PNG files: convert -density 600 slides.pdf -strip -resize PNG8:slide-%02d.png My first step was to use the convert tool to convert the slides into separate If you want to follow along, create a directory and download the PDF slides: mkdir fun-with-im

I wanted to document how I did this for my own memory, and in case someone else GUI-based image editor was converting a series of PDF slides into an animation One recent task for which it spared me from having to resort to using a Successfully to script solutions for many of my image-editing needs. I should preface this post by declaring that I am not an expert on the use of However, we don’t need to specify this option at all.Īlternatively, we can shorten the command: $ ffmpeg -pattern_type glob -i '*.png' -r 60/30 out.gif 3.2.Provide several command-line tools capable of meeting all your imageĮditing/conversion needs, there are also APIs for over a dozen languages, This can save us some space if we need it. Since 60/30 evaluates to 2, FFmpeg will pick an image every two images. Therefore, using -framerate and -r, FFmpeg will interpret this as 60/30. The problem here is that image files don’t have framerates. However, we already have it specified in the -framerate option. The -r option that we used is an interesting one. FFmpeg figures out the target format from the extension. We specified our output filename as anim. -r signifies how to pick images based on the framerate we provided.-i option specifies our input PNG files as a glob pattern.-framerate option expects the number of frames per second for the output file.-pattern_type specifies that type of pattern we can use to conveniently select our images.

gif extension: $ ffmpeg -framerate 60 -pattern_type glob -i '*.png' -r 30 anim.gif Like convert, we feed our input PNG files to FFmpeg, apply some options, and specify the output filename that ends with a.
