Wat gebeur wanneer MP4 na MKV omgeskakel word

Bronformaat

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

Teikenformaat

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

Wat verander

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.

Wat behoue bly
Duration, frame order, and visible dimensions are preserved unless you select trimming, frame-rate, or resolution changes.
Wat verlore kan gaan
Extra subtitle, attachment, chapter, or alternate audio tracks may be omitted when the target container or selected settings do not support them.
Gevolge vir kodek en kwaliteit
Container names do not guarantee a codec. Quality and compatibility depend on the selected video codec, audio codec, bitrate, frame rate, and resolution.
Praktiese beperkings
A valid MP4 extension does not guarantee that every codec inside the container is decodable. Corrupt, encrypted, or unusual streams can fail.

Omskakelingstappe

  1. Laai 'n MP4-lêer op wat nie groter as 1 GB is nie.
  2. Bevestig dat MKV as die teiken gekies is.
  3. Open settings only if you need to change codec, quality, bitrate, frame rate, resolution, or audio behavior.
  4. Begin die omskakeling. 'n Gesonde, versoenbare werker begin dit onmiddellik verwerk.
  5. Laai die MKV-lêer af en kontroleer die resultaat voordat jy die bronlêer uitvee.

Probleemoplossing

Die MP4-lêer word afgekeur of wil nie oopmaak nie.
Bevestig dat die lêer nie leeg, wagwoordbeskermd of beskadig is nie, en dat die werklike formaat met die lêeruitbreiding ooreenstem.
Die MKV-lêer is groter as wat verwag is.
Kies, wanneer beskikbaar, 'n doeltreffender kodek of 'n laer kwaliteitinstelling as jy 'n kleiner lêer benodig. Verlieslose en ongekomprimeerde teikenformate is gewoonlik groter.
The result has no sound or will not play.
Try a broadly supported target codec and verify that the source contains a decodable audio stream.

Privaatheid en lêerbewaring

Opgelaaide en omgeskakelde lêers word outomaties verwerk en binne 24 uur onherroeplik uitgevee. Jy kan dit vroeër met die uitveebeheer verwyder. Convertr lees, ontgin, verkoop of beoordeel nie lêerinhoud handmatig nie.
