Comparing compression in AV1, x264, and x265

I recently got it into my head to compare the various popular video codecs in an effort to better understand how av1 works and looks compared to x264 and x265. I also had ideas of using a intel video card to compress a home video security setup, and what levels of compression I would need to get good results.

The Setup
I used the 4k 6.3gb blender project, tears of steel as a source. I downscaled the video to 1080p using all three codecs, and then attempted to compare the results using various crf levels.

To compare results I used imgsli, FFMetrics, and my own picture viewer to try and see what the differences are.

The Results

Here is av1 rcf 36 vs crf 24.

I go into more detail with the hows and whys of my choices, in my journal-style blog post, as well as how i came to these conclusions, But in essence, if you want to lose practically no visual information, crf24 through 36 for av1, crf 21 for x265, and crf 18 for x264 will do the job.

If you are low on space, using my 'good enough' choices will get you practically the same visual results while using less space, depending on the codec.

Dynamic DNS domain registrar

Hey y'all, I've been using my.freenom as my domain registrar for the past six years without too many issues. I've kept it mainly because it has been cheap as balls. However, I am now looking for a registrar that supports dynamic dns and would love to hear your suggestions. The first results that pop up are google and godaddy which are not what I'm looking for. (I actually had issues with godaddy stealing domain names all the way back in 2010, but that's another story) A local community reference is worth a lot more to me than a top search result.

The plan is to set up my domain to point to my local IP for stuff like valheim servers so i don't have to share an IP every time we want to play. My friendlywrt router supports dynamic dns out of the box, so that's what I'm looking to use for my domain.

Also, it needs to support subdomains going to different places. Complete access to the dns records is enough, but I would love a more user friendly interface for adding things like a separate email host, a webhost address, plus a subdomain for the valheim server.

Local only scripts and style adjustments on a company website?

Hey y'all. I have a work pc that has chrome and edge installed on it, but can't have any extensions added due to security reasons. I primarily work with a web program that is purpose built for my job. I would to adjust the css of the website on a permanent basis in order to make my work easier. Is this possible using only the default browser settings / addons?

The f12 development tool has shown me that it's possible to make the adjustments i want on the fly, but I would like to make those changes permanent to my web browser.

As far as I know chrome used to support user scripts but has made it impossible to do with a modern version. I found less results for edge.

A good open source sms app?

Hey y'all. Like the title says, I'm looking for an android sms app. I used to use signal, but they removed support for it in October last year. I switched over to qksms which has been great, except it doesn't support video, only pictures for MMS. The default app that came with my phone doesnt support group chat titles, and sms messenger from f-droid says it supports video mms, but it keeps failing to send video (despite the size being 1.4Mb). Y'all got any other suggestions?
