with interlaced content appear interlaced on my LCD monitor. For eg.: 25 FPS PAL interlaced movies appear as if they were progressive (no interlacing artifacts, no matter which program I open them with). Then there are the 29.970 NTSC interlaced movies which definitely appear interlaced on my monitor (again, no matter which program I use to open them). Then there are the 25 FPS interlaced movies captured from my Panasonic Video Camera (these also appear VERY interlaced as if they were NTSC and require a lot of work with scripts like mvbob to deinterlace --- so what's the difference between these 25 FPS interlaced videos captured with the camera and the 25 FPS interlaced movies from original DVDs which don't appear interlaced? Another thing, the 25 FPS interlaced movies, which look like progressive content on my computer, appear interlaced on other computers (I have an nVidia video card, while the computers where there are interlacing artifacts have ATI video cards. Could this be it? My card can automatically deinterlace some videos? But why not all of them? Why not the PAL interlaced content captured with my video camera? I would really appreciate it if someone could answer my questions and solve my mystery. Thank you.
