Hello,
I've got an anamorphic adapter from SLR Magic and I'm shooting in 4K at GH4.
I'm not sure when/which ratio I should choose, it is quite a new thing for me.
GH4 has 4:3 anamorphic mode, the result is wide and fits fro Vimeo and YouTube but for Instagram is it too wide.
So my question is: Do I have to shoot 16:9 IF the footage will be uploaded at instagram or can I still shoot 4:3 anamorphic and edit it later to 16:9 resolution?
