M4V kuya WMV Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiyiguqula kanjani i-M4V ibe yi-WMV ngaphandle kokulahlekelwa umgangatho?

Layisha phezulu i-M4V ifayela futhi umguquli wethu ufaka i-CRF-based re-encode ebhekisa ku-visually-lossless WMV output (CRF 18 ngokuzenzakalela, phansi = enkulu / inhle). I-codec ikhethiwe ukufana ne-WMV container — H.264 / H.265 / VP9 / AV1 ngokufanele.

Yini i-codec esetshenziswa yi-WMV?

Kuxhomekeka ku-container. MP4 iphutha ku-H.264 (usizo lokudlalwa olubanzi kakhulu); MKV iphutha ku-H.265 nge ~50% ihele elincane ngekhwalithi efanayo; WebM iphutha ku-VP9 noma AV1 (ukusabalalisa kwe-web mahhala). Ungacima ukhetho lwe-codec ezinketho eziphezulu ngaphambi kokusebenza kokuguqulwa kwe-WMV.

Ingabe umsindo wami uzohlala M4V kuya ku WMV?

Yebo — umsindo uphinde uhlukaniswe lapho M4V no WMV bebelana nge-codec yomsindo, noma uphinde uhlukaniswe ku-AAC / Opus / Vorbis ngokuya ngomsebenzi oxhaswa yi WMV. Umsindo we-multi-track (umbono, izilimi ezihlukile) ugcinwa ezimbonini ezixhasa (MKV, WebM, MP4).

Ingabe ngigcina ifreyimu yesikhathi sangempela isuka ku M4V iye ku WMV?

Ngephutha i-framerate ayishintshiwe (M4V 24fps ihlala 24fps ku WMV). Uma ufuna ukuyishintsha (isibonelo, interlaced 29.97 kuya ku-progressive 30fps) i-framerate option iphatha 3:2 pulldown ne-deinterlacing ku-pass efanayo — akukho kuqala kokukhishwa kwekhodi okudingekayo.

Yini ushintsho lobukhulu behele phakathi kuka M4V no WMV?

I-codec efanayo ephinda i-muxes (H.264 ku M4V kanye no WMV) ikhiqiza ubukhulu obufana kakhulu. Ushintsho lwe-codec lungashintsha izinto ngokuphawulekayo: H.264 -> H.265 ngokuvamile ihlukanise ihele ngengxenye ngomgangatho ofanayo wokubona; H.264 -> VP9 ifana kakhulu; AV1 manje iyincane kakhulu ngezindleko zesikhathi sokuqoda esihamba kancane.

Ingabe ihele WMV lidlalwa ku-iPhone / Android / Smart TV?

MP4 / H.264 idlala kuwo wonke amadivayisi. MOV / H.264 idlala kumadivayisi we-Apple namanye ama-Smart TVs kodwa hhayi ku-Android edlule. MKV idinga i-VLC ku-iOS. I-WebM idlala kuma-browser kodwa hhayi kuma-Smart TV apps amaningi. I-"idivayisi ehambisanayo" esethelwe phambili ezindaweni eziphezulu zokukhethwa yenza i-codec / ibhokisi eliphephile kakhulu lenjongo yakho.

Ingabe kuthatha isikhathi esingakanani ukushintsha ihele lehora elilodwa M4V libe WMV?

Kuxhomekeka kushintsho lwe-codec. I-codec efanayo yoku-mux: 30-60 imizuzwana (akukho uku-coda kabusha). Ukuphinda u-coda ku-codec eyahlukileyo: ngokuvamile 0.3-0.7x isikhathi somthombo ku-GPU yethu, ngakho-ke ihora elilodwa M4V -> WMV liphele ngemizuzu engu-18-40; i-AV1 yoku-coda kabusha i-2-3x ihamba kancane.

Yini isixazululo esiphezulu esixhaswe yi M4V kuya ku WMV?

Kuze ku-8K (7680x4320) ku-Pro. I-Free ifinyelela ku-4K ngemikhawulo yobukhulu befayela. I-HDR metadata (HDR10, Dolby Vision) igcinwa lapho i M4V ne-WMV izihlungi ne-codecs zixhasa khona; ama-SDR asuka ku-SDR.

Ingabe i-M4V video yami imfihlo ngesikhathi sokuguqulwa kwe-WMV?

Yebo — amafayela wevidiyo alayishwe phezulu aqhubekelwa phambili abasebenza ngokuzimela futhi asuswa ngaphakathi kwemizuzu yokuqedwa. Akukho kuhlolwa komuntu, akukho ukugcinwa ngaphandle kwefasitela elibhalwe phansi. Bona /privacy/.

Ingabe ngizoqhakaza noma ngizilungise ngesikhathi sesiga-nyezi M4V kuya ku-WMV?

Akunakwesinye isikhashana — sebenzisa /video-trim/ noma /video-cutter/ ukucisha i-M4V kuqala, bese ufaka i-M4V -> WMV ukuguqulwa. Ukucisha-ke-ukuguqula kushesha kunakuphinde ukuguqula ihele lonke ukuze ugcine i-output.

Kungani ihele WMV limnyama uma kuqhathaniswa nomsuka M4V?

Kuyinto evamile kakhulu ukumiswa kwe-bitrate-too-low. Ukunconywa kabusha kwe-bitrate ephezulu M4V ibe yi-bitrate ephansi WMV ku-CRF ejwayelekile kucindezela izimo ezinamandla zokuhamba kakhulu. Thola i-CRF ngezansi ku-16-18 (noma hlela i-bitrate ecacile) bese uqala kabusha ukubuyisela ukhwalithi.

Ingabe i-M4V kuya ku-WMV isekela izihloko ezingezansi?

Yebo — amabhayisikobho afakwe ngaphansi kwesihloko (mov_text ku-MP4, SRT / ASS ku-MKV, WebVTT ku-WebM) agcinwa uma ama-M4V nama-WMV amabhokisi axhasa lawo. Amabhayisikobho afakwe ngaphakathi (ama-hardsub) adluliselwa ngokuzenzakalela ngoba yingxenye yedatha ye-pixel.
