  • FFMPEG : create movie from timestamped images

    28 mai 2017, par HyperDevil

    Im trying to make a small movie file from a folder with webcam images.

    They are named like this :
    00-00-38.jpg
    00-05-37.jpg
    00-10-37.jpg
    00-15-37.jpg

    H-M-S.jpg format

    Although i tried patterntype glob and simpler commands i cannot get it to work.

    This is what i tried :

    ffmpeg -r 1 -pattern_type glob -i '*.jpg' -scale=720:-1 -c:v libx264 out.mp4 
    
(got only one image)
    
ffmpeg -r 25 -i *.jpg -vf "scale=720:-1" output.mp4
    
(same size as a jpg file but no video)

    Console output :

    ffmpeg -framerate 1 -pattern_type glob -i "*.jpg" -vf scale=720:-1 -c:v libx264 -pix_fmt yuv420p out.mp4

  • ffmpeg screen blending mode makes transparent png pink

    28 janvier 2014, par gilad s

    I have a sequence of PNG files with transparency - I'd like screen-blend them on top of a video

    ffmpeg -i video.mp4 -i "Images/%03d.png" -filter_complex "blend=all_mode='screen':all_opacity=0.7" output.mp4

    the images are indeed merged on top of the video but with a pink overlay ?!

    I also tried to add "-vcodec png" and "-vcodec libx264" and to try a .mov video but got the same result.
