MOV → HLS

A MOV yakaiswa muwebhu peji inoratidzwa neakavharwa mutambi kana kumanikidza kurodha pasi, nekuti mabrowser haasi kutumira chero decoder. HLS anotamba munzira kuburikidza neiyo yakasarudzika HTML5 video element pasina plugin uye pasina kunze kweapplication. HLS inoshandura kune muverengi webandwidth munguva chaiyo uye ndiyo chete streaming format Safari uye iOS inotsigira zvakananga.

Ichi chinochinja zvatingatarisira kubva ku output file. Imwe pfungwa yechikonzero ichi ndechekuti, kana tichichinja, tichashandisa encoding sezviri nyore kupfuura wrapper, saka zvatichawana ndezvekuti, kana tichichinja, tichashandisa iyo bitstream mukati mechikonzero chinotibatsira—semuenzaniso, MP4 kana MKV. Kuwedzera kunotaura nezvechikonzero; codec ndiyo inosarudza saizi yechikonzero uye kuti ichatamba sei.

Usually not. Most conversions keep one audio track, the one with the most channels (normally the main mix), re-encoded for the HLS 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 MOV with that track first (VLC or ffmpeg can do this), then convert it. HLS ndeye Apple HTTP Live Streaming - kwete faira asi playlist pamwe nefolda yezvidimbu zvenhau.

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 MOV kuenda ku HLS kunobvisa izvi zvakaiswa kana HLS hachisi MKV — elementary streams inoshandura, asi zvakaiswa payload zvinogara munzvimbo yekubva. Tenga MOV se backup kana iwe uchida kuvimba nezvinyorwa zvakaiswa.

Izvi zvinoenderana ne HLS 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. HLS hachisi chimwe chete chinorodha faira - kuti ugare uchivhara, iwe unofanirwa kudzokera kunzvimbo yechinyakare chitoro chekutanga.

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 MOV inogona kutaridzika yakasviba mu HLS.

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 MOV 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.

The converter haina rusununguko cap yacho; mutemo ndewekutumira kureba kubvumirwa pachirongwa chako, uye 4K, 8K uye 60 fps mafaera kuchengetedza rusununguko hwavo uye frame rate kana iwe kuchinja kwavo. MKV kuti MP4 kana MOV nedefault settings inonyora video stream, iyo yakati wandei pa chero resolution. Other vaviri re-encode pa CPU uye nguva inokura ne pixel kuongorora, saka a 4K kana 8K file anenge atora nguva yakareba kupfuura iyo imwecheteyo nguva mu 1080p.
