  • ffmpeg-python outputs black screen when trying to save as mp4

    3 mars 2023, par Saya

    This is my code. I am trying to make a video out of all pictures in the pics2 directory using ffmpeg.

    


    import subprocess

command = 'ffmpeg -framerate 1 -i "pics2/Image%02d.png" -r 1 -vcodec libx264 -s 1280x720 -pix_fmt yuv420p Output.mp4'
p = subprocess.call(command, shell=True)


    


    This saves an Output.mp4 successfully but the video has no frames (It is completely black)

    


    How do I solve this ?

    


  • Overlaying one video on another one, and making black pixels transparent

    25 janvier 2023, par Michael A

    I'm trying to use FFMPEG to create a video with one video overlayed on top another.

    



    I have 2 MP4s. I need to make all BLACK pixels in the overlay video transparent so that I can see the main video underneath it.

    



    I found two ways to overlay one video on another :

    



    First, the following positions the overlay in the center, and therefore, hides that portion of the main video beneath it :

    



        ffmpeg -i 1.mp4 -vf "movie=2.mp4 [a]; [in][a] overlay=352:0 [b]" combined.mp4 -y


    



    And, this one, places the overlay video on the left, but it's opacity is set to 50% so at least other one beneath it is visible :

    



    ffmpeg -i 1.mp4 -i 2.mp4 -filter_complex "[0:v]setpts=PTS-STARTPTS[top]; [1:v]setpts=PTS-STARTPTS, format=yuva420p,colorchannelmixer=aa=0.5[bottom]; [top][bottom]overlay=shortest=0" -acodec libvo_aacenc -vcodec libx264 out.mp4 -y


    



    My goal is simply to make all black pixels in the overlay (2.mp4) completely transparent. How can this be done.
