WMV → MKV

Heoi, he whakawhānui tūturu i runga i te WMV. MKV e whakaaro ana ki ia rerenga oro hei rererangi ā-ira tuatahi, kia noho ai te whāranu reo taketake, te tāruatanga me te kōrero a te kaiwhakahaere i tētahi pūranga kotahi me te kaipāpāho e whakawhiti ana i waenganui i a rātau i te tono. Ko MKV te pūranga kōwhiringa o te kōwhiringa nā te mea ka pupuri i ngā aho whakatere, ngā whakahua whakahua, ngā tohu wāhanga me ngā toi kāwai i roto i tētahi pūranga kotahi.

Tata tonu ki te DRM i ngā wā katoa. Ko ētahi WMV ngā pūranga e whakawaeheretia ana i te taumata bitstream e te puna, i te pūmanawa rānei i tukuna ai rātou, ā, kāore e taea te whakawaehere i tētahi rerenga whakawaeheretia e tātau, e tētahi atu rānei me te kore te kī ā-whakahaere. Ko ngā pūranga i whakahuatia e koe, i whakawātea, i whakawāteatia rānei i te whakarerekētanga kāore i te parea; kāore e taea e te hoko ā-whakahaere, ā, kāore e taea e te kaiwhakarere te whakaū i tētahi atu mea. He tino tūkino te WMV: e hiahiatia ana e macOS, iOS, Android me ia kaiwhaiwhai ngā whakakōrero tuatoru, ā, ko ētahi pūranga WMV e mau ana i te DRM kāore e taea te tahuri.

Mō ētahi mea e hiahia ana koe ki te pupuri, ā, kei te WMV tētahi whakatupuranga o mua o ngā utauta ataata, ā, ko te pūmanawa e ako ana i a ia e ngaro tonu ana i ngā pūrongo, ngā kiritaki me ngā pūnaha whakahaere. Ko te neke i te pūwhitinga ki MKV ināianei, ahakoa kei te tīariari tonu tētahi whakakōrero mārō, ko te rerekētanga i waenganui i tētahi pūranga ka taea e koe te whakatupuranga tekau tau me tētahi kāore e taea e koe.

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. Ko MKV ko Matroska, he pūrere tūwhera i hangaia i te tau 2002 me te kore whakawhanake ā-whakahaere, ā, kāore he taumata ki te mea ka taea e ia te pupuri.

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.

Ko MKV te mea anake e pupuri ana i ngā pūkete whakapiripiri (ngā tātuhi TTF mō ngā tātai ASS, ngā toi kāwai JPG, ngā tāurunga PDF i whakamāoritia). E haere ana mai i te WMV ki te MKV ka whakapeka ēnei tātai ina kore te MKV he MKV — ka tahuri ngā rerenga taketake, engari ka noho te utu whakapiripiri i te pūtake. Whakataki WMV hei tiaki i ētahi atu tātai mēnā e whakawhirinaki ana ki ngā tātai whakapiripiri.

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. Tata tonu ki te kore e tautokona e MKV ngā pūrere māori — ko ngā pūrongo, ngā kaituhi me ngā pouaka whakaata e hiahiatia ana e VLC, he remux rānei i mua i te whakataetae.

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.

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 WMV 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.
