Shin waƙoƙin sauti masu yawa za su iya tsira daga canji daga MKV zuwa MP4?

Usually not. Most conversions keep one audio track, the one with the most channels (normally the main mix), re-encoded for the MP4 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 MKV with that track first (VLC or ffmpeg can do this), then convert it. MP4 ne ISO/IEC 14496-14, standardized a cikin 2001 da kuma dauke daga irin QuickTime akwatin zane MOV amfani.

Mene ne kodeki na fitarwa MP4 ke amfani da shi bisa diff?
+
It depends on the MP4 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.
Ta yaya HDR (HDR10, Dolby Vision) zai iya tsira daga MKV zuwa MP4?
+
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 MKV can look washed out in the MP4.
