ImageLabel keeps flickering after updating image id

Hi! I am doing a video by image frame by frame method, but after I updated the image id then the screen starts flickering. Is there any solution to this? Or do I need to preload the images?

I am currently using this method:
https://devforum.roblox.com/t/how-to-make-gifs-and-videos-on-roblox-full-tutorial/1667260

Here is my code:

local localplayer = game:GetService("Players").LocalPlayer
local rs = game:GetService("ReplicatedStorage")
local contentprovider = game:GetService("ContentProvider")

local camerashake = require(game.ReplicatedStorage.CameraShaker)
local Video = localplayer.PlayerGui:WaitForChild("Video")

local HollowPurpleIDTable = { -- 63 image frames goes here
	[1] = "rbxassetid://blabla",
}

game.ReplicatedStorage.RE.ClientFX.OnClientEvent:Connect(function(type, theone)
	local currentFrame = 0
	
	if type == "HollowPurpleVideo" then
		Video.Enabled = true
		Video.ImageHere.ImageTransparency = 0
		
		repeat task.wait(0.05) 
			currentFrame += 1
			local imageId = HollowPurpleIDTable[currentFrame]
			Video.ImageHere.Image = imageId
			print(currentFrame)
		until currentFrame >= 63
		
		game:GetService("TweenService"):Create(Video.ImageHere, TweenInfo.new(1.5), {ImageTransparency = 1}):Play()
		
		print('ended')
end
VHS Effect flickering off

you should preload the images. the reason it ‘flickers’ because the image needs to load in order to display in ImageLabel

#3

How do I preload it? I tried ContentProvider:PreloadAsync but it’s still flickering.

#4

What is your PreloadAsync code?

#5 
local preloadIDTable = {} -- asset ids here

local instanceTable = {}

for _, id in ipairs(preloadIDTable) do
	local instance = Instance.new("ImageLabel")
	instance.Image = "rbxassetid://"..id
	table.insert(instanceTable, instance)     
end

contentprovider:PreloadAsync(instanceTable)

I copied this from a post, I forgot which one though. And also editted this thing a bit.

#6

Can you try this and see what it prints?

local preloadIDTable = {}

local instanceTable = {}

for _, id in ipairs(preloadIDTable) do
    local instance = Instance.new("ImageLabel")
    instance.Image = "rbxassetid://"..id
    table.insert(instanceTable, instance)
end

local contentprovider = game:GetService("ContentProvider")
local success = contentprovider:PreloadAsync(instanceTable)

if success then
    print("They're all loaded")
else
    warn("Image preload failed.")
end
#7

It says “Image preload failed.”

#8

Update the last bit to this:

local contentprovider = game:GetService("ContentProvider")
local success, errorMsg = contentprovider:PreloadAsync(instanceTable)

if success then
    print("They're all loaded")
else
    warn("Image preload failed.",errorMsg)
end

What does it print?

#9

“Image preload failed. nil”

How do I fix this?

#10

I assume you added your roblox ids to the table right?

#11

Yes, I am.

There, the table I am using.

local preloadIDTable = {15155878931,15155878775,15155878627,15155878476,15155878186,15155877918,15155877678,15155877510,15155880841,15155880635,
	15155880502,15155880374,15155880168,15155880025,15155879813,15155879610,15155879477,15155879346,15155879164,15155882850,
	15155882651,15155882341,15155882156,15155881878,15155881576,15155881401,15155881172,15155880983,15155883237,15155883016,
	15155885884,15155885644,15155885384,15155885133,15155884953,15155884781,15155884483,15155884200,15155884038,15155883887,
	15155883603,15155888031,15155887806,15155887609,15155887413,15155887245,15155887106,15155886885,15155886691,15155886524,
	15155886083,15155890200,15155889946,15155889781,15155889593,15155889425,15155889205,15155889028,15155888868,15155888570,15155888327,15155890385,15155978828
}
#12

Could you try just this code and see if they even load at all?

for i,v in pairs(preloadIDTable) do
	local succ, errFail = pcall(function()
		game:GetService("ContentProvider"):PreloadAsync({asset})
	end)
	if succ then
		print("finished loading "..v..".")
	else
		warn("ID"..v.." could not load due to "..errFail)
	end
end
print("done")
#13

Every assets can’t be loaded with the same error.

“ID… could not load due to Unable to cast double to Content”

I am starting to get it now.
Does it need to be string?

#14

I’m not sure, but you could try that.

EDIT:
Or maybe add rbxasset in front of it.

for _, assetID in ipairs(preloadIDTable) do
    local assetString = "rbxassetid://" .. tostring(assetID)
    local success, errorMsg = pcall(function()
        game:GetService("ContentProvider"):PreloadAsync({assetString})
    end)
    
    if success then
        print("Finished loading " .. assetID .. ".")
    else
        warn("ID " .. assetID .. " could not load due to " .. errorMsg)
    end
end

print("Done")
#15

Every assets are printed as finished loading, however it’s still flickering.

#16

Did you try my edit code? With the rbxasset in front?

#17

Yep, I tried. But it’s still flickering.

#18

Maybe add a wait?
Like 10 seconds or 15 seconds after the done is printed, then use them ingame

#19

Still not working, I wonder why.

Here’s the video of it.
