![]() To understand how compression works, there are a few terms you need to understand. Unless your goal is achieving the highest resolution possible, having smaller video files is best for everyone. Video compression refers to the process of encoding a video in such a way that it uses less space than the original file and is easier to share across different devices and over the internet.Ĭompression reduces file size by eliminating redundant and non-functional data from the original video. Depending on the frame rate, raw 1080p HD footage can consume more than 10 gigabytes of storage space per minute of video. Keep reading to learn how to compress a video and the different video compression methods that you can use. Compressing your videos reduces bandwidth usage and file size, drastically improving the video creation and editing process. This is a problem that videographers, editors, and content creators face every day.Ĭompression is the most effective way to get around the frustrating limitations on email and hosting platforms. Large video files can be a challenge when it comes to uploading and hosting. But like most videos we record these days, your footage turns out to be too large. Now you want to share it with your partners or perhaps get some input from the client. To choose this option, choose "Re-size video" from "Advanced Settings" above.So, you have made the perfect video. For example, if you have a 4K (4320p) video but your target device is 1080p, you can downsize the video to fit 1080p and save file size. 4: Make Video Size Smaller (Re-Size)Ĭhoosing a smaller video resolution (dimensions) can also save file size. For more info: read video bitrate control. To choose this option, select "By Max Bitrate" from the "Video Compress" dropdown. ![]() Select this method if you are using the video in a streaming application where you want to control the streaming bandwidth rate. The quality is set by CRF (constant rate factor). ![]() This method allows you to set the max bitrate for given video quality. This is the default video compression method used. Increase the target size if you need better quality. To overcome this, start with a decent size (as a percentage of original), then test for video quality. The downside is you don’t know how the target size will affect video quality. The pros of this method are, you can achieve a certain target size. For example, if you set it to 60% for a 1Gb file, we will attempt to make your compressed file size 600Mb or less. This method allows you to set a target file size for your video as a percentage of the original size. As a Percentage of the Original Size (Default) If you prefer a lower file size over encoding time, choose a slower preset. Choosing a slower preset allows better optimization (lower bitrate/file size) for a given video quality level. Preset: Presets refers to the video compression speed. Higher values mean more compression (reduced file size), lower values mean better quality (but bigger file size). For the H264 encoder, possible CRF values range from 0 to 51. To do that, it uses different compression levels on different frames. By Video QualityĬRF (Constant Rate Factor): CRF method attempts to keep a constant perceived video quality. ![]() We provide 4 settings related to both methods. You can either optimize the bitrate or resize the video to a smaller size. There are two main methods to compress a video.
