In a broad sense, a clean set of images means keeping the extracted faces you want to swap, deleting unwanted faces extracted from the video clip and also deleting any extracted objects falsely identified as faces.
Was that in response to me? Not trying to be rude, but genuinely confused because it doesn't seem to be answering the question I was asking at all. Maybe I did a bad job explaining. From the top:
Sometimes I extract for conversion, in which case I extract every frame, and keep the alignments file, as the alignments file is what will be used for the conversion process.
Sometimes I extract for training, in which case I'll only extract every 10-15 frames, and discard the alignments file, because the training phase only makes use of the images, not the alignment files.
Sometimes I build a training set from images extracted from multiple videos, which means multiple extraction steps, followed by copy the contents of multiple image folders into one image folder.
The above Extract guide explains how to merge the alignment files from multiple extractions into a single alignment file, which only makes sense in the context of assembling a training set - you would never need to merge alignment files for a conversion, because conversions are done on single videos.
But if I'm not using the alignment file for training, then what need is there to merge them? Why bother merging alignment files into a single alignment file that you won't be using for anything?
It doesn't make sense, which to me is a red flag that I'm misunderstanding something potentially important.
