The first question to answer is: how many hours of analysis will be needed per day (or week, month)? As a 'worst case' scenario, if we assume that QScan can analyze at Real Time Speeds (that is true up to HD resolutions), 1 simple license of QScan (1 file at a time) would be capable of analyzing 24 hours of material in a day, thus the basic license consisting of 4 files at a time, will be capable of analyzing 96 hours per day, assuming 24x7 use, and that the HW and network are enough for those speeds. Taking this as the bottom line, the faster the machine, the bigger the amount of content that could be analyzed per day. So, if we aim at analyzing 125 hours of content per day, 125/24=5,21 files at a time (considering 24x7 operation). So, it would be necessary to analyze more than 5 files at a time. Thus needing additional worker nodes. NOTE: performance can vary depending on the Hardware, file formats, file bitrate, parameters to be analyzed, etc. Heavy file exchange formats (DNxHD, ProRes, XAVC, J2K, etc) might take longer than traditional broadcast formats (MPEG2, H264, HEVC, etc).
