So i just notice my Macbook Air M4 screen is flickering like flashlight while i play this video on youtube

(only this Godzilla video https://www.youtube.com/watch?v=5BxqahE0fu8 i don't seen any video happend like this yet),

first i thought is because browsers but when i try to download this video and play again this issue is still happend

if this isolated to this one Video...(?)

I would suspect some corruption with that one video. Try a differnt source, a different video— contact the author of the video...(?)

I do not see how that is a Mac or macOS issue.

When you attempt to play a video, flickering indicates frames had to be dropped.

If playing directly off the internet, this can be caused by a multitude of problems, including that your Mac can not get the data fast enough. What is the speed shown for an Internet speed test?

if the downloaded video is played, was it stored on the fast BOOT drive or a slower external drive? Is that drive fast enough?

If none of those apply, I defer to leroydouglas suggestion that the file may be inherently damaged, or possibly not compressed properly so that it can be automatically un-compreseed and displayed in real-time with todays decompression Codecs.

if you think there might be things running in the background on your Mac that are causing this video to play too slowly,

Consider downloading and running this little "discovery" utility, Etrecheck. It changes NOTHING. Etrecheck was developed by a senior contributor here, and uses mostly system calls and simple tests to collect often-needed information.

it contains little tests for speeds of devices, CPU utilization, memory usage, energy usage and a digest of recent problems, in one easy to use package. it does not even need to be Installed. Because less can be learned when your Mac is running great, best time to run is when your problems are actually occurring, if possible.

if you follow the directions faithfully, its report (pre-laundered of all personally-identifiable information) can be "Shared" to the System ClipBoard, then Pasted into an ‘Additional Text’ window in a reply on the forums.
