panning and zooming multiple images with ffmpeg
16 mars 2017, par user1796752I have multiple images that I want to fade and zoompan for each image but when I do what others have said, the first image works perfect and the second is black. I want to have 25 images and the same thing occurs with every image black except the first one. I am sure I am missing something elementary. Please help.
ffmpeg -r .1 -i image_1.jpg -i image_2.jpg -vf "zoompan=z='min(zoom+0.0015,1.5)':d=125,fade=t=in:st=0:d=0.5,fade=t=out:st=4.5:d=0.5" -pix_fmt yuv420p output.mp4

FFMPEG : Converting WAV to MP4 with filter loops forever
30 juin 2021, par David FerrisI'm using the following basic
ffmpeg
commend to convert a WAV file to an MP4.

ffmpeg -i response.wav -s 1980x1080 -c:a aac -b:a 128k aNewVideo.mp4


This is great, however I'd like to include a black background on the mp4 file, and as it stands this doesn't add ANY background (see below).




I have tried to include the following filter to add this background, which works, however it loops forever, and when I stop it manually I get a file which is hours long with the first 20 seconds or so being my original audio.


ffmpeg -f lavfi -i color=c=black:s=1280x720:r=5 -i response.wav -s 1980x1080 -c:a aac -b:a 128k aNewVideo.mp4


How can I add this black background without running into this infinite loop problem ?
