Downconvert footage to IO device.
For users who own an HD monitor connected to an IO device like a decklink card to get true 10 bit signal, anything above HD timelines give no output. Premiere & After Effects need a feature to seperately have a resolution for downconverting footage to the reference monitor. Not having this feature makes owning thousands of dollars in equipment useless. Your stepbrother Davinci Resolve can do this :)
