I was able to get a version to work by removing some potential file conflicts and then compile the images via ffmpeg: ffmpeg -loglevel warning -f image2 -framerate 30 -y -i "GofarAnimation6_G3Glide_backup2/GofarAnimation6_G3Glide_%05d.png" -vcodec libx264 -pix_fmt yuv420p GofarAnimation6_G3Glide_30fps.mp4
Here is my pre.sh (I am well aware that there is a bunch of bash jargon and variables here and that you do not have the data etc. to run these files):
gmt begin
gmt set FONT_ANNOT_PRIMARY 8,Helvetica,black FONT_ANNOT_SECONDARY 8,Helvetica,black FONT_LABEL 8,Helvetica,black FONT_TITLE 10,Helvetica,black
gmt set COLOR_BACKGROUND black COLOR_FOREGROUND white COLOR_NAN white GMT_CUSTOM_LIBS /usr/local/lib/mbsystem.so
gmt set FORMAT_GEO_MAP ddd.xx MAP_FRAME_WIDTH 3p MAP_ANNOT_OFFSET_PRIMARY 5p
gmt makecpt -Clapaz -T-4000/-2500/1 -Z -D -H > main.cpt
# Set up flight path: -G is the spacing of each frame in meters.

gmt project -C-106.25/-4.5125 -E-105.50/-4.6675 -G10e -Q > flight_path.txt

And my main.sh:
gmt begin

It is still unable to produce some frames and some other frames show a wonky grid:
frame 3740 vs 3741, where 3740 has a grid on the left that is squished for a single frame.
