Initial Audio Workfl ow, Importing Production Audio, and Syncing<br />

is to say setting one to match the other. Now, any and all video cameras, recorders, and slates will<br />

show the same time code. When the sticks on the slate are closed, the time code changes to a reference<br />

stamp, which is often the date. This makes it easy to fi nd the frame where the sticks close and<br />

you can have a record of the time and date the shot was made.<br />

Because every device is soft locked to its own reference clock, micro clock errors will cause the<br />

devices to drift apart over time. All devices should be rejammed several times through the day to<br />

ensure they are all in sync with each other.<br />

Syncing is now much faster as the time code on the audio recorder can be matched to the number<br />

photographed onto the fi lm from the slate. Syncing can now be done in telecine as the fi lm is transferred.<br />

The audio time code is simply read from the slate and entered on a keypad in the telecine<br />

room. Some recorders do not record time code and can only be sunc to the clapper sticks after the<br />

telecine or transferred to time code DAT before telecine.<br />

In spite of having this photographic reference fi lmed or videotaped, many people still prefer to sync<br />

to the sticks close. Even though it is possible to only fi lm the time code on the slate, the sticks are<br />

still snapped shut. This serves several purposes even if you are planning to sync to the time code<br />

from the slate rather than the sticks. First, it’s a great backup. If something goes wrong and the time<br />

codes don’t match, or the slate is out of focus, then you can still sync to the sticks closing as long<br />

as it can be seen in the shot. Second, it confi rms that this is a sync shot and was not shot MOS<br />

(without sound). When shooting MOS, it is best practice to keep the sticks open with a hand through<br />

the opening blocking the sticks from closing to announce visually, this shot has no sound. Third,<br />

verbally calling the slate and snapping the sticks closed helps announce to everyone on set that the<br />

camera is running and sound is being recorded.<br />

The time code slate works well in a number of circumstances, especially when shooting live events<br />

with multicameras. Consider a fi ve-fi lm and one video camera shoot of a concert. One or even two<br />

time code DAT or other type of time code digital audio recorders can be fed from the stage audio<br />

mixer. One of the audio recorders can be jammed to the other and the video camera and fi ve slates<br />

can also be jammed to the same time code as the audio recorders. All audio, video, and slates will<br />

now show the exact same time code. The video shots can now be pulled into sync with the DAT<br />

audio with a simple “merge clip to time code” command in Final Cut Pro. (More on this later in this<br />

chapter.) As the time code of the video, audio, and slates are all the same format, probably 29.97 DF<br />

or NDF, the slate numbers will advance in sync with the video.<br />

The problem is not as straightforward with fi lm to be edited on digital video. In this case, the camera<br />

is rolling at 24 FPS, but the transferred video will be 29.97 and may be reversed to 23.98. Choosing<br />

the time code for the audio and the slate therefore becomes a problem. Often, the audio time code<br />

will be 30 DF or NDF, when this audio is pulled down the rate will be 29.97 DF or NDF. The video<br />

time code used in telecine will probably be 29.97 NDF, so this sounds like a good match. But because<br />

the camera is running at 24 FPS, the numbers on the slate will be advancing faster than the fi lm, and<br />

this will cause photographed numbers to be skipped and/or overprinted. Running the audio time code<br />

at 24 FPS is not much better; the 29.97 video will have repeated numbers and any reversed 23.98<br />

digital video may be overprinted.<br />

In Figure 3.3, the slate from Lost Hope and More, several problems can be seen. First, the slate time<br />

code numbers are overprinted. The frame number was 11 and advanced to 12 with the fi lm shutter<br />
