Eu tenho uma sequência de arquivos .png e estou tentando convertê-los em um filme. O problema é que quando eu tento convertê-lo para o formato avi, o ffmpeg diz "pedaço muito grande" :.
Estou executando o comando:
ffmpeg -f image2 -i imagens% d.png -vcodec libx264 -preset veryslow -crf 22 -threads 0 output_video.avi
Como eu corrijo para que eu tenha um filme que funcione com o PowerPoint?
Eu passei por tentar vários esquemas de codificação e referi-me a:
Formato de vídeo universal sem perdas para o comando inicial.
