ffmpeg: Save a video as GIF, scaling the height to 1000px and setting framerate to 15.

This command is using the ffmpeg tool to convert a video file (specified by the variable video-mp4) to a GIF file (specified by the variable output-gif). Here's a breakdown of the different parts of the command:

ffmpeg: This is the command-line tool for converting and manipulating multimedia files.
-i ${video-mp4}: This specifies the input file (video-mp4) that you want to convert.
-vf 'scale=-1:${1000}': This applies a video filter (-vf) to the input file. The filter used here is to scale (resize) the video. The option scale=-1:${1000} means that the video's width will be automatically adjusted while maintaining the aspect ratio, and the height will be set to 1000 pixels. The ${1000} represents a variable with a value of 1000.
-r ${15}: This sets the frame rate (-r) of the output GIF to 15 frames per second. It uses the value of the variable 15.
${output-gif}: This specifies the output file name for the GIF file. The actual file name is stored in the variable output-gif.

Overall, this command takes a video file, resizes it to a height of 1000 pixels while adjusting the width proportionally, sets the frame rate to 15, and saves the resulting GIF file with the specified output file name.
