In these shutters, although each part of the film is exposed for the rated exposure time, the film is exposed by a slit which moves across the film in a time (the "X-sync speed") of the order of 1/100"; although the exposure of each part of the film may be 1/2000", the last part of the film is exposed later by the X-sync time than the first ...
The camera interface's parallel interface consists of the following lines: 8 to 12 bits parallel data line These are parallel data lines that carry pixel data. The data transmitted on these lines change with every Pixel Clock (PCLK). Horizontal Sync (HSYNC) This is a special signal that goes from the camera sensor or ISP to the camera interface ...
In video, frame synchronization is the process of synchronizing display pixel scanning to a synchronization source. When several systems are connected, a synchronization signal is fed from the synchronization source to the other systems in the network, and the video signals are synchronized with each other.
The AV-sync delay is static but can vary with the individual clip. Video editing effects can delay video causing it to lag the audio. Transmission (broadcasting), reception and playback that can get introduce AV-sync errors. A video camera with built-in microphones or line-in may not delay sound and video paths by the same amount.
MOS/sync – Sync-sound cameras are able to both maintain a constant speed (usually crystal lock) and run quietly enough not to be heard by the sound recordist. MOS cameras do not meet either one or both of these requirements, and are usually used either for applications where camera noise is not a concern, or non-standard camera speeds are ...
The then popular Mitchell camera, which could be operated silently made it possible to shoot in sync sound. However, due to the change of shooting environments from studios to locations, as well as the surging popularity of the more portable but noisy Arri 2c camera, [10] shooting with sync sound became less common during the mid 60s.
