What is a Slate Call?

A slate call, also known as a clapperboard or simply a slate, is a filmmaking tool used to synchronize audio and video recordings. It's a small board with a hinged arm that's slammed shut before each take. This creates an audible "clap" that's easily identified in post-production. The slate also displays crucial information for the editing process. Mastering its use is essential for any filmmaker.

Setting Up Your Slate

Before you even think about using your slate, it’s important to correctly set it up.

1. Scene and Take Information

The most important part of using a slate is accurately filling in the scene and take information. Make sure you have the following information:

Production Name: The name of your film or project.
Scene: The scene number.
Take: The take number (e.g., Take 1, Take 2).
Date: The date of filming.
Roll: The roll number of the film or the camera's recording segment.

Ensure this information is clearly written and visible in the camera's frame.

2. Camera Placement

Position the slate clearly in the frame, typically in the lower left or lower right corner. Avoid obstructing important action. The slate should be easily visible but not distracting.

3. Lighting and Focus

Make sure the slate is well-lit and in focus. A blurry slate will make it difficult to sync audio and video later. Consider using a light source to illuminate it if needed.

Different Slate Call Techniques

There are a few different ways to use a slate call, depending on the situation.

1. The Standard Slate Call

This is the most common method. The first assistant director (AD) or someone designated for this task will:

Place the Slate: Position the slate clearly in the camera's frame.
Fill in information: Confirm all relevant information is accurate.
Clap the Slate: Sharply close the hinged arm, creating a distinct clap.
Hold the Slate: Hold the slate still for a second or two, allowing the camera to record the information.
Remove the Slate: Carefully remove the slate from the shot.

2. The "Silent" Slate Call

Sometimes, there might be unwanted sound in the background that makes the clap sound difficult to use later. In these situations, a silent slate can be used. This involves all the usual steps, except for the clap. The slate is simply held in place, showing the information to the camera. Synchronization in post-production will rely solely on the visual information.

3. The Digital Slate/App

Many filmmakers are now using digital slates or smartphone apps. These offer the advantage of automatically timestamping your shots. This makes syncing your audio and video far simpler during post-production. Many of these apps also provide other useful information such as scene number, take number, and more. They reduce room for human error and can streamline the entire workflow.

Common Mistakes to Avoid

Forgetting information: Ensure all information is correctly filled in before each take.
Not clapping hard enough: A clear, loud clap is crucial for accurate synchronization.
Obstructing the shot: Position the slate carefully to avoid blocking important action.
Poor lighting or focus: Ensure the slate is well-lit and in focus.

Conclusion

Mastering the slate call is a crucial skill for any filmmaker. By following these steps and avoiding common mistakes, you can ensure smooth post-production, prevent delays, and create high-quality films. Remember to always double-check your information and practice your technique to perfect the process. Using a slate properly is a key element in professional filmmaking, leading to better organization and efficiency.
