Mafuremu ndiwo huwandu hwemifananidzo inoratidzwa pasekondi imwe. Ina dzaunosangana nadzo kakawanda:
Kwainobva 0.1%
23.976 = 24 × 1000/1001, uye 29.97 = 30 × 1000/1001. 1000/1001 iyoyo yakasara kubva pakuwedzera ruvara kuNTSC: kuti upinze ruvara usina kuputsa vakatambira nhema-ne-chena, chiyero chezvikamu chakatenderedzwa kubva ku 60 Hz kuenda ku 59.94 Hz (60 × 1000/1001), uye mafuremu akaenda pasi nawo.
Mhedzisiro: mafirimu anoonekwa pa 23.976 munzvimbo dzeNTSC panzvimbo pa 24. Kusiyana ndiko 0.1%, kana masekondi 3.6 pamusoro pewachi — zvisingaoneki pachezvake, asi usazvinyengedze ne 4% iri pasi apa uye usambosanganisa zvese mukubereka kumwe.
Kwainobva 4%
Nzvimbo dze PAL dzinoona pa 25 fps. Mafirimu anotorwa pa 24 fps uye anongotambwa pa 25 — hapana fomu rakawedzerwa kana kubviswa, saka kutamba kunomhanya 4% nekukasira (25/24 ≈ 1.0417). Firimu remaminitsi 100 rinomhanya maminitsi 96 muvhezheni ye PAL.
Iko ndiko kunobva kutsauka kunoenderera mberi: zvinyorwa zvakagadzirwa nechekare nevhidhiyo muvhezheni ye PAL zvinowirirana pakutanga uye zvakasiyana nemaminitsi mana pakeredhi. Hapana shanduro inogona kuchengetedza izvo; inofanira kugadziridzwa nechiyero.
Maitiro ekushandura
Kushandura zvinoreva kuwanza nechiyero chimwe chinoshanda pamusoro pemafirimu ese:
Kuziva zvaunazvo
Panzvimbo pekufungidzira chiyero, tsvaga nguva mbiri dzine nenguva kwayo yaunosimbisa — kazhinji mitsara yekutanga neyekupisira yehurukuro — uye udze chiridzwa "mutsetse uyu unofanira kuva pa 00:00:12 uye uyo pa 01:35:40"; inotambanudza firimu rese pakati pezvimbo zviviri izvozvo. Iko ndiko "two-point anchoring", uye hakudi kuverenga kwefuremu kubva kwauri.
Kuti usimbise huwandu hwefuremu iwe pachako, ongorora mutambi wako kana chiridzwa chekuvona ruzivo. Kana zita relfaira rakaita se `1080p.WEB` risina zano rehuwandu hwefuremu, two-point anchoring ndiyo nzira yakachengeteka.
Zviridzwa zvine chekuita nezvinotungamirira
Kushandura huwandu hwefuremu — Subtitle frame rate conversion; kugadzirisa kumhanya — Subtitle speed conversion; usina chokwadi kana kuri kutsauka kwese kana kutsauka kunoenderera mberi — Subtitles drifting further out of sync.
