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 FLV with that track first (VLC or ffmpeg can do this), then convert it. MKV shi ne Matroska, wani ƙuƙumi mai buɗewa wanda aka tsara a cikin 2002 da babu ƙuncin lasisi da babu tsawo kan abin da zai iya riƙe.

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. MKV yana da kusan babu goyon baya na asali na kayan aiki - wayoyin hannu, shafuka da TVs suna buƙatar VLC ko remux kafin su yi wasa da shi.

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 FLV can look washed out in the MKV.

Wannan yana dogara da abin da ke faruwa ga bidiyo. MKV zuwa MP4 ko MOV tare da daidaitattun diff yana kwafe bidiyon bidiyo ba tare da canzawa ba, don haka girman yana da nisa zuwa wurin asali.

The converter has no resolution cap of its own; the limit is the upload size allowed on your plan, and 4K, 8K and 60 fps files keep their resolution and frame rate unless you change them. MKV to MP4 or MOV with the default settings copies the video stream, which is fast at any resolution. Other pairs re-encode on CPU and the time grows with the pixel count, so a long 4K or 8K file takes much longer than the same length in 1080p.
