Prelight is a new Mac OS X application designed to allow a Director of Photography (DoP) and other creatives to freely author, apply and modify looks. The commercial version, PreLight On-Set, extends these tools for the Digital Imaging Technician (DIT) for use during pre-production, production and post.

By installing this product, you are agreeing to partake in the Prelight On-Set Open Beta Programme. Prelight On-Set provides the full product functionality that you would need for use on production - including exporting 3D LUTs, support for driving LUT boxes and live SDI input - as well as, of course, all of the features provided with the free Prelight licence. For more information about the different levels of functionality available in Prelight versus Prelight On-Set, click here.


The beta licence for Prelight On-Set is a rolling 30-day licence. If, at the end of 30 days, the beta programme is still continuing, simply Activate the serial number again in the Prelight Licence window and a new licence will be issued.

When the beta programme is over, you will be able to visit our store to obtain the released versions of Prelight and Prelight On-Set.


At FilmLight, we pride ourselves on the responsiveness of our Support and R&D teams and we value your participation in our Open Beta Programme, which helps us to ensure that Prelight meets the needs of your projects and your teams so that you can achieve your goals.

If you find any issues during the beta period, have any questions about the product, or have any suggestions for enhancements, you can contact us via [email protected].

During the beta period, we may also send your surveys to complete about the product. We would appreciate you taking the time to provide us with feedback.
