Convertir des images en vidéo

Question

J'ai quelques images dans le dossier. Je veux convertir toutes les images en vidéos. Mais le problème est que lorsque la résolution est différente, elle montre l'erreur. Je ne veux pas étirer les images dans la vidéo. Je veux juste garder la taille de l'image telle qu'elle est. Mais il montre cette erreur.

mon commandement:

ffmpeg -framerate 1/3 -pattern_type glob -i "images/*.jpg" -i trinity.MP3 -shortest -c:v libx264 -r 30 -vf "scale=iw*sar:ih , pad=max(iw\,ih*(16/9)):ow/(16/9):(ow-iw)/2:(oh-ih)/2" -aspect 16:9 -pix_fmt yuv420p out.mp4 -y

Est-il possible de garder la résolution telle qu'elle est et une vidéo de toutes les images?

Answer 1

En supposant que vous voulez redimensionner toutes les images pour se loger dans une toile de 1280x720, utilisez

ffmpeg -framerate 1/3 -pattern_type glob -i "images/*.jpg" -i trinity.MP3 
     -vf "scale='if(gt(a,1280/720),1280,-1)':'if(gt(a,1280/720),-1,720)':eval=frame, 
      pad=1280:720:(ow-iw)/2:(oh-ih)/2,setsar=1" 
     -c:v libx264 -r 30 -pix_fmt yuv420p -shortest -y out.mp4
