Creating Portrait and Landscape Video Set Images with FFmpeg: A Simple Guide
In this article, we will discuss how to create a video set with both portrait and landscape images using FFmpeg. This is a useful technique for creating videos with a variety of aspect ratios. For the purpose of this guide, we will cover two combinations of dimension: 640x360 and 360x640.
What is FFmpeg?
FFmpeg is a free and open-source software project consisting of a vast software suite of libraries and programs for handling video, audio, and other multimedia files and streams. It is widely used for format transcoding, stream streaming, and various other tasks related to multimedia.
Creating a Video Set with Portrait Images
To create a video set with portrait images, you can use the following command:
ffmpeg -framerate 24 -i input_%03d.png -c:v libx264 -crf 18 -vf "format=yuv420p,scale=-2:360" output.mp4This command uses the -framerate option to set the frame rate of the output video to 24 frames per second. The -i option specifies the input images, which should be in the format input_001.png, input_002.png, etc. The -c:v option sets the video codec to H.264, and the -crf option sets the constant rate factor to 18 (a lower value means higher quality but larger file size). The -vf option applies video filters, in this case format conversion to yuv420p and scaling to a height of 360 pixels while keeping the aspect ratio the same.
Creating a Video Set with Landscape Images
To create a video set with landscape images, you can use the following command:
ffmpeg -framerate 24 -i input_%03d.png -c:v libx264 -crf 18 -vf "format=yuv420p,scale=640:-2" output.mp4This command is similar to the previous one, but instead of scaling to a height of 360 pixels, it scales to a width of 640 pixels while keeping the aspect ratio the same. This results in a landscape video.
FFmpeg is a powerful tool for creating videos with a variety of aspect ratios. By using the -vf option to apply video filters, you can easily create videos with both portrait and landscape images. In this guide, we covered two combinations of dimension: 640x360 and 360x640.
