Heya. Lately, I've been using Adaptive Bass Monster Open in parallel mode with the second multiband completely nullified (1:1, no gain boosts, etc) with the mix slider around 50%.
This allows me to use the Parallel Multiband Compression (mix) slider to reduce the intensity of the ABM-Open preset to achieve however much compression I want without going in and tweaking a bunch of sliders at once. Dialogue in movies is present, and the action scenes aren't overwhelming. Then I can tweak the slider in the other direction for more dynamic music, instead of loading a different preset.
However, since it's Adaptive, it'll use a little more CPU than the other compressor modes. One can tweak the CPU cores used in ST, in case you need to set it to use a core your video player isn't using. Also, shouldn't the video be GPU-bound, leaving plenty of CPU room for Stereo Tool to do all it needs?
I'll look into Zoom player at some point. I use PotPlayer
https://potplayer.tv/ when I want to use the ST DSP plugin on a video, such as when streaming on Discord. And I use the standalone ST app with MPC-BE when I want to watch something in HDR.
