Meet Matchbox / by CinoTracFor people who work with real film

Digital sound
for analog film.

Record digital sound in sync with your analog Super8 or 16mm camera — even when the camera itself has no sound recording. Meet Matchbox, by CinoTrac.

Physical frames. Digital possibilities.
A small box.
A bigger soundtrack.

Your Super8 or 16mm camera.
Now with synced digital sound.

A silent camera does not have to mean a silent film. Matchbox records digital audio alongside your analog Super8 or 16mm camera, using sync pulses to link the sound to the film’s movement.

Record directly into Matchbox with a microphone, or use your own field recorder linked to Matchbox through LTC/SMPTE timecode. Our companion application MatchboxSync brings externally recorded audio into sync with the film. The camera’s flash-sync connector supplies the primary frame reference; other pulse systems use a suitable interface.

From the first take to a digital scan — or a real film projection.
The Matchbox workflow

From the camera
to the screen.

Record with the camera. Bring synchronized sound to your digital film scan, your video edit or your projector.

01 / SHOOT

Record with the film.

Capture audio directly with Matchbox, even with a silent Super8 or 16mm camera. Or record on your own field recorder, linked to Matchbox through LTC/SMPTE timecode. Camera pulses connect the sound to the film’s movement.

02 / SCAN & EDIT

Bring sound to your scan.

Use Matchbox recordings or bring field-recorder and iPhone audio into sync with MatchboxSync. Supply the synchronized audio for a digital scan of your film, or place it under the scanned footage yourself in a video editing program.

03 / PROJECT

Let the projector lead.

Play your Matchbox recordings or an external soundtrack synchronized with MatchboxSync. Frame pulses from a compatible projector guide playback; preview audio, step through frames and adjust the alignment.

Your audio recorder.
Your film.
In sync.

Matchbox captures the film’s timing. MatchboxSync brings your externally recorded audio into sync with it.

Field recorder / iPhoneMatchbox timing referenceMatchboxSync

Record sound on your own field recorder, or on an iPhone using a Tentacle Sync E™ and the Tentacle Recorder app. Matchbox links the shared LTC/SMPTE timecode to the camera’s frame pulses.

MatchboxSync — our application currently known as super8sync — combines that timing reference with your external audio recording to produce audio synchronized to the film. Choose the recorder that suits you, then bring the sound back to your film.

Digital film scan

Supply the synchronized soundtrack alongside your film for the scanning workflow.

Video editing

Place the synchronized audio under your scanned footage in your editing program.

Film projection

Use the synchronized soundtrack with Matchbox and a compatible pulse-connected projector.

One Matchbox. Different workflows.

Before you connect

A few good
questions.

Does my camera need built-in sound?

No. Use a microphone connected to Matchbox, or a timecode-linked field recorder, to capture the sound separately. Your camera needs a supported sync-pulse connection. On suitable sound cameras, the monitor output can also serve as an audio source.

How does Matchbox follow the film?

The core workflow uses frame pulses from the camera or projector. These provide a reference to the film's movement, linking the recorded or played audio to physical frames.

Will it work with my camera or projector?

The primary camera connection is the flash-sync connector on compatible Super8 or 16mm cameras. Other sync systems, including 1,000 Hz pulse systems and projector interfaces such as Elmo ESS, require suitable interfaces. The required connection depends on the model; confirmed equipment and connection guides will be documented.

What is MatchboxSync?

MatchboxSync is our companion application, currently known as super8sync. It combines audio recorded on an external field recorder or iPhone with the timing reference captured by Matchbox, bringing the external recording into sync with the film. The synchronized audio can then be used for a digital film scan, in a video editing program or for soundtrack playback with Matchbox during projection. Explore the MatchboxSync workflow.

Can I use the audio in my editing software?

Yes. Using synchronized audio with a digital film scan is a central workflow. For external field-recorder or iPhone recordings, MatchboxSync brings the audio into sync using the timing reference captured by Matchbox. Supply the synchronized soundtrack for the scanning process, or import it alongside the scanned footage and place it under your film in a video editing program. Matchbox recordings use WAV/BWF files, with frame information kept alongside the audio.

What about timecode?

Matchbox already includes an implemented LTC Slave mode. It links LTC/SMPTE timecode to the camera’s frame pulses, so audio recorded on a compatible external field recorder can be brought into sync with the film.

You can also use an iPhone as your audio recorder with a Tentacle Sync E™ and the Tentacle Recorder app (Timecode Audio Recorder). The app receives timecode from the Tentacle via Bluetooth and embeds it in the recorded audio files. Matchbox receives the same timecode through the Tentacle’s wired LTC output while also recording the camera’s sync pulses.

The shared timecode connects the audio timeline to the film’s physical frame reference. MatchboxSync uses that reference to synchronize the external recording. You can then use the synchronized audio with a digital film scan, in your video editing program or in the projector workflow.

Keep shooting film.
