When I first encoded a video, a small window opened that displayed the video frame by frame at the point it was currently being encoded. I accidentally closed this window, being an idiot, and I can't figure out how to get it back. It's important that I see the video being encoded so I don't waste a bunch of time to realise it didn't deinterlace correctly or something.
Thanks.

****, figured it out. If you also want to know, it's under the 'Picture' tab and is a checkbox simply labelled 'show encoding frame'. Haha good thing as well since I realise my Deinterlacing wasn't working.
