MP4 → MKV

Heoi, he whakawhānui tūturu i runga i te MP4. MKV e whakaaro ana ki ia rerenga oro hei rererangi ā-ira tuatahi, kia noho ai te whāranu reo taketake, te tāruatanga me te kōrero a te kaiwhakahaere i tētahi pūranga kotahi me te kaipāpāho e whakawhiti ana i waenganui i a rātau i te tono. Ko MKV te pūranga kōwhiringa o te kōwhiringa nā te mea ka pupuri i ngā aho whakatere, ngā whakahua whakahua, ngā tohu wāhanga me ngā toi kāwai i roto i tētahi pūranga kotahi.

Kāore i te hāngai. MP4 e whakatangitangi ana i roto i ia kaitiaki; MKV kāore, nā reira ka uru mai tētahi pou e whakatū ana ki tētahi pātahitanga whakahua, ki tētahi tākaro rānei. Mēnā kua whakaritea te faila mō tētahi wāhi, ka pupuri i te MP4 mō te Wīwī, ā, ka whakaarotia te MKV hei pūranga, hei tārua whakarākei rānei. Tata tonu ki te kore e tautokona e MKV ngā pūrere māori — ko ngā pūrongo, ngā kaituhi me ngā pouaka whakaata e hiahiatia ana e VLC, he remux rānei i mua i te whakataetae.

Tērā pea kāore. MP4 e whakakōrerotia ana e te pūkoro whakatapua i runga i ngā pūkoro, ngā tāpapa me ngā TV, nā reira ka tākaro i te pūrere me te kore whakawātea i te pūkoro. MKV i te nuinga o te wā ka hoki ki te whakakōrero pūmanawa i runga i te pūrere ōrite — te utu CPU tiketike ake, he pūrere wera, me ngā tāruatanga i runga i ngā rauemi 4K. Mō tētahi whāinga pūrere, MP4 ko te pūrere haumaru ake hei noho i roto.

E pupuri ana i ngā ōritetanga i reira ka haere te faila, nā te mea kāore e pai ake i te whakarārangi. Ko tētahi o ēnei e rua e hangaia ana mō te ōritetanga whakatere, ā, ko tētahi atu mō te pupuri i ngā mea katoa ka taea e tētahi pūranga te pupuri, ā, ka whakawhitiwhiti rātou ki a rātou anō i runga i taua raina. Ko te whakautu ā-pūnaha mō te nuinga o ngā puna ko te pūranga i roto i te pūrere āhuahira-tōtika me te whakawātea ki te ōrite i te tono. Ko MP4 te ūnga whakawhiwhinga tino haumaru rawa - ko ia whatunga, kaitiaki, pāpāho, kaiwhakawhanake me te Smart TV i hangaia i roto i te tekau tau i muri mai e whakawhiwhia ana ki te kore pūmanawa tāpiri.

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. Ko MKV ko Matroska, he pūrere tūwhera i hangaia i te tau 2002 me te kore whakawhanake ā-whakahaere, ā, kāore he taumata ki te mea ka taea e ia te pupuri.

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.

Yes. The frame rate is kept unless you change it: a 24 fps MP4 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.

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 MP4 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.

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.

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 colour, so an HDR MP4 can look washed out.
