MP4 ka MKV FAQ Konversi

There is no stream-copy switch on this page. A few pairs copy a compatible video stream into the MKV container without re-encoding it, MKV to MP4 among them, which is quick and loses no quality. Most pairs re-encode the video. Sacara umum, MP4 dipaké pikeun nyimpen video H.264, audio AAC, sarta kodekan audio HEVC, AV1, VP9, sareng VP9. MKV ora nganggo kodeke: H.264, HEVC, VP9, AV1 video bisa diunggah bareng karo AAC, FLAC, Opus, DTS, Dolby Audio, lan liya-liyane.

Apa audio multi-track bakal tetep ana nalika ngowahi MP4 dadi MKV?
+
Usually not. Most conversions keep one audio track, the one with the most channels (normally the main mix), re-encoded for the MKV container, so commentary and alternate-language tracks are dropped. AVI, WMV, MPEG, FLV, VOB and M4V to MKV keep every track, and so does MP4 to MOV. To keep a different track, remux the MP4 with that track first (VLC or ffmpeg can do this), then convert it. MKV nyaéta Matroska, hiji kontener terbuka anu dirancang dina taun 2002 tanpa watesan lisénsi sareng tanpa watesan kana naon anu tiasa disimpen.
Apa trek subtitle bakal disimpen nalika ngowahi MP4 dadi MKV?
+
On some pairs. MP4 to MOV keeps every text subtitle track. AVI, WMV, MPEG, FLV, VOB and M4V to MKV keep every subtitle track: text subtitles are copied or converted to SRT, and picture-based subtitles such as DVD or Blu-ray ones are copied as they are. MP4, MOV and WebM to MKV keep only the first subtitle track (as ASS), and MP4 to WebM keeps the first one as WebVTT. Other pairs, including MKV to MP4 or MOV and WebM to MP4, drop subtitle tracks, and the converter does not burn them into the picture. Subtitles that are already burned in stay, because they are part of the video frames.

Codec apa sing digunakake output MKV kanthi piawai?
+
It depends on the MKV container. MP4, MOV and MKV output use H.264, which plays on practically every phone, browser and TV. WebM output uses VP9. AVI, WMV and MPEG output use the older codecs those formats were designed for.
Apa sing diarani HDR (HDR10, Dolby Vision) bisa urip MP4 nganti MKV?
+
There is no HDR processing or tone mapping. When the video stream is copied (MKV to MP4 or MOV with the default settings), HDR10 passes through as it is. When the video is re-encoded, the HDR10 mastering metadata is dropped and Dolby Vision or HDR10+ data is not kept, and with a Quality, Resolution or Frame Rate setting some pairs also reduce the video to 8-bit colour, so an HDR MP4 can look washed out in the MKV.
Mengapa file MKV saya lebih kecil / lebih besar daripada MP4 setelah konversi?
+
It depends on what happens to the video. MKV to MP4 or MOV with the default settings copies the video stream unchanged, so the size stays close to the source. Most other pairs re-encode it: a high-bitrate MP4 usually comes out smaller, while an already heavily compressed one can grow. Smaller File under Quality gives the smallest output, and H.265 in the Codec setting (MP4, MOV and MKV) is usually smaller than H.264 at similar quality but plays on fewer devices.
