MPEG-4 yog ib tug nrov hom ntawv rau feem ntau xov xwm players. Txawm li cas los, AAC muaj ib tug zoo lub suab zoo tshaj MPEG-4 thiab yog feem ntau siv thaum encoding lub suab tivthaiv video clips. Vim lub suab zoo, tej zaum koj yuav xav kom hloov MPEG-4 ntaub ntawv rau AAC rau playback rau koj cov suab players. Converting MPEG-4 mus rau AAC yog heev ua tau, thiab koj cia li xav tau ib tug npaum suab converter ua lub chaw ua hauj lwm. UniConverter yuav tau ib tug zoo xaiv, thiab xav paub ntxiv ntawm nws cov nta thiab hloov dua siab tshiab txheej txheem sib tham ntxiv nyob rau hauv no tsab xov xwm.
Qhov zoo tshaj plaws MPEG rau AAC Converter
Raws li xov xwm ntaub ntawv cov neeg siv, peb txhua tus xav tau ib lub cuab tam uas yuav hloov peb cov ntaub ntawv tsis muaj cov teeb liab ntsais nrog cov thawj zoo thiab muaj cov ua hauj lwm ua nyob rau hauv ib tug luv luv lub sij hawm. UniConverter yog, yog li ntawd, lub converter peb yog tag nrho cov nrhiav. Lub suab thiab video converter yog ib tug tag nrho cov nyob rau hauv ib tug lub cuab tam vim thaum siv nws koj kev pab los ntawm ntau zog.

Yuav ua li cas Hloov MPEG-4 mus rau AAC siv iSkysoft
Kauj ruam 1: Ntxiv rau qhov MPEG-4 Cov ntaub ntawv mus rau lub Converter
Pib hloov siab los ntseeg los ntawm pib lub converter nyob rau hauv koj lub computer. Cov tom ntej no yog import cov MPEG cov ntaub ntawv uas yuav tsum tau yuav tsum tau hloov dua siab tshiab. Rau Mac cov neeg siv, koj yuav import cov ntaub ntawv los ntawm txhaj rau cov "Cov ntaub ntawv" thiab ces tus "Load Media ntaub ntawv" khawm. Rau lub qhov rais PC, cov ntaub ntawv yuav muab ntxiv rau qhov kev pab cuam los ntawm txhaj rau cov "Ntxiv ntaub ntawv" khawm. Koj yuav tau import cov ntaub ntawv nyob rau hauv ob qho tib si computers los ntawm cov luag thiab nco txoj kev. Koj muaj peev xwm ntxiv li ntaub ntawv muaj ntau raws li koj xav rau cov hloov dua siab tshiab.
Kauj ruam 2: Xaiv AAC li koj cov zis hom
Nyob rau hauv "tso zis hom" khawm, nyem qhov hom tab mus saib daim ntawv teev cov zis tawm tswv uas txaus siab. Txij li thaum AAC yog ib qho suab hom ntawv, nyem qhov "Suab" khawm thiab ces xaiv AAC los ntawm cov uas muaj npe xaiv. Koj yuav tau hloov lub encoding tej chaw ntawm lub qhov zis ua ntaub ntawv thov los ntawm txhaj rau cov "Cov ntaub ntawv" khawm thiab ces mus rau "encode tej chaw". Koj yuav tau nias lub iav icon thiab hloov koj tej chaw los yeej muaj.
Kauj ruam 3: Hloov MPEG-4 mus rau AAC
Thaum koj ua tas hloov lub chaw, koj yuav tsum xaiv ib lo lus uas rau cov neeg ntseeg li cov ntaub ntawv. Cia li nias rau ntawm lub nplaub tshev rau txuag cov ntaub ntawv thiab ces ntaus lub "Hloov" khawm. Lub MPEG-4 cov ntaub ntawv yuav tsum hloov dua siab tshiab rau AAC nyob rau hauv ib luv luv lub sij hawm.
Lub tswv yim: MPEG-4 vs AAC hom
Yuav ua li cas yog MPEG-4 hom:
MPEG-4 yog hais txog ib tug compression txoj kev ntawm lub MPEG pab pawg neeg tsim los rau cov compression ntawm ob suab thiab digital media cov ntaub ntawv, tshwj xeeb tshaj yog rau bandwidth (tsawg tshaj li 1.5Mbit / sec bitrate, MPEG-4 muaj xws li ob qho tib si audio thiab video ntaub ntawv, thiab nws txhawb ntau A / V codecs. MPEG-4 cov ntaub ntawv yog feem ntau siv rau streaming yeeb yaj duab rau hauv Internet thiab rau faib video ntsiab lus tshaj lub web. Nws kuj yog siv nyob rau hauv lub suab (videophone, xov tooj) thiab tshaj tawm hauv xov TV daim ntaub ntawv. MPEG-4 cov ntaub ntawv muaj .mp4 raws li cov ntaub ntawv extension. MKV kuj yog ib tug cov ntaub ntawv ntim ntawm MPEG-4. MPEG-4 muab zog xws li khees me ntsis lawm coding efficiency ntawm MPEG-2, muaj peev xwm encode mixed media cov ntaub ntawv (video, kev hais lus, thiab suab), kev ua yuam kev resilience rau kev pab txhawb nqa robust kis tau tus mob thiab muaj peev xwm mus nrog lub suab scene generated ntawm lub receiver.
Yuav ua li cas yog AAC hom:
AAC hais txog Advanced Suab Coding nyob rau hauv tag nrho. Nws yog ib qho suab coding qauv rau lossy cov compression. Nws yog twb tsim tau lub successor ntawm MPEG-3 Txheej 3 (MP3). AAC yog lub neej ntawd standard suab hom ntawv rau iPhone, YouTube, iPod, iTunes, PlayStation 3 thiab ntau npaum li cas.
