I use the approach described in the link below, combined with a shell script to manipulate the desired set of files.

How to make scientific movies with ffmpeg - http://web.mit.edu/robyn/www/ffmpeghowto.html

Script (bash):

#!/bin/bash

root=~/your/path/goes/here/
mission=$1
year=$2

# Set working directory to the specified root [data] directory.
cd $root
# Remove any existing temporary image symbolic links.
# Generate temporary image symbolic links to requested static image files,
# then generate animation from the sequentially numbered temporary images.

rm /tmp/img???.png

x=1; for i in ./$mission/$year/???/${mission}_data_${year}*.png; do counter=$(printf %03d $x); ln "$i" /tmp/img"$counter".png; x=$(($x+1)); done

ffmpeg -f image2 -r 6 -i /tmp/img%03d.png -b 3200k -y ./${mission}_${year}_data.mp4

# Set working directory back to original location.
cd -
