https://yadi.sk/d/6KLR2YqcZkUnj - вот кадры, из 45 Мб файлов png получается видео 604 Кб. Как кодирую:

ffmpeg -start_number 0000 -i 'frame%4d.png' -s 1920x1080 -vcodec libxvid -qscale 8 -me_method full -mbd rd -flags +gmc+qpel+mv4 -trellis 1 -threads 0 Гроза.mp4

Получается нормально, но слишком быстро. Вот бы сделать 5 или 10 кадров в секунду... Что дописать? Пишу "-r 10" - а он всё равно делает 30 кадров в секунду, скипнув 2/3 картинок.

О_о Я в шоке. А avconv что-то не хочет...

Скачайте статический ffmpeg, avconv уже давно значительно отстает от него.
