WMV ukuba AVI Imibuzo Ebuzwa Rhoqo Ngokuguqula

Ndiyiguqula njani ikhowudi i WMV ibe yi AVI ngaphandle kokulahlekelwa umgangatho wevidiyo?

Layisha phezulu ifayili yakho WMV kwaye umguquli uqhuba i-CRF-esekelwe kwakhona-ukukopela ukujolisa kwi-visually-lossless AVI imveliso (CRF 18 ngokumiselweyo, amaxabiso aphantsi = ifayili enkulu / umgangatho ophezulu). I-codec ikhethiwe ukuhambelana ne AVI isiqulathi seefayili — H.264 ye-wide-compat MP4, H.265 ye-size-efficient MKV, VP9 ye-WebM, AV1 ye-newer pipelines. I-WMV ihambisa i-Microsoft VC-1 okanye i-WMV3 yevidiyo ngesandi se-WMA — ii-codecs azikho nto ngaphandle kweWindows ikhupha ikhowudi ngokusemthethweni. Iifayili ze-AVI zingaphambili kunee-codecs ezitsha: lindele i-MPEG-4 Inxalenye ye-2 (DivX/Xvid), i-Motion JPEG okanye iifayili ezingenakucothayo ezingenakucothayo kunokuba i-H.264.

Nantoni na exhomekeke kukubeka isiqhagamshelanisi esikhethekileyo siphelile emva koko. I-AVI ayinakuxhaswa kwe-codecs ekutsha, i-frame rate etshintshayo, izihloko ezimfutshane ezimdaka okanye iifayile ezingaphezulu kwe-4 GB ngaphandle kwe-hacks, kwaye i-chunk nganye i-overhead ikhupha ifayili.

Ingaba kukho incopho eguqula phakathi kwefomati ezimbini ezidala njenge WMV ne AVI?

Ukuba nje inxalenye ekhethekileyo yezixhobo ifuna injongo.
