  • Overlay timelapse video on solid background colour using ffmpeg

    13 septembre 2020, par hamchapman

    I've got a load of screenshots of a homepage that are named homescreen000001.png, homescreen000002.png, etc and I'm trying to create a time-lapse video of these images using ffmpeg.

    



    I've got it working in general when I run the following :

    



    ffmpeg -f image2 \
       -i ~/Desktop/homescreen%06d.png \
       -r 0.5 \
       -s 1440x900 \ 
       -b:v 1M \
       -vcodec libx264 \ 
       -pix_fmt yuv420p \
       ~/Desktop/timelapse.mp4


    



    However, it turns out that some of the images have transparent backgrounds so the background is showing up as black on those images.

    



    I'd like a white background so I've been trying to set that up using ffmpeg as follows :

    



    ffmpeg -f image2 \
       -loop 1 \
       -i ~/Desktop/whitebg.png \
       -i ~/Desktop/homescreen%06d.png \
       -filter_complex overlay \ 
       -r 0.5 \
       -s 1440x900 \ 
       -b:v 1M \
       -vcodec libx264 \ 
       -pix_fmt yuv420p \
       ~/Desktop/timelapse.mp4


    



    Here whitebg.png is 2px x 2px png with a white background, and that's it.

    



    This ffmpeg command produces a really tiny (in file size) video that's just a white background.

    



    Can anyone explain how I can overlay the images as a time-lapse video over a white background using ffmpeg ?

    


  • Convert FLV video with alpha channel to PNGs with transparency

    8 octobre 2012, par AZAR

    I have some FLV videos with alpha channels, and I want to convert each of them to PNG images using ffmpeg but keep the transparency.

    So far, I've tried this :

    ffmpeg -i input.flv -an -y %d.png

    But this outputs the PNG files with black background.

    Is there any way to do this ?

    Alternate acceptable solution : If I can output the images and give the alpha channel a certain color of my choice. I can then remove it later via imagemagick and convert that color to transparency.
