Ndinogona here kuchengeta kuratidzwa kwechifananidzo, kana kumanikidza zvakajeka zviyero?

Izvo zvinoitika. MPEG (MPEG-1/2) ndiyo DVD uye kutumira kupararira: yakaoma uye universally decodeable, asi zvakaoma kupfuura zvakaoma per bit kupfuura H.264. Izvi zvinotora sarudzo yekuti kana kudonha kwefaira kuri chete nyaya yepixels kanawo nyaya yekudzokorora kudzokorora.
Pane chimwe chinhu chine chekuita ne MPEG ini ndingadai ndakatarisa?

Yeah — MPEG-1/2 uses a program stream rather than a modern index, so cuts are aligned to GOP boundaries unless the picture is re-encoded. Kuongorora kunokosha usati wachinja saizi yefaira iwe hauzove nechokwadi chekudzoreredza.

Zvinoenderana nekuti kana basa richida kudzokororwa kwekodzero. Maitiro anongobata chete chigaro kana nguva inoitwa sekopi yemvura uye vhidhiyo inowanzova nebit-identical kune iyo nzvimbo. Chii chaunoda kudzokorora maframes chinoenda kuburikidza ne x264/x265 pamhando yemhando iwe yaunosarudza, uko CRF 23 inoratidza zvakajeka pane akawanda mavhidhiyo.
