On Windows, I've used [Solveig Multimedia Video Splitter](https://www.solveigmm.com/en/products/video-splitter/) and it will cut the video on exactly the time range listed (example: `00:11:34.004` to `00:34:45.005`)

I've tried a freeware app [LosslessCut](https://electronjs.org/apps/losslesscut) (which uses FFmpeg) and it only trims cuts on the B-frames I think.

Any suggestions? Thanks.
