  • build video from images with a bash for loop using ffmpeg

    10 septembre 2021, par TheCodeNovice

    I am trying to take 50K images and turn them into a movie using ffmpeg. I am running this on a HPC setup, hence the slurm commands. My attempt does not work since I am running into a hard limit due to the shear volume of images. I cannot just list a start number since the pipeline will reject some images so I do not have a proper sequence.

    


    I know a loop could circumvent both issues but I am not sure how to use that with ffmpeg so that it builds one long movie.

    


    The cat command has worked for shorter movies but i just have too many images now.

  • FFMpeg is writing a matplotlib animation with diminishing quality

    3 mars 2017, par Bryan Stafford

    I am trying to create a bunch of animations that follow the paths National Hockey League teams travel during the current season. Currently, my animation looks like this.

    As you can see, the animation begins decently sharp but within 2 seconds the quality bottoms out and everything is grainy.

    The relevant code is this :

    ani = animation.FuncAnimation(fig, update, frames=len(all_x + 20), 
    
                              interval=75, repeat=False)
    
filepath =  map_team + '.mp4'
    
ani.save(filepath, writer='ffmpeg', fps=30)
    
plt.tight_layout()
    
plt.show()

    I have chosen FFMpeg as my writer because I hope to put about 30 graphics online and the MP4 format keeps each file around 1.5MB. If there’s a way to keep the graphics sharp, with low file sizes, and able to be uploaded onto Imgur, I would love to do that with my project.

    Thanks.
