Convert sequence of GoPro Hero 5 Black JPEG images to MKV / MP4 video

MKV is an open standard, so I prefer that to MP4, it does also seem to play back 4k 60 fps less choppy.

ffmpeg -r 60 -pattern_type glob -i '*.JPG' -vf scale=3840:2160 -sws_flags lanczos -pix_fmt yuv420p -vcodec libx264 -crf 18 -preset slow timelapse_lanczos_crf18_slow.mkv

• -r 60 - output frame rate.
• -pattern_type glob -i '*.JPG' - all JPG files in the current directory.
• -vf scale=3840:2160 - 4k UHD. GoPro captures in 4000x3000, but I want to squeeze it into 4k.
• -sws_flags lanczos - I want to scale Gaussian or lanczos, I think it’s better than bicubic.
