Coj piv txwv rau cov yeeb yaj kiab uas zoo tshaj, uas muaj pua pua hauv lub network. Daim duab rau nws yog upside down, uas tsis yog ib txwm yooj yim.
Ib hom yeeb yam uas muaj duab ntxig rau ...
Kom pib, khiav VirtualDub thiab qhib lub yees duab rau hauv. Yog tias tsis muaj qhov yuam kev (yog tias muaj - qhov laj thawj feem ntau hauv cov codecs, saib saum toj sau nyob rau hauv tsab xov xwm), ua qhov chaw nyob hauv Seem Lus:
- Direct Stream Copy (ncaj qha luam ntawm suab khiav tsis hloov).
Tom ntej no, mus rau cov yeeb yaj duab tab:
- teev tus nqi ntawm Kev Ua Haujlwm Tag Nrho (tag nrho cov ua video);
- ces qhib lub lim tab (Ctrl + F - shortcuts).
Xovxwm ADD Lim khawm thiab koj yuav pom daim ntawv loj loj ntawm cov ntxaij lim dej: txhua tus lim tau npaj rau qee yam hloov duab (trimming sawv, hloov kho, thiab lwm yam). Ntawm tag nrho cov ntawv no, koj yuav tsum nrhiav ib lim nrog lub npe Tig thiab ntxiv nws.
VirtualDub yuav tsum qhib lub qhov rais nrog qhov chaw ntawm cov lim: ntawm no koj tsuas xaiv ntau npaum li cas degrees koj xav tig cov duab video. Hauv kuv kis, kuv muab nws 90 degrees rau sab xis.
Ces cia li nias thiab saib seb daim duab pauv hauv VirtualDub (qhov rai qhov kev zov me nyuam tau muab faib ua ob ntu: tus thawj ib daim ntawv qhia txog daim duab yees duab, qhov thib ib: dab tsi tshwm sim rau nws tom qab tag nrho cov kev hloov).
Yog hais tias txhua yam yog ua kom raug, daim duab nyob rau hauv ob lub qhov rai ntawm VirtualDub yuav tsum tig. Tom qab ntawd muaj cov kauj ruam kawg: xaiv cov codec los muag cov yees duab. Los xaiv ib lub codec, qhib cov Yeeb Yaj Vev Piav / Ntawv tab (koj tuaj yeem nias ntawm Ctrl + H tseem ceeb).
Feem ntau, lub ntsiab lus ntawm cov codecs yog heev kim heev. Nrov tshaj codecs hnub no yog Xvid thiab Divx. Rau video compression, Kuv pom zoo kom nyob twj ywm rau hauv ib ntawm lawv.
Ntawm kuv lub computer yog Xvid codec nyob rau hauv nws, thiab kuv txiav txim siab mus muag cov yees duab. Ua li no, xaiv qhov codec ntawm daim ntawv thiab mus rau nws qhov chaw (Configure button).
Zoo, ua tau nyob rau hauv qhov chaw ntawm lub codec, peb npaj cov video bitrate.
Bitrate (los ntawm lus Askiv bitrate) - ntau cov khoom siv los khaws ib qho thib ob ntawm cov ntsiab lus multimedia. Nws yog txoj kev cai kom siv cov kev ntsuas thaum siv cov kev xa cov ntaub ntawv xa tawm ntawm cov ntaub ntawv ntau tshaj ib txoj hauv kev, uas yog qhov tsawg kawg nkaus ntawm cov kwj deg uas cov kwj deg no tuaj yeem tsis qeeb.

Nws tseem tshua tsuas yog kom txuag tau cov yees duab: ua qhov no, nias F7 yawm sij (lossis xaiv Cov Ntaub Ntawv / Txuag li AVI ... ntawm daim ntawv qhia zaub mov). Tom qab ntawd, qhov encoding ntawm cov ntaub ntawv video yuav tsum pib. Lub sijhawm encoding yog nyob ntawm ntau yam: ntawm lub zog ntawm koj lub PC, nyob ntev npaum li cas ntawm qhov yees duab, uas cov ntxaij lim dej koj tau thov thiab cov chaw koj tau teev, thiab lwm yam.
Qhov tshwm sim ntawm duab yees duab yees duab tau pom hauv qab no.
PS
Yog, tau kawg, muaj cov kev pab cuam yooj yooj yim kom tig cov yees duab. Tab sis, tus kheej, Kuv xav tias nws zoo dua qub kom nkag siab VirtualDub thiab ua rau ntau qhov kev ua haujlwm video nyob hauv nws, tsis txhob daus thiab txhim kho ib qho kev pabcuam rau txhua txoj haujlwm (nrog txhua tus, los ntawm txoj kev, txheeb nws tawm thiab sijhawm rau nws).
Yog tag nrho, hmoov zoo rau txhua tus!
