Ga duk abin da kake son kiyayewa, na'am. WMV yana da alaka da wani zamani na baya na kayan aikin bidiyo kuma kayan aikin da ke karanta shi yana faruwa da sauri daga wayoyin hannu, masu bincike da tsarin aiki. Motsa bidiyo zuwa MKV yanzu, yayin da mai decoder mai tsafta ke nan, shi ne bambanci tsakanin wata arshiya da zaka iya buɗewa cikin shekaru goma da wata da ba za ka iya buɗewa ba.

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 WMV 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.

A wasu ma'aurata. MP4 zuwa MOV na riƙe duk wani labari na rubutu. AVI, WMV, MPEG, FLV, VOB da M4V zuwa MKV na riƙe duk wani labari na rubutu: an kwafe labaran rubutu ko an canja su zuwa SRT, kuma an kwafe labaran rubutu masu dauke da hotuna kamar DVD ko Blu-ray kamar yadda suke. MP4, MOV da WebM zuwa MKV suna riƙe kawai da labari na farko na rubutu (a matsayin ASS), kuma MP4 zuwa WebM yana riƙe da na farko kamar WebVTT. Wasu ma'aurata, ciki har da MKV zuwa MP4 ko MOV da WebM zuwa MP4, suna dauke da labari na farko na rubutu, kuma mai canja wurin ba zai rubuce su cikin hoton ba. Labaran rubutu da aka rubuce a baya suna zaune, saboda su ɓangare ne na firam ɗin bidiyo.

MKV shi ne mai sarrafa maɓallin maɓalli kawai wanda ke adana fayilolin da aka haɗa (TTF fonts for ASS subs, JPG cover art, fan-translated PDF inserts). Zuwa daga WMV zuwa MKV yana daure waɗannan maɓallan idan MKV bai zama MKV ba — maɓallan elemental na canjawa, amma nauyin da aka haɗa yana zaune a cikin tushen. Ka riƙe WMV a matsayin madadin idan kana dogara da maɓallan da aka haɗa.

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 WMV 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.
