at 1:25-1:30 it appears to use an editable image to create a flashbang effect,
what i'm wondering is how they read the pixels of the screen to send to the editable image? reading the pixels of the screen seems very useful, so i am curious to know how it can be done

now i'm insanely curious and im only typing here so i can follow the post and see if someone knows

ive been curious since i saw it first 3 months ago

pretty sure it can be done by cloning the area the player was at, then insert it to a viewportframe, not sure how they freeze the animations at the specific frame

[west yarrow]

I think they actually get the screen, you can see the ui and it has post processing not supported by the basic dot product lighting of a viewport frame

https://devforum.roblox.com/t/realistic-flash-effects-easy-to-use/3321823 found this on the dev forum, im gonna try it later

maybe its that

local capture=game:GetService("CaptureService")

while task.wait(1) do
capture:CaptureScreenshot(function(ImageId)
script.Parent.ImageContent=Content.fromUri(ImageId)
end)
end

The reason why you don't see this in games is: A: its an uncommunly used service that roblox barely gives publicity on
and B: Roblox refuses to let you convert this imagecontent into an editableimage, thus continuing their efforts to make editableimage as useless as possible,

this would be the second biggest use case for editable image, being able to make cool shaders with the screenshot data, although due to a malicious game potentially being able to see your robux balance, nobody gets access to it??

the first biggest use case for editable image is modifying decals, such as importing decals from the catalog and reading their pixels for stuff like dynamic eye position reading on faces for eye effects, and potentially image modification software, although roblox refuses access to:
roblox owned assets (even the heavily restricted insertservice lets you do that!)
assets with the permissions tab given access to the game owner
assets on the public creator marketplace
if its to prevent bad actors from showing malicious content in games, they can still just make malicous images from external buffers that would be equally hard to moderate

the only use case for this is putting a screenshot of the game on a decal to mess with the player, tinting the screenshot color potentially for a horror game by tinting it red(even though you already could do that with colorcorrectioneffect), simulating a lag effect, or as the specified video showcases, a flashbang effect
