The layout decides how many videos run at once and how they’re arranged. You pick it during setup and you can change it mid-session without losing your queue.
Play a portrait video in a widescreen slot and you get the clip in the middle with two dead black columns either side. On a four-slot wall with a couple of portrait clips, that’s a lot of nothing. Adaptive Mosaic measures those columns and drops more portrait clips into them, so the same grid that showed you four videos shows you eight or nine.
When that slot later moves on to a landscape clip, the extra columns disappear and the slot takes the full width back. You don’t manage any of it.
Fillers come from discovery
Not from your queue. They’re pulled from portrait content that matches your session’s filters, always muted, and streamed at a lower quality (around 480p) so the extra tiles don’t tax your machine. Sound stays with your real slots and the Mixer.
Every gap gets some company
When there isn’t room to fill every portrait gap, the wall trims the fullest cell first and evens things out. Four gaps of two become three of one and one of two, so every portrait clip still gets a filler rather than stacking them all beside one.
They re-plan as things change
Fillers snap in and out when a slot flips between portrait and landscape, and they re-plan when you resize the window. A portrait clip following a portrait clip on the same-size wall leaves them where they are.
The Fillers button turns them off
It disables and re-enables the extra clips without changing your layout, so you can calm the wall down without rebuilding it.
Caught something good in a filler?
Each filler has a corner control to add that clip to your session, or skip it and let the next one through. It’s a great way to build a queue — sit back, let the wall suggest, keep the hits.
Easier seen than read
Switch layouts and watch it re-pack.
The layout picker is in the player. Changing it mid-session doesn’t lose your queue.
Because it’s a Pass layout. Free covers Single, Dual and Triple; everything else — Quad, Focus, Mosaic, Six, Nine and Adaptive — is part of Pass, which during the beta is switched on for beta testers. It isn’t a straight slot-count rule: Focus is only three slots but still sits with Pass. Locked layouts stay in the picker rather than disappearing, so you can see what’s there.
What’s the difference between Mosaic and Adaptive?
They’re two different layouts with confusingly similar names. Mosaic is a fixed five-slot arrangement: one big panel spanning two of the three top columns, one panel beside it, and three across the bottom. Adaptive is a four-slot 2×2 that grows extra tiles on its own by filling the gaps beside portrait clips. If you want the self-filling one, pick Adaptive.
Triple and Focus both say three slots. What’s the difference?
Arrangement, not count. Triple gives you three equal panels in a row, and it’s free. Focus gives one large panel with two stacked down the side, and it’s a Pass layout — same three clips, but one of them is the main event.
How many extra clips does Adaptive Mosaic actually add?
It depends on how wide the cell is. A portrait clip in a roughly 16:9 cell has room for two more beside it; a narrower cell fits one. The wall caps at nine tiles total, so when there isn’t room to fill every gap it trims the fullest cell first, evening things out so every portrait clip still gets some company.
Nothing is filling my gaps — is it broken?
Probably not. Fillers only appear beside portrait clips, and only if there’s portrait content matching your session’s filters. If your session is all landscape, or your filters are narrow, you get an ordinary pillarboxed grid instead.
Can I keep a filler I like?
Yes. Each filler has a corner control to add it to your session, or skip it and move on to the next one.
Is Adaptive Mosaic heavier on my machine?
A little. It runs more video than a plain four-slot grid, though the filler tiles are small and stream at a lower quality (around 480p) to keep the load down. The layout that works your machine hardest is Nine, which runs nine full-quality streams at once. Either way, if your laptop starts sounding like a hairdryer, turn Fillers off or drop to a smaller layout.
