The sentence "If you had watched till the end, you’d would’ve seen that the benefactor has gotten all of it already" contains a small grammatical error: "you’d would’ve" is incorrect because "you'd" (you would) and "would've" (would have) shouldn’t be used together in that way.
A corrected version could be: "If you had watched till the end, you would have seen that the benefactor has gotten all of it already."
