Due to limitations in filming techniques and improper post-production handling at the time, many early films were shot on film, resulting in potential noise issues with the images. As time passes, incidents such as fading and scratches occur, contributing to an increase in image noise. Unlike old films, movies with less noise, higher definition, and more natural and harmonious colors are more in line with modern people's preferences. In this article, it will detail how to use AVCLabs Video Enhancer AI to reduce grain in old film footages.

Part 1: Why Old Films Always Carry Grain?

Old movies have noise, mainly due to shooting technology, storage media, and post-processing. The noise in old movies is the result of the combined effect of many factors.

👉️ Shooting technology limitations: Early movies were mostly shot on film, and the photosensitive materials on the film were arranged in disorder, which is different from the pixel array of modern digital cameras. This disorder itself can cause noise in the picture. In low light conditions or when the ISO is not set properly, the noise on the film will be more obvious.

👉️ Problems in the preservation process: Over time, the film may undergo physical or chemical changes, such as fading and scratching, which may increase the noise in the picture.

👉️ Impact during the digitization process: When converting old movies from film to digital format, if the scanning equipment is not advanced enough or the scanning parameters are set improperly, noise may also be generated.

👉️ Improper post-processing: During the film production and transmission process, if the image is over-sharpened or the details are enhanced, the noise may also become more obvious.

For the audience, this noise is sometimes regarded as a kind of "movie flavor", adding to the retro and artistic atmosphere of the film. However, as digital restoration technology matures, many classic old movies need careful digital restoration to reduce noise and improve image quality so that audiences can better appreciate these precious cultural heritages. So, how to use AI tools to denoise old movies?
