Click on the uploading button, then in the window that opens, select those files in MP4 format that you want to convert.
Now you can start converting your video right away. In some cases, you will also be able to adjust the conversion options.
Congratulations on your successful conversion. Now you can download a new file or several files to your device and check it.
Converting one file format to another may be necessary for various reasons. So, for example, you may want to convert MP4 to OPUS if your computer, phone or other device does not support MP4 format. Also, conversion is often required to reduce the file size, since the original format takes up too much space in the device's memory. Perhaps you just need to extract the audio track from the video file, in which case converting the video to audio format is a good option. In any case, with the help of our converter, you can easily complete the required task. Below you can find out some details about the original and new file formats.
While most of us only watch videos or movies almost every day, few are interested in formats. Typically, each operating system or software has its own formats, but some of them, such as MP4, are universal, making them much easier to distribute and use. MP4 file can contain video, audio, graphics and subtitles. Typically, a file with this extension is a video, movie, or other video. The MP4 format is widely used for video transmission over the Internet and distribution of mobile media content. The MP4 format is an add-on plug-in to MPEG4, which is a standard for storing encoded multimedia content (sound files, video content, etc.). In fact, MP4 is a technical specification, the requirements for which are established in the international standard ISO 14496-1. The most popular media format these days is MP4. Usually the built-in video player is enough to open it, but users often resort to additional software. The format allows for streaming over the Internet. In this case, data containing information necessary for broadcasting is transmitted along with the file. MP4 is one of the new standards in the world for digital coding of video and audio information. This format serves as a container for various types of audio and video streams (i.e. it does not include any information compression algorithms).
The main advantages of OPUS are high audio quality and good compression achieved through dynamic adaptive streaming. The format is based on technologies and broadcast algorithms from Skype and Xiph.org (SILK and CELT codecs, respectively). OPUS is the main audio codec in Skype today. Opus' structure allows it to effectively deal with sound artifacts. For this, a multi-stage audio signal processing architecture has been proposed. The main argument that speaks in favor of using the new codec for IP telephony is low time delay. The Opus codec is used for Voice over IP (VoIP), video conferencing, in-game chat. The Opus format has been standardized by the IETF and is maintained by Xiph.Org. Audio file encoded using the Ogg Opus lossy encoding format. The Opus format is designed for Internet audio streaming, that is, the transmission of sound over the Internet. The main advantages of the codec are low encoding latency (from 2.5 to 60 ms) and its high speed, a very high compression ratio of audio data with a very decent sound quality, support for multichannel audio (up to 255 channels). Opus is a completely open source, royalty-free, highly versatile audio codec. Opus is good for streaming both speech and music over the Internet. It's also great for storage and streaming.
