MKV ndiro archiving chigaro chekusarudza nekuti inochengeta unlimited audio matracks, soft subtitles, chapter mapepa uye kuvhura hunyanzvi muimwe faira.

Hapana zvakananga. MP4 inotamba mumisoro muchero wese webrowser; MKV haina, saka peji richiisa rinova kurodha pasi kubatanidza kana kutamba mutsara wakasununguka. Kana faira iri kutarisirwa kune webhusaiti, chengetedza MP4 yewebhu uye tarisa MKV sechinyorwa kana kuchinja kopi. MKV ane anenge hapana native hardware rutsigiro - mafoni, browsers uye TVs zvinoda VLC kana remux pamberi vachava kutamba.

Zvinogona kunge zvisina. MP4 inodzokororwa neyakazvimirira silicon pafoni, matablets uye TVs, izvo zvinoita kuti iite pasina kusvibisa bhatiri. MKV zvinonyanya kudzokera kusoftware decoding pane iyo imwechete hardware - yakakwira CPU kumanikidza, yakakwira-yakakwira chigadzirwa, uye yakaderera-yakaderera maframes pa4K zvinhu.

Kuchengeta chero mazita anofananidza uko faira iri kuenda, nekuti hapana chinhu chinonakidza. Mumwe wezviviri izvi zvakagadzirwa kuti zvifananidze kutamba uye chimwe chezviviri izvi chinonakidza kuti chitore zvese izvo faira inogona kusanganisira, uye ivo vanotengesa mumwe nemumwe zvakananga pamusoro pechiso. Iyo pragmatic mhinduro yemabhuku akawanda ndeyekuchengeta mubhokisi rakapfuma muzvimiro uye kutumira kune imwe inowirirana pazvinoda. MP4 ndiyo yakachengeteka kwazvo yekutumira chinangwa - chero foni, browser, console, munyori uye Smart TV yakagadzirwa mumakore apfuura inotamba pasina software.

Usually not. Most conversions keep one audio track, the one with the most channels (normally the main mix), re-encoded for the MKV container, so commentary and alternate-language tracks are dropped. AVI, WMV, MPEG, FLV, VOB and M4V to MKV keep every track, and so does MP4 to MOV. To keep a different track, remux the MP4 with that track first (VLC or ffmpeg can do this), then convert it. MKV ndiyo Matroska, yakavhurika chigaro chakagadzirwa muna 2002 pasina kubvumidzwa kwekurambidzwa uye pasina chigaro pane zvaigona kuchengeta.

On some pairs. MP4 kuti MOV anoita kuti zvose subtitle track. AVI, WMV, MPEG, FLV, VOB uye M4V kuti MKV anoita kuti zvose subtitle track: subtitle texts are copied or converted to SRT, and picture-based subtitles such as DVD or Blu-ray ones are copied as they are. MP4, MOV and WebM to MKV keep only the first subtitle track (as ASS), and MP4 to WebM keeps the first one as WebVTT. Other pairs, including MKV to MP4 or MOV and WebM to MP4, drop subtitle tracks, and the converter does not burn them into the picture. Subtitles that are already burned in stay, because they are part of the video frames.

MKV ndiyo chete mainstream container iyo inochengeta zvakananga zvakaiswa mafaera (TTF fonts ye ASS subs, JPG cover art, fan-translated PDF inserts). Kubva ku MP4 kuenda ku MKV kunobvisa izvi zvakaiswa kana MKV hachisi MKV — elementary streams inoshandura, asi zvakaiswa payload zvinogara munzvimbo yekubva. Tenga MP4 se backup kana iwe uchida kuvimba nezvinyorwa zvakaiswa.

Izvi zvinoenderana ne MKV chigaro. MP4, MOV uye MKV kubuda kushandisa H.264, iyo inotamba pachokwadi pamwechete chero foni, browser uye TV. WebM kubuda kushandisa VP9. AVI, WMV uye MPEG kubuda kushandisa vadiki codecs avo mafomati vakagadzirwa.

Hapana HDR kuongorora kana tone mapping. Kana video stream yakakomberedzwa (MKV ku MP4 kana MOV ne default settings), HDR10 inoenda kuburikidza sezvairi. Kana video ichidzokororwa, HDR10 mastering metadata inodzokororwa uye Dolby Vision kana HDR10 + data haisi kuchengetwa, uye neQuality, Resolution kana Frame Rate setting mamwe maperembudzi anoderedzawo video kune 8-bit color, saka HDR MP4 inogona kutaridzika yakasviba mu MKV.
