Need Help Figuring Out FFmpeg’s Default Options

[DeadSkullzJr]

Hello everyone, as the title implies, I am trying to determine every little thing FFmpeg uses when encoding / processing a video stream. About a week ago I found out FFmpeg automatically runs options of sorts by default on the videos I created straight from DVD iso images. It seems to automate pulldown removal and such, and due to the automation, it doesn't always work the way I would like it to. While I already have a method that gets the job done, I am remaining open to explore my other options. My idea is to poke around and see what it performs automatically, and see if maybe I can override and or reproduce the same default option usage that it performs in a more controlled fashion. The problem is I can't seem to figure out what options are being automated as I am not able to pinpoint anything other than the options I specified using the -report option. Either that, or I am not understanding aspects of what it's doing to make the translation in my mind on what possible options it is using.

If you increase the loglevel to debug ffmpeg should output exactly what it does,...
