It is recommended to check the requirements of all facilities involved in post-production prior to shooting.
Very often the camera is set to run at a different speed than the video system. In areas with NTSC video system for ex- ample, the film camera would run at 24 fps whereas the video system works with 30 full video frames per second. In order to adapt to specific needs there are two different time code formats possible.
To relate the time code count to the film camera, select the mode FRAME COUNTER FILM, which is often referred to as ”film-related time code”. In this mode, the frame counter of the time code (the last two digits of the time code display) is increased by 1 if the film is advanced by one frame e.g. 24 times a second at 24 fps. This makes it easy to identify one particular film frame by looking at the video image. However, this mode will create an unusual time code count because some video images are repeated to cope with the different frame rates of the video and the film camera. These repeated images will get duplicated time code words, which will create error messages on some time code readers.
To relate the time code count to the video system, select the mode FRAME COUNTER VIDEO. This is often referred to as ”video-related time code” . Every full video frame will ad-vance the time code by 1 e.g. 25 times a second in PAL or 30 times a second in NTSC. The IVS now creates a standard time code. However, it is more difficult to get the link back to the time code, which was recorded on film.
To get a reliable relation, it is necessary to utilize the Pull- Down (refer to chapter 6.8) or White-Line-Flag information (refer to chapter 6.11).
At every full second, both time counts are identical.
