If you use a card having a slow writing speed, a five-level

If the indicator becomes full, movie shooting will stop

If the card has a fast writing speed, the indicator will either not
appear or the level (if displayed) will hardly go upward. First,
shoot a few test movies to see if the card can write fast enough.
