Audio / Video Restoration

Quality check of released print
When we receive a movie, the first thing we do is check its physical conditions; if it is very old, we need to examine the state of all the sprocket holes and splices, so that film breakage will not occur during the subsequent washing and scanning process.

Chemical washing
Once the film is ready, we wash it in a specific machine to remove any impurities and dirt accumulated over the years, and then we run it through a special liquid to regenerate it.

Physical cleaning
Then we move on to the manual cleaning of the film which is carried out by physically running the film onto a special table that slowly unrolls it, while a technician specialized in film restoration cleans any damaged part, frame by frame, with special cleaning fluids and cloths. Everything is performed with the utmost care to avoid damaging or scratching the film.

Digitalization of positive film via telecinema
Depending on the customer’s needs, scanning could be done either via Cintel Ditto Technology (up to 4K resolution) or Arriscan technology (up to 8K resolution).
The audio print master, be it an optical or magnetic film, is also scanned using the best technologies and digital converters available, in order to be restored and corrected in the digital domain.

Digital Image Restoration
This is the longest phase of the restoration process.
As a software tool, we work with Diamant, by HS Arts, allowing the technician to work in manual, semiautomatic, or automatic mode.
The manual mode gives us the opportunity to work on the single frame, in order to eliminate and correct:

  • Artifacts, scratches, and spotting
  • Reduce noises and grains
  • Reconstruct damaged frames
  • Image stabilization

Digital Sound Restoration
Along with the process of Digital Image restoration, Digital Sound Restoration is performed. Once digitized, the audio track is handled with very specific softwares and technologies, such as Pro Tools HD Accel, and dedicated plug-ins like Izotope RX, Sonic No noise, Waves z-noise, and X-noise.
After the initial semiautomatic phase, we move on to manual correction: in this phase, we correct any clicks (high-frequency artifacts), glitches (scan artifacts), pops (low-frequency artifacts), and in general, any artifact produced by dust and dirt still present after washing. Then we perform the manual process of mixing in order to minimize background noise and eliminate most of the unwanted frequencies. Finally, if necessary, further editing is performed to the restored audio in order to improve lip and effects synchronization.

In order to guarantee a well-balanced sound in any type of environment, the digital sound restoration is performed using all of the following listening modes:

  • Professional headphones AKG
  • In small suite with near-field Blue Sky System One not equalized with X curve
  • In large cinema room with far-field Meyer Sound equalized with X-curve

Quality control (qc)
At the end of all the processes, we carry out a thorough Quality Control with a video and an audio operator, and if the results are considered satisfactory for the level of restoration required, we move on to mastering.

Once all the processes and the QC are completed, we move on to mastering the different formats required: TV/HOME VIDEO or D-Cinema.
