Framerate: Chii Uye Sei Ichikosha?

by kim Updated: June 28, 2022

Paunoona bhaisikopo kana terevhizheni, kana kutamba mutambo wevhidhiyo, huwandu hwemafuremu anoratidzwa pasekondi imwe chete hunoratidza kuti iwo animation inoratidzika sei. Iyi nhamba yemafuremu pasekondi inozivikanwa se furemu, kana the. Izvo zvakakosha nekuti zvinogona kukanganisa zvakanyanya ruzivo rwako rwekuona. Nyaya ino ichatsanangura kuti chii furemu ndizvo uye nei zvakakosha mukugadzira midhiya, varaidzo, mitambo, uye mamwe maapplication.

Framerate inoyerwa mukati mafuremu pasekondi (FPS). Iyo yakakwira fps inowanzoreva animation yakapfava sezvo shanduko zhinji dziri kuitika sekondi yega yega. Framerate chinhu chakakosha kana zvasvika pakuona mafirimu, kutamba mitambo yemavhidhiyo uye chero zvimwe zviitiko zvinosanganisira kufamba pachiratidziri. Kana uchiona mabhaisikopo uye TV inoratidza, yakajairwa framerate ingave 24FPS kana 30FPS; yemitambo uye mamwe maapplication anoda kumhanya kwepamusoro chiitiko, akakwira mafrareti akadai 60FPS zvingasarudzwa.

Yepamusoro mafrareti inoda simba rakawanda rekugadzirisa iro rinogona kuwedzera sisitimu yekuremerwa nguva pamwe nekukupa iwe yepamusoro zviono; yakaderera furemu mareti anogona zvakare kuchengetedza zviwanikwa zvehardware zveGPU uye maCPU ekushandisa pane mamwe mabasa emutero senge AI kuverenga kana fizikisi simulations.

Chii chinonzi Framerate?

Furemu chiyero ndicho chiyero chekuti mafiremu mangani anoratidzwa pasekondi imwe chete mune animated kana vhidhiyo kutevedzana. Iyi ndiyo metric yakakosha kana zvasvika pakugadzira a smooth motion effect muanimation kana vhidhiyo. Kazhinji, iyo yakakwirira iyo framerate, iyo inotsvedzerera kufamba.

Muchikamu chino, tichaenda pamusoro pezvakakosha zve framerate uye tokurukura kuti nei zvakakosha.

Mhando dzeFramerates

Kunzwisisa marudzi akasiyana-siyana emafreyimu uye zvazvinoreva kune yako yekuona chiitiko kunogona kuve kwakaoma. Kune mashoma akasiyana marudzi emafrareti ekufunga nezvawo, uye imwe neimwe inopa mabhenefiti akasiyana kana zvasvika kune zvemukati mako. Kazhinji, iyo yakakwira iyo framerate, iyo yakapfava mufananidzo uchaonekwa pachiratidziro chako.

Mhando dzinonyanyozivikanwa dzemaframerates ndeaya anotevera:

• 24 mafuremu pasekondi (FPS) -Uyu ndiwo mwero wakajairwa weakawanda maficha mafirimu uye wakashandiswa kubva pamazuva ekutanga ekugadzirwa kwemafirimu. Inopa mafambiro emahara-emahara asi inoshaya maererano neruzivo nekuda kweiyo yakaderera furemu chiyero.
• 30 mafuremu pasekondi (FPS) -Izvi zvinowanzo shandiswa pazviratidziro zveterevhizheni uye mavhidhiyo ewebhu sezvo zvichipa kufamba kwakatsetseka uku uchichengetedza mazinga akanaka eruzivo. Iyo zvakare sarudzo yakakurumbira mumitambo yemavhidhiyo kwaunowanzo usingade anopfuura makumi matatu FPS yekutamba yakatsetseka.
• 60 mafuremu pasekondi (FPS) -Iine inodarika kaviri furemu chiyero kana ichienzaniswa ne24 FPS kana 30 FPS, izvi zvinowanzo shandiswa kukurumidza-paced chiito sequences sezvo ichipa kutaridzika kwakatsetseka kunoshamisa pasina kudzongonyedza kana jitters. Yakanakirawo kukurumidza kufamba sezvinhu zviri mumhando yepamusoro-soro inononoka kufamba mavhidhiyo anozonyatsotsanangurwa uye ari nyore kutevera pasina matambudziko.
• 120 mafuremu pasekondi (FPS) -Izvi zvinowanzo shandiswa chete kana kumhanya kwekutamba kuchidikanwa senge kunonoka kufamba kwepfuti kana yakakosha mhedzisiro yemifananidzo. Inobatsira kwazvo mukugadzira zvinokatyamadza zvinoonekwa zvinopa yakawedzerwa realism uye inonyudza yekuona ruzivo pasina jerkiness kana blurriness panguva yekutamba pane chero nhanho yekumhanya.

