- # Adobe After Effects Automatic Footage Interpretation
- #
- # lines beginning with "#" are comments
- #
- # basic format of a hard rule: {match requirements} = {set interpretation}
- # basic format of a soft rule: {match requirements} ~ {set interpretation}
- #
- # + for each rule that matches, the interpretation is set; wild-cards ("*") allowed
- # on both sides; wildcard match matches anything, wildcard set sets nothing
- # + multiple rules are allowed to match, later matches override earlier matches
- # + all rules are scanned in order, one rule per line
- # + rules are applied after pixel aspect ratio, alpha information, and field label
- # information is read from a file
- #
- # + soft rules will not override values that are specified explicitly by the file format
- #
- # width, height, frame-rate, file-type, codec =
- # pixel aspect ratio/name, field order, conform frame-rate, alpha interp
- #
- # width & height are integer numbers
- # frame-rate is a decimal number
- # file-type is four characters in quotes (4c's)
- # codec (applicable for QT & AVI only) is also 4c's
- #
- # to find out the file-type and/or codec 4c's for a specific type of footage,
- # opt-click (Mac) or alt-click (Windows) on the footage in the project window;
- # the 4c codes will appear in the last line of text by the thumbnail
- #
- # the pixel aspect ratio is a ratio of integers (e.g. 10/11)
- # optionally followed by a name for that ratio (e.g. 10/11/"My Aspect")
- # the field order is a single character, (F=frame, U=upper field, or L=lower field)
- # the conform frame-rate is a decimal number
- # alpha interp: (I=ignore, S=straight, P=premul/black, W=premul/white)
- # alpha interp is ignored for footage without an alpha channel
