I’m completely new to ffmpeg and have 2 questions:

1. How can I convert 16:9 movies to 2.35:1? My projector can’t scale down and 16:9 movies run outside my 2.35:1 canvas at the top and the bottom. I need to black out top and bottom so only 2.35:1 is visible.

2. My old Yamaha surround can’t decode true HD. Is is possible with ffmpeg to convert the sound to DTS 7.1?
