Espaço de cores incorreto do FFmpeg com legendas codificadas

Problema

Eu tenho um arquivo MKV que tem 1 vídeo e 1 fluxo de legenda, do qual desejo codificar o fluxo de legenda e gerar um arquivo MP4.

Normalmente eu faço o seguinte ao codificar as legendas:

ffmpeg -i "original.mkv" -filter_complex "subtitles='original.mkv':si=0" -pix_fmt yuv420p -c:v libx264 -crf 18 "output.mp4"

Mas desta vez me deu um resultado indesejado :

O que eu gostaria de ver é o resultado desejado , semelhante ao que estou vendo no Aegisub:

Neste ponto, estou supondo que possivelmente tenha algo a ver com diferentes espaços de cores ou formatos de pixel e/ou não usá-lo corretamente com o ffmpeg. Como não estou muito familiarizado com isso, peço ajuda.

Notas Adicionais

Eu codifiquei tanto com o FFmpeg quanto com o Handbrake, ambos dando resultados diferentes enquanto codificava com configurações semelhantes. Como o Handbrake usa FFmpeg sob o capô, não esperava um resultado diferente em relação às legendas, mas aparentemente o Handbrake deu o resultado desejado.

Legenda

A legenda ASS incorporada contém a entrada YCbCr Matrix: TV.709, então acho que corresponde ao BT.709espaço de cores do vídeo.

Eu tentei valores diferentes para pix_fmt, ou adicionar -filter:scom colorspacesfiltros, mas sem sorte até agora.

Como parece não haver diferenças aparentemente significativas em mediainfo, estou um pouco perdido sobre o que está causando a coloração incorreta. Qualquer ajuda é apreciada.
