# blend frames rather than using mci

# mci probably needs additional frames and processing to be useful

# Alternatively, mci
# Ensure you use filter:v so it only tries to process the video track (in case there's audio)
# Ensure you do "scale=NUM_SMALLER_THAN_4000:-1" first (before minterpolate) because 
# 	minterpolate can only process 4,000 something pixel (width? height?) frames,
# 	and larger values will cause a really stupid, meaningless error.
