FCP X: Tsim ib cov nyhuv Chroma-yawm sij (ntsuab-qho screen)

Chroma-yawm sij (kuj hu ua "ntsuab qho screen") los yog ib tug staple hauv video ntau lawm. Cov nyhuv no puas zoo li cas yog pub koj ua kom cov tom qab qab ib tug actor pob tshab ces koj yuav muab lub actor rau hauv ib cheeb tsam ntau dua ib lub studio.

PIB TAU

Ua ntej tshaj, qhov uas koj ua tau zoo rau hauv koj lub lag luam yog zoo li cas koj tua lawv. Ntawm no yog 7 cai yooj yim ntau lawm:

1. Lam yuav tsum muaj tsawg kawg yog 10 taw pem lub taub hau qhov screen ntsuab. Qhov no txhob pom los ntawm cov "spilling" nyob ib ncig ntawm lawv lub cev los yog lub xub pwg nyom keeb kwm yav dhau.
2. Feem ntau, tsis txhob nrum ntxoov ntxoo ntawm qhov screen ntsuab. Yuav shooting taw ceevfaj heev
.
3. Cov tom qab ntsuab yuav tsum du sai li sai tau. Xim lawm yeej yuav zoo dua ntaub; tsis txhob wrinkles thiab folds.
4. Cov tom qab ntsuab yuav tsum lit ntseeg nkaws, ntawm ob tog thiab saum toj mus rau nram qab side. Kuv yuav ua kom muaj cov tom qab ntsuab teeb rooj ntawm 40-50% theem ntawm qhov waveform saib.
5. Yog tsis muaj kev sib raug zoo li cas tom qab qhov no lit thiab li cas koj lam yog lit. Qhov tsab xov xwm no yuav illustrate ntawd.
6. Pom koj keeb kwm yav dhau los rau smoothness. Pom koj lam mus ua.
7. Tsis txhob txhawj txog qhov muaj tus keeb kwm yav dhau ntsuab sau tus ncej. Nws tsuas koos cov npoo ntawm koj lam kiag li. Mattes tej khoom siv nroj qua ntxi nyob ib ncig ntawm cov npoo.

QHOV NCE LUB NTSIAB

Qhov tshuaj ntsuam ntsuab duab yeej muab tso saum tus keeb kwm yav dhau. Koj yuav muab xws li cov ntsuab tshuaj ntsuam los yog tom qab duab rau hauv cov neeg Storyline. Kuv nrhiav nws yooj yim mus muab tus keeb kwm yav dhau los hauv xov Storyline, vim nws ua editing lub vijtsam ntsuab duab yooj yim. Tab sis qhov no yuav xaiv tej purely.

Xaiv cov kev tshuaj ntsuam ntsuab clip.

Los ntawm cov teebmeem Browser > double-click Keying qeb, nyhuv Keyer, uas yog siv rau cov xaiv clip. (Koj yuav kuj luag cov nyhuv tsaws rau saum qaum qhov clip, yog hais tias koj tsis nco qab xaiv seb qhov tshuaj ntsuam ntsuab clip ntej.)

Tsis txhob panic yog hais tias koj cov duab zoo li weird – peb yuav kho nws.

Nyem qhov qauv xim icon. Qhov no pub rau fine-tuning xaiv xim tom qab.

Nyob rau hauv cov duab ntsuab-vijtsam, luag yuav xaiv ib tug sawv cev ntawm ntu tus keeb kwm yav dhau. Kuv yuav ua kom tau ze ntawm koj lub ntsej muag, tab sis tsis li kaw tias kuv ntawd xaiv xoob plaub hau los tawv nqaij.

Koj qhov tseem ceeb yuav tsum tau saib zoo tam sim ntawd. Feem ntau, koj yuav zaum so no. Tiam sis muaj ntau peb lwm yam kev kho uas yuav ua rau koj qhov ua tseem ceeb twb zoo saib:

• Ntxuav tau cov matte
• Cov kev kho me ntsis ntug
• Muab lub teeb

Nyem lub pob Matte los tso saib koj qhov tseem ceeb li foreground dawb rau ib tug dub tom qab.

Koj lub hom phiaj yog tus tsim lub foreground khoom dawb, uas txhais tau tias yog opaque, thiab tus keeb kwm yav dhau khoom dub, uas txhais tau tias pob tshab. Kho lub teb thiab cov nyob deb li cas ntug sliders kom txog thaum twg koj cov khoom zoo. (Phem tiag tiag hauv lub lag luam, koj yuav tau mus yuav tau kho tsuas xaiv, hais nram qab no.)

