This is a Shimano Clarus centerpin rod and and Okuma Aventa centerpin reel. I use the same Carolina rig you describe. Here the main line was 10 lbs hi-vis mono, to a swivel, then down to 9 lbs (5x I believe) trout tippet about a cubit or so. The hook I use one of my small thump rigs, an old-school, long-forgoten trout lure, then one of my Europen nightcrawlers for bait.
For weight I use a simple split shot just above swivel instead of a egg or bullet sinker that way I can change weights easily depending on the conditions.
The camera for this video was just a GoPro Hero 11, head mounted. I have the stabilization on, settings are cinematic @ 24 frames per second, 10-bit color depth, 4:2:0 subsampling. The use the flat color profile. I have a combo polarizer/ND filter as well to get the shutter speed down. All that gives me a image somewhat approaching my cinema camera. I color grade in Lightworks. In addition to the flat color profile use -20% saturation, -10% contrast in Lightworks. I also do my own S-curve in RBG, creating more contrast in the gammas at the expense of the highlights and shadows. I also raise the shadows 10 point to give a slight milkly color, almost like a bleached bypass. I have to do all that just to get things looking halfway like my cinema camera, the Zcam E2C. I also use the look-up-tables from Panasonic's Varicam for final color. Their LUTS are free. I use "Vintage" almost exclusively.
