The Interopable Master Format (IMF) is the emerging standard for file based masters of audio visual content. Unravel is one of a small number of facilities in Australia that master to this format and can assist with the creation of IMPs (Interopable Master Packages) for service providers such as Netflix.

Fast Turn Around

From the time we have your master files and confirmation of the IMF specifications required, you're only looking at a 2-3 day turn around time.

Complimentary Quality Control Session

We aren't happy letting content go out without watching it ourselves to ensure it's exactly as it should be. As a result, we include a complimentary full QC pass in our price and also run your IMP through a validation process to ensure it's free of any technical problems.

File Specifications

Unravel prefers to work with file formats that will maintain the visual and auditory integrity of your content. This is especially true for IMF mastering since your packages will often be quality controlled by a service provider. It's therefore essential to ensure that the highest quality deliverable is supplied so that we can create a pristine master copy.
