Adding a rotating effect on an image using ffmpeg ? [closed]
5 mai 2024, par GarryI'm trying to overlay an image on a video, and add subtle rotating effects for that image, left, right, left right, and so on. (see pictures) The rotation works, however the edges are always very jagged and bad quality.
Is there a way to improve my filters, or is there a better approach that I can use, without jagged edges ?

ffmpeg -loop 1 -i image.png -i video.mp4 -t 10 -filter_complex "[0:v]scale=720:720:flags=lanczos,fps=25,format=rgba,rotate=0.05*sin(2*PI*t/4):c=black@0:ow=round(iw*1.5):oh=round(ih*1.5)[rotated];[1:v][rotated]overlay=(W-w)/2:(H-h)/2:shortest=1" -c:v libx264 -crf 16 -preset veryslow -c:a copy -y output.mp4


But the edges turn out to be very jagged :
