24 @ 25 The most common method of transferring film to PAL video, where the film is sped up during the telecine transfer to 25 fps. This creates a one-to-one film-to-video frame relationship, but speeds up the action by 4 percent. See also 24 & 1, 24 @ 25 pull-down. 24 @ 25 pull-down The Final Cut Pro term for the 24 & 1 method. See also 24 & 1, 24 @ 25. 24p A high definition video format using a 24 fps rate and progressively scanned video. It is finding wide use in film production because of its high quality and identical frame rate. It also converts easily to most 29.97 fps and 25 fps standard and high definition video formats. Acmade number See ink number . "A" frame The first frame in the repeating five-frame 3:2 pull-down sequence. In two-field 3:2 pull-down video, it is the only frame that fully contains both fields from a single film frame. B, C, and D frames have their fields split among two video frames. A frames normally occur on timecode numbers ending with "0" or "5" (when using non-drop frame timecode). See also 3:2 pull-down , field . ALE file Abbreviation for Avid Log Exchange. A file format that allows film databases to be shared between different systems. See also telecine log . answer print The first film print that includes sound and picture, submitted by the laboratory for the customer's approval. aspect ratio The ratio of an image's width to its height expressed either as two numbers (width:height) or as a value equal to the height divided by the width. Standard definition video uses 4:3 (0.75), and most high definition video uses 16:9 (0.56). Film aspect ratios depend on the format and lenses used. change list A list you can export from Final Cut Pro using Cinema Tools, which assumes a workprint or negative has been cut to the specifications of a cut list (or prior change list) and specifies further changes to make based on new edits you have made to a Final Cut Pro sequence. conform (film) To cut and arrange an original camera negative to match edits made in a digital editing system. Also, to assemble video or audio according to an Edit Decision List (EDL). See also cut list , Edit Decision List (EDL) . conform (video) To change the frame rate of a video clip. For example, you can use the Cinema Tools Conform feature to change the frame rate of a PAL 25 fps video clip to film's 24 fps rate. You can also conform a clip to its current frame rate, ensuring there are no frame rate errors within it. 250 Glossary