Zvakanakira Higher Framerates

High framerate inogona kubatsira munzira dzakawanda. Kune vaoni, inogona kuvandudza huchokwadi uye kutsetseka kweanimation, zvichiita kuti zvive nyore kutarisa zvinhu zvinomhanya kana mafambiro. Inobatsirawo kuderedza kusvibiswa kwekufamba uye kupa zvakapinza zvinoonekwa muzviitiko zvezviitiko kana uchitamba mitambo yemavhidhiyo.

Yepamusoro mafrareti anobvumira mamwe mafuremu pasekondi (the) zvinoreva kuti kufamba kwefuremu yega yega inoonekwa pachiratidziri yakapfava uye kucheka kwakatsetseka pakati pemafuremu kunogoneka. Izvi zvinoderedza kana kubvisa kutsemuka kunowanzoonekwa mukufamba kudiki. Iyo yepamusoro framerate inobatsirawo mifananidzo kuoneka yakajeka nekubhadhara motion blur uye ghosting (kusvibiswa kunokonzerwa nenguva yakareba yekuratidzwa).

Kune vanogadzira mafirimu, maframerates epamusoro anogonawo kupa zvakanakira senge kuwedzera kudzika kwemunda, zvichibvumira zvimwe zvakadzama zvinoonekwa kuti zvionekwe kure kure ne kamera. Iyi yakawedzera ruzivo inobvumira rusununguko rwakakura rwekugadzira paunenge uchigadzira mapfuti. Yepamusoro furemu mareti anogona zvakare kuderedza kuoneka nyaya dzimwe nguva dzinoitika nekuda kwekudzika mazinga echiedza kubva kunononoka shutter kumhanya kuri kushandiswa kubata mafambiro pazasi furemu mitengo.

Pakazere, kuve nekuwanikwa kwesarudzo yekupfura mune akakwira manhamba mafrareti kunopa vanogadzira mafirimu kutonga kukuru pamusoro pekuti nhanho yavo ichataridzika sei kana ichionekwa kumashure munguva-chaiyo uye saka inobatsira kune akati wandei maapplication izvozvi uye kufambira mberi mune ramangwana rekugadzira mamiriro.

Framerate Inobata Sei Hunhu hweVhidhiyo?

Furemu chiyero chinhu chakakosha chemhando yese yemavhidhiyo. Inotara nhamba yemafuremu anoratidzwa musekondi. Yepamusoro mafrareti inokonzeresa yakapfava, yakawedzera hupenyu-senge vhidhiyo. Iyo yakaderera framerate ichaita kuti vhidhiyo iite seyakaoma uye isina kutsvedza.

Muchikamu chino, isu tichatarisa kuti framerate inobata sei vhidhiyo mhando:

Framerate uye Motion Blur

Iyo framerate yevhidhiyo inoyerwa mukati mafuremu pasekondi (fps). Zvinokanganisa kujeka kwekufamba kunoonekwa uye kutsvedzerera kwese kwevhidhiyo. Iyo yakakwirira iyo framerate, iyo yakawanda mafuremu iwe yaunowana sekondi yega yega, zvinoreva kuti yakapfava uye yakanyatso ratidza yekufamba.

Motion blur chiitiko chinoitika kana chinhu kana munhu afamba nekukasika, achigadzira blur kana streak effect pascreen. Nehurombo, izvi hazviratidzike zvakanaka uye zvinoita kuti mavhidhiyo ako aratidzike akaderera. Zvichienderana nekukasira kuri kuita zvinhu mukati mechiitiko chako, iwe uchafanirwa kugadzirisa yako framerate zvinoenderana kuti uderedze kufambisa blur zvakanyanya sezvinobvira.

