-4. As you can see, with the half of the original resolution you processed it in about `1/3` of the original time (`36 seconds` against `12 seconds`), so the resolution matters on the processing time. Also matters on the size of the file. On the call without the options, the final size was `14.2 MB`, with half of the resolution, it was only `4.6 MB`.
