I decided I wanted to objectively determine what the real sweet spot is for balancing resolution and compression artifacts. I used AviSynth's Compare filter to measure how much each video varying resolutions deviated from the original. Interestingly enough, the results I got showed that the more resolution (despite the more artifacting) was closer to the original. However, I find this difficult to accept. It is my personal opinion, and the recommended/default action of various automatic video encoders, that retaining maximum resolution for ~ 2hr video at 700MB is almost never the best choice.
So I'm wondering if anyone could confirm these results to see if I made a mistake somewhere. Or, maybe, is compare not the proper tool to use for this situation?
