Tentacle Sync

A sneak peek into the future of smart timecode.

No one can deny it. Since the introduction of Tentacle Sync, our little octopus has changed the definition of how a timecode generator should be. Small, easy to use and smart.

But Tentacle Sync is not just a timecode generator – it is a complete, professional workflow solution. No matter if you are a youtuber or a feature film sound engineer, Tentacle Sync does the job.

And now we have taken that to the next level.




Accurate, small, lightweight and easy to use: You won’t want to work without Tentacles again.

With batteries lasting for up to 40 hours, an inaccuracy of less than 1 frame in 24 hours and a super-convenient UI, Tentacles are true “set and forget” devices.


The small, lightweight and unobtrusive Tentacles work with virtually all cameras and recorders on the market and bring timecode technology to any set.


As a producer, your job is to provide your crew with a streamlined production environment. So why not try a simple, cost-efficient workflow solution?


Tentacle Sync makes teamwork more fluid than ever while minimizing the risk of delays in post-production – saving you time and money. A perfect solution for all budgets.


The Tentacle Sync software prepares your material for editing within a glimpse. Just throw your clips in and that’s it!


Tentacle Sync allows you to read and analyze all kind of timecodes, including audio timecode, and enables you to sync, view and export dailies immediately – faster and more reliable than other software solutions.



Tentacles can be seen as accurate clocks, all running the exact same time. Connected to each camera or audio recorder, this time information will be recorded into the files of that recording device. In postproduction you can easily make use of that information to synchronize audio and video files which have been recorded at the same time.

Since this method is based on precise digital timing information and does not rely on shaky audio tracks, it works 100% and can be synchronized much faster than with pure software solutions.


Before shooting starts, you synchronize Tentacles by connecting them via cable, so that every Tentacle runs exactly the same time. The setup of the device works super-convenient either via laptop or smartphone. 



From a DSLR to an Arri Alexa, Tentacle works with all of them. Use as many Tentacles as you need.
To connect Tentacle to different devices, we offer a wide range on specific adapter cables. 



Timecode itself does not synchronize your material, it only makes it possible. For this task we have invented Tentacle Sync Studio (macOS)

Just throw your clips in and that’s it. Tentacle Sync Studio automatically synchronizes video and audio via timecode. It enables you to sync, view and export dailies immediately with almost no effort!

We are both cameramen who have been working in the film sector for many years. We filmed with all kind of cameras and also edited some of our projects. Our experience was that syncing can be a real pain – especially when using DSLR cameras or other semi-professional equipment. We thought there must be an affordable professional technical solution for this problem. But so far there was none. So we decided to change this. 

When we realized that this worked flawlessly, we thought that Tentacle could actually be a really helpful tool for others too. Over the last two years we and a lot of our friends and colleagues tested the Tentacles and the software in all kinds of settings: From student film to international high-end commercials, from rough documentary settings to TV multicam studio productions. 

Whenever we thought of a way to improve it, we got on it and found a solution. And now, Tentacle Sync is ready for market. We hope you love it!
