Introduction
In this series of videos, we will be exploring the workflow of working with footage that has been pre-denoised by the firmware of your camera. We will be using Neat Video, a powerful noise reduction tool, to address noise, flicker, and compression issues. This tutorial will guide you step by step through the process, starting from understanding the challenges of pre-denoised footage to fine-tuning the filter settings for optimal results.
Understanding the Footage with Pre-Denoised Firmware
Before we dive into the noise reduction process, it is important to understand the characteristics of footage that has undergone pre-denoising by the camera's firmware. Even though the firmware attempts to reduce noise, there may still be residual noise present, along with flicker and compression artifacts. These issues can be tackled effectively using Neat Video.
Identifying Noise and Flicker Issues
To begin, we need to identify the noise and flicker issues in our footage. In the example provided, we have a clip from a GoPro camera with built-in denoising. However, even after the denoising, there is still noticeable noise, flicker, and jitter of details. These issues can disrupt the visual quality of the footage, but Neat Video can help in resolving them.
Using Neat Video for Noise Reduction
To start applying noise reduction to our footage, we need to locate Neat Video in the Effects Panel. Once found, we can drop the "Reduce Noise" version 5 effect onto the clip. This will open the Neat Video window, where we can begin the noise reduction process.
Selecting a Frame for Profiling
To build an accurate noise profile, we need to select a frame that best represents the noise and problems we want to combat. In the example clip, since the scene is static, any frame will do. However, it is recommended to choose a frame with strong noise, no details, and the presence of all the issues we want to address.
Building a Noise Profile
With the frame selected, we can now proceed to build a noise profile. Neat Video provides an auto profile feature that automatically selects an area with uniform noise. Once the profile is built, we can check its accuracy by using the profile check mode, which removes everything the filter sees as noise. This may make the image look plastic, but it is crucial to check if all the noise has been correctly detected.
Checking the Profile
After the profile check, we need to examine the frame at increased zoom levels, such as 200% to 400%, to ensure that no bits of noise are left. If there are still areas with residual noise, we can adjust the noise level slider to a higher value. In the provided example, the noise level was set to 95%, indicating that the original noise profile was not accurately captured due to the built-in noise reduction of the camera.
Using the Generic Profile
In cases where a noise profile cannot be accurately built or the noise has been heavily transformed by in-camera noise reduction or compression, Neat Video offers a generic profile feature. This feature is designed for situations where it is challenging to find large enough featureless areas for profiling. By experimenting with different generic noise settings, we can achieve satisfactory noise reduction results.
Comparing Results
It is essential to compare the results obtained from auto profiling and using the generic profile. In the provided example, it was evident that the generic profile was more effective in achieving accurate noise reduction without the need for manual adjustments. These results highlight the advantages of having control over in-camera noise reduction settings.
Tuning Filter Settings
After building the noise profile and selecting the appropriate profile Type, we can switch to the adjust and preview tab. Here, we can fine-tune the filter settings if necessary to achieve the desired level of noise reduction without sacrificing image quality. This step allows us to customize the noise reduction parameters Based on the specific requirements of the footage.
Conclusion
In conclusion, Neat Video is a powerful tool for reducing noise, flicker, and compression issues in footage that has already been pre-denoised by the camera's firmware. By following the steps outlined in this tutorial, You can effectively address these problems and enhance the visual quality of your videos. Experiment with different settings and profiles to achieve the best results for your specific footage.
