When you rip video from a DVD and the dimensions are 720x480, is it best to encode that video to the same aspect ratio or change it to 640x480? I've asked different people and always get different answers.
To me, it makes sense to keep the encoded material exactly the same as the source... but I guess there is some mathematical equation thingie that I'm not considering.
I've also been told to "squish" the screengrabs down to 640x480 when taking them from a 720x480 source.
As you can see, I'm totally confused. My goal is to take ripped DVD material and encode it in the highest possible quality.
am I missing something?
thanks,
marc