• Kune akawanda maapplication akadai mavhidhiyo emazuva ese uye kutenderera kwewebhu, 30 the inopa akawanda mafuremu pasekondi imwe chete uchichengetedza zvine musoro faira saizi.
• Kuwedzera yako framerate kuti 60 the zvichaguma nekunatsurudzwa kwekufamba blur asiwo akakura masaizi emafaira nekuda kwekupetwa kwemafuremu.
• Kune zviitiko zvinononoka kufamba kana mamiriro apo kurongeka kwakakosha senge nhepfenyuro yemitambo nemitambo, mamwe mavideographs anosarudza super high framerates kubva kusvika 240 the yezvinyoro zvinyoro zvishoma zvinofamba mapfuti - kunyangwe izvi zvichifanira kungoshandiswa kana zvichidikanwa nekuti zvinowedzera zvakanyanya saizi yefaira pasina kupa zvakakwana zvinooneka kuvandudzwa kwezvishandiso zvezuva nezuva.

Framerate uye Motion Artifacts

Furemu chiyero uye motion artifacts ndiwo mazwi maviri akakosha ekunzwisisa kana uchifunga nezvemhando yevhidhiyo. Motion artifacts reva kukanganisa kunoitika kana chiyero chevhidhiyo chakaderera pane chinodiwa kuratidza zvimwe zviito, kunyanya kukurumidza kufamba mumitambo uye zviitiko zvakaita sekarati. Kana kufamba kuchimhanya zvakanyanya kune iyo framerate, inogona kukonzera mutongi kana kusarira mumufananidzo izvo zvinoita kuti zviome kana kusakwanisa kunyatsoona chiito, zvichitungamirira kumufananidzo wakakanganiswa kana usina kukwana.

Pamusoro pekukonzera kukanganisa kwegraphical, yakaderera maforamu anogona kukanganisa mamwe maficha emhando yevhidhiyo nekudzikisa kupinza, kusiyanisa uye kupenya. Izvi zvinodaro nekuti yakadzika framerate inoreva kuti mamwe mafuremu anodiwa kuratidza zvinofamba zvirimo-zvichidzikisa kunaka kwekuona kwemunhu wega wega. Zvekutenderera zvemukati zvemukati zvinoonekwa pamakomputa monitors uye smartphones, mafrareti anofanirwa kuiswa zvishoma 30 fps (mafuremu pasekondi) kune zvinogamuchirika zvemafambiro ane masikirini akakura seanowanikwa paTV anobvumira pedyo 60 the kuitira kumiririra kufamba kwakatsetseka.

Izvo zvakakosha kuti vatengesi nevatepfenyuro vanzwisise mafambisirwo anoita zvinhu zvine chekuita nekutepfenyura vhidhiyo kuitira kuti vaone kuti mavhidhiyo anofambiswa zvakanaka kuitira kuti asaderedze kugutsikana kwevaoni. Kushandisa yakakwirira furemu mareti inobvumira vataridzi kunakidzwa nehupenyu hwehupenyu pasina kunyengedza kana kukanganisa kwemifananidzo uku uchideredza matambudziko ekubhafa ane chekuita neakadzika fps marongero. Nekunzwisisa kuti framerate inobata sei kunaka kwevhidhiyo, unogona kuita shuwa kuti mavhidhiyo ako anosvika kune vavanoda kuvateereri nenzira inonakidza uye isingaite.

Maitiro ekuvandudza maframerates

Furemu chiyero chinhu chakakosha kutariswa kana zvasvika pakutamba, video editing, uye kunyange kutenderera. Iyo yakakwirira iyo framerate, iyo inotsvedzerera chiitiko chichava chevaoni. Kuvandudza framerate kunogona kukubatsira kuti uwane kuita kwakanyanya kunze kwehardware yako.

Muchikamu chino, tichakurukura nzira dzakasiyana dzekuita wedzera framerate yako yekutamba zvirinani uye kutepfenyura:

Rongedza Kamera Settings

Kugadzirisa zvigadziriso zvekamera yako zvinogona kuvandudza zvakanyanya framerate yako, zvichikutendera kuti utore vhidhiyo yakapfava. Izvi zvinogona kubva pakubatidza high-speed mode senge 30 mafuremu pasekondi (fps) kugadzirisa zvigadziriso zvekuratidzira senge aperture uye shutter speed.

Iwe unofanirwawo kudzima chero kudzikamisa kwemufananidzo kana dynamic renji maficha ane kamera yako kuitira kuti uwedzere framerate. Uyezve, funga kupfura mukati RAW kana zvichibvira, izvo zvinobvumira mhando yepamusoro yekurekodha uye kugadzirisa pane echinyakare maJPEG mafomati.

