I am trying hard to make one that looks as hypnotic, i have only manage to produce 110MB monsters or they are 0:05 long , or the size of a stamp, or look do not look as fluid can you help with the settings you used ?
I have played with DPI, size , number of image and delay yet , am i missing a thing ?
Edit, here my best attempt that is 25MB, I can't get as nice colors as yours when i use only 8 of them, and it really seems to make the difference in size file there are 460 of them for 28 seconds, maybe because of the train speed difference on my congested network it doesn't look good when i try to halve the number of image even further.
I had to use a command to get rid of all radars of the map and empty some chest , launch rockets, fabricate modules, an tried to empty some buffer to artificially increase the traffic, to make it look like that, sadly not all trains are moving are some areas are not designed to be used a lot and i forget about them.
