OK. the game must check if at least can play 1 sec. video (44 frames can make that 1 sec.).
now... let play with RAD - just for fun
if you set to compress video as grayscale & the scaling type to low quality and compress the audio to 99% and 8 bit mono you'll get a 10.4k file.
if you resize the file to 102x57 (10x less than actual size) you get a 8.98k file.
its almost 6x shorter than your file. can reduce it to 1 pixel size and the game be able to play it? - am going to try latter. lol.
