Ubuyobozi bwuzuye kugirango bugufashe kumva neza uburyo bwiza bwo kuyobora.
Gusobanukirwa Gukemura Video na Bitrate
Gukemura amashusho bigena umubare wa pigiseli yerekanwe kuri ecran, bigira ingaruka itaziguye kandi igaragara neza. Imyanzuro isanzwe ikubiyemo 720p (1280×720), 1080p (1920×1080), na 4K (3840×2160). Imyanzuro ihanitse itanga amashusho atyaye ariko bisaba cyane umurongo mugari hamwe nimbaraga zo gutunganya. Kubintu byinshi bigenda neza, 1080p itanga uburinganire bwiza hagati yubuziranenge nibikorwa. Bitrate igenzura umubare wamakuru akoreshwa kumasegonda ya videwo, apimwa muri kilobits kumasegonda (kbps) cyangwa megabits kumasegonda (Mbps). Hejuru ya bitrate ibika amakuru menshi agaragara, igabanya ibihangano byo guhunika nka pigiseli na blurriness. Ariko, bitrate ikabije irashobora gutera ibibazo kubireba hamwe na enterineti itinda. Urufunguzo ni ugushakisha uburyo bwiza bwa bitrate kugirango ukemure intego yawe ikomeza ubuziranenge mugihe ukina neza gukina muburyo butandukanye bwihuta. Isano iri hagati yo gukemura na bitrate ningirakamaro mugutsinda intsinzi. Umugezi wa 1080p mubisanzwe usaba 3000-6,000 kbps kugirango ube mwiza, mugihe imigezi 720p ikora neza kuri 1.500-4,000 kbps. Uru rutonde rushingiye ku bwoko bwibirimo – ibintu byihuta cyane nkimikino cyangwa siporo bikenera bitrate kurenza uko bihagaze neza cyangwa videwo yo kuvuga.
Igenamiterere ryiza ryamajwi yo gutemba
Ubwiza bwamajwi bugira ingaruka cyane kubareba, nyamara akenshi birengagizwa mugushiraho amashusho. Audio bitrate yerekana neza nubukire bwijwi mumigezi yawe. Kubintu byinshi bigenda neza, 128-320 kbps itanga ubuziranenge bwamajwi idakoresheje umurongo mwinshi. Inzira yibanda kumuziki yungukira kuri bitrate yo hejuru (256-320 kbps), mugihe ibirimo amajwi gusa bikora neza kuri 96-128 kbps. Igipimo cyintangarugero hamwe nubujyakuzimu nibintu byingenzi byamajwi bigira ingaruka kumiterere. Igipimo cya 44.1 kHz hamwe nuburebure bwa 16-biti bihuye na CD nziza kandi ikora neza mugutemba. Igenamiterere ryo hejuru nka 48 kHz / 24-bit bitanga iterambere ryimbere ariko byongera ubunini bwa dosiye. Amahuriro menshi atemba ahita akora amajwi, bityo kwibanda kumurongo uhoraho hamwe nubuhanga bwo gufata amajwi akenshi bifite akamaro kuruta ubuhanga bwihariye.
