As far a i can tell there is no way to estimate the size of a video based on the output resolution, frame rate, and the various filters/enhancements. Can this be added so that we know how large the output file would be (approximately) prior to starting the “export”? Of course the size would vary based on the input file size, resolution, frame rate, etc. This would be very useful in determining which output resolution, frame rate, and filters to use. It allows for a much easier decision of quality vs. size.
