Step-by-Step: Using Generative AI for Film Restoration (2025)

By /

Film restoration is a critical process in preserving cinematic history, allowing future generations to experience classic films as they were originally intended. With the advent of generative AI, the restoration process has been revolutionized, providing a powerful tool for restoring old and damaged film footage. In this article, we’ll explore a step-by-step guide on using Generative AI for film restoration as of 2025.

Introduction to Generative AI

Generative AI refers to the subset of artificial intelligence that focuses on generating new content, whether it be images, videos, text, or audio. This is achieved through machine learning models that have been trained on vast datasets to create outputs that are similar but not identical to the original input. In the context of film restoration, generative AI can be used to repair damaged frames, fill in missing information, and enhance the quality of both the visuals and audio of a film. For an in-depth understanding of Generative AI, the Wikipedia page on Generative Adversarial Networks (GANs) provides valuable information.

Preparing for Restoration

Assessing the Film’s Condition

Before starting the restoration process, it is crucial to assess the condition of the film. Check for common issues like scratches, dust, fading, and other forms of deterioration. This will help you understand the extent of restoration required and plan accordingly.

Digitizing the Film

If the film is not already in a digital format, it needs to be digitized. Use a high-quality film scanner to convert the film into a digital file. Ensure the scanner is set to capture at the highest resolution possible to retain as much detail as possible for the AI to work with.

Cleaning the Digital Scan

Even after digitization, the film may have artifacts like dust or hair. Use software to clean up these minor issues before employing generative AI. This step ensures that the AI focuses on more significant restoration tasks.

Selecting the Right Generative AI Tool

There are several generative AI tools available for film restoration, each with its strengths and use cases. Research and select a tool that suits your specific needs. Consider factors such as ease of use, cost, compatibility with your hardware, and the level of community and developer support. A popular choice as of 2025 is the DeepAI Film Restoration Suite, known for its robust features and user-friendly interface.

Restoring the Visuals

Frame-by-Frame Restoration

Use the generative AI tool to analyze and restore each frame of the film. The AI will detect and repair common issues like tears, folds, and missing fragments. Here’s a high-level overview of how this might be done:


Assuming the use of a CLI-based generative AI tool
Replace 'input' with the path to your input frames and 'output' with the desired output path
$ generativeai restore --input /path/to/frames --output /path/to/restored_frames

Enhancing Image Quality

Once the frames are restored, you can enhance the image quality. This might include increasing resolution, adjusting contrast, and improving colorization. The generative AI can be trained or might come with pre-trained models specifically designed for these tasks:


Example command to enhance image quality
$ generativeai enhance --input /path/to/restored_frames --output /path/to/enhanced_frames

Reviewing and Refining

After the AI has processed the frames, review them to ensure the restoration meets your standards. If certain frames require further attention, refine them individually using the AI tool or other software if necessary.

Restoring the Audio

Cleaning the Audio Track

Just as with the visuals, the audio track of a film can suffer from degradation over time. Use the generative AI tool to remove hisses, pops, and other forms of noise. The AI can also help to rebalance the audio levels and enhance clarity:


Example command to clean the audio track
$ generativeai clean_audio --input /path/to/audio --output /path/to/cleaned_audio

Syncing Audio with Video

It’s essential to ensure that the restored audio is in sync with the video. Use video editing software to align the audio and video tracks. Some generative AI tools might also offer features to automate this process:


Example command to sync audio with video
$ generativeai sync_audio --input_video /path/to/video --input_audio /path/to/cleaned_audio --output /path/to/final_video

Finalizing and Output

Assembling the Restored Film

Once all frames and the audio track have been restored and enhanced, assemble the film using video editing software. Ensure the transitions between frames are smooth and that the audio is properly synced throughout the entire film.

Exporting the Restored Film

Export the restored film in a high-quality digital format that preserves the enhancements made during the restoration process. Choose a format that is widely supported and suitable for archival purposes. For guidance on the best formats for film preservation, the Film Preservation Society offers valuable resources.

Troubleshooting Common Issues

During film restoration, you may encounter various issues. Here are some common problems and how to troubleshoot them:

  • AI Overcorrection: Sometimes, AI can overcorrect certain frames, leading to an unnatural look. If this happens, manually adjust the settings or refine the frame using secondary software.
  • Sync Issues: If audio and video are out of sync, try re-exporting the tracks or manually adjusting the timing in your video editing software.
  • Artifacting: AI restoration might introduce artifacts. Reduce the likelihood of this by using high-resolution scans and by adjusting the AI’s parameters for a more conservative restoration.

Tips for Successful Film Restoration

Here are some tips to ensure a successful film restoration project:

  • Always work with the highest quality scan possible to give the AI the best chance of accurately restoring the film.
  • Regularly save your work and create backups. Restoration is a time-consuming process, and losing progress can be costly.
  • Stay patient and allow time for manual adjustments. AI can do a lot, but it’s not perfect.
  • Keep the film’s original context in mind. Restoration should aim to preserve the director’s original vision.
  • Engage with the community. Forums and user groups can be invaluable resources for tips and troubleshooting advice.

Film restoration using generative AI is a cutting-edge process that combines technology with the art of cinema preservation. By following this step-by-step guide and staying aware of potential pitfalls, you can breathe new life into classic films, making them accessible and enjoyable for audiences now and in the future.
