ffmpeg syntax to create movie from sequentially numbered frames

https://stackoverflow.com/questions/47670918/create-video-from-images-sorted-in-numerical-order-using-ffmpeg

ffmpeg -framerate $FRAMERATE -i "image%05d.jpg" output.mp4

and if we want XVID,

https://trac.ffmpeg.org/wiki/Encode/MPEG-4

ffmpeg -framerate $FRAMERATE -i "image%05d.jpg" -c:v mpeg4 -vtag xvid output.avi

(not yet tested for compatibility with our Blu Ray player.)

What I've used for 4K frames, 

ffmpeg -r 30 -f image2 -i "paranal_timelapse_vst_%05d.jpg" -vcodec libx264 -crf 15  -pix_fmt yuv420p paranal_timelapse_vst-4k-frames.mp4

Edit: 

# for starting at arbitrary frame number

ffmpeg -r 30 -start_number 405 -f image2 -i "paranal_timelapse_vst_%05d.jpg" -vcodec libx264 -crf 15  -pix_fmt yuv420p partial.mp4