Chekupedzisira, zvakakosha kugonesa ese aripo ekufamba blur mhedzisiro kana aripo kuitira kudzikisa mafambiro ekugadzira uye kugadzira yakapfava tsoka dzese:

• Gonesa zvese zviripo motion blur effects.

Shandisa Higher Quality Vhidhiyo Codecs

Kuti uwane yakanakisa framerate, zvakakosha kushandisa yepamusoro mhando vhidhiyo Codecs zvakaita se H.264, HEVC, VP9 kana AV1. Aya macodecs anokwanisa kupa huwandu hukuru hwemufananidzo uye odhiyo ruzivo uchiri kuchengetedza yakaderera bit rate. Izvi zvinobvumira iyo vhidhiyo feed kuti inyatsoita kana uchishandisa bandwidth uye zviwanikwa paPC yako uye inogona kubatsira kuwedzera kushanda zvakanyanya paunenge uchitenderera kana kurekodha.

Kunyange izvi zvingada mamwe mashandisirwo edata, iri mutengo mudiki kubhadhara kune yakavandudzwa kuita uye nani mufananidzo mhando. Uyezve, kushandisa epamusoro-mhando macodecs anogona zvakare kuderedza masaizi efaira sezvo vachikwanisa kudzvanya midhiya zvinobudirira pane yakaderera-mhando mafomati senge MPEG-2 kana DivX.

Deredza Vhidhiyo Resolution

Paunenge uchitsvaga kuvandudza yako framerate, chimwe chezvinhu zvekutanga kufunga ndechekuti kuderedza vhidhiyo yako kugadzirisa. Iyo yakadzikira resolution, iwo mashoma mapixels anofanirwa kubatwa neGPU yako neCPU, saka zvichibvumira kuwanda kwemafuremu pasekondi. Kudzikisa resolution kunogona kuvandudza zvakanyanya mafrareti mumitambo chero zvichiitwa mukati mechikonzero. Kudonhedza kure kunogona kukonzera chiitiko chisingatambwe kana kushomeka kweruzivo rwenyika yemutambo.

Imwe bhenefiti yekudzikisa vhidhiyo kugadzirisa kusunungura zviwanikwa zvehurongwa kune mamwe mabasa ane chekuita nekutamba sekumhanyisa mamwe maapplication panguva imwe chete. Izvi zvinogona kuderedza kupera kwese uye kuwedzera mashandiro pane akawanda maapplication pane yako system.

Pamapuratifomu ePC, zvigadziriso zvakasiyana zvinowanzo wanikwa mumamenu emitambo kana kuburikidza nekuratidzira mutyairi software (semuenzaniso AMD's Radeon software). Zvichienderana nekudiwa kwemitambo yako, kunyangwe kuseta nhanho imwe pasi kubva pane "yekuzvarwa" sarudzo kunogona kuita mutsauko (kureva, kana yako yemuno resolution iri 1920 × 1080, edza 800 × 600). Iwe unofanirwawo kukwanisa kuchinja anti-aliasing mazinga pano futi; chiyero chakanaka pakati pekuita uye graphical kutendeka kunofanirwa kusvikwa pakudzikisa kugadzirisa uye kudzikisa anti-aliasing mazinga zvakaenzana pamwe chete zvichienderana nekugona kwehardware.

mhedziso

Mukupedzisa, furemu chinhu chakakosha pakugadzirwa kwevhidhiyo. Zvinokanganisa maratidzirwo emifananidzo kune vanoona uye chinhu chakakosha pakuona mhando yekuona yenhau. Mazhinji mafirimu anopfurwa 24 mafaira kwechipiri, nepo mapurogiramu epaterevhizheni achiwanzotorwa 30 mafaira kwechipiri - kunyangwe izvi zvave kuwedzera kusvika 60 yematerevhizheni emazuva ano. Nekufambira mberi kwetekinoroji, maframerates epamusoro akadai se 120 FPS kana kunyange 240 FPS inogona kubatsira kune vaoni vanokwezva.

Paunenge uchisarudza yakakodzera kamera uye zvishandiso zvepurojekiti yako, zvakakosha kuti utarise yaunoda framerate sezvo iine yakadaro. kukanganisa kukuru pamhando yemufananidzo.
