MOV → HLS

Ndikofunika, ndipo nthawi zambiri ndichifukwa cha kusintha. A MOV wophatikizidwa mu tsamba la webusaiti amasonyeza wosewera wowonongeka kapena kutsitsa, chifukwa masamba a browsers samapereka decoder kwa iye. HLS amasewera m'masamba mwanjira ya HTML5 video element popanda plugin ndi pulogalamu yakunja. HLS imasintha ku bandwidth ya woyang'anira nthawi yoyenera ndipo ndi yokhayo yokhala ndi mtundu wa Safari ndi iOS yothandizira.

Izi amasintha zimene kuyembekezera kuchokera kutuluka wapamwamba. Mmodzi wa mbali ya izi kusintha dzina encoding kuposa wrapper, kotero zimene zimabweranso ndi kuti bitstream m'matumba ameneyo amafuna bwino — nthawi zambiri MP4 kapena MKV. Kuwonjezeka kusonyeza m'matumba; codec ndi zimene inali kuika kukula kwa fayilo ndi kumene izo adzasewera.

Zomwe zimachitika nthawi zambiri sizotero. Ma conversions ambiri amasunga nyimbo imodzi, imodzi ndi ma channels ambiri (kapena ofanana), yosinthidwa kwa HLS wonyamula, kotero ma commentary ndi ma tracks ena a m'zinenero amatulutsidwa. AVI, WMV, MPEG, FLV, VOB ndi M4V kuti MKV amasunga ma track onse, ndipo zimenezi zimapangitsa MP4 kuti MOV. Kuti mutenge nyimbo ina, remux MOV ndi ma trackswo kawirikawiri (VLC kapena ffmpeg angachite izi), kenako asintha. HLS ndi HTTP Live Streaming ya Apple - si fayilo koma playlist komanso fayilo ya ma segments a media afupi.

Pa ena awiri. MP4 kuti MOV amasunga aliyense mawu subtitle track. AVI, WMV, MPEG, FLV, VOB ndi M4V kuti MKV kusamalira aliyense subtitle track: mawu subtitle ndi anaika kapena anasintha kuti SRT, ndi chithunzi-kugwirizana subtitle monga DVD kapena Blu-ray amene anaika monga iwo. MP4, MOV ndi WebM kuti MKV kusamalira kokha 1 subtitle track (monga ASS), ndi MP4 kuti WebM amasunga 1 monga WebVTT. Omwe awiri, kuphatikizapo MKV kuti MP4 kapena MOV ndi WebM kuti MP4, kugwa subtitle tracks, ndi wosinthira sadzawawononga mu chithunzi. Subtitles kuti kale anaika mu kukhazikika, chifukwa iwo ndi gawo la video frameworks.

MKV ndi yokha mainstream yokhala ndi ma fayilo ophatikizidwa (TTF fonts for ASS subs, JPG cover art, fan-translated PDF inserts). Kuchokera ku MOV kupita ku HLS kumachotsa ma attachments pamene HLS si MKV - ma streams elementary amasinthidwa, koma payload ophatikizidwa amakhala m'malo ochokera. Tengani MOV ngati chitetezo ngati mumatengera ma fonts ophatikizidwa.

Izi zimadalira HLS chonyamula. MP4, MOV ndi MKV zotuluka kugwiritsa ntchito H.264, amene amasewera pa pafupifupi aliyense foni, browser ndi TV. WebM zotuluka amagwiritsa ntchito VP9. AVI, WMV ndi MPEG zotuluka kugwiritsa ntchito zaka zambiri codecs amene mtundu anapangidwa kwa. HLS si fayilo yotsitsa imodzi - kuti ikhale yosagwirizana, iyenera kusinthidwanso kudzera mu chonyamula choyenera.

Palibe kugwiritsira ntchito HDR kapena kujambula ma tone. Mukangotsitsa kanemayo (MKV kupita ku MP4 kapena MOV ndi zosankha zoyambirira), HDR10 imapita mozungulira monga momwe ziliri. Mukasintha kanemayo, metadata ya HDR10 mastering imatha kugwa ndipo Dolby Vision kapena HDR10 + data siyimangidwa, ndipo ndi Quality, Resolution kapena Frame Rate setting ena a mabanja amachepetsanso kanemayo ku 8-bit color, kotero HDR MOV ikhoza kuwoneka yofiira mu HLS.

Kutengera pa zimene zimachitika kwa kanema. MKV kuti MP4 kapena MOV ndi default zoikamo amangosindikiza kanema stream unchanged, kotero kukula amakhazikika pafupi ndi bungwe. Ambiri ena awiri re-encode izo: a high-bitrate MOV nthawi zambiri amatuluka ochepa, pamene kale kwambiri compressed wina angagwiritse ntchito. M'lifupi File pansi Quality amapatsa ochepa zotuluka, ndi H.265 mu Codec kukhazikitsa (MP4, MOV ndi MKV) ndi nthawi zambiri ochepa kuposa H.264 pa quality yofanana koma amasewera pa zipangizo ochepa.

The Converter alibe mfundo yotchinga cap ya mfundo yake; malire ndi kutsitsa kukula kuloledwa pa dongosolo lanu, ndi 4K, 8K ndi 60 fps owona kusamalira mfundo zawo zotchinga ndi framerate ngati inu simungasinthe iwo. MKV kuti MP4 kapena MOV ndi default zoikamo alemba pa kanema mtsinje, amene ndi mosavuta pa chilichonse mfundo zotchinga. ena awiri re-encode pa CPU ndi nthawi imakula ndi pixel mnda, kotero m'mbuyo 4K kapena 8K wapamwamba amatenga nthawi yaitali kuposa nthawi yomweyo m'lifupi mu 1080p.
