Admittedly, shifting aspect ratios within a single film is somewhat of a rarity and may not be something you need to worry about, but it seems to be increasingly common in some genres and with certain directors, so it's always good to double-check your source material to make sure you're not losing anything when autocropping.

The input video’s width and height can be denoted by inw / iw and inh / ih respectively. Other popular movies have changing aspect ratios as well, like Dark Knight, GotG, Capt. Crop a Video in FFmpeg with Variables We can implement the video cropping command using variables to denote the video parameters. If I used something like Handbrake and turn on the auto crop settings for something like TRON Legacy, it almost always thinks that the initial aspect ratio is correct for the entire film, which incorrectly crops the lightcycle scene's IMAX footage instead of preserving the entire frame.
