MOV chun M4V Ceisteanna Coitianta maidir le Comhshó
Conas a athchódaím MOV go M4V gan caighdeán físe a chailleadh?
+
Upload your MOV file and set Quality to High Quality in the conversion options. That re-encodes the video at the highest quality setting (CRF 18 for H.264 and VP9 output), which keeps the most detail at the cost of a larger file. The default, Balanced, uses the standard setting. The M4V output gets a codec its container supports: H.264 for MP4, MOV and MKV, VP9 for WebM. A MOV iompraíonn de ghnáth H.264 nó HEVC le haghaidh seachadadh, nó ProRes nuair a bhíonn sé ina mháistir eagarthóireacht, in éineacht le AAC nó PCM neamh-chomhbhrúite fuaime. Struchtúrtha is M4V MP4 - H.264 nó HEVC le AAC - le roghnach Apple FairPlay DRM agus iTunes meiteashonraí chaibidil.
Cén codec físe a úsáideann an M4V aschur?
+
It depends on the M4V 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. Is M4V Apple ar éagsúlacht MP4, a úsáidtear ag iTunes agus an app Apple TV do scannáin agus eipeasóid teilifíse.
An mairfidh mo rian fuaime MOV go M4V comhshó?
+
Yes, the main audio track comes through, re-encoded to a codec the M4V container plays, for example AAC in MP4 and MOV or Opus in WebM. Most conversions keep only that one track (the one with the most channels), so alternate languages and commentary are dropped. MP4 to MOV, and AVI, WMV, MPEG, FLV, VOB or M4V to MKV, keep every audio track.
An féidir liom an ráta fráma bunaidh a choinneáil nuair a dhéantar MOV a thiontú go M4V?
+
Yes. The frame rate is kept unless you change it: a 24 fps MOV stays 24 fps in the M4V. The Frame Rate setting can also convert to 60, 30 or 24 fps. It changes the rate only; it does not deinterlace the video or remove 3:2 pulldown.
Cé mhéad a athróidh méid an chomhaid ó MOV go M4V?
+
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.
An mbeidh an comhad M4V ag imirt ar iPhone, Android, agus Smart TVs?
+
MP4 with H.264 plays on practically every phone, browser and TV. MOV with H.264 plays on Apple devices and most TVs but not on every older Android phone. MKV needs an app such as VLC on iOS, and WebM is at home in browsers. There is no device preset on this page, so choose the target format your device supports. Coinníonn M4V marcóirí chaibidil, saothar ealaíne agus rianta fotheideal sa chruth a bhfuil an app Apple TV ag súil, a chailleann MP4 plain go minic. Ní féidir le ceannacháin DRM-chosanta M4V a thiontú ag rud ar bith; ach tá comhaid M4V gan chosaint convertible, agus ní mór imreoirí neamh-Apple go minic ar an síneadh athainmnithe.
Cé chomh fada agus a thógann sé físeán 1 uair an chloig MOV a thiontú go M4V?
+
There is no fixed time: it depends on the length, the resolution and the target format. Conversions run on our servers' CPUs with software encoders; there is no GPU acceleration. MKV to MP4 or MOV with the default settings copies the video stream and is the quickest. A re-encode to H.264 takes longer, and WebM (VP9) is the slowest target, several times slower than H.264 in our tests.
Cad é an réiteach uasta a thacaítear le haghaidh MOV go M4V?
+
The converter has no resolution cap of its own; the limit is the upload size allowed on your plan, and the resolution stays as it is unless you choose 1080p, 720p or 480p. 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 untouched. A re-encode drops the HDR10 mastering metadata, 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.
An bhfuil mo MOV físeán príobháideach le linn comhshó go M4V?
+
Yes. Uploaded MOV files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted M4V are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
An féidir liom barr, trim, nó rothlú le linn an MOV go M4V comhshó?
+
Not in the same step. Use /trim-video/ or /video-cutter/ to clip the MOV first, or /rotate-video/ to turn it, then run the MOV to M4V conversion. Trimming first is faster than re-encoding the whole MOV just to drop unused footage.
Cén fáth go bhfuil an comhad M4V blurry i gcomparáid leis an bhfoinse MOV?
+
Usually the output was compressed harder than the source. Open the conversion options, choose High Quality under Quality, keep Resolution at Original and convert again. There is no CRF or bitrate field on this page; High Quality is the setting that keeps the most detail.
An láimhseálann an tiontaire MOV go M4V fotheidil?
+
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.
