This comes up all the time. "I need to output my NTSC show to PAL VHS for a client in Europe." Or, "I want to produce my show for the best quality in both America and Europe."
There are high-end VHS machines that have standards converters inside and which will record and playback anything pretty much doesn't matter what the tape actually is.
We have two of them and we use them for screening of international reels and to send out really really bad sample reels.
Real converters are called "Four Field" (or more) converters and read in two entire television frames of one standard and only then try to figure out where the picture parts should be for the output frames. It's not ususual for you to need an audio delay as well because you can see two-frame delay in lip sync. It's pretty heavy stuff.
For PAL/NTSC work, there are resolution problems one way and motion problems the other.
Our two VHS machines double up and drop video scan lines as needed to simulate a conversion. It looks pretty ratty; you can see it happening.
Most of the time the grandparents in Ireland watching the American Baby Caoilfhionn (pronounced "Keelin"
for the first time just don't care.
