MOV → HLS

Ie, a dyna'r rheswm am y trawsnewid yn aml. Mae MOV wedi ei fewnosod mewn tudalen we naill ai'n dangos chwaraewr wedi torri neu'n gorfodi lawrlwytho, oherwydd nad oes gan borwyr ddatgodiwr ar ei gyfer. HLS yn chwarae mewnlin drwy'r elfen fideo HTML5 naturiol heb unrhyw ategyn na rhaglen allanol. Mae HLS yn addasu i bandwidth y gwelydd mewn amser real ac yw'r unig fformat llif Safari a iOS yn cefnogi'n naturiol.

Mae'n newid beth i ddisgwyl o'r ffeil allbwn. Mae un ochr o'r trawsnewid hwn yn enwi amgodiad yn hytrach na chylchdroi, felly mae'r hyn sy'n dod yn ôl yn y bitstream tu mewn i'r cynhwysydd sy'n addas iddo orau - MP4 neu MKV fel arfer. Mae'r estyniad yn adlewyrchu'r cynhwysydd; y codec yw'r hyn sy'n penderfynu maint y ffeil a ble bydd yn chwarae.

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 yw Llif HTTP Byw Apple - nid ffeil ond rhestr chwarae ynghyd â phlygell o rannau meddalwedd byr.

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.

MKV yw'r unig gynhwysydd prif ffrwd sy'n storio ffeiliau atodedig hap (ffontiau TTF ar gyfer is-deitl ASS, delweddau cylchgrawn JPG, mewnosodiadau PDF wedi'u cyfieithu gan y ffan). Mae mynd o MOV i HLS yn taflu'r atodiadau hyn pan nad yw HLS yn MKV — mae'r llifoedd sylfaenol yn trosi, ond mae'r llwyth atodedig yn aros yn y ffynhonnell. Cadwch MOV fel copïau wrth gefn os ydych yn dibynnu ar ffontiau atodedig.

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. Nid yw HLS yn ffeil lawrlwythadwy sengl - i'w gadw all-lein mae angen ei muxed yn ôl i mewn i gynhwysydd arferol yn gyntaf.

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.

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 MOV 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.

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.
