Wasu M4V fayiloli ana rufe su a mataki na bitstream ta wurin shagon ko manhajar da ta fitar da su, kuma ba za a iya rufe wani mataki da aka rufe ba ta hanyarmu ko kuma wani abu ba tare da maɓallin lasisi.

Zai iya ba. M4V ana decode da silicon mai dacewa a kan wayoyin hannu, kwamfutoci da TV, wanda shi ne dalilin da ya sa yake wasa ba tare da ya yi wa batirin damuwa ba. MKV na da yawa yana komawa ga decode na kayan aikin a kan irin wannan kayan aiki — mafi girman nauyi na CPU, mai zafi na'ura, da kuma rarraba firam a kan abun 4K. Ga wani manufa na'ura, M4V shi ne mafi aminci na'ura da za'a zauna cikinta. MKV yana da kusan babu goyon baya na asali na kayan aiki - wayoyin hannu, shafuka da TVs suna buƙatar VLC ko remux kafin su yi wasa da shi.

@ action M4V na riƙe da alamun shafi, zane da shirye-shiryen ƙarya a cikin siffar da shirin ayuka na Apple TV ke tsammani, wanda MP4 na ɗabi'a ke rasa da yawa. MKV shi ne mai riƙe da arshi na zaɓi saboda yana adana waƙoƙin sauti ba tare da iyaka ba, sassaƙan rubutu, maɓallan sashe da zane-zane na kwafin cikin fayil guda.

It depends on the MKV container. MP4, MOV and MKV output use H.264, which plays on practically every phone, browser and TV. WebM output uses VP9. AVI, WMV and MPEG output use the older codecs those formats were designed for. MKV shi ne Matroska, wani ƙuƙumi mai buɗewa wanda aka tsara a cikin 2002 da babu ƙuncin lasisi da babu tsawo kan abin da zai iya riƙe.

Yes, the main audio track comes through, re-encoded to a codec the MKV container plays, for example AAC in MP4 and MOV or Opus in WebM. Most conversions keep only that one track (the one with the most channels), so alternate languages and commentary are dropped. MP4 to MOV, and AVI, WMV, MPEG, FLV, VOB or M4V to MKV, keep every audio track.

Yanzu. An riƙe adadin firam sai kun canza shi: 24 fps M4V yana da 24 fps a cikin MKV. Shirin adadin firam na iya canzawa zuwa 60, 30 ko 24 fps. Yana canja adadin kawai; ba zai cire haɗin bidiyo ba ko kuma cire 3:2 pulldown.

Wannan yana dogara da abin da ke faruwa ga bidiyo. MKV zuwa MP4 ko MOV tare da daidaitattun diff yana kwafewa bidiyo stream ba tare da canji ba, don haka girman yana da nisa zuwa wurin asali. Mafi yawan sauran ma'aurata suna sake encode shi: high-bitrate M4V yana da kyau ya fita mafi ƙaranci, yayin da wani wanda ya riga ya yi nauyi ya iya girma. Fitar da Fayil Mai Kauri a ƙarƙashin Tsarin Yana ba da mafi ƙarancin fitarwa, kuma H.265 a cikin daidaitattun Codec (MP4, MOV da MKV) yana da kyau mafi ƙaranci fiye da H.264 a matsayin inganci mai kama da shi amma yana wasa a kan na'urori kaɗan.

MP4 tare da H.264 wasa a kan kusan kowace wayar, mai bincike da TV. MOV tare da H.264 wasa a kan Apple na'urorin da mafi TV amma ba a kan kowace mafi girma Android waya. MKV bukatar wani app kamar VLC a kan iOS, da WebM ne a gida a cikin masu bincike. Babu wani na'urar preset a kan wannan shafi, don haka zaɓi da format na manufa na'urar ka goyon baya.

There is no fixed time: it depends on the length, the resolution and the target format. Conversions run on our servers' CPUs with software encoders; there is no GPU acceleration. MKV to MP4 or MOV with the default settings copies the video stream and is the quickest. A re-encode to H.264 takes longer, and WebM (VP9) is the slowest target, several times slower than H.264 in our tests.

The converter has no resolution cap of its own; the limit is the upload size allowed on your plan, and the resolution stays as it is unless you choose 1080p, 720p or 480p. There is no HDR processing or tone mapping. When the video stream is copied (MKV to MP4 or MOV with the default settings), HDR10 passes through untouched. A re-encode drops the HDR10 mastering metadata, and with a Quality, Resolution or Frame Rate setting some pairs also reduce the video to 8-bit color, so a HDR M4V can look washed out.

Yes. Uploaded M4V files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted MKV are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
