I'm new to Handbreak but I'm using it because I was told it would allow me to convert mp4 videos to an appropriate format for e621 with no degradation in quality. It just looks like I've stepped into the cockpit of a Boeing aircraft with all these buttons. I've watched tutorials but none of them are telling me "These are the buttons you want to say these things, for it to work best on e621." If anyone can help me with just figuring out how to correctly convert these videos using this soft ware, it would be much appreciated, and I'd write it down so I do the exact same thing everytime.
