• Cinemetrics is thus “understood to mean the statistical analysis of quantitative data, descriptive of the structure and content of films that might be viewed as aspects of ‘style’. For practical purposes this usually means the analysis of data that describe shots in some way, for example their length or a characterization of their type. Shot lengths(SLs) have attracted most attention in the literature; examples of type includes classification by shot scale, content (e.g., action/dialogue), camera movement and so on” (Baxter, 2014, p.2).

Understanding Cinemetrics

Cinemetrics was originated from an eponymous website(www. Cinemetrics.lv) initiated by Yuri Tsivian, a professor from University of Chicago.

- The website introduces a data collection tool that works like a stopwatch that allows contributors to make annotation about the editing decision on films.

- At the same time, the website serves as a repository that displays a database of the quantified data about thousands of films (17,000, data collected till 2014) across history based on crowd collaboration. This website has attracted many scholars to do further studies by utilizing their data.

• Content analysis• Statistical analysis of quantitative data• Experiment

Basic Terminology about Video Editing

Shot Length• Shot lengths (SLs)• Average SL (ASL)• Median SL (MSL)

Shot Scale• Medium shot (MS)• Medium long shot (MLS)• Long shot (LS)• Very long shot (VLS)

Camera Movement• Big Close-up (BCU)• Close-up(CU)• Medium close-up (MC)

Frame Rate: The number of fames or images that are projected or displayed per second, usually represented as FPS, frame per second.

Shot: Between one cutting point to another cutting point in digital post-production editing decision list.

Motion: “motion is the optical change created by moving objects, people and shadows” (Cutting, et al, 2011, p.571) In this study, we use a motion indexwhich represents the percentage (value between 0.0 and 1.0) of how many pixels have significantly changed (difference above a certain threshold) from one frame to the next.

• “To establish the existence of an individual formal style in the work of director, it is necessary to compare not only a sufficient number of his film with each other, but also-which is always forgotten- to compare his films with films of similar genre made by other directors at the same time…..An even more absolute norm for any period is really needed as well, to give a standard of comparison that reflects the technical and other constraints on the work of filmmakers at that time and place…” (Salt, 1974, p.14)

• It is quantitative content analysis

• Usually examined through large data samples

What is film Style? Norm? Pattern? Does film also have pattern or norm?

Literature Review: pattern recognition, comparison, re-contextualization

Literature Review

Measured 160 English-language films released from 1935 to 2010 and found four linear changes:

• Shot lengths have gotten shorter

• More motions and movements in contemporary films than in earlier films

• Shorter shots also have proportionately more motion than longer shots, whereas there is no such relation in older films.

• Films have gotten darker; the mean luminance value of frames across the length of a film has decreased over time.

Cutting, J. E., Brunick, K. L., DeLong, J. E., Iricinschi, C., & Candan, A. (2011). Quicker, faster, darker: Changes in Hollywood film over 75 years. i-Perception, 2(6), 569.

*Notes: psychological effects associated with these four changes and suggest that all four linear trends have a single cause: Filmmakers have incrementally tried to exercise more control over the attention of filmgoers. We suggest these changes are signatures of the evolution of popular film; they do not reflect changes in film style.

H1: The average shot length of the movie trailers are decreasing overtime H2: The ratio of number of shot versus the shot length are increasing overtimeH3: The correlation coefficient of the shot length and motion index are significantly negativeH4: The correlation coefficient of the shot length and motion index are getting stronger overtimeH5: The luminance of the color is decreasing overtime

Research Hypothesis and Research Questions

RQ1: Does trailers’ editing pattern evolve over the past few decades?

RQ2: If the trailers editing pattern does evolve overtime, then does it align with the overall movies’ editing pattern evolution overtime – based on James Cutting’s study (2011) ?

Shots and Motions Correlation Coefficient Change Overtime

Correlation of Shots and Motions of Each Trailer Overtime

Correlation of Shots and Motions of Each Generation of Trailers Overtime

• The correlation coefficient of shots and motions are all negative, showing that shorter the shots are, the more motions there are

• However, the overall correlation coefficient is not significant, showing that the correlation doesn’t have too much variation over time which is not aligned with Cutting’s study
