Lower the Audio BitrateĪudio tracks are appended to video files. Other common codecs are AVI, WMA, XviD, Real Audio, and Apple Video. The most popular lossless codec is H.264, which preserves HD quality. Many videos on YouTube work well with a resolution of 360p, although there is support for HD. YouTube offers on the spot video compression, giving you the choice to adjust the resolution from the video player. The lower the resolution, the smaller your file. Try to keep your videos as brief as possible and cut out any unnecessary parts during the editing process. Many how-to sites like to break tutorials into Part 1, Part 2, etc. If you have a long video, you may want to cut it into segments to reduce loading time. The way you do this will vary based on the circumstances. The majority of post-production methods to reduce video size will take place during encoding. The ratio of size to quality is largely determined by compression, which is determined by format specifications. The following methods will help you reduce video size without rendering your videos unwatchable. The charts below show common bitrates for Standard Dynamic Range (SDR), High Dynamic Range (HDR), and audio bitrates. Expressed in kilobytes per second Kbps, a lower bitrate means a lower file size. Higher quality files have a higher bitrate. BitrateĪlso known as “data rate,” the bitrate controls the file size. It’s expressed in frames per second (FPS). The frequency at which separate images (frames) are displayed. Below are some common display resolutions for digital devices. So a resolution of 1366×768 means that there are 768 horizontal lines, each 1366 pixels wide. The smaller the resolution, the smaller your file size. The resolution describes the number of horizontal lines your video file has in each frame. There are thousands of different codecs in circulation, many of which are patent protected. The codecs used to compress the video file will determine the ratio of quality to file size. Codecs use different compression algorithms to encode files.

A codec is a software tool used to compress or decompress a video. CodecĬodec stands for compression/decompression. When you are preparing video for the web, you will most likely be transcoding the file. For example, you start with an H.264 file and convert it to MPEG4. This typically involves lossy compression. This is the process of changing one form of digital encoding to another. You can also add filters, subtitles, chapters, and other meta information to the file through encoding. All the compression happens during encoding. Video encoding is the process of formatting the file for output. A large amount of information is lost to reduce video file size. Lossy – a loss in quality in order to achieve a smaller file size.Even if there is a loss of information, there is no noticeable difference in quality to the viewer. Losseless – no loss in quality from the original file.Smaller files equal faster download/upload speeds. CompressionĬompression makes a file smaller. Below I will present some broad definitions of some important terms. But you don’t need a degree in physics to understand enough to edit video like a pro. For most people, the terms related to compression are confusing. This subject of compression can be complicated. This post shows you five ways to reduce video size for faster loading times. Because of this, compression is an important part of distributing your videos over the internet. Large files can be the cause of slow upload/download speeds. Internet connections are faster and more reliable than ever, but video files are still large compared to audio files or images. As technology evolves, so does our ability to share information.
