I was just wondering if there was any way of resizing an alignments file, which was extracted at 4k, for use with a convert to 1080p? As far as I can tell the alignments generated from a 4k video should be more accurate than those at 1080, but converting a 4k video turns out to be a real pain, at least for my system. I don't know exactly how the alignments file stores the data, but if it stores coordinates for each point, wouldn't it be as simple as dividing each value by 2?
Thanks for reading.
