Alternatively, if the video contains a lot of motion, the bitrate needed for equivalent quality will increase. Instead, I would like to invite you to ask yourself about the quality required for each individual video usage.įor example, it is interesting to evaluate the necessary bitrate according to the abrupt changes presented in the video: the more fixed is the content, the less data you will need to allocate to each second of the video. I don’t have a magic formula to share that would compute the perfect bitrate. The more data you allocate per second, the better is the quality but the heavier is the file. What is the bitrate? To say it simply, bitrate is the amount of data needed to encode one second of video. Even if the file size seems small, it may be possible to improve the bitrate for an optimal diffusion. To optimize your video, you need to ask yourself how it delivers its content over the network. Making your pages unnecessarily heavy will not help your visitors. Keep in mind that some Internet Providers sell packages that are limited in total bandwidth. Reducing file weight: the right balance between quality and performanceĪ heavy video will cause an increase in the total page weight. VLC “Convert & Stream” interfaceĭisclaimer: the following examples will make intensive use of ffmpeg, one of the most popular video editing program among developers, but most of the optimizations should be available in your favorite software. There are a few things to be careful about. However, you don’t broadcast a video on the Internet like you do on a desktop computer. This format is supported by most video manipulation software: Handbrake, MPEG Streamclip, OpenShot… even VLC! But few of them offer a dedicated export for the Web. The most widely used and supported encoding is undoubtedly H.264, served by an MP4 file. But adding video to a site can be challenging. Whether you are a luxury player wishing to broadcast extremely high-quality videos or a news platform looking for an eye-catching proposal, video has become an essential part of the Web in just a few years. Source: HttpArchive through a BigQuery query. Usage evolution of the different video files types on the web. However, MP4 is often used improperly, which can have an unfortunate impact on the User Experience. Representing more than 75% of the videos served on the Internet, MP4 is the most commonly used format today.
