Original Abstract

In the modern digital cinema production, extremely large volumes (in order of 10s of TB) of footage data are captured every day. The process of cataloging and reviewing such footage is nowadays largely manual and time consuming process. In our work, we aim at technical quality aspects, such as correct exposure, color compatibility of adjacent shots, and focusing. The main goal is to assist the reviewing process by providing shot quality meta-data and possibly ordering or even culling significant portion of the data from the review, as better quality shot of the same scene exists. However, in order to meaningfully compare technical quality, temporal shot synchronization needs to be performed first. We propose a fast and robust method for time synchronization of video sequences, capturing similar scenes, which arise naturally in digital cinema production. The method is tested on an extensive library of sequences and its performance is evaluated. We further present a preview of application of the proposed method to detecting focusing errors.
