You can reduce the file’s resolution or data rate to help with this. If you’re uploading video content, you want to publish the best video quality possible at a size that’s accessible to the largest possible audience. While some large high-resolution files might play well on high-quality PCs, creators of video content also have to remember many people watch videos on smartphones, older PCs, or with slower Wi-Fi or cellular connections. But if you plan to host the video yourself or want it smaller to share the file more easily, reducing the size of video files is helpful for your audience. Most social sites like Facebook and YouTube will make your video smaller for playback across a variety of devices when you upload. Then, when you export, Media Encoder will automatically switch back to using your high-resolution sources. Compress video files to a more manageable format like MP4, helping make your workflow more efficient. You might create proxy files, which use a lower data rate but maintain the aspect ratio, for a smoother editing experience. Many video files, like those from a high-end camera, are large and can demand a lot from your machine while you edit, whether you work in Windows or on a Mac. Using Resi’s hardware or software encoders, broadcasters can have peace of mind that their videos will be delivered without any interruptions.If you are working with high-resolution source files, such as 4K video, reducing the file size of videos also saves time in production. Along with its hardware encoders, Resi also offers ProPresenter Stream, which is a software encoder that works with the broadcaster’s own hardware. Every bit of video is stored during each step of the capture and transmit process, so broadcasters won’t lose any content even during network outages. Resi offers multiple hardware encoders that are highly resilient. This helps ensure compatibility and optimal playback on a wide range of devices around the world. In fact, many broadcasters use cloud video transcoding to create multiple versions of a video with different formats, codecs, bitrates, resolutions, and more. Broadcasters choose one or more container formats depending on which video players their audiences use.Īlthough video files may be encoded into one format, transcoding software can convert video files into another format as well. The most popular container formats include WMV, MOV, and MP4. Once video files are compressed, they’re packaged into a video container format that includes the audio codec, video codec, closed captioning, and any other relevant metadata. While VBR encoding generally leads to better results, there are situations-such as live event streaming-where CBR may be necessary. Constant bitrate streaming (CBR) uses the same bitrate throughout the entire encoding process, while variable bitrate streaming (VBR) adjusts the bitrate dynamically based on the contents of the video. When encoding a particular video file, there are two common techniques video compressors use. Many broadcasters choose to encode their video content at multiple bitrates, and modern video players can use adaptive bitrate streaming (ABR) to adjust the video quality in real-time. Bitraterefers to the amount of data stored for one second of video, which means that lower bitrates usually correspond to a lower quality. The codec that broadcasters choose will depend on their budget, compatibility requirements, whether they’re live streaming, and many other factors.īesides the compression algorithm or codec itself, the bitrate is an important factor in the file size and quality of a video. Common video codec formats include H.264, H.265, AV1, and VP9. Codecs also convert raw video into a digital format that’s suitable for playback. Meanwhile, lossy compression removes noticeable detail from the video file, which could lead to pixelation or other perceivable degradations.Ī video codec- short for encoder and decoder-is the software necessary to both compress and decompress a video file. Compression algorithms that only remove redundant information like multiple identical frames without reducing the video quality are considered lossless. There are a number of video compression options that use different algorithms for choosing which data to eliminate. That’s why compressing video is crucial for over-the-top (OTT) streaming or delivering video content directly to viewers using the Internet. An uncompressed file can be hundreds of gigabytes in size, which would be prohibitively expensive to store or transfer. A video compressor is a software that reduces video file sizes by eliminating some data.
