Timelapse Export Resolution limited to 1920 HD even on 4K setting project size

Maybe this is a wish list setting, but when I am on a 4K canvas size, the timelapse only exports 1920 in width. Is there any way to up that or control the timelapse exported movie settings. Also is there a way to get the frame by frame, image sequence raw files of your drawing. I know this would be exhaustive to the app's ram but just wondering all these things...
