"Εγώ ανέβασα χθες ένα βίντεο."

[BillDe]

Yes English does have flexibility but nonetheless it does put adverbs of time at the end of a sentence, after both the direct and indirect objects. If you want to emphasis it you can put it at the beginning of the sentence. But it is not put between a verb and its object.

Word order for adverbs of time is after both indirect and direct object. English is not that flexible.
