Estou tentando codificar Um Lugar Silencioso... Sei que há subs forçados, mas ao tentar codificá-lo de 4K (nativo) para 4K (x265) ou 1080 (x264), os subs forçados não são queimados no arquivo resultante.
O mesmo comando funcionou bem com a gravação das legendas forçadas para outro filme. Quando eu uso o Handbrake, ele queima nas legendas forçadas.
Este é o comando que estou usando:
ffmpeg -y -probesize 2048M -analyzeduration 2048M -forced_subs_only 1 -i ../in/A Quiet Place.mkv -map 0:0 -map 0:1 -map 0:1 -c:v libx264 -preset slower -profile:v high -level 5.1 -crf:v 22 -vf scale=1920:-1 -x264-params ref=5:bframes=5:b_adapt=2:direct=auto:analyse=all:me=umh:merange=24:subme=10:trellis=2:vbv-bufsize=512000:vbv-maxrate=512000:rc-lookahead=60:colorprim=bt2020:transfer=smpte2084:colormatrix=bt2020nc -c:a:0 aac -ac 6 -c:a:1 ac3 -ac 6 -disposition:a:0 default -disposition:a:1 none ../temp/A Quiet Place - 1080p.mp4
Este é o meu arquivo mkv:

O que
-forced_subs_onlyfaz é dizer ao decodificador PGS para apenas decodificar subs marcados como forçados. Você precisa sobrepor esses subs, que são baseados em imagem, para que fiquem visíveis no vídeo de saída. Então,ffmpeg -y -probesize 2048M -analyzeduration 2048M -forced_subs_only 1 -i ../in/A Quiet Place.mkv -map 0:0 -map 0:1 -map 0:1 -c:v libx264 -preset slower -profile:v high -level 5.1 -crf:v 22 -filter_complex [0:v]scale=1920:-1[v];[v][0:s:0]overlay -x264-params ref=5:bframes=5:b_adapt=2:direct=auto:analyse=all:me=umh:merange=24:subme=10:trellis=2:vbv-bufsize=512000:vbv-maxrate=512000:rc-lookahead=60:colorprim=bt2020:transfer=smpte2084:colormatrix=bt2020nc -c:a:0 aac -ac 6 -c:a:1 ac3 -ac 6 -disposition:a:0 default -disposition:a:1 none ../temp/A Quiet Place - 1080p.mp4O filtro de sobreposição gravará as legendas forçadas do primeiro fluxo de legenda no vídeo. Dependendo do tamanho do quadro da legenda, você pode querer dimensionar esse fluxo antes de sobrepô-lo.
