removing letter boxing while preserving aspect

I have 3:2 content that is saved in a 4:3 frame with black bands at the top and bottom. I want to remove the banding such that the output is a 3:2 resolution clip WITHOUT DISTORTING THE ORIGINAL CONTENT. I've tried playing with the crop filter but the black bands remain, and the camera automation can remove the banding by zooming in, but then the left and right image sides get cropped out of the output. Is there a tutorial for this exact scenario?

My laptop was making noises under load, and sadly trayfreq was unable to set cpu frequency for some reason. I poked around /sys and found intel_pstate driver can be configured this way: echo 25 > /sys/devices/system/cpu/intel_pstate/max_perf_pct this sets max frequency to 800 mhz instead of 2.5/3.0 ghz as usual. note that 25 is percentage, and on different core iXXX processors results can be different. inxi CPU: dual core Intel Core i5-2450M (-MT MCP-) speed/min/max: 798/800/3100 MHz Kernel: 5.6.14-x64 x86_64 Up: 27d 14m Mem: 2453.5/5887.8 MiB (41.7%) Storage: 610.63 GiB (76.4% used) Procs: 227 Shell: Bash inxi: 3.3.12 I hope this might help Phyllis with her overheating intel laptop .....
