Nola birkodetu MKV MP4(e)ra bideo-kalitatea galdu gabe?
+
Upload your MKV 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 MP4 output gets a codec its container supports: H.264 for MP4, MOV and MKV, VP9 for WebM. MKV kodeke-agnostikoa da: H.264, HEVC, VP9 eta AV1 bideoak AAC, FLAC, Opus, DTS edo Dolby audioaren ondoan daude fitxategi berean. MP4 formatu gehienak H.264 bideoa AAC audioarekin, eta HEVC, AV1 eta VP9 ere legez onartzen ditu.
MP4 arakatzaile batean erreproduzituko da MKV ez bada erreproduzitzen?
+
Bai, eta hori da bihurketaren arrazoi nagusia. Web-orri batean txertatutako MKV-k erreproduzitzaile hautsi bat erakusten du edo deskargatzea behartzen du, arakatzaileek ez dutelako horretarako deskodetzailerik bidaltzen. MP4 HTML5 bideo-elementu natiboaren bidez erreproduzitzen da, pluginik eta kanpoko aplikaziorik gabe. MP4a ahalik eta entregatze helburu seguruena da, azken hamarkadan eraikitako telefono, nabigatzaile, kontsola, editore eta Smart TV guztiek software gehigarririk gabe erreproduzitzen dute.
Bi MKV eta MP4 edukiontzi modernoak dira - zein mantendu behar dut?
+
Mantendu fitxategia nora doan adierazten duen bat datorrena, ez dagoela hoberik abstrakzioan. Bi hauetako bat erreprodukziorako bateragarritasunerako eraiki da eta bestea fitxategi batek eduki dezakeen guztia gordetzeko, eta elkarren aurka negoziatzen dute zuzenean lerro horretan. Liburutegi gehienen erantzun pragmatikoa funtzio-osagarridun edukiontzian artxibatzea da, eta eskaera egin ondoren bateragarrira esportatzea. MKV aukeratutako artxibo edukiontzia da, audio pista mugagabeak, azpititulu bigun, kapitulu markatzaileak eta azalaren artea fitxategi batean gordetzen dituelako.
Zein bideo-kodeke erabiltzen du MP4 irteerak?
+
It depends on the MP4 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. MP4 ISO/IEC 14496-14 estandarraren arabera definitutako bideo formatua da, 2001ean estandarizatua eta QuickTimeren MOV formatuarekin bateragarria.
Nire audio-pistak iraungo du MKV-tik MP4-ra bihurtzean?
+
Yes, the main audio track comes through, re-encoded to a codec the MP4 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.
Mantendu al dezaket jatorrizko fotograma-emaria MKV MP4 bihurtzean?
+
Yes. The frame rate is kept unless you change it: a 24 fps MKV stays 24 fps in the MP4. 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.
Zenbat aldatuko da fitxategiaren tamaina MKV(e)tik MP4(e)ra?
+
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 MKV 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 fitxategia iPhone, Android eta Smart TVetan erreproduzituko da?
+
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. MP4k azpitituluen formatu bat bakarrik onartzen du (mov_text), eta pista anitzeko audioa ez da fidagarria mahaigaineko erreproduzitzaileetatik kanpo.
Zenbat denbora behar da ordubeteko MKV bideo bat MP4 bihurtzeko?
+
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.
Zein da MKV eta MP4 artean onartutako gehienezko bereizmena?
+
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 MKV can look washed out.
Nire MKV bideoa pribatua da MP4 bihurtzean?
+
Yes. Uploaded MKV files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted MP4 are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
Ebaki, moztu edo biratu dezaket MKV-(e)tik MP4-(e)ra bihurtzean?
+
Not in the same step. Use /trim-video/ or /video-cutter/ to clip the MKV first, or /rotate-video/ to turn it, then run the MKV to MP4 conversion. Trimming first is faster than re-encoding the whole MKV just to drop unused footage.
