Seeking Advice to Reduce Artifacting Near Edges

I've starting using AV1 recently since learning about the SVT-AV1-HDR fork (I was very unimpressed with mainline SVT). I've generally been getting better results than HEVC with this fork. I'm currently trying to encode a high quality 4K HDR video to 1080p to save space. For grainy videos, I generally aim for 10-15Mbps with HEVC. I haven't done that many encodes with AV1 yet, but I've seen similar or better quality at 8-12Mbps with the few that I've done. On this one that I'm working on right now, It looks really good at 10Mbps except that I'm seeing artifacts on some of the edges. Particularly edges that move slowly across a grainy background. In the attached picture, it's kinda hard to see the artifacts, but it's more obvious when the video is going because there's no grain moving in that area and it follows the character as they move like it's attached. Normally I would just increase the bitrate until I can't see it anymore, but in this case even doubling the bitrate to 20Mbps doesn't fix it which is a pretty high bitrate for 1080p AV1/HEVC.

I'm using SVT-AV1-HDR 10bit, tune:grain, preset 4-2, ABR. I'm not interested in using grain synthesis or anything that's going to remove the original grain. If anyone knows any relevant settings that can help with this, please let me know.

I Edited Out Gandalf's Staff Breaking

I didn't read the books but I'm familiar with the lore and it doesn't make any sense to me that the witch king is able to break his staff so easily. This is the version I'll watch now.

Edit: sorry for the slight audio sync issue, it's from screen recording it. I didn't notice until someone mentioned it.

Is this real or fake?

Got it at Goodwill for $7. The visible wires looked like a red-flag to me but it felt right in the hand. I tried to do a warranty check when I got home just see if anything would come up; when I put the serial number in, it says "8 characters remaining"

Oh and idk if this means anything, I put a socket on large enough to get a good grip to feel how much torque it makes and it feels noticeably weaker than my gen3 m18 impact driver.

Anyone else been seeing this Terminal app?

I'm assuming it's a system app because it has the "Disable" option instead of "Uninstall."

​

Starting showing up after I was trying to patch different versions of Instagram to remove reels and the "for you" nonsense. That's when I noticed it at least. I think it's unlikely that it showed up long before I noticed it because my app drawer is pretty clean.

​

Revanced Manager and AntiSplit-M were the apps I actually installed. I downloaded a few different versions of Instagram from APKMirror but never installed any because I couldn't get any to patch successfully.

​

I think they're probably unrelated but that's the only thing I did that was out of the ordinary around the time I first noticed it.

Edit: It looks like I fixed it. I had added it to deep-sleeping apps. Since removing it from deep-sleeping apps, it's not showing up in my app drawer anymore.

This is how Valheim does it. Valheim has public and private worlds/lobbies, it just does version checks. Even if older versions only worked in single player, I'd still appreciate the option to play older versions. Especially now.
