Yuav ua li cas kom hloov MPEG-4 los siv iSkysoft AAC
Kauj ruam 1: Ntxiv cov ntaub ntawv MPEG-4 lub Converter
Pib txoj conversion tuaj lub converter hauv koj lub computer. Tos yog import cov ntaub MPEG ntawv uas yuav tsum tau tom. Rau cov neeg siv Mac, koj yuav import tau ntau qhov ua ntaub ntawv thov uas zoo yog txhaj "Ntawv" thiab mam li khawm "Load Media ntaub ntawv". Rau qhov rais PC, ntaub ntawv yuav muab ntxiv rau qhov kev pab cuam los ntawm txhaj khawm "Ntxiv cov ntaub ntawv". Koj yuav tau import cov ntaub ntawv nyob rau hauv ob xyuas hauv computer los ntawm txoj kev luag thiab nco. Koj ntxiv tau ntau li ntaub ntawv raws li koj xav kom lub conversion.
Kauj ruam 2: Xaiv AAC thaum koj tso zis ntau hom
Rau qhov "hom ntawv tso zis" khawm, nyem lub hom ntawv tab mus saib daim ntawv teev cov zis tawm tswv yim uas yog txaus siab. Vim AAC yog ib lub hom, nias lub khawm "Lub" thiab ces xaiv AAC xaiv teev. Koj muaj peev xwm hloov lub chaw encoding ntawm cov ntaub ntawv rau cov zis los txhaj "Cov ntaub ntawv" khawm thiab ces mus rau qhov "Encode nqis". Koj yuav tau nias lub iav icon thiab hloov koj tej chaw ntawd.

Kauj ruam 3: Hloov MPEG-4 rau AAC
Thaum tau hloov qhov chaw, koj yuav tsum tau xaiv ib lo lus uas peb tau cov ntaub ntawv converted. Cia li nias rau hauv daim nplaub tshev txuag cov ntaub ntawv thiab ces ntaus khawm "Siv". MPEG-4 ntawv yuav raug kab y = x. AAC hauv pliag ntshis.

Nws kuj yog siv lub suab (videophone, xovtooj) thiab daim ntaub ntawv TV tshaj tawm hauv xov. Muaj ntaub ntawv MPEG-4. MP4 raws li tej ntaub ntawv ncua ntxiv. MKV muaj ib lub taub ntim cov ntaub ntawv ntawm MPEG-4. MPEG-4 muaj zog xws li khees me ntsis lawm coding efficiency ntawm MPEG-2, muaj peev xwm encode mixed media tej ntaub ntawv (yees duab, hais lus, thiab suab), yuam kev resilience txhawb robust kis thiab lub peev xwm INTERACTIONS with lub scene generated ntawm cov receiver.
