Kaj se zgodi, ko MP4 postane MKV

Izvorni format

MP4 is a widely supported media container, commonly carrying H.264 or H.265 video and AAC audio.

Ciljni format

MKV is a flexible Matroska container that can carry multiple audio, video, and subtitle tracks.

Kaj se spremeni

The MP4 container is read and the selected video and audio streams are written into a MKV container.

Codecs may be transcoded even when the visible resolution and duration stay the same.

Kaj se ohrani
Duration, frame order, and visible dimensions are preserved unless you select trimming, frame-rate, or resolution changes.
Kaj se lahko izgubi
Extra subtitle, attachment, chapter, or alternate audio tracks may be omitted when the target container or selected settings do not support them.
Vpliv kodeka in kakovosti
Container names do not guarantee a codec. Quality and compatibility depend on the selected video codec, audio codec, bitrate, frame rate, and resolution.
Praktične omejitve
A valid MP4 extension does not guarantee that every codec inside the container is decodable. Corrupt, encrypted, or unusual streams can fail.

Koraki pretvorbe

  1. Naložite datoteko MP4, ki ni večja od 1 GB.
  2. Prepričajte se, da je kot ciljni format izbran MKV.
  3. Open settings only if you need to change codec, quality, bitrate, frame rate, resolution, or audio behavior.
  4. Začnite pretvorbo. Zdrav in združljiv strežnik začne obdelavo takoj.
  5. Prenesite datoteko MKV in preverite rezultat, preden izbrišete izvorno datoteko.

Odpravljanje težav

Datoteka MP4 je zavrnjena ali se ne odpre.
Prepričajte se, da datoteka ni prazna, zaščitena z geslom ali poškodovana ter da njena dejanska oblika ustreza končnici.
Datoteka MKV je večja od pričakovane.
Če je mogoče, izberite učinkovitejši kodek ali nižjo nastavitev kakovosti. Formati brez izgub in nestisnjeni formati so po zasnovi pogosto večji.
Rezultat nima zvoka ali ga ni mogoče predvajati.
Poskusite široko podprt ciljni kodek in preverite, ali vir vsebuje zvočni tok, ki ga je mogoče dekodirati.

Zasebnost in hramba datotek

Naložene in pretvorjene datoteke se obdelajo samodejno in se v 24 urah nepovratno izbrišejo. Z možnostjo brisanja jih lahko izbrišete prej. Convertr vsebine datotek ne bere, analizira, prodaja ali ročno pregleduje.
