  • Transition effects between images using ImageMagick and FFMPEG [closed]

    7 mai 2013, par user1599914

    I'm trying to generate a video using still images. I'm using Image Magick's convert command to duplicate the images.

    convert screen6.png -duplicate 10 -background black -gravity center -extent 1024x576 4%06d.screen.transition.png

    I then use ffmpeg to encode the images.

    Problem 1 : How can I achieve good transition effects between the images ; effects such as circle in, box out, wheel, as well as kenburns effect.

    Problem 2 : How can I overlay the images with text, and make that text to animate or appear with some effects such as fade in, zoom out.

    Your help will be greatly appreciated.
