If no padding is needed use something similar to pic%d.png or %d.png. Where the %04d means that zeros will be padded until the length of the string is 4 i.e 0001… 0020… 0030… 2000 and so on. etc) use the following command: ffmpeg -r 60 -f image2 -s 1920x1080 -i pic%04d.png -vcodec libx264 -crf 25 -pix_fmt yuv420p test.mp4 To take a list of images that are padded with zeros ( pic0001.png, pic0002.png…. I have noticed that different versions of ffmpeg will produce different output file sizes, so your mileage may vary. When using ffmpeg to compress a video, I recommend using the libx264 codec, from experience it has given me excellent quality for small video sizes.
