Took me quite a while to remember where I remembered something similar happened before:
Kind of like how, in G4, the Mane Six had their lip sync for the lines, “It says that they like jousting”, “make sweets of crystal berries”, and “they had a petting zoo with tiny ewes” removed in the final version of The Ballad of the Crystal Empire.

@Shimmering Spectacle
Unfortunately nope.

@Shimmering Spectacle
Imagine of Jazz had no eyes…

That would be… interesting

(Mostly satire. Don’t take too seriously)

@Jonny Manz
oy, I really hope that’s what they’re planning on, it’s just annoying that they like removed her eyes on purpose.

@Shimmering Spectacle
I would laugh if there was a shot, perhaps in the cold opening of an episode, where the Mane 5 are looking at Jazz for whatever reason, and suddenly, her ears unfold from her mane. She then is like “what?” To the Mane 5, and then the opening theme

@Jonny Manz
unless they say that she has her ears hidden under mane, I’m not buying this.

@Shimmering Spectacle
But on the bright side, Misty’s horn and Sugar Moonlight’s phone were fixed compared to the trailer, so it was a net gain, I suppose, haha

are you kidding me?!

Wow. The last names didn’t even occur to me. I’ve already heard some people in the disability community working with the headcanon that earless is her normal state. At this point, it wouldn’t hurt in the least if they just rolled with it in the same way the G4 team did with Derpy.

@Jonny Manz
Yeah, I agree. She shares the same last name as Derpy so it kinda fits

@The Crystal Artist
I think it’s mostly down to the constraints of 3D animation as compared with 2D - with 2D, you can cheat at the angles so the break in the hair for the ears is just implied, or draw it as a simple line through the hair, and our brains will fill in the necessary information. You can’t do that with 3D - as demonstrated above, the ears kind of awkwardly clip through the hair unless a specific hair pattern is modeled into it to allow them through.

Part of me hopes they fix that for chapter 4 (since chapter 3 is likely to be the Winter Wishday special), but part of me is kind of happy having Jazz as this generation’s Derpy.

They chopped it off!

She’s a forgetful changling. Keeps leaving off the ears.

At this point, they should just run with it. Make her an undercover alien pony. Sometimes she forgets to put her ears on, but sometimes she remembers (like in TYT).

@Derpyfan
Studio to cheap to redesign her hair lol, but true

@eagc7
It would really just make more sense to change her hair in that situation.

@Derpyfan
As Background Pony #CE0D said its possible her mane phases right thru her ears and it doesnt look good, so they opted to have her earless

“Sir, we accidentally put ears on Jazz in the trailer.”
“Atrocious! Fix this mistake before the full chapter releases!”

I hope in Chapter 3, that will have an episode about her.

It’s possible that her ears clip through her hair, making it difficult to properly render them without looking even weirder than simply removing the ears and calling it good enough.

Jazz’s mane is so long, her ears just fully covered from it.

@northern haste
Can’t imagine that being a popular decision.

Yeah that has to be how they just want her to look

An episode is made up of several hundred small clips of video. That’s how dozens of animators can work at the same time. Once the release is made, all pieces are merged together to create the final video. Probably they didn’t use the last version of this scene by accident. Poor Jazz 😂

@BigBuggyBastage
Wouldn’t they have pony models where all the details of the pony are present? Sort of like how I’ve seen SFM pony models being used by the fandom.

Speaking of the checkboxes and the program, I did notice that Thunder didn’t have his armor neck piece on in one frame while in Mane Melody.

I’m not an animator nor would I be good at it, but I’ve always wondered this too.

I’m wondering whether there’s a pair of checkboxes in whatever program the artists are using, and they occasionally forget to set them properly. Something like this:
