MPG i MPEG Cwestiynau Cyffredin Trosi
Sut ydw i'n ail-amgodio MPG i MPEG heb golli ansawdd y fideo?
+
Upload your MPG 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 MPEG output gets a codec its container supports: H.264 for MP4, MOV and MKV, VP9 for WebM. Mae'r cynnwys yn fideo MPEG-1 neu MPEG-2 gyda sain MP2; mae'r amlgyfrwng a'r strwythur GOP yn debyg i ffeil.mpeg. Mae'r fideo yn MPEG-1 neu MPEG-2 gyda sain MP2 neu AC-3, wedi ei aml-droi i mewn i llif wedi ei ddylunio i'w ddatgodio gan feddalwedd swyddogaeth sefydlog.
A oes unrhyw newid pwynt rhwng dau fformat hen fel MPG a MPEG?
+
Dim ond os mae darn penodol o offer yn gofyn am y targed. Mae'r ddau fformat yn dod o'r un cyfnod cyn H.264, felly nid yw'r ddwy trosi yn prynu effeithlonrwydd, ansawdd neu ddibynadwyedd - mae'n prynu cydnawsedd gydag un dyfais benodol. Os yw'r nod yw cadw'r ffilm yn ddefnyddiol am gyfnod hir, trosi i gynhwysydd cyfredol yn hytrach na'r ochr. Mae MPG yn meddiannu pob terfyniad MPEG-2 — bitrate trwm, rhyng-gyswllt, dim isdeitlau meddal — yn ogystal â'r cylchdro o ddau estyniad ar gyfer un fformat. Mae MPEG-2 yn gofyn am tua 4 i 6 gwaith y bitrate o H.264 ar gyfer y ddelwedd un fath, ac mae ei gynnwys yn aml yn cael ei ddwyn, sy'n edrych yn ddargludadwy ar arddangosfeydd modern.
Pa codec fideo mae'r MPEG allbwn yn ei ddefnyddio?
+
It depends on the MPEG 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. Mae MPEG yma yn golygu llif rhaglen MPEG-1 neu MPEG-2, y fformat safonol ar gyfer CDau Fideo ac wedyn ar gyfer DVDau a theledu darlledu.
A fydd fy ngherddoriaeth yn goroesi trawsnewid MPG i MPEG?
+
Yes, the main audio track comes through, re-encoded to a codec the MPEG 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.
A allaf gadw'r gyfradd ffrâm wreiddiol wrth drosi MPG i MPEG?
+
Yes. The frame rate is kept unless you change it: a 24 fps MPG stays 24 fps in the MPEG. 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.
Faint fydd maint y ffeil yn newid o MPG i MPEG?
+
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 MPG 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.
A fydd y ffeil MPEG yn chwarae ar iPhone, Android, a 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. Mae llifoedd rhaglen MPEG yn cael eu datgodio gan bob chwaraewr DVD, set-top box a chain darlledu a adeiladwyd erioed, ac maent yn tolereiddio gwallau did yn ddewr.
Faint o amser mae trosi fideo MPG awr i MPEG yn ei gymryd?
+
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.
Beth yw'r cydraniad uchaf a gynhelir ar gyfer MPG i MPEG?
+
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 MPG can look washed out.
A yw fy MPG fideo yn breifat wrth drosi i MPEG?
+
Yes. Uploaded MPG files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted MPEG are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
A allaf torri, tocio, neu droi yn ystod y trawsnewid MPG i MPEG?
+
Not in the same step. Use /trim-video/ or /video-cutter/ to clip the MPG first, or /rotate-video/ to turn it, then run the MPG to MPEG conversion. Trimming first is faster than re-encoding the whole MPG just to drop unused footage.
Pam mae'r ffeil MPEG yn llythrennol yn ddull o'r ffynhonnell MPG?
+
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. MPG yw'r estyniad meddalwedd awdur DVD, mae camcorders hŷn a offerynnau mewnbwn darlledu yn ei adnabod, felly mae'n dal yn ddefnyddiol ar gyfer y pibellau hynny.
