Quais são os parâmetros do FFmpeg para o vídeo de codificação que se parece com as especificações?

Existe alguma maneira de codificar vídeo por essas especificações? (Main & nível 3.1 & ReFrames: subamostragem de 3 frames & Chroma: 4: 2: 0 , ... )

FFmpeg:

Stream #0:0: Video: h264 (Main), yuv420p(progressive), 768x576, 358 kb/s, 25 fps, 25 tbr, 1k tbn, 50 tbc
Stream #0:1: Audio: aac (LC), 48000 Hz, stereo, fltp, 49 kb/s
