I created a cool scene that I want to create as a poster, the problem being that I need a high resolution image. The highest resolution video that can be rendered is 4096 by 2304 pixels, which is okay for medium size images but still annoying to try to render as an image. (The best way I've found is to use windows "edit photo" option on the mp4 video to capture an image)
Please make it possible to capture higher quality images as an export option. A few other suggestions have hit on this but weren't very clear on this option.
