Can you please try disabling Graphics Acceleration in the browser and tell me if this makes any difference? Settings --> System --> Graphics Acceleration
Also worth noting we do have an open issue for this with respect to Youtube:

### Description
A good handful of users have been reporting sites like Youtube … using a disproportionate amount of memory in Brave after updating to v1.65.114. Some users claim a single tab using upwards of 1GB of memory. I have asked users to submit images of browser task manager/memory tooltip.
OP has tested the following:
- New profile: no change in behavior
- `Graphics acceleration` disabled: no change in behavior
- Tested Beta build: no change in behavior
- Fresh profile: no change in behavior
- Private browsing windows: no change in behavior
- Clearing browsing data: no change in behavior
### Steps to reproduce
1. Visit youtube/other video streaming sites on macOS
### Actual result
