A HLS stream is a.m3u8 manifest pointing at a staircase of H.264 or HEVC segments at several bitrates, so the player can switch quality mid-playback.

Usually not. Most conversions keep one audio track, the one with the most channels (normally the main mix), re-encoded for the HLS 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 MOV with that track first (VLC or ffmpeg can do this), then convert it. HLS shine Apple's HTTP Live Streaming - ba fayil ba amma playlist tare da fayil na ɓangarorin kafofin watsa labarun.

Mene ne kodeki na fitarwa HLS ke amfani da shi bisa diff?
+
It depends on the HLS 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. HLS ba fayil ne mai saukewa guda ba - don a kiyaye shi ba da sadarwa dole ne a mushe shi zuwa cikin wani kwandon da'ira farko.
Ta yaya HDR (HDR10, Dolby Vision) zai iya tsira daga MOV zuwa HLS?
+
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 MOV can look washed out in the HLS.

Shin mai canza MOV zuwa HLS yana kula da abun ciki na 4K / 8K / 60fps?
+
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.
