When converting MP4 files to Opus, there are several tips that can help you get the best results:

- Use the highest possible bitrate: Opus can provide high-quality sound even at low bitrates, but using a higher bitrate can result in even better quality. Aim for a bitrate of at least 128 kbps, or higher if you have the bandwidth and storage space.

- Choose the right sample rate: Opus supports a range of sample rates, from 8 kHz to 48 kHz. For most applications, a sample rate of 44.1 kHz or 48 kHz is recommended, as it provides high-quality sound and is compatible with most devices.

- Test different settings: Different applications and devices may have different requirements for Opus files, so it's a good idea to test different settings to find the optimal balance between quality and compatibility.

- Consider file size: Opus can provide high-quality sound with a relatively small file size, but keep in mind that higher bitrates and sample rates will result in larger files. Consider the storage and bandwidth limitations of your target devices and applications when choosing the right settings for your Opus files.

Converting MP4 to Opus can be done easily using the dedicated software and online tool introduced in the article. The choice of method will depend on your preference and the tools you have available on your device. Compared with the online solution, desktop software is undoubtedly more convenient if you are looking to process multiple files. It is important to remember to choose the appropriate quality settings. This will ensure that the output Opus files meet your needs and are of high quality.
