Can't render image strip as animation without camera in scene

I want to render an image strip in the Video Sequencer as an animation but when I click on Render Animation it says there is no camera in the scene. If I put a camera in the scene it renders what the camera sees (nothing) instead of the image strip.

Can I check what version of Blender you’re using? and have you maybe unticked the tickbox in the render settings > Post Processing > Sequencer ?

I’m using version 2.8, I just found that the problem was that I needed to select Sequence Render Animation from the Video Sequencer’s View menu instead of the main Render menu.
