AVI i MKV Cwestiynau Cyffredin Trosi
Sut ydw i'n ail-amgodio AVI i MKV heb golli ansawdd y fideo?
+
Upload your AVI 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 MKV output gets a codec its container supports: H.264 for MP4, MOV and MKV, VP9 for WebM. Mae ffeiliau AVI yn henach na codecau modern: disgwylwch MPEG-4 Part 2 (DivX/Xvid), Motion JPEG neu ffrâm di-gywasgu crai yn hytrach na H.264. Mae MKV yn annibynnol ar godec: mae fideo H.264, HEVC, VP9 ac AV1 yn sefyll yn hapus wrth ochr AAC, FLAC, Opus, DTS neu sain Dolby yn yr un ffeil.
Mae fy AVI recordiad wedi ei rannu i rannau rhifedig - a oes gan MKV yr un terfyn?
+
Na, a dyna un o'r rhesymau gwell i symud. Mae gan y AVI gynhwysydd derfyn ffeil sengl ymarferol y mae recordiadau hir neu didrwch uchel yn rhedeg yn uniongyrchol i mewn iddo, sy'n union pam mae hen gatiau'n dod fel rhan1, rhan2, rhan3. Nid oes gan MKV unrhyw derfyn cyfatebol, felly gellir ail-uniad y darnau i mewn i un ffeil parhaus. Nid oes gan AVI gynhaliaeth naturiol ar gyfer codecau modern, cyfradd ffrâm amrywiol, isdeitlau meddal neu ffeiliau dros 4 GB heb rwystrau, a'i dros-bwysau fesul darn yn blocio'r ffeil.
A allaf ychwanegu isdeitlau dewisadwy pan fo'r ffeil yn MKV?
+
Ie. Nid oes gan AVI unrhyw gerddoriaeth is-deitlau meddal defnyddiol, felly roedd rhaid llosgi is-deitlau ar gyfer cynnwys AVI i'r ddelwedd neu eu cludo fel ffeil sidecar ar wahân. Mae gan MKV is-deitlau fel eu llif dewisadwy eu hunain, felly ar ôl trawsnewid gallwch atodi trac SRT y gall y gwelydd ei droi ymlaen, ei droi i ffwrdd neu ei ail-stilio.
A yw'n werth trosi hen recordiadau AVI i MKV o gwbl?
+
I unrhyw beth rydych chi'n bwriadu cadw, ie. Mae AVI yn perthyn i genhedlaeth gynharach o offer fideo a'r meddalwedd sy'n ei ddarllen yn diflannu'n gyson o ffôn, porwyr a systemau gweithredu. Symud y ffilm i MKV nawr, tra bod datgodiwr glan yn dal i fodoli, yw'r gwahaniaeth rhwng archif y gallwch ei agor mewn degawd a'r un na allwch. MKV yw'r cynhwysydd archif dewisol oherwydd mae'n storio traciau sain diderfyn, isdeitlau meddal, marciau pennod a lluniau cylchdro mewn un ffeil.
Pa codec fideo mae'r MKV allbwn yn ei ddefnyddio?
+
It depends on the MKV 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. Matroska yw MKV, cynhwysydd agored a ddyluniwyd yn 2002 heb gyfyngiadau trwydded na therfyn ar yr hyn y gall ei gynnwys.
A fydd fy ngherddoriaeth yn goroesi trawsnewid AVI i MKV?
+
Yes, the main audio track comes through, re-encoded to a codec the MKV 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 AVI i MKV?
+
Yes. The frame rate is kept unless you change it: a 24 fps AVI stays 24 fps in the MKV. 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 AVI i MKV?
+
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 AVI 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 MKV 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. Nid oes gan MKV bron unrhyw gynhaliaeth caledwedd naturiol - mae angen VLC neu remux ar ffôn, porwr a theledu fel arfer cyn y gallant ei chwarae.
Faint o amser mae trosi fideo AVI awr i MKV 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 AVI i MKV?
+
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 AVI can look washed out.
A yw fy AVI fideo yn breifat wrth drosi i MKV?
+
Yes. Uploaded AVI files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted MKV are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
