  • Phantomjs - frames missing for animation

    3 janvier 2017, par sam

    I am using phantomjs to generate screenshot from a d3 animation and then merge the screenshots to create a video using ffmpeg. I am using the phantomjs render method to create series of screenshot. But when render method is used, I have to make the d3 animation extra slow so that all animation is captured smoothly. Even then, there seems to be frames missing. the animation doesnt look that smooth.

    So I came across another method, renderBuffer which I saw in the documentation of phantomjs. But this method, when tried to execute, even the example code wont execute. I was hoping renderBuffer could solve the missing frame issue.

    Anyone else facing similar issue or any methods you guys could suggest to attain smooth continuous frames ?

  • Import png files and convert to animation(.mp4) in R

    13 mai 2020, par Arthur

    I'm trying to create a short animation with several png files in R. I tried package magick but it only works when I save them to .gif. When I tried to save as .mp4, it will generate an .mp4 file but once you open it, only the first image will be shown.

    



    My code is

    



      library(magick)
  productPath <- ('/Users/abc/Desktop/products/')
  list <- list.files(productPath, '*.png')
  imagesPath <- paste0(productPath, list)
  images <- image_read(imagesPath)
  animation <- image_animate(images, fps = 20, loop = 1)
  image_write(animation, paste0(productPath, 'test.mp4'))


    



    I found there is also a package called animation, but I don't really know how to import png files with that package. Any solutions ? With either package should be fine. Thank you !

    


  • ffmpeg animated gif overlay, animation starts before specified 'between'

    18 janvier 2021, par Dave Thorn

    I am adding an animated gif as an overlay to a video with a command like this :

    


    ffmpeg -y -i video.mp4 -i overlay.gif -filter_complex "[0:v][1:v] overlay=38:11:enable='between(t,1.35,15.042000)'" -pix_fmt yuv420p -c:a copy -safe 0 output.mp4

    


    In that command I'm asking it to show the gif from 1.35 to 15, and that works insofar as the overlay is only shown between those times, but it's as if the animation starts before it reaches 1.35, because the bit of the animation before that point doesn't ever appear on the screen. The start of the animation is missing from the final video.

    


    Tried in ffmpeg-20180925-a7429d8 and ffmpeg-N-100581-ga454a0c14f
