The tape will pulled less than its standard length when a tension less than the standard tension is applied, making the tape too long. A tape stretches in an elastic manner until it reaches its elastic limit, when it will deform permanently and ruin the tape. The correction due to tension is given by:
Indonesian filmmakers have raised concerns regarding workplace safety for production crew on the opening panel at the inaugural JAFF Market, running Dec. 3-5 alongside the Jogja-Netpac Asian Film ...
However, this still left film shot at cinema frame rates as a problem. The obvious solution is to simply speed up the film to match the television frame rates, but this, at least in the case of NTSC, requires a change that is rather obvious to the eye and ear. The simple solution is to periodically play a selected frame twice.

Correction tape is sold in short spools for hand use, or as long rolls to be used in typewriters, which apply sudden pressure when a key is struck, and can therefore apply the masking material in exactly the same shape and position as the erroneous character. Some versions of correction tape are sold in separate dispensers that are used to roll ...
Presentation time stamps (PTS) are embedded in MPEG transport streams to precisely signal when each audio and video segment is to be presented and avoid AV-sync errors. . However, these timestamps are often added after the video undergoes frame synchronization, format conversion and preprocessing, and thus the lip sync errors created by these operations will not be corrected by the addition ...
The end product of the offline non-linear editing process is a frame-accurate edit decision list (EDL) which can be taken, together with the source tapes, to an online quality tape or film editing suite. The EDL is then read into an edit controller and used to create a replica of the offline edit by playing portions of the source tapes back at ...
