FLV ku MKV Mafunso Ofunsidwa Kawirikawiri Okhudza Kusintha kwa Anthu
Kodi ndingasinthire bwanji FLV kupita ku MKV popanda kubwezeretsa kanema wa kanema?
+
Ngati ma kontena a FLV ndi MKV angagwiritse ntchito codec yomweyo (H.264, H.265, VP9, AV1), wosintha amabwerera ku remuxer: ma streams oyamba amakopedwa ndi byte-by-byte ku MKV kontena ndipo amasintha kokha. Remux ya 1 GB FLV ku MKV nthawi zambiri imatha m'masekondi a 5-15 ndi kuwonongeka kwabwino.
Kodi ma audio ambiri adzapulumuka kusinthidwa kwa FLV kupita ku MKV?
+
Ndikoyenera - zonse zolemba za audio mu FLV (kuwunika kwa woyang'anira, mabungwe osiyanasiyana, mawu ofotokoza) amasungidwa mu MKV pamene chikwama chofunikira chimathandizira ma audio ambiri. MKV ndi MOV amayendetsa ma audio osatha; MP4 amathandizira ambiri koma ena osewera a hardware amawona kokha track 1; WebM imatha pa Opus / Vorbis track.
Kodi ma subtitle amasunga zosunga pamene FLV amasinthidwa kuti MKV?
+
Ma subtitle olimba (ma tracks osankhika) amapulumuka pamene MKV angawagwiritse ntchito: MKV amagwiritsa ntchito SRT, ASS, SSA, PGS, VobSub mwachilengedwe; MP4 amagwiritsa ntchito mov_text (format yosasinthasintha). Kusintha MKV ndi subs a ASS ku MP4 kumawawononga kuti akhale mov_text kapena kuwalemba. Hardsubs (olembana mu kanema) amagwiritsa ntchito ngakhale.
Kodi FLV mpaka MKV amasunga masamba olemba / kuyendera kwa DVD?
+
Chapter metadata transfers between FLV and MKV whenever both containers support a chapter atom (MKV, MP4, MOV). WebM stores chapters in a Matroska-compatible block, so MKV <-> WebM chapters round-trip cleanly. AVI has no chapter spec, so converting AVI to MKV produces an unchaptered file unless you add markers manually.
Kodi ndi chiyani za MKV zowonjezera (fonti, kusindikiza) pamene mukupita FLV ku MKV?
+
MKV ndi yokha mainstream yokhala ndi ma fayilo ophatikizidwa (TTF fonts for ASS subs, JPG cover art, fan-translated PDF inserts). Kuchokera ku FLV kupita ku MKV kumachotsa ma attachments pamene MKV si MKV - ma streams elementary amasinthidwa, koma payload ophatikizidwa amakhala m'malo ochokera. Tengani FLV ngati chitetezo ngati mumatengera ma fonts ophatikizidwa.
Kodi codec yomwe MKV imagwiritsa ntchito ndi yosasinthika?
+
Kodiyi ya default imasankhidwa kuti igwirizane ndi MKV yokhala ndi katundu: MKV imasinthidwa kukhala H.265 (HEVC) kuti ikhale yolimba kwambiri; MP4 imasinthidwa kukhala H.264 kuti ikhale yolimba kwambiri; WebM imasinthidwa kukhala VP9; AVI imagwiritsa ntchito MPEG-4 ASP (DivX / Xvid linage).
Kodi HDR (HDR10, Dolby Vision) imatha bwanji FLV mpaka MKV?
+
HDR static metadata (HDR10 mastering display values, max content light level) imatha kupita ku MKV pamene ma kontena awiri ndi codec osankhidwa amathandizira (HEVC, AV1 mu MKV / MP4). Dolby Vision ndi wolimba kwambiri - DV profile 5 / 7 / 8.1 mu FLV nthawi zambiri amapulumuka okha ku MKV ndi HEVC; kusinthidwa ku MKV kontena lomwe silitha kunyamula gawo la DV limatha ku HDR10.
Kodi wosinthira FLV mpaka MKV adzasunga kusinthasintha kwa framerate (VFR)?
+
MKV ndi WebM amalemba ma timestamps a real-frame ndi kuwongolera VFR mwanjira yachibadwa, kotero kuti FLV VFR imatha kukhala ndi MKV ya mafomuwa popanda kubwezeretsa. MP4 imasunga nthawi yowonjezerapo koma ena osewera amaganiza kuti CFR; wosintha amatulutsa "kulepheretsa CFR" kuti abwezeretse VFR FLV ku 24 / 30 / 60 fps MKV kwa zolinga zosatheka.
Remux ya codec yomweyo imatulutsa kukula kwakukulu (kuphatikiza kwa kontena kumasiyana ndi 0.1-2%). Kusintha kwa codec kungapangitse kukula kwa 50% kapena kuposa: H.264 kupita ku H.265 kumatha kuchepetsa fayilo pazomwe zimawoneka bwino; H.264 kupita ku AV1 kumatha kuchepetsanso panthawi ya slow.Kuchokera ku high-bitrate FLV (Blu-ray rip) kupita ku low-bitrate MKV (kutsitsa pa intaneti) ndichifukwa chofala kwambiri cha kugwa kwakukulu.
Ndiyo mpaka 8K (7680x4320) pa Premium. Mlingo wopanda malire umatha 4K (3840x2160) mpaka kumapeto kwa fayilo ya 1 GB. Ma remuxes oyera (kupita kwa codec yofanana) ya FLV yokulirapo kupita ku MKV amalepheretsa I / O ya diski, osati CPU - 30 GB FLV amasinthanso kupita ku MKV m'miphindi yochepa popanda kuyankhulana. Amasinthanso kukula ndi kuchuluka kwa ma pixel.
Kodi fayilo yanga FLV ndi yapadera panthawi ya MKV yosinthira?

Ndikoyenera - mafayilo a FLV omwe adatulutsidwa amachitidwa m'mawu osiyana ndi omwe amagwira ntchito ndipo amasungidwa m'maola angapo a kumaliza. Sitingawone, kusungira, kusungira kapena kugawana zomwe zili. Onani /privacy/ kwa zenera la kusungira deta. Mzere wosintha umagwira ntchito pazinthu zomwe timawongolera kuyambira pachiyambi mpaka pachiyambi; palibe API yachitatu yomwe imalandira fayilo yanu.
Kodi ndingapeze, kuchotsa, kapena kulumikizana ndi FLV mafayilo panthawi ya MKV yosinthira?

Si pa ntchito yomweyo - onetsetsani kuti kusintha kumakonzekera pa chotengera / codec. Pezani /trim/ kuti muchepetse FLV koyamba, kenako mupange mndandanda wa FLV -> MKV. Kuti mugwirizanitse ma clip angapo m'modzi MKV, chida cha /merge/ chimagwirizana nawo pazomwe zimagwirizana (zimasintha ngati ma input amagawana codec, amasinthanso ngati sichoncho) ndipo amatulutsa fayilo imodzi ya MKV pamapeto pake.
FLV (Kung'anima Video) ndi kanema chidebe mtundu kupanga ndi Adobe. Imagwiritsidwa ntchito posaka mavidiyo pa intaneti ndipo imathandizidwa ndi Adobe Flash Player.
