Why is my video so pixelated after putting through handbrake? I thought my settings were fine.
As mentioned those are different frames you are testing. Personally I use veryslow but most people here don't spend as much time encoding a single item as I do. Also don't use PNGs for checking use Video Compare . You can run two different MKVs at the same time and compare them frame by frame both in playback and pausing them.

Compare different models
use the Video-Compare tool. watch the demo here how it works

How do you guys visually compare clips?
https://github.com/pixop/video-compare This one is simple but really good

Is FFmpeg able to convert DVD iso to a set of mp4/mkv?
Well, I would use https://github.com/pixop/video-compare for that - it's the tool I normally use to compare videos (to find differences or to check image compression issues) but it can load the same video twice to watch it frame by frame. It even shows the type of frame I'm on so it's useful when I need to find a keyframe to do a video split with no recoding.

Downsides of fractional scaling
You can preview (export as preview) test of few presets, settings, etc. on TVAI and if you wish you could also use a compare tool to check the results to see for yourself if you notice any difference between them (that would save you tons of time). or just playback the 2s / 5s of the preview(s) you generate, right after the other to see if you spot any difference in quality.

Unusually good compression ratio - Sanity Check
If you need to compare images easily, consider slow.pics. Or ICAT, or Video Comparison Tool. And actually, even x264 and x265 don't have perfect CRF scales as well, they are offset by a constant iirc.

Can't trim a MKV file accurately without re-encoding?
You can easily check the type of each frame with the use of https://github.com/pixop/video-compare/ software - just use the same video twice (as video-compare needs two video inputs) and look for I, B, P letters near the current frame time.
- Hello friends! Which youtube download video type is higher quality? MKV 720p AV1? Or MP4 1080p? See pic below! -Thanks!

Extreme Video Compression
Netflix did VMAF for this: https://github.com/Netflix/vmaf
It checks a reference video against an encoded video and returns a score representing how close the encoded video appears to the original from a human perspective.

Linux GUI/Frontend for VMAF
Not sure this is the right sub but I'm going to encode my entire BluRay collection in AV1 / NVEC. I'd like to optimize settings with VMAF but would like an ubuntu/debian based GUI to work with.

Does anybody run libvmaf on your output as a validation check?
VMAF for anybody that doesn't know quantifies the quality difference between a source and modified video.

reduce video filesize
Netflix even has a method to measure perceivable quality difference. A little while ago I used this tool to calculate this.
-
How did my silly little After Effects filter reduce the file to 10% its size? The footage wasn't raw or 10-bit or anything, and I rendered it out at basically the same resolution (cropping aside). How did I do this????
Well you can use something like https://mediaarea.net/en/MediaInfo to look at the files and https://github.com/Netflix/vmaf to see if there is no loss.

4:2:0 10-bit HEVC vs 4:2:2 10-bit AVC codecs higher quality? (S5II, GH6)
You can try some tests https://github.com/Netflix/vmaf

Unusually good compression ratio - Sanity Check
You can try VMAF as well (which ffmpeg supports). It's normally recommended to make a lossless copy first as a baseline too
What are some alternatives?
When comparing video-compare and vmaf you can also consider the following projects:
vivictpp - Vivict++ is an easy to use tool for subjective comparison of the visual quality of different encodings of the same video source.
