Category:Videos by technical criteria

This meta category should only contain other categories. Files should either be in the relevant subcategory or in the parent category.

This category organizes videos by technical criteria. A technical criterion is anything that can, at least in principle, be automatically determined. Examples are, dimensions, number and resolution of color/alpha channels, file type, existence of metadata, histogram properties (like monochromatic 24bit JPEGs, images with high or low contrast (as defnied in a technical sense), and so on. Ideally, this category and its subcategories will be automatically maintained.
