[Hi Score Girl II](https://myanimelist.net/anime/39570/High_Score_Girl_II)
Obligatory 60fps explanation below.
So I thought I'd take a little bit of time to explain the 60fps aspect of this show.
When you open the mediainfo for the Season 2 BDs, this is what you see:
We all know what the "frame rate" part means: it means that there are 29.97 frames that display on screen every second. But what about that text at the bottom? The "interleaved fields" and "top field first"? That text means that each frame is made up of two distinct parts. The horizontal lines of the frame numbered 1, 3, 5, 7 ... 1079 make up the "top field" of the frame, and the horizontal lines numbered 2, 4, 6, 8, ... 1080 make up the "bottom field." In some setups, the fields would display one after the other, top field first. Here's a relevant diagram:
So because each frame has two distinct parts called fields, and there are 29.97 frames per second, there are 59.94 fields per second.
What would it look like if we looked at a video that had all 60 fields played in a sequence? Well, for one thing, it would probably be in 540p, since we just talked about how each field has half the horizontal lines of the original frame. And it would have a strict playing order, since Mediainfo told us which field to play first: the top field of each frame comes before the bottom field.
So [here is a video](https://www.youtube.com/watch?v=NYO-6zM97tw&feature=youtu.be) of exactly one second of footage from **season 1** (specifically, episode 1, 00:06.5-00:07.5).
There are 60 fields in this one second of footage, and you can hopefully see from the video that the underlying footage is meant to have 60 pieces of information per second. For example, E. Honda's shakes happen at 60hz, and you can see a falling droplet of water at some point falling at 60hz.
The goal of the encoder, then, is to take what is essentially 540p footage and expand it into 1080p footage, using information from fields/frames before and after, motion prediction, etc. That's the only interpolation going on here: an upscale from 1920x540 to 1920x1080. Not an "upscale" of 30fps to 60fps. (Though, note that a resolution upscale is unnecessary during the 24fps parts (i.e. the majority of the video), since you can always simply paste two fields together to get the true original frame.)
## Another season, another tier list
**Good-tier** (correctly deinterlaced 60/24fps VFR):
**Okay-tier** (decombed and either (1) constant 60fps, or (2) correctly implemented 24/30fps VFR):
jsum (?) (24/30fps VFR) (not available on nyaa)
SonicBoom (24/30fps VFR, very rare combing)
Netflix rips (e.g. DragsterPS) (constant 30fps, so most scenes with pans look jittery)
Ohys-Raws (constant 30fps. Also, what's with the absolutely obnoxious amount of static grain?)
EMBER (no fieldmatching whatsoever, so there is combing all over the place)
