M4V pou MKV FAQ sou Konvèsyon
Ki jan mwen ka re-encode M4V nan MKV san yo pa pèdi bon jan kalite videyo?
+
Upload your M4V file and set Quality to High Quality in the conversion options. That re-encodes the video at the highest quality setting (CRF 18 for H.264 and VP9 output), which keeps the most detail at the cost of a larger file. The default, Balanced, uses the standard setting. The MKV output gets a codec its container supports: H.264 for MP4, MOV and MKV, VP9 for WebM. Structurally yon M4V se yon MP4 — H.264 oswa HEVC ak AAC — ak optional Apple FairPlay DRM ak iTunes chapit metadonnées. MKV se codec-agnostic: H.264, HEVC, VP9 ak AV1 videyo sit byen kontan bò kote AAC, FLAC, Opus, DTS oswa Dolby son an nan menm dosye a.
Poukisa dosye M4V mwen an pa ka konvèti nan MKV?
+
DRM. Gen kèk M4V dosye yo enkripte nan nivo bitstream pa magazen an oswa lojisyèl ki te pibliye yo, ak yon flux enkripte pa ka dekode pa nou oswa pa nenpòt lòt bagay san kle lisans lan. Fichiers ou te enskri, ekspòtasyon oswa telechaje pa pwoteje konvèti nòmalman; yon achte lisans pa pral, ak pa gen okenn konvètisè ka honestly pwomèt lòt bagay. DRM-protegé M4V acha pa ka konvèti pa anyen; sèlman M4V fichiers pa pwoteje yo convertibles, ak non-Apple jwè yo souvan bezwen extension rebati.
Èske MKV la pral jwe san pwoblèm sou yon telefòn oswa yon televizyon?
+
Li ka pa. M4V se dekode pa silisyòm dedike sou telefòn, tablèt ak televizyon, ki se poukisa li jwe san yo pa flate batri a. MKV anjeneral retounen nan dekodaj lojisyèl sou menm hardware - chaj CPU ki pi wo, yon aparèy pi cho, ak kadr tonbe sou materyèl 4K. Pou yon aparèy ki vize, M4V se kontenè ki pi an sekirite pou rete nan. MKV gen prèske pa gen okenn natif natal hardware sipò - telefòn, navigatè ak TV bezwen VLC oswa yon remux anvan yo pral jwe li.
M4V ak MKV se tou de kontenè modèn - ki sa ki ta dwe mwen kenbe?
+
Konserve nenpòt ki matche kote dosye a ale, paske pa gen youn ki pi bon nan abstrè. Yon nan de sa yo se bati pou jwe konpatibilite ak lòt la pou kenbe tout sa yon dosye ka genyen, epi yo trade kont youn kont lòt egzakteman sou liy sa a. Reponn pragmatic pou pifò livri se pou archiver nan karakteristik rich- conteneur ak ekspòtasyon nan konpatib la sou demann. M4V kenbe chapit marqueurs, artwork ak sous-titres chante nan fòm Apple TV app espere, ki MP4 plat souvan pèdi. MKV se archives kontenè nan chwa paske li estoke san limit chante, sous-titres mou, chapit marqueurs ak kouch atizay nan yon sèl dosye.
Ki codec videyo MKV ekspòtasyon an itilize?
+
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 se Matroska, yon kontenè louvri ki te fèt an 2002 san okenn restriksyon lisans ak san plafon sou sa li ka kenbe.
Èske travès mwen an pral survive konvèsyon M4V a MKV?
+
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.
Èske mwen ka kenbe framerate orijinal la lè mwen konvèti M4V nan MKV?
+
Yes. The frame rate is kept unless you change it: a 24 fps M4V stays 24 fps in the MKV. The Frame Rate setting can also convert to 60, 30 or 24 fps. It changes the rate only; it does not deinterlace the video or remove 3:2 pulldown.
Ki jan anpil gwosè dosye a pral chanje soti nan M4V a MKV?
+
It depends on what happens to the video. MKV to MP4 or MOV with the default settings copies the video stream unchanged, so the size stays close to the source. Most other pairs re-encode it: a high-bitrate M4V usually comes out smaller, while an already heavily compressed one can grow. Smaller File under Quality gives the smallest output, and H.265 in the Codec setting (MP4, MOV and MKV) is usually smaller than H.264 at similar quality but plays on fewer devices.
Èske MKV dosye a pral jwe sou iPhone, Android, ak Smart TV?
+
MP4 with H.264 plays on practically every phone, browser and TV. MOV with H.264 plays on Apple devices and most TVs but not on every older Android phone. MKV needs an app such as VLC on iOS, and WebM is at home in browsers. There is no device preset on this page, so choose the target format your device supports.
Konbyen tan li pran pou konvèti yon videyo 1 èdtan M4V nan MKV?
+
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.
Ki sa ki se rezoud maksimòm sipòte pou M4V a MKV?
+
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 colour, so an HDR M4V can look washed out.
Èske M4V videyo mwen an prive pandan konvèsyon an nan MKV?
+
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.
