....Keeping in mind that while "fps" is supposed to mean FRAMES per second, a frame is the same as a field in progressive scan, but it takes two fields to make up a frame in interlaced. However, many software and hardware manufacturers don't properly label this difference. So, if you are interlaced, one device may say 59.94, while another says 29.97, and they are the same thing. They really ought to - at the very least - use a capital F for frames and a lower case f for fields.
For example, to get Adobe Premiere to output a 1080 interlaced file playable on a Hyperdeck, you set your timeline to 1080i29.97 for the Hyperdeck to see 1080i59.94. So annoying that we can't have consistent standards for nomenclature. Adobe properly uses frames, while BMD uses fields for the same frame rate. Or, you could say they don't list frame rate, but field rate.
Or always do progressive, and you'll always be correct.
