+Here is how to generate a mp4 movie from a number of .png images. Each image is shown 2 seconds (-framerate 1/2). The resulting movie has 25 fps (-r 25) and 4K resolution (-s 3840x2160). The filenames of the images are read from the filesystem (-pattern_type glob  -i '*.png').
 {{{#!ShellExample
+ffmpeg -framerate 1/2 -pattern_type glob  -i '*.png' -vcodec libx264 -crf 25 -s 3840x2160 -r 25 foo.mp4
+}}}
+
+
+Just some more examples:
+{{{#!ShellExample
+ffmpeg -r 2 -f image2 -s 1920x1080 -i B1-gBMO%03d.png -vcodec libx264 -crf 25  -pix_fmt yuv420p foo.mp4
+ffmpeg -f image2 -framerate 12 -i foo-%03d.jpeg -s 1920x1080 foo.avi
 ffmpeg -i input -c:libx264 -profile:baseline -preset:ultrafast -level 1.2
