Final Considerations

4K videos are quite heavy to manage, so make sure your system has the resources to handle video processing. This is equally true of browser-based utilities because a browser's cache is limited, which may slow down the process. For best results, use applications like iMyFone Filme on computers that have medium to high specifications.

Additionally, you can also download files in a lower resolution if you're only interested in taking the audio portion. The audio sample rate is usually the same for different resolutions of the same video so you won't be losing any quality.

Finally, try not to use the computer for any concurrent tasks such as downloading files, processing images, and so on. This will put less pressure on your memory and storage so your video can be processed that much faster.
