Consegui combinar dois vídeos em um único vídeo com uma sobreposição lado a lado e consegui aumentar a taxa de quadros de um filme, mas não consigo descobrir como fazer os dois. Eu tentei o seguinte.
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
Meu problema é que o output2.avi tem todos os frames acelerados, mas o final do tempo comprimido reproduz o último quadro para o que seria a duração da versão não acelerada.
o vídeo normal acelerado leva 20 minutos de reprodução e dá 3 min no arquivo de saída.
lado a lado, dê 3 minutos de vídeo disparado e 17 minutos do último quadro no arquivo de saída.

Resolvido o problema Eu não estava aumentando a velocidade de reprodução do áudio. removendo o -map 0: um comando Eu recebo o vídeo sobreposto acelerado até a hora correta, mas sem áudio. Se eu quisesse ter áudio, eu teria comandos casdade atempo até conseguir uma velocidade de reprodução igual ao do vídeo, pois o máximo que vai subir é de 2,0 por um passo
