MP4 chun MOV Ceisteanna Coitianta maidir le Comhshó
Conas a athchódaím MP4 go MOV gan caighdeán físe a chailleadh?
+
Upload your MP4 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 MOV output gets a codec its container supports: H.264 for MP4, MOV and MKV, VP9 for WebM. Is beagnach gach MP4 san fhiáine físeán H.264 le fuaim AAC; tá an coimeádán freisin go dlíthiúil HEVC, AV1 agus VP9. 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.
An féidir leis an MOV níos mó ná rian fuaime amháin a shealbhú?
+
Sea, agus is fíor-uasghrádú é thar MP4. MOV déileálann sé le gach sruth fuaime mar rian den chéad scoth, mar sin is féidir le meascán bunaidh teanga, dub agus tráchtaireacht stiúrthóra maireachtáil i gcomhad amháin leis an imreoir ag aistriú idir iad ar éileamh. Is MOV an fhormáid eagarthóirí gairmiúla a iarraidh ar, toisc go maireann sé arís agus arís eile babhta-turas trí Final Cut Pro, Premiere agus DaVinci Réiteach gan caillteanas giniúna.
An féidir liom an comhad a leabú fós ar leathanach gréasáin tar éis MP4 a thiontú go MOV?
+
Ní go díreach. Seinnfidh MP4 inlíne i ngach brabhsálaí; ní sheinnfidh MOV, mar sin tiocfaidh nasc íosluchtaithe nó fráma folamh imreora ar leathanach ina leabaítear é. Má tá an comhad le haghaidh suíomh gréasáin, coinnigh an MP4 don Ghréasán agus déileáil leis an MOV mar chóip chartlainne nó eagarthóireachta. Tá comhaid MOV mór, agus lasmuigh den Apple éiceachóras tacaíocht athsheinm patchier ná MP4 - tógann Android níos sine agus beidh roinnt teilifíseáin Cliste diúltú dóibh.
Cén codec físe a úsáideann an MOV aschur?
+
It depends on the MOV 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 MOV Apple QuickTime coimeádán, shipped i 1991 agus fós an fhormáid iPhone, iPad nó Final Gearr Pro amlíne scríobhann de réir réamhshocraithe.
An mairfidh mo rian fuaime MP4 go MOV comhshó?
+
Yes, the main audio track comes through, re-encoded to a codec the MOV 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 MP4 a thiontú go MOV?
+
Yes. The frame rate is kept unless you change it: a 24 fps MP4 stays 24 fps in the MOV. 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 MP4 go MOV?
+
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 MP4 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 MOV 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.
Cé chomh fada agus a thógann sé físeán 1 uair an chloig MP4 a thiontú go MOV?
+
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 MP4 go MOV?
+
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 MP4 can look washed out.
An bhfuil mo MP4 físeán príobháideach le linn comhshó go MOV?
+
Yes. Uploaded MP4 files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted MOV 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 MP4 go MOV comhshó?
+
Not in the same step. Use /trim-video/ or /video-cutter/ to clip the MP4 first, or /rotate-video/ to turn it, then run the MP4 to MOV conversion. Trimming first is faster than re-encoding the whole MP4 just to drop unused footage.
