What happens when MKV becomes AAC
ターゲットフォーマット
AAC is a lossy audio codec that is efficient at moderate bitrates.
どんな変化
The audio stream is decoded from the MKV container and encoded as AAC audio.
The video track, frames, subtitles, chapters, and visual metadata are not included in the audio output.
- 何が保持されるか
- Audio duration and channel layout are preserved when the source stream and target codec support them.
- What may be lost
- All visual content is intentionally discarded.
- Codec and quality implications
- AAC uses lossy compression. A higher quality or bitrate can reduce new artifacts, but it cannot restore detail already missing from the MKV source.
- Realistic limitations
- A MKV file with no decodable audio stream cannot produce AAC audio. Corrupt, encrypted, or unsupported codecs can also fail.
変換ステップ
- Upload a MKV file no larger than 1 GB.
- Confirm that AAC is selected as the target.
- Start the conversion. A healthy compatible worker begins processing immediately.
- Download the AAC file and check the result before deleting your source.
トラブル解決
- The MKV 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 AAC 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.
プライバシーとファイル保管
