I have a large collection of video files, which have missing atributes like length, resolution, bitrate etc. I would like to fill those out somehow but im not sure what solution to use. It would take ages by hand but i'd rather see if a program can do it first. I tried searching for a solution but didnt find anything substantial.
The reason why, is becuase im trying to filter out the videos by atributes. If a vid is shorter than 30 minutes, i delete it. Can sort with the windows explorer, which cant do that if the atributes are missing.
Since you asked this on StackOverflow and not on SuperUser I'm going to answer this as a programming question.
Those properties are provided by the Windows Property System. It is possible to write your own property provider and overwrite the system default provider registration but this is a fair amount of work if all you want to do is sort some files.
