How to upload a video to Instagram via computer?

Question

Social media

Doesn't load via BlueStacks. Found Gramblr but he needs to give a password, it's doubtful somehow.
Naturally, the option of downloading to the phone, and then to Instagram, disappears.

Answer 1

Upload the file to your phone, and from your phone upload it to the social network

Answer 2

With the new API, you can only upload materials to your account from official applications.
