That's a 10, not a Q.
It looks like a Q because the small hand is passing over that spot and compression makes it blurry.
Watch the video again tards.
That's because you don't understand compression and interpolation.
Your picture is larger than it should be given the video's native resolution which means it has been upsampled and compressed again when you saved the screenshot as a jpeg. The specific upsampling algorithm used depends on the device, software you were watching the video with.
The camera is moving the whole time the clock is visible which basically means some detail is lossed vs if the camera was stationary.
Twitter also compresses the shit out of video content, if you could find a higher quality video posted elsewhere chances are you would get a different result.
Pics attached are three random frames taken at the video's NATIVE resolution.
4th pic is megazoomed using nearest neighbor, notice the 0 turns into a rectangle, kinda.
Essentially what you're suggesting is Q having fine grained control over the compression of the video after it was uploaded to Twitter but don't mind me, chase your fairy tales.
