I know, but I figured it would be obvious from the example that it does not
"simply" work that way since the transparent PNG is automatically encoded
with to an MPEG-4 or H.264 bitstream unless other options are supplied.

Both png and qtrle can be put into an isom container and read by

 Would you have an example command of how to achieve that?
