AVI kuya AAC Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiyikhipha kanjani i-audio track kusuka ku-AVI njenge-AAC?

Layisha phezulu ihele AVI futhi umguquli ususa umsindo osuka kwi-AVI, bese uguqula ikhodi ibe yi-AAC. Amafreyimu wevidiyo asuswa — akukho sikhathi sevidiyo sesibili, akukho phutha lomgangatho ngaphandle kokukhishwa kwe-AAC codec. AVI Microsoft Audio Video Interleave, isungulwe ngo-1992 phezu RIFF chunk format - eyodwa yezinto eziphilayo ezidala kakhulu okwamanje e circulation.

Ingabe ukushintsha AVI kuya ku AAC kuyingxenye yesithathu yokucindezela okulahlekile?

Yebo, futhi kufanelekile ukuhlela. Izifomethi zombili ziyi-lossy, ngakho-ke i-AAC encoder isebenza kusuka kumsindo osele udlulele engxenyeni eyodwa ye-psychoacoustic, futhi iziphakamiso zayo zihlanganisa isiqephu sokuqala. Ku-192 kbps noma ngaphezulu, imiphumela ihlala icacile kakhulu. Uma une-lossless master nganoma yikuphi, uku-encoding i-AAC kusuka kulo kunciphisa ukudlula okuphindiwe ngokuphelele. Amafayela we-AVI adlule ama-codecs amanje: cabanga i-MPEG-4 Part 2 (DivX/Xvid), Motion JPEG noma amafreyimu amnyama angacindezelwa ngaphandle kwe-H.264.

Ingabe ukusuka ku AVI kuya ku AAC kuzonciphisa ubunjani bomsindo wami?

Uma i AAC ifomethi ingekho lutho (WAV, FLAC, ALAC), yonke isampula yangempela igcinwa. Uma i AAC 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-AVI i Container ayinaso isikhundla kulolu hlelo — ukumiswa kwe-codec kuphela okubalulekile.
