WebM kuya AC3 Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiyikhipha kanjani i-audio track kusuka ku-WebM njenge-AC3?

Layisha phezulu ihele WebM futhi umguquli ususa umsindo osuka kwi-WebM, bese uguqula ikhodi ibe yi-AC3. Amafreyimu wevidiyo asuswa — akukho sikhathi sevidiyo sesibili, akukho phutha lomgangatho ngaphandle kokukhishwa kwe-AC3 codec.

Yiyiphi i-track yomsindo ekhishwayo uma WebM yami iqukethe eziningi?

Ngephutha umsindo 0 (umsindo wokuqala, ngokuvamile umsindo omkhulu). Uma WebM wakho ufaka umlayezo, ama-dubs, noma umsindo ochazayo kuma-tracks angeziwe, umkhethi othuthukisiwe "umsindo" ukuvumela ukuthi ukhethe 1, 2, 3... ngokucacile.

Ihele AC3 lisebenzisa i-bitrate enjani?

Iphutha AC3 i-bitrate yi-192 kbps (icacile kuma-earphones amaningi). Nciphisa ku-320 kbps nge-audiophile output, noma 96-128 kbps ngezwi/podcast lapho ihele elincane liyisisekelo. Ama-AC3 angeke alahlekile (WAV, FLAC) agweme ukumiswa kwe-bitrate futhi agcine yonke isampula.

Ingabe ukusuka ku WebM kuya ku AC3 kuzonciphisa ubunjani bomsindo wami?

Uma i AC3 ifomethi ingekho lutho (WAV, FLAC, ALAC), yonke isampula yangempela igcinwa. Uma i AC3 ingekho lutho (MP3, AAC, OGG, Opus), i-codec icindezela futhi — ku-192 kbps ushintsho alukwazi ukulizwa kuningi kwezithameli; ku-96 kbps ungalizwa ama-cymbals noma ama-sibilans abandayo. I-WebM i Container ayinaso isikhundla kulolu hlelo — ukumiswa kwe-codec kuphela okubalulekile.

Ingabe i-AC3 ekhishwayo igcina i-WebM isilinganiso sesampula?

Ngokungagqibekanga yebo — 48 kHz WebM umsindo ushintsha ube 48 kHz AC3 umsindo, 44.1 kHz ushintsha ube 44.1 kHz. Uma ufuna ukuncipha kwesampula ukuze kusebenze (isibonelo 96 kHz studio masters kuya ku 44.1 kHz CD-quality AC3) isampula-rate dropdown yenza lokhu ngekhwalithi ephezulu yokusatshalaliswa kabusha.

Ingabe kuthatha isikhathi esingakanani ukukhishwa kwe AC3 kusuka ku-WebM wehora elilodwa?

Umsindo demux + transcode usebenza ngokushesha kakhulu kunakhodi yevidiyo - ngokuvamile 5-15% yesikhathi somthombo. Ihora le-1 WebM -> AC3 liphele ngemizuzu engu-3-9 ku-pipeline ejwayelekile. Uma i-AC3 codec ifana ne-source codec esekwi-WebM (ejwayelekile ye-AAC ngaphakathi kwe-MKV / MP4), iyi-remux ecacile futhi isebenza ngemizuzu.

Ingabe ihele AC3 lifaka isihloko / umculi / amathegi we-albhamu?

Uma ihele WebM ligcina i-stream metadata (umculi, isihloko, i-album), sikopa lezi zindawo kuAC3 isitoreji lapho ifomu lixhasa amathegi. ID3v2 (MP3), amazwana we-Vorbis (OGG, FLAC), ama-MP4 atoms (AAC / M4A), RIFF INFO (WAV) wonke abhalwe. Ukungabi nathegi WebM kwenza AC3 — sebenzisa i-Mp3tag noma i-Picard emva-kwe-ukukhishwa ukuze uthuthukise.

Ingabe WebM yami imfihlo ngesikhathi sokukhipha umsindo?

Yebo — imodeli yobumfihlo efanayo nezo zonke iziguqulo. Umsuka WebM nesokudla AC3 zicutshungulwa kubasebenzi abahlukanisiwe futhi zicishwe ngaphakathi kwemizuzu. Asikwazi ukudlala, ukugcina, noma ukuhlanganisa okuqukethwe. Bona /privacy/.

Kungani i-AC3 yami ithola izithuba ezingenalutho noma umsindo ongelungile?
