In this FFmpeg tutorial, we learn to change the resolution of a video (or resize/scale a video) using FFmpeg’s commandline tool.Ĭhanging a video’s resolution (also known as resizing or scaling) is a very common operation in video editing, processing, and compression.

The Constant Rate factor (CRF) is the default quality setting for x264 and x265 encoding. Using the CRF of values between 0 and 51 should provide the best compatibility for x265 codecs. The x265 codec is a free library for encoding video into H.254/MPEG-H HEVC compression format. In this tutorial, we will use the x265 codec. First, we need to select a small container, an excellent codec to encode the video, a low bitrate, and a low fps. To make the best decision in video compression, we implement a simple equation. For example, an AVI video file might still be larger than the small file of MP4 type despite being a small size. There is no universal way to reduce a video file size because various file types are not created equal. However, to compress files efficiently, we need to use codecs, bitrate, container, and fps. The command above will convert the file from the specified format to the output format.
