VOB → MKV

Hapana, uye iyi ndiyo imwe yezvikonzero zviri nani zvekufambisa. VOB mudziyo une yakapusa faira-file ceiling iyo yakareba kana yakakwira-bitrate rekodhi inoenda zvakananga, izvo ndizvo chaizvo nei makamera ekare achisvika sechikamu1, chikamu2, chikamu3. MKV haina muganho wakaenzana, saka mapikicha anogona kudzokera kune imwe file. VOB inonzi yakaparadzwa pakati pemafaera, inogona kunge iri CSS-encrypted, uye inotakura mapakeji ekufamba ayo anokonzera kusagadzikana kwevatambi vezvinangwa zvakasiyana.

Zviri pachena kuti DRM. Zvimwe VOB mafaera anovharwa pabitstream level nekutengesa kana software iyo yakaburitsa iwo, uye yakavharwa mvura haigone kugadziriswa nedu kana nechinhu chero chipi zvacho pasina chiratidzo chelicensing. Mafaira aunenge wanyora, wakatumira kunze kana wakarodha pasi zvisingadzivirirwe zvinoshandura zvakajairika; chibvumirano chekutenga chisiri, uye hapana mushanduri anogona kuvimbisa zvakasiyana.

Zvinogona kunge zvisina. VOB 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. MKV ane anenge hapana native hardware rutsigiro - mafoni, browsers uye TVs zvinoda VLC kana remux pamberi vachava kutamba.

Yese chinhu iwe uchida kuchengeta, yeah. VOB inobva kune yekutanga rudzi rwevideo tooling uye software iyo inoverenga inoramba ichidzoka kubva kumafoni, mabrowser uye maoperating systems. Kufambisa mavhidhiyo ku MKV ikozvino, kunyangwe paine decoder yakachena, ndiyo kusiyana pakati pearchive iwe yaunogona kuvhura mumakore gumi nerimwe uye rimwe iwe hausi. MKV ndiro archiving chigaro chekusarudza nekuti inochengeta unlimited audio matracks, soft subtitles, chapter mapepa uye kuvhura hunyanzvi muimwe faira.

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 VOB 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 VOB kuenda ku MKV kunobvisa izvi zvakaiswa kana MKV hachisi MKV — elementary streams inoshandura, asi zvakaiswa payload zvinogara munzvimbo yekubva. Tenga VOB 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 VOB inogona kutaridzika yakasviba mu MKV.
