AB  - The paper presents the method and algorithms used to determine and reduce drift, wow and flutter in shrunken movie tapes. The idea behind the algorithms is to use image processing for calculating the local tape shrinkage which is one of the reasons for drift, wow and flutter. The shrinkage can be calculated via analyzing the image height of: a movie frame, sprocket hole, pitch or another standardized movie tape element; and then it can be expressed as the drift, wow and flutter characteristic. After the characteristic determination both the soundtrack and movie frames can be corrected. The paper presents the description of the image based drift, wow and flutter determination method and the experiments confirming the theoretical findings.