Yog hais tias ib tug ntug yog ib yam nkaus thiab pronounced, los yog xav tau kev pab, nias lub hau icon.

Ces, nias thiab luag ib txoj kab ntawm cov foreground rau tus keeb kwm yav dhau los hauv lub Canvas. Luag tus nta slider (kuv cursor qhov twg) txog ntawm ntug zoo li qhov zoo tshaj plaws nws tau. Txawv video tawm tswv yim tsim no yooj yim (ProRes), lwm tus (HDV, AVCHD) thaum uas ua qhov no ntau nyuab dua. Perfection yog tsis-ua raws li koj muab tau.

Cuam phij zaum kawg muab plaub ntxiv tweaks rau nram qab lub taub lim keyer:

• Xaiv xim
• Lwm yam cuab yeej matte
• Txeej hluav
• Muab lub teeb

Thawj peb yog tsim los so tsis txhaj tshuaj tag daws – nyeem cov kev uas muaj FCP X pab ntaub ntawv mus kawm cov no ua li cas. (Kuv siv cov cuab yeej tsuas xaiv mus ntxuav tom tus yuam sij tsaus heev kuv siv ib qho piv txwv ntawm qhov tsab xov xwm no.)

Muab lub teeb, ho, yog aesthetic. Nws puas yog muab xim ntawm tus keeb kwm yav dhau cov npoo ntawm qhov foreground, ua tus yuam sij tag nrho saib ntxiv "organic," txhais tau hais tias tus foreground thiab keeb kwm yav dhau los tau rau qhov chaw qub.

Qhov no nws yog ib tug nyhuv hloov maj mam, tab sis txias heev.

Tig los qhwv teeb thiab tau kho tus nqi slider thiab saib ua li cas. Luag tus lwm sliders ncig thiab pom li cas. Qhov zoo tshaj plaws txog cov chaw no yog tias thaum nws zoo zoo rau koj, nws tseem zoo. Tus nqi ntawm cov nyhuv yog lig ntawm koj. Nco ntsoov, teeb qhwv tsuas raug rau cov npoo ntawm qhov foreground thiab yuav tsum siv zog.

Thaum koj ua tas, koj muaj ib tug yawm suab yawm sij looking!

SO COV DUAB NROG RAU IB LUB HNAB KHIB NYIAB

Tej zaum, tsis tas li ntawd, koj tsis muaj, ah, kab tias, qhov zoo ntsuab-npo duab mus ua hauj lwm nrog. Ntawm no, xws li, muaj cov teeb seev hauv lub foreground, nrog ib heev tab lit ntsuab tshuaj ntsuam nyob hauv keeb kwm yav dhau. (Xyu... no yog pitiful xwb.)

Thaum twg koj rho tus yuam sij – uas yog zaj duab xis-hais lus tau tsim thiab lis ntsuab-npo txhaj tshuaj, raws li kuv tau piav los saum no – thiab nws nrhiav tau Nyobzoo li, yuav ib kauj ruam ntxiv: muab ib matte yam tsis siv lawm los rhuav tshem tag nrho cov khib nyiab lwm tus koj lam.

Koj yuav tau koj qhov tseem ceeb saib zoo li koj yuav – uas qhov no tsis zoo li txhua – luag lub npog ncauj nyhuv (teebmeem > Keying > npog ncauj) nyob saum lub vijtsam ntsuab clip.

Faj seeb: Lub npog ncauj nyhuv yuav tsum nco ntsoov muab ntxiv tom qab cov nyhuv Keying, kom lub npog ncauj yog hauv qab ntawm Keyer rau cov neeg soj ntsuam.

Tom qab ntawd, luag txhua lub voj plaub los ua ib tug zoo xws tias koj foreground duab yog muaj nyob hauv nws, thiab txhua yam koj yuav tau tshem tawm cov tseem nyob nraum zoov. Ntawm no, xws li, peb tshem tawm txoj kev muag zaub lub teeb, ntawm ntug rau tom qab ntsuab thiab cov tearing rau saum tus duab. Kuv twb nrhiav tau no npog ncauj nyhuv xwb zoo dua thaum koj yuav ib clip connected.

Tiam sis, qhov loj npaum ntawm lub npog ncauj nyhuv yog tias yav tag los koj tsuas muaj plaub ntxiv rau kev ua hauj lwm nrog. Uas yog qhov twg ib nyhuv dawb los nyob hauv, uas tso cai rau koj los ua daim deb li saj zawg zog nrog nws. Nws yog sau los ntawm Alex Gollner thiab muaj nyob rau ntawm nws lub website – alex4d.wordpress.com/fcpx/ – kuv kom koj nws los mas.
