    Hey I have been working with a 2D cricket game, when the bowler through the ball then the ball is become very blurry and not clear, It is seems 3 shadow clone like motion blur, I want to fix this issue, tried so many ways to fix, like using post processing motion blur component, FixedUpdate, fixed frmae rate. But none of those fixed my issue.

    So is there any expert in this Unity community who can help me.

    I am sharring some images, and possible video capture below

    This again? It's your monitor, all LCD panels have some level of ghosting and this will be maximized when you have a while object on a black background.

    This is not something you can fix in your game, Unity itself isn't blurring anything and no frame in the YouTube video ever shows any ghosting when paused.

    Try using a different background 5hat doesn't have such high contrast with the ball.

    I don't know how I can make you understand. Watch the video you posted and pause it: the image doesn't look blurred when the video is paused, which means the video itself doesn't contains any motion blur, it's an artifact of the display itself.

    Just play any game or video with fast movement and you'll see it too.

    white ball moving fast on black background, what to say

    as someone already said, if you cant pause on a frame with artifact then it doesnt exist

    if you can only catch it by filming your screen, then its because of the screen

    if you still are not convinced, find a video of a white ball moving fast on a black background that you think looks good and post that as example of what your are striving toward


    it might sound funny, but the best solution would be to add real motion blur, to deceive your eye into making the movement look better

    You guys are not giving me solution instead giving me problem root cause which I already know. I asked for solution not for problem root cause.

    ye what we try to say is that there is no problem

    all graphics work like this, theres nothing that you can do to stop it

    some workaround:

    add a ton of detail, dont make high contrast shapes ( white movement on black background is very bad )
    reduce speed, increase framerate, if you make it 120fps it will look better

    bonus:
    show video of a game you want to copy, to analyze and try to copy the secrets they used to make it look good

    Your solution is to buy a better monitor that doesn't blur.

    Next!!

    Use one of the many tests here to check your monitor: https://www.testufo.com/ghosting

    As above, the solution is to purchase a better monitor. It's nothing to do with Unity and certainly isn't a 2D issue.

    And please don't send unsolicited DMs to devs about this as you did to me. Please read the community code of conduct regarding this:
