What happens when M4V becomes MKV
Formaty docelowe
MKV is a flexible Matroska container that can carry multiple audio, video, and subtitle tracks.
Jakie zmiany
The M4V 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.
- Co jest zachowywane
- Duration, frame order, and visible dimensions are preserved unless you select trimming, frame-rate, or resolution changes.
- What may be lost
- Extra subtitle, attachment, chapter, or alternate audio tracks may be omitted when the target container or selected settings do not support them.
- Codec and quality implications
- Container names do not guarantee a codec. Quality and compatibility depend on the selected video codec, audio codec, bitrate, frame rate, and resolution.
- Realistic limitations
- A valid M4V extension does not guarantee that every codec inside the container is decodable. Corrupt, encrypted, or unusual streams can fail.
Krok konwersji
- Upload a M4V file no larger than 1 GB.
- Confirm that MKV is selected as the target.
- Open settings only if you need to change codec, quality, bitrate, frame rate, resolution, or audio behavior.
- Start the conversion. A healthy compatible worker begins processing immediately.
- Download the MKV file and check the result before deleting your source.
rozwiązywanie problemów
- The M4V file is rejected or will not open.
- Confirm that the file is not empty, password-protected, or corrupt and that its real format matches the extension.
- The MKV file is larger than expected.
- Choose a more efficient codec or lower quality setting when available. Lossless and uncompressed targets are often larger by design.
- 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.
