  • Other interesting software

    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • How to create a video from a series of images with varying image durations ?

    2 septembre 2014, par user1354557

    I’d like to programmatically create a video file that is composed of a series of images. However, I’d also like to be able to specify a duration for each image. I often see ffmpeg examples suggested for similar tasks, but they always assume the same duration for each image. Is there an efficient way to accomplish this ? (An inefficient solution might be setting the frame rate to something high and repeatedly copying each image until it matches the intended duration)

    I will be dynamically generating each of the images as well, so if there is way to encode the image data into video frames without writing each image to disk, that’s even better. This, however, is not a requirement.

    Edit : To be clear, I don’t necessarily need to use ffmpeg. Other free command-line tools are fine, as are video-processing libraries. I’m just looking for a good solution.

  • FFmpeg, slideshow : How to animate video based on the image sizes ?

    9 décembre 2019, par ArmKh

    I need to animate the video based on the image sizes. For example :

    1st images sizes are 600x1200px. In this case, I need to animate the video from the top of the image to bottom

    2nd image sizes are 1200x400px. In this case, I need to animate video from the right of the image to left

    The more pictorial video example is this

    So, is there any way to do it ?

  • Use ffmpeg to pan right over an image and then pan left to the original location

    4 février 2024, par user1517922

    I'm using this command to pan to the right for 5 seconds on an image (like a 1080x1080 window moving across a larger image, 500px from the top) :

    


    ffmpeg -loop 1 -r 30 -i image.jpg -vf crop=w=1080:h=1080:x=n:y=500 -frames:v 150 -pix_fmt yuv420p -preset fast -crf 30 video.mp4

    


    I'd like to pan back to the left for 5 seconds to end up at the same spot.

    


    The desired affect is when the video is on loop the square window pans right for 5 seconds then back left for 5 seconds then repeats, smooth and without flicker.

    


    I suspect I need to use zoompan, but I haven't had success trying that.
