Plan MKV to MP4 conversion without confusing container changes with codec changes. The page explains when remuxing works and when subtitles, audio, or codecs require a different path.
MKV can contain many video, audio, subtitle, and attachment tracks. A safe MP4 plan should choose the tracks that MP4 and the target device actually support.
A useful MKV to MP4 page should warn users that not every MKV track belongs in MP4. It should make track selection, subtitle handling, and compatibility visible.
Video, audio, subtitles, and chapters are not the same decision.
The page explains why some MKV files need re-encoding.
Complex jobs go to FFmpeg Generator, not a vague one-click button.
The page should guide users to a valid MP4 result rather than a broken file with unsupported tracks.
| Situation | Best route | Why |
|---|---|---|
| H.264 video + AAC audio | Remux to MP4 | The common fast path. |
| ASS/SSA subtitles | Burn or external | MP4 support is limited for rich subtitles. |
| Multiple audio tracks | Select track | Avoid confusing output for normal users. |
| Unsupported codecs | Re-encode | Container change alone will not fix playback. |

MKV is flexible; MP4 is broadly compatible. The right choice depends on target playback.
Some subtitle formats do not transfer cleanly to MP4. External or burned subtitles may be better.
The codecs or tracks may not be compatible with MP4 or the target player.
