FLV → MKV

Yeah. FLV haina kushandiswa kweiyo soft-subtitle track, saka subtitle ye FLV zvikamu zvaifanira kusvibiswa mufananidzo kana kuendeswa seyakazvimiririra sidecar faira. MKV inotakura subtitle sezvavanosarudza, saka mushure mekushandurwa unogona kubatanidza SRT track iyo muverengi anogona kuvhura, kudzima kana kushandura.

Yeah, uye ndiyo yakasarudzika kuvandudzwa pane FLV. MKV inobata chero audio stream seyekutanga-mhando track, saka mutsara wekutanga wechirungu, dub uye director's commentary anogona kugara muimwe faira nemutambi achichinja pakati pavo pavanoda. MKV ndiro archiving chigaro chekusarudza nekuti inochengeta unlimited audio matracks, soft subtitles, chapter mapepa uye kuvhura hunyanzvi muimwe faira.

Yese chinhu iwe uchida kuchengeta, yeah. FLV 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. Hapana browser, foni kana TV inogona kutamba FLV — chero chinhu chiri mubhokisi iri chinofanira kuendeswa kunze kuti chirambe chichionekwa.

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 FLV 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 FLV kuenda ku MKV kunobvisa izvi zvakaiswa kana MKV hachisi MKV — elementary streams inoshandura, asi zvakaiswa payload zvinogara munzvimbo yekubva. Tenga FLV 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. MKV ane anenge hapana native hardware rutsigiro - mafoni, browsers uye TVs zvinoda VLC kana remux pamberi vachava kutamba.

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 FLV inogona kutaridzika yakasviba mu MKV.

Izvi zvinoenderana nezvakaitika kuvhidhiyo. MKV kuti MP4 kana MOV ne default settings makopi video stream pasina kuchinja, saka kureba inogara pedyo nenzvimbo. Akawanda vamwe vaviri re-encode it: a high-bitrate FLV zvinonyanya kuuya kunze makuru, apo achiri zvikuru zvakakomberedza imwe anogona kukura. Smaller File pasi Quality inopa makuru kubuda, uye H.265 mu Codec setting (MP4, MOV uye MKV) zvinonyanya makuru kupfuura H.264 pa zvakafanana kunaka asi anotamba pa zvishoma zvinoshandiswa.
