"Did you remember to film everything?"

Translation: Vi siete ricordati di filmare tutto?

[SarahViaggi]

why is 'sei ricordato di filmare tutto' wrong?

[SchubertNo21]

It isn't wrong, although they may have wanted you to use 'Ti' as the Direct object pronoun.

[SamPelts]

Lol, instead of "ti SEI ricordato..." Duolingo's correction got confused and told me "ti 6 ricordato..."

[vivifie]

Is there any rule about when to use ricordarsi and when to use ricordare? It seems to be random. Why is ricordare wrong here? Is there a sense of the sentence when one or the other is appropriate?

[mozart8]

Of the two acceptable answers why is the singular you with "hai" and the plural your with "siete"?

[lunaexoriens]

I suppose that there are two different verbs: ricordare (which takes avere) and ricordarsi (which uses essere).

[Terence544359]

hai ricordato di filmare tutto is also marked correct

[Sybille.Holz]

@ Terence544359,
In my case, it was marked wrong. I wrote like you.

[J.Franchomme]

Please, I need someone to explain me why I am wrong!

-"Ti ricordavi di filmare tutto?"

[dnovinc]

Imperfetto is used to describe actions or conditions that lasted an indefinite time in the past. In my opinion the English sentence is referring to non repeating action in the past therefore we should use "passato prossimo"

[Germanlehrerlsu]

Also, and I may be wrong, but I believe or feel that most conversational exchanges like this - questions or statement - use the present perfect rather than the imperfect.

Again, hints that would help those of us "non grammer experts" are missing...
