MP4 ze maachen MKV Konversiouns-FAQ

Wéi kann ech MP4 op MKV ëmkoden ouni d'Videoqualitéit ze verléieren?
+
Upload your MP4 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. D'Grupp vun de 4000 Stären, déi am Stärebild Virgo läit, ass eng Grupp vu ronn 1000 Stären, déi an der Spektralklass A1, A2, A3 an A4 falen. D'Videoen, déi am MKV-Format gespillt ginn, sinn an de Formater H.264, HEVC, VP9, AV1, AAC, FLAC, Opus, DTS, Dolby Audio an AVCHD.
Net direkt. MP4 gëtt an all Browser inline gespillt; MKV net, also kënnt eng Säit mat engem Downloadlink oder engem leeren Playerframe. Wann d' Datei fir eng Websäit geduecht ass, da behalen MP4 fir d'Websäit an behandelen MKV als Archiv oder Beaarbechtungskopie. D'Spill ass net op d'mannst op engem Computer, Tablet oder Smartphone ze spillen, mee op engem Computer oder Smartphone.
Et kann net sinn. MP4 gëtt op Handyen, Tabletten a Fernseher mat engem speziellen Silizium decodéiert, dat ass firwat et gespillt gëtt ouni d'Batterie ze iwwerlasten. MKV geet normalerweis op Software-Decodéierung op der selwechter Hardware zréck - méi héich CPU-Belaaschtung, e méi waarmt Apparat, a gefall Frames op 4K Material. Fir en Apparat Zil ass MP4 de séchersten Container fir ze bleiwen.
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. D'Majoritéit vun de Membere vun der Gemeng huet 2002 no enger neier Verfassung, déi net méi ännere kann, de Sëtz verluer.
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. D'Archiv ass eng vun de wichtegsten Archiven an der Geschicht vun der Lëtzebuerger Literatur, mat enger ganzer Rei vun Dokumenter, déi an der Bibliothéik gelagert sinn.
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.
Yes. Uploaded MP4 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.
Not in the same step. Use /trim-video/ or /video-cutter/ to clip the MP4 first, or /rotate-video/ to turn it, then run the MP4 to MKV conversion. Trimming first is faster than re-encoding the whole MP4 just to drop unused footage.
