MKV Tuhinga o mua MP4 Ngā Pātai Auau mō te Tahuritanga

He pēhea te tahuri i a au i te MKV ki te MP4 me te kore whakawaehere i te rerenga ataata?

There is no stream-copy switch on this page. A few pairs copy a compatible video stream into the MP4 container without re-encoding it, MKV to MP4 among them, which is quick and loses no quality. Most pairs re-encode the video. He pūāhua-pūāhua te MKV: H.264, HEVC, VP9 me te whakaaturanga AV1 e noho ai te AAC, FLAC, Opus, DTS, te oro Dolby rānei i roto i te pūranga kotahi. Tata tonu ki ia MP4 i te mohoao he ataata H.264 me te oro AAC; kei roto hoki i te kāwai he HEVC, AV1 me VP9.

Ka tākaro te MP4 i roto i tētahi kaitiaki i te wā kāore te MKV?

Heoi, ā, ko te tikanga ko te take katoa mō te tahuritanga. Ko tētahi MKV i whakawāteatia i roto i tētahi pātaka whatunga, e whakaatu ana i tētahi kaiwhakaari whakarewa, he whakahau rānei i tētahi whakataki, nā te mea kāore he whakawātea mō te whakawāteatanga. MP4 e whakawāteatia ana i roto i te huānga o te HTML5 māori me te kore tātai, me te kore taupānga o waho. Ko MP4 te ūnga whakawhiwhinga tino haumaru rawa - ko ia whatunga, kaitiaki, pāpāho, kaiwhakawhanake me te Smart TV i hangaia i roto i te tekau tau i muri mai e whakawhiwhia ana ki te kore pūmanawa tāpiri.

Ko te MKV me te MP4 he kāwai hōu — he aha te mea me pupuri i a au?

E pupuri ana i ngā ōritetanga i reira ka haere te faila, nā te mea kāore e pai ake i te whakarārangi. Ko tētahi o ēnei e rua e hangaia ana mō te ōritetanga whakapāpāho, ā, ko tētahi atu mō te pupuri i ngā mea katoa ka taea e tētahi faila te pupuri, ā, ka whakawhitiwhiti rātou ki a rātou anō i runga i taua raina. Ko te whakautu ā-pūnaha mō te nuinga o ngā puna ko te pūranga i roto i te pūrere āhuahira-tōtika me te whakawātea ki te ōrite 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.

Ka ora te oro-maha-rangirangi ki te tahuritanga MKV ki 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. Ko MP4 te ISO/IEC 14496-14, i paerewa i te tau 2001, ā, i puta mai i te āhua o te kāwai pēnei i te QuickTime e whakamahia ana e MOV.

E tiakina ana ngā pūrere subtitles ina tahuritia te MKV ki te MP4?

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.

He aha mo ngā whakataki MKV (whakatika, whakataki) ina haere mai te MKV ki te MP4?

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 MKV ki te MP4 ka whakapeka ēnei tātai ina kore te MP4 he MKV — ka tahuri ngā rerenga taketake, engari ka noho te utu whakapiripiri i te pūtake. Whakataki MKV hei tiaki i ētahi atu tātai mēnā e whakawhirinaki ana ki ngā tātai whakapiripiri.

He aha te pūrere pūrere e whakamahia ana e te MP4?

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. Ko MP4 anake e tautoko ana i tētahi hanga tuhituhi ā-whānui (mov_text), ā, kāore te oro-maha i te whakawhirinaki i waho o ngā kaiwhakaari papatahi.

He pēhea te ora o HDR (HDR10, Dolby Vision) mai i te MKV ki te 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.

He aha te mea he iti iho / nui ake te MP4 o ahau i te MKV i muri i te tahuri?

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 MKV 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.

E whakahaere ana te MKV ki te MP4 te ihirangi 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 quick 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.
