MKV chun MP4 Ceisteanna Coitianta maidir le Comhshó
Conas a thiontú mé MKV go MP4 gan an sruth físe a athchódú?
+
There is no stream-copy switch on this page. A few pairs copy a compatible video stream into the MP4 container without re-encoding it, MKV to MP4 among them, which is quick and loses no quality. Most pairs re-encode the video. Is MKV codec-agnostic: H.264, HEVC, VP9 agus AV1 físeán suí sona sásta in aice le AAC, FLAC, Opus, DTS nó Dolby fuaime sa chomhad céanna. Is beagnach gach MP4 san fhiáine físeán H.264 le fuaim AAC; tá an coimeádán freisin go dlíthiúil HEVC, AV1 agus VP9.
An mbeidh an MP4 ag imirt i mbrabhsálaí nuair nach mbeadh an MKV?
+
Sea, agus is é sin an chúis iomlán leis an gcomhshó de ghnáth. Taispeánann MKV leabaithe i leathanach gréasáin imreoir briste nó fórsaí íoslódáil, toisc nach bhfuil aon díchódóir ann do bhrabhsálaithe. MP4 imríonn sé inlíne tríd an ngné físe HTML5 dúchais gan aon bhreiseán agus gan aon iarratas seachtrach. Is MP4 an sprioc seachadta is sábháilte is féidir - gach fón, brabhsálaí, console, eagarthóir agus Smart TV tógtha sna deich mbliana anuas imríonn sé gan bogearraí breise.
Is coimeádáin nua-aimseartha iad MKV agus MP4 araon - cé acu ba chóir dom a choinneáil i ndáiríre?
+
Coinnigh an ceann is fearr leat, mar níl aon cheann níos fearr ná an ceann eile. Tá ceann acu seo tógtha le haghaidh comhoiriúnachta athsheinm agus an ceann eile le haghaidh gach rud a d' fhéadfadh a bheith i gcomhad, agus déanann siad trádáil lena chéile díreach ar an líne sin. Is é an freagra praiticiúil don chuid is mó de na leabharlanna cartlann a dhéanamh sa choimeádán saibhir gnéithe agus é a easpórtáil go dtí an ceann comhoiriúnach ar éileamh. Is MKV an coimeádán cartlainne de rogha toisc go stórálann sé rianta fuaime unlimited, fotheidil bog, marcóirí chaibidil agus ealaín chlúdach i gcomhad amháin.
An mairfidh fuaim ilrian MKV go MP4 comhshó?
+
Usually not. Most conversions keep one audio track, the one with the most channels (normally the main mix), re-encoded for the MP4 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 MKV with that track first (VLC or ffmpeg can do this), then convert it. Is MP4 ISO / IEC 14496-14, caighdeánaithe i 2001 agus a dhíorthaítear ó na húsáidí bosca leagan amach QuickTime céanna MOV.
An gcoimeádtar rianta fotheidil nuair a dhéantar MKV a thiontú go MP4?
+
On some pairs. MP4 to MOV keeps every text subtitle track. AVI, WMV, MPEG, FLV, VOB and M4V to MKV keep every subtitle track: text subtitles 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.
Cad é faoi iatáin MKV (clónna, ealaín chlúdaigh) nuair a théann MKV go MP4?
+
Is é MKV an t- aon choimeádán príomhshrutha a stórálann comhaid ghabhálacha treallach (clónna TTF le haghaidh fotheidil ASS, ealaín chlúdaigh JPG, ionchuir PDF aistrithe ag lucht leanúna). Ag dul ó MKV go MP4 scaoilfear na iatán seo nuair nach MKV é MP4 - déanann na sruthanna bunúsacha a thiontú, ach fanann an pálucht ceangailte sa fhoinse. Coinnigh MKV mar chúltaca má tá tú ag brath ar chlónna ceangailte.
Cén codán a úsáideann an t-aschur MP4 de réir réamhshocraithe?
+
It depends on the MP4 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. Tacaíonn MP4 ach amháin go forleathan-onóir fotheideal formáid (mov_text), agus tá fuaime il-rian neamhiontaofa taobh amuigh imreoirí deisce.
Conas a mhaireann HDR (HDR10, Dolby Vision) MKV go MP4?
+
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 as it is. When the video is re-encoded, the HDR10 mastering metadata is dropped and Dolby Vision or HDR10+ data is not kept, and with a Quality, Resolution or Frame Rate setting some pairs also reduce the video to 8-bit colour, so an HDR MKV can look washed out in the MP4.
Cén fáth go bhfuil mo MP4 comhad níos lú / níos mó ná an MKV tar éis comhshó?
+
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 MKV 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.
An láimhseálann an tiontaire MKV go MP4 ábhar 4K / 8K / 60fps?
+
The converter has no resolution cap of its own; the limit is the upload size allowed on your plan, and 4K, 8K and 60 fps files keep their resolution and frame rate unless you change them. MKV to MP4 or MOV with the default settings copies the video stream, which is quick at any resolution. Other pairs re-encode on CPU and the time grows with the pixel count, so a long 4K or 8K file takes much longer than the same length in 1080p.
