blur

How to make this by using FFmpeg? Example without FFmpeg: Adobe After Effects Sony Vegas Pro I solved! ffmpeg -i input.mp4 -lavfi '[0:v]scale=ih*16/9:-1,boxblur=luma_radius=min(h\,w)/20:luma_power=1:chroma_radius=min(cw\,ch)/20:chroma_power=1[bg];[bg][0:v]overlay=(W-w)/2:(H-h)/2,crop=h=iw*9/16' -vb 800K output.webm Input: https://www.youtube.com/watch?v=17uHCHfgs60 Output: http://www.youtube.com/watch?v=CgZsDLfzrTs The accepted answer here takes forever to execute because it is doing so much unnecessary computation. We don't need to blur the pixels which we definitely know that will be out of

I want to be able to take an image and blur it relatively quickly (say in 0.1 sec). Image size would almost never be larger than 256 x 256 px. Do I have to loop thru every pixel and average them with neighbors or is there a higher-level way that I could do this? PS : I am aware that multiple box blurs can approximate a gaussian blur. I found a really fast pretty crappy way for iOS3.2+ apps UIView *myView = [self view]; CALayer *layer = [myView layer]; [layer setRasterizationScale:0.25]; [layer setShouldRasterize:YES]; This rasterizes the view down to 4x4 pixel chunks then scales it back up

I've worked on a fiddle to show the simple validation that I'm trying to do for my user ID field: Make it required (validate as aggressively as possible) Set a minimum length (validate as aggressively as possible) Set a maximum length (validate as aggressively as possible) Run an AJAX call to ensure user ID doesn't already exist ( I want to only run this on blur ) I'm not using the validate() - remote rule because I wanted to have a custom object returned instead of just a simple string. If that's possible with remote and it only calls the rule on blur, then I can try for that. (All of my AJAX

I am wondering if there is some way to apply a gaussian blur onto a div using jQuery (or CSS that jQuery can modify). I have looked into blur(), but at least with Safari, it doesn't seem that it accomplishes what I'm looking for. If possible, I want to use fadeIn on the effect, so it blurs gradually. Thanks for any help! Mickel Be aware that Blur is when a DOM-element, such as textboxes (inputs etc.) loses focus, and should not be mixed with the kind of blur you are talking about (gaussian/motion blur). There is no good cross-browser solution for this problem. You can, however, blur images by

I want to blur an image with GD library, unfortunately the GAUSSIAN_BLUR effect that GD gives isn't enough and i want something being more blurrish <?php $im = imagecreatefrompng($_GET['image']); if($im && imagefilter($im, IMG_FILTER_GAUSSIAN_BLUR)) { header('Content-Type: image/png'); imagepng($im); } else { echo 'fail'; } imagedestroy($im); I want something like this or at least near it. JKirchartz You can try convolution: $gaussian = array(array(1.0, 2.0, 1.0), array(2.0, 4.0, 2.0), array(1.0, 2.0, 1.0)); imageconvolution($image, $gaussian, 16, 0); $gaussian is a matrix, so mathematically

This question already has an answer here: How to use CSS (and JavaScript?) to create a blurred, “frosted” background? 9 answers Is it possible to code a div to enable it to blur whatever image is under it? something like this: Could this be done somehow with -webkit maybe? Dre Not with CSS on its own, but you can pull a similar effect off with Canvas and the StackBlurforCanvas library. See this UPDATE: Looks like backdrop-filter was recently introduced to Webkit nightly, so eventually we'll be able to do this with CSS only. Yay! Unfortunately this can't be done purely using CSS. Although
