What Видео в MP3 does

Extracting audio means keeping only the sound track of a video. Видео в MP3 reads the video with FFmpeg, skips the picture and encodes the sound as MP3 with the LAME encoder. The audio is always re-encoded, even when the video already contains MP3 sound, so you can choose the bitrate. Because no video frames are encoded, this is much faster than converting a video.

It is useful when you only need the music, speech or interview from a recording, since a small MP3 is easier to store, play and share than the full video.

When to use Видео в MP3

• Save the audio of a recorded lecture, webinar or meeting as MP3 to listen to it on a phone while commuting.
• Take the song out of a music video you made, to share it on platforms that accept only audio files.
• Extract an interview from a camera recording so it can be transcribed or edited in an audio program.
• Keep the soundtrack of a family video as a small MP3 when the full video is too large to send.

Settings explained

Bitrate

Sets the MP3 bitrate from 64 to 320 kbps. The default of 192 kbps suits music, while 96 or 128 kbps suits speech and gives much smaller files. At 192 kbps and above, audio is saved at 44.1 kHz.

Mono

Mixes the sound into a single channel. Choose it for lectures, voice recordings and phone videos, where stereo adds nothing. Leave it off for music and films with stereo effects.

Format comparison

Какво е MP4?

MP4 (MPEG-4 Part 14) е формат за видео, представен през 2001 г. (разработчик: MPEG). Форматът използва компресия със загуби. Файловете са с разширение .mp4.

MP4 is a container format defined in part 14 of the MPEG-4 standard and based on Apple's QuickTime file format. It holds separate video, audio and subtitle tracks. The video is usually H.264 or H.265, sometimes AV1, and the audio is usually AAC. The codecs inside, not the container, decide the quality.

MP4 with H.264 video and AAC audio is the most compatible choice for sharing video. It works well for uploads to social media and video sites, playback on phones and TVs, and video embedded in websites.

Compatibility depends on the codecs inside. An MP4 with H.265 or AV1 video may not play on older devices or in every browser. H.264 and H.265 are patented codecs. Editing and saving again with a lossy codec reduces quality.

MP4 plays in all major web browsers, on Windows, macOS, Android and iOS, on smart TVs and game consoles, and in players such as VLC. H.264 MP4 is the safest choice when you do not know the device.

Какво е MOV?

MOV (QuickTime Movie) е формат за видео, представен през 1991 г. (разработчик: Apple). Форматът използва компресия със загуби. Файловете са с разширение .mov.

MOV is the QuickTime movie format created by Apple. It is a container with tracks for video, audio, timecode and text. The MP4 format was based on it, so the two are closely related. iPhones record MOV files, usually with H.264 or HEVC video, and professional workflows often use ProRes inside MOV.

MOV is a natural choice for video recorded on Apple devices and for editing in Final Cut Pro, iMovie and other professional tools. With codecs such as ProRes, it keeps high quality during editing and post-production.

MOV files with professional codecs are very large. Some Windows programs, Android devices, browsers and websites do not play MOV, especially when it contains HEVC or ProRes video. Converting to MP4 usually solves compatibility problems for sharing.

MOV plays natively on macOS and iOS in QuickTime Player and Photos. Windows can play many MOV files in its built-in apps or in VLC, depending on the codec. Safari plays MOV, while other browsers support it only partly.

Какво е AVI?

AVI (Audio Video Interleave) е формат за видео, представен през 1992 г. (разработчик: Microsoft). Форматът използва компресия със загуби. Файловете са с разширение .avi.

AVI is a container format introduced by Microsoft as part of Video for Windows. It is based on the RIFF file structure and stores audio and video data interleaved in chunks. It can hold many codecs, and in the 2000s it was often used with DivX or Xvid video and MP3 audio.

Today AVI is mainly useful for compatibility with older software, older hardware players and some industrial or scientific cameras. For most new videos, MP4 or MKV is a better choice.

AVI is an old format that handles modern codecs and features, such as variable frame rate and subtitles, poorly. Files are often larger than MP4 files at the same quality, and web browsers cannot play AVI.

Windows plays many AVI files in its built-in apps, depending on the codec. On macOS, Linux, Android and iOS, a player such as VLC is usually needed. Browsers cannot play AVI, although many video sites accept it as an upload.

Какво е WEBM?

WEBM (WebM) е формат за видео, представен през 2010 г. (разработчик: Google). Форматът използва компресия със загуби. Файловете са с разширение .webm.

WebM is an open, royalty-free video format started by Google for the web. It is based on the Matroska container and allows only a few codecs: VP8, VP9 or AV1 for video, and Vorbis or Opus for audio. This restriction makes playback in browsers predictable.

WebM is a good choice for video on websites, short clips with small file sizes, and screen recordings made in the browser. It can also store video with transparency, which an MP4 with H.264 video cannot.

Some older Apple devices, editing programs, TVs and phones cannot play WebM. Encoding VP9 or AV1 is slower than encoding H.264. Some social media sites and messaging apps convert or reject WebM uploads.

Chrome, Edge and Firefox play WebM on all platforms, and recent Safari versions support it on macOS and iOS. Android plays WebM natively. On Windows and macOS, VLC and most modern media players open it.

Защо да изберете FansBond: Видео в MP3

Файловете остават на устройството ви, което е по-безопасно за лични снимки, договори и непубликувани проекти, а често е и по-бързо, защото нищо не трябва да се качва или изтегля.

Няма опашки, водни знаци и акаунти. След като страницата се зареди, инструментът продължава да работи дори при бавна връзка.

Tips for the best result

• Use 128 kbps or lower for long speech recordings. A one-hour talk is about 58 MB at 128 kbps and about 29 MB at 64 kbps.
• The whole video file is loaded into the browser's memory. For very large videos, close other tabs first, especially on a phone.
• If you see a message that there is no audio track, play the original in a video player. Screen recordings and some exported clips are silent.
• To keep only part of the sound, shorten the video first with the trim tool, then extract the audio from the shorter clip.

How Видео в MP3 works in your browser

Video and audio are processed with FFmpeg, the open-source media toolkit behind most video software, compiled to WebAssembly. Video is encoded with H.264 for MP4, MOV and MKV, VP8 for WebM, and audio with AAC, MP3, Vorbis, Opus or FLAC depending on the format.

WebAssembly FFmpeg runs on your device's processor without a server. It is slower than a native desktop app, so a long video can take a few minutes. Keep the tab open until the progress bar finishes.

Privacy and security

Most online converters upload your files to a server, process them there and keep a copy for some time. Видео в MP3 works differently: the code is downloaded to your browser once, and your files are read and written only on your device.

You can check this yourself: after the page has loaded, turn off your internet connection and the tool still works. This makes it safe for contracts, IDs, medical records, private photos and unreleased work.
