[FFmpeg-user] Image sequence to h264 anything but grayscale is black

When compiling an image sequence of pngs to h264, if the image has any
color the resulting video is all black frames. If the images don't have
color (grayscale) the video plays perfect. Am I missing some dependency or
something? Any help is greatly appreciated!
Below are the two outputs of ffmpeg. It's the same mp3, and the same image
sequence for both of these except one batch is color and one is grayscale.
ffmpeg -i audio.mp3 -f image2 -r 24 -i %6d.png -vcodec libx264 -acodec
libfaac -ab "96k" -ac 2 -b:v "780K" -y output.mp4
Color Images Output (results in black image for the duration of the video,
audio plays)
