The Clapperboard Explained — How to Use a Film Slate

Key Points from the Video: 

Topic: Introduction
– The video is about how to use a slate in film production.- Knowing when to come into the scene to mark the slate is the first step, followed by listening for the first ad or director to call out your name.- Once you step in front of the camera with the slate, hold it up and say, “Scene ten Alpha, take one. Mark it.”- Marking a slate is easy once you know when and how to do it.
Topic: What is a Slate?
– The slate is a basic tool used on any film set.- It has a white balance bar, production name, role, scene and take number, director’s name, camera/DP’s name, date, and other details related to production.- The slate is used to help filmmakers keep track of various details and maintain consistency in production.- Code names are used for different letters to avoid confusion between letters and numbers.- A is referred to as Alpha, B as Bravo, and C as Charlie.
Topic: Soft Sticks
– Soft sticks are used during close up or emotional scenes to avoid disturbing the actor’s performance.- They are called softly and used especially when the slate is close to the actor’s face.
Topic: Tail Slating
– Tail slating will be the next topic of discussion.- When the director calls cut, yell out Tail slate to keep recording.- Hop into the camera frame, ensure focus, flip board upside down and say mark, mentioning scene number and take number.
Topic: MoS
– MoS means no audio for a scene.- Use a slate to indicate MoS by circling it and holding the slate with hands between the clapper.- For the first camera or Camera A, make sure the slate is in frame.- Mark the first camera with scene and take info, and for the other cameras, use Camera B mark or Camera C mark.- Role, scene, and take are three main things to know.- Role refers to the card number, and multiple cards might be used during an extended shoot, so it’s important to write them down.
Topic: Conclusion
– Use Gaffers tape to cover main areas that won’t change during the production and write down those areas to ensure they don’t change.

A. Evolution of Clapperboards

Clapperboards have been a crucial part of filmmaking since the earliest days of the craft. The device aided in the synchronization of picture and sound and helped to designate and mark various scenes and takes.

The device has evolved over the years, from early slate boards, to wooden clapperboards, to digital clapperboards that can change and display all relevant information digitally.

Despite the rise of technology, clapperboards remain a critical tool for filmmakers to ensure accurate synchronization, help in post-production editing, and establish continuity in their projects.

B. Contribution of Clapperboard in Modern Cinema

Even in today’s digital age, the clapperboard remains an essential tool in modern cinema and video production. Digital clapperboards can now display information electronically and can even sync with the camera’s internal clock.

However, the basic function of the clapperboard remains the same: to synchronize picture and sound and mark each take accurately.

Using a clapperboard can save valuable time in post-production editing and ensures continuity in a film’s storyline. 

A. Manual Clapperboards

Manual clapperboards are an indispensable tool for filmmakers and have been used since the early days of cinema.

They consist of a wooden or plastic slate with hinged clapper sticks attached to it.

The clapper sticks are snapped together to create a visual and audible cue for later synchronization in post-production.

They provide accuracy and continuity to the filmmaking process, allowing for easier editing and post-production. As technology advances, manual clapperboards remain an essential part of a film production team’s toolkit. 

Correctly Marking the Clapperboard

Correctly marking the clapperboard is crucial to ensure accurate synchronization of audio and video during post-production. Each space on the film clapper corresponds to the script supervisor’s report, so it’s important to check with him or her before marking any space.

The information on the slate, such as roll number and take number, is used for organizing footage.

Always mark the slate for A camera for consistency’s sake, and consider marking the audio file if you won’t have dailies.

Following proper clapperboard techniques can make post-production process smoother and more efficient. 

B. Digital Clapperboards

In modern filmmaking, digital clapperboards have become more common. These clapperboards include an electronic box that displays timecode information continuously on a LED display.

The timecode displayed on the clapperboard is synced with the internal clock of the camera, making it easier for the film editor to pull timecode metadata from the video and audio files and synchronize them.

However, even with electronic timecodes, the traditional clapper sticks are still closed together manually to ensure there is a way of manually synchronizing the footage and audio if matching the digital timecode fails.

Tail Slate

Tail slate is a technique where a clapperboard is used at the end of a take instead of the beginning.

This method is not as common and is usually reserved for situations when the actors need to focus on their performance or when the camera movement or focus cannot be adjusted to capture the slate at the beginning.

In modern filmmaking, digital clapperboards can be used to change and display all relevant information digitally, making it easier for post-production editing. 

A. Guide to Clap the Board

To properly clap the board, the clapperboard operator must present it in clear view and focus for a moment or two before striking the sticks.

The sound should be loud and sharp to ensure accurate synchronization.

When using a clapperboard, it’s important to keep track of scenes and takes to establish continuity.

By following proper clapperboard techniques, filmmakers can ensure a smooth post-production phase and make editing and organizing footage more manageable. 

Keeping track of scenes and takes

Keeping track of scenes and takes is crucial in filmmaking, which is why clapperboards are often used on set.
