Exporting high FPS movie files

I am piping in a 260FPS feed into a moviefileout TOP, recording that and wanting to play that back at 24FPS, but it seems moviefileout TOP is clamped to the timeline at 60FPS. Is there a way to fix this without having to change the timeline FPS?

You can turn off the realtime flag at the top of the interface and all frames will be recorded.
