Chomwe nambala iliyonse ili
Mtengo wa frame ndi zithunzi zingati zomwe zikuwonetsedwa mu sekondi imodzi. Zinayi zomwe mumakumana nazo kwambiri:
Komwe 0.1% imachokera
23.976 = 24 × 1000/1001, ndi 29.97 = 30 × 1000/1001. 1000/1001 imeneyo ndi zotsalira zowonjezera mtundu ku NTSC: kuti muchepetse subcarrier ya mtundu popanda kuswa olandira akale akuda-ndi-oyera, mlingo wa field udatsika kuchokera ku 60 Hz mpaka 59.94 Hz (60 × 1000/1001), ndipo mtengo wa frame udatsika nawo.
Zotsatira: mafilimu amawonekera pa 23.976 m'migawo ya NTSC m'malo mwa 24. Kusiyana ndi 0.1%, kapena 3.6 masekondi pa ola limodzi — osawoneka bwino paokha, koma musasokoneze ndi 4% pansipa ndipo musaphatikize ziwirizi mu nambala imodzi.
Komwe 4% imachokera
Migawo ya PAL imawonetsa pa 25 fps. Mafilimu amawomberedwa pa 24 fps ndipo amangoseweredwa pa 25 — palibe chithunzi chimodzi chowonjezedwa kapena kuchotsedwa, kotero kusewera kumayenda 4% mofulumira (25/24 ≈ 1.0417). Filimu ya 100-mphindi imayenda 96 mphindi mu mtundu wake wa PAL.
Umenewo ndio mizu ya kusiyana kowonjezereka: zilembo zing'ono zing'ono zopangidwa motsutsana ndi zoyambirira ndi kanema mu mtundu wa PAL zimafanana bwino pachiyambi ndipo zili mtunda wa mphindi zinayi pofika m'mabuku. Palibe kusintha kwapadziko lonse komwe kungapulumutse chimenecho; kumayenera kuchepetsedwa ndi chiŵerengero.
Momwe mungasinthire
Kusinthira kumatanthauza kuchulukitsa ndi chiŵerengero chimodzi chomwe chimagwira ntchito pa filimu yonse:
Kudziwa yomwe muli nayo
M'malo moganiza chiŵerengerocho, pezani nthawi ziwiri zomwe nthawi yake yolondola muli nayo tsimikizirani — nthawi zambiri mizere yoyamba ndi yomaliza ya zokambirana — ndipo auzeni chidachi "mzere uwu uyenera kukhala pa 00:00:12 ndipo umenewo pa 01:35:40"; imatambasula filimu yonse molunjika pakati pa mapointi awiri amenewo. Imeneyo ndi "two-point anchoring", ndipo sifuna nambala ya frame rate kuchokera kwa inu.
Kuti mutsimikizire mtengo wa frame nokha, yang'anani wosewera wanu kapena chida cha media info. Pamene dzina la fayilo monga `1080p.WEB` libe chidziwitso cha frame rate, two-point anchoring ndiyo njira yotetezeka.
Zida zogwirizana ndi malangizo
Kusinthira kwa mtengo wa frame — Subtitle frame rate conversion; kusintha kwa liwiro — Subtitle speed conversion; osatsimikizira ngati ndi offset yapadziko lonse kapena kusiyana kowonjezereka — Subtitles drifting further out of sync.
