Eu já escrevi sobre isso em Linux com Intel (Usando a GPU para renderizar vídeo) e depois em Linux com NVIDIA (Renderizando as fotos da GoPro em vídeo mpeg4 com ffmpeg e NVIDIA).  Agora eu testei como fazer isso no MacOS.

E deu muito certo.

O comando e saída foram esses:

$ ffmpeg -r 1 -i G%04d.JPG -c:v h264_videotoolbox -b:v 5M -pix_fmt yuv420p output.mp4

O que fez a mágica aqui foi o parâmetro "h264_videotoolbox".  Juntei 4626 imagens JPEG da última pedalada que fizemos em um vídeo de pouco mais de 1 hora.  E agora vou trabalhar em cima pra fazer o vídeo no formato adequado, trilha sonora e tamanho menor.
