Kodi ndingatani kuti ndibwezeretse WMV ku M4V popanda kuwononga mtundu wa kanema?

Ikani fayilo yanu ya WMV ndipo wosintha amayendetsa CRF-based re-encode yoyang'anira kutulutsa kwa M4V (CRF 18 mosalekeza, matanthauzo ochepa = fayilo yayikulu / yapamwamba). Codec imasankhidwa kuti igwirizane ndi M4V - H.264 kwa MP4 yokhala ndi kutalika, H.265 kwa MKV yokhala ndi kukula, VP9 kwa WebM, AV1 kwa ma pipelines atsopano.

Kodi ndi codec iti ya video yomwe M4V imagwiritsa ntchito?
