I tried applying the processing with these settings and didn’t notice any difference, probably depends on the quality of the original video. Starlight Precise in addition to this defect makes many others that are found in each processed video - somewhere more, somewhere less... Processing takes several hours even on RTX5080, so I will upscale those videos that are interesting to me and that have not yet been made through Starlight. Unfortunately, Heartbreaker is not part of my plans.
That is unfortunate, and yes that is the biggest problem The process is time consuming and the results are random too, and no worries about Heartbreaker, when the process takes time and money it's best to focus on something you're interested in and want to do, but keep up the good work mate
