Cov tub txawg ntau kom nws vim nws zoo xws li cov video conversion ceev nta ntaub, DVD ntaub ntawv conversion rau HD yeeb yaj duab, hlawv cov yeeb yaj duab rau hom ntawv DVD, download tau hauv internet yeeb yaj duab, luas vdeos, zoo zoo video, etc.
Kauj ruam 1: Ntshuam qhov ntaub ntawv H.265 rau lub converter
UniConverter rov rau conversion ntawm H.265 los H.265 yeeb yaj duab tso ua ntej tshaj. Koj yuav luag & xa cov ntaub ntawv H.265 lossis nias lub khawm "Ntxiv cov ntaub ntawv" rau import H.265 ntaub ntawv rau conversion cias. Thaum batch conversion ntawm ntaub ntawv H.265, xaiv tej yeeb yaj duab ntau los yog luag & tee yeeb yaj duab uas ib tug los ntawm ib tug. Yog hais tias koj yuav tau import ntawm mobile li iPhone, hauv tes lossis lwm tsav nyuaj, cia li nyem qhov tus nco cia icon nyob ib sab mus ncaj qha mus thauj khoom los ntawm pab kiag li lawm.
Kauj ruam 2. Xaiv tus tso zis ntau hom ntawv li hom ntawv tej ntaub ntawv H.264
Nyob rau hauv lub tso zis ntau hom ntawv tais, koj yuav pom ntau tabs. Mus nrhiav tus yees duab tab thiab xaiv ib yam video hom, xws li MP4, MOV, AVI, etc. Sab xis ntawm txhua hom, yog ib qhov icon, nias rau ntawd thiab lub poping nce qhov rais mus encode tsev koom yuav tshwm. Los yeej muaj, hloov cov encoder li H264. Koj kuj muaj cai hloov lwm encoder nqis raws li koj xav tau.
Kauj ruam 3. Hloov ua lwm yam H.265 los H.264
Ua ntej yuav pib conversion ntawm H.265 ntaub ntawv rau H.264, xaiv tau cov ntaub ntawv lo lus uas peb ceev txuag koj qhov rais PC los Mac ntawm "Tshuab raj > xum > chaw". Tom qab ntawd, xaiv "Siv" los yog "Hloov tag nrho" khawm rov conversion txoj H.265 rau hom ntaub ntawv ntawv H.264. Conversion txheej txheem yuav pib tam sim ntawd. Nws yuav tsuas siv ob peb feeb ntawm koj lub sij hawm, tom qab uas koj yuav txaus siab rau cov yeeb yaj duab nyob rau hauv tej dais. Qee zaus, nws yuav siv sij hawm ntau rau batch conversion ntawm H.265 ntaub ntawv. Koj yuav tau hloov koj yees duab converted rau koj li mobile ntawm hloov feature nrog USB yooj yim.
