Мне удалось объединить два видео в одно видео с наложением бок о бок, и мне удалось увеличить частоту кадров для фильма, но я не могу понять, как сделать то и другое. Я попробовал следующее.

ffmpeg -i gp1.mp4 -i gp2.mp4 -filter_complex "[0:v]setpts=0.077*(PTS-STARTPTS),    pad=iw*2:ih[bg]; [1:v]setpts=0.077*(PTS-STARTPTS)[fg]; [bg][fg]overlay=W-w-10:0:shortest=1[out]" -map "[out]" -map 0:a -c:v libx264 -crf 19 output2.avi

Моя проблема в том, что output2.avi имеет все ускоренные кадры, которые он воспроизводит нормально, но в конце сжатого времени он воспроизводит последний кадр в течение продолжительности не ускоренной версии.

нормальное ускорение видео занимает 20 минут воспроизведения и дает 3 минуты в выходном файле.

бок о бок дают 3 минуты ускоренного видео, затем 17 минут последнего кадра в выходном файле.

Решил проблему, я не увеличивал скорость воспроизведения звука. удаляя -map 0: команда, я получаю ускоренное видео до нужного времени, но без звука. Если бы я хотел иметь аудио, я бы использовал команды casdade atempo, пока не достигну соответствующей скорости воспроизведения, так как максимальная скорость воспроизведения видео составляет 2,0 за один шаг.
