Only process this many movies: Selects the first n movies to process, instead of processing the entire set. Helpful when working with a set of movies for the first time, to better understand the data quality.Low-memory mode: When working with very large movies on GPUs with low memory (less than, say, 16 GB), it is possible to run out of GPU memory. If this happens, turning on low-memory mode will usually allow the processing to proceed. This option makes processing slightly slower, so it is turned off by default. Output F-crop factor: Reduces the size of the output micrographs by "Fourier-cropping" (discarding Fourier components above a certain frequency). This reduces the size of the micrographs produced by the algorithm (which can speed up downstream processing), but also discards some of the highest frequency information in the images. This is particularly useful when dealing with super-resolution movies. An F-crop factor of 1.0 corresponds to no Fourier cropping, 0.5 discards half of the Fourier components, and so on.
