I have several questions about interlacing, that might fit in different forums. Not sure if this one is the best, but here goes.
For one thing, I believe I read that interlacing was created to deal with limitations of CRT tube TVs. True?
However, these days such TVs are rarely used. Most people have flatscreen TVs--LCD or plasma, and also watch video on flat screen computer monitors, tablets, etc.
If the second paragraph is true, why is video still interlaced at all, considering the preceding paragraph?
Modern DVDs are still interlaced, correct? Why?
Are blu-ray discs also interlaced? Why?
I have a new camcorder, quite good, the Canon Vizia HF M500. Setting it to the highest quality HD video setting (1920x1080, I think 24mbps), but all automatic, the video still comes out interlaced. (I don't know if there is a way to set it not to interlace. I can look into that.) Again one wonders why, in this world of flat screen video viewing.
I know that if one is to prepare the video to play on a computer, tablet, or phone, one has to deinterlace it first. But for putting on a blu-ray disc or DVD, should one keep the interlacing?
With the original reason for interlacing (so I thought, at least) being gone, an ancient relic (CRT-tube TVs), I really do not understand why interlacing still exists, why cameras shoot video interlaced, etc. Can anyone explain?
