• Where can I find high-quality videos for testing video processing ?

  15 novembre 2018, par Workman

  Aside from Big Buck Bunny, Sintel, and Elephant’s Dream, what are other high-quality and free sources for high quality video ?

  I’m using these videos internally to test video transcoding options and am not public redistributing. Any suggestions for content that falls under this category ?

• How to compare images to find the least blurry image ?

  31 octobre 2022, par Frezzley

  How to compare images to find the least blurry image ?

  



  I want to automaticallz generate an image/thumbnail from a video.

  



  I use ffmpg for that.

  



  However once in a while the image is totally blurred and I want to get rid of the blurry images.

  



  My idea was to create multiple images per video and than compare the images to eachother.

  



  Now the question :

  



  Is there a way to compare the blurryness of images ?
