Both the simple form and the -ing form are grammatically correct, so you can't make a grammar mistake. But a speaker might choose one over the other. Read the situation, then decide which form seems better to you in the sentence that contains a verb of perception. Remember that the -ing form gives the idea that an activity is in progress when it is perceived.
