AV1 i MP4 Cwestiynau Cyffredin Trosi

Sut ydw i'n ail-amgodio AV1 i MP4 heb golli ansawdd y fideo?

Upload your AV1 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 MP4 output gets a codec its container supports: H.264 for MP4, MOV and MKV, VP9 for WebM. Codec yw AV1, nid cynhwysydd - mae'r bitstream yn teithio o fewn MP4 neu WebM fel arfer, wedi'i gyfuno â sain Opus neu AAC. Mae bron pob MP4 yn y byd naturiol yn cynnwys fideo H.264 gyda sain AAC; mae'r cynhwysydd hefyd yn cynnwys HEVC, AV1 a VP9 yn gyfreithiol.

A yw MP4 yn gynhwysydd neu codec, a a yw hynny'n newid beth dwi'n ei gael yn ôl?

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 yn gyffredin. Mae'r estyniad yn adlewyrchu'r cynhwysydd; y codec yw'r hyn sy'n penderfynu maint y ffeil a ble bydd yn chwarae.

Pa codec fideo mae'r MP4 allbwn yn ei ddefnyddio?

It depends on the MP4 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. MP4 yw ISO/IEC 14496-14, wedi ei safonoli yn 2001 ac yn deillio o'r un cynllun blwch QuickTime a ddefnyddir gan MOV.

A fydd fy ngherddoriaeth yn goroesi trawsnewid AV1 i MP4?

Yes, the main audio track comes through, re-encoded to a codec the MP4 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 or VOB to MKV with the default settings, keep every audio track.

A allaf gadw'r gyfradd ffrâm wreiddiol wrth drosi AV1 i MP4?

Yes. The frame rate is kept unless you change it: a 24 fps AV1 stays 24 fps in the MP4. 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 AV1 i MP4?

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 AV1 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 MP4 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. MP4 yw'r targed dosbarthu mwyaf diogel posibl - mae pob ffôn, porwr, consol, golygydd a Smart TV a adeiladwyd yn y degawd diwethaf yn chwarae MP4 heb feddalwedd ychwanegol. MP4 yn cynnal dim ond un fformat is-deitlau (mov_text) a adnabyddir yn eang, ac mae sain aml-trac yn anhyblyg tu allan i chwaraewyr penbwrdd.

Faint o amser mae trosi fideo AV1 awr i MP4 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 AV1 i MP4?

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 AV1 can look washed out.

A yw fy AV1 fideo yn breifat wrth drosi i MP4?

Yes. Uploaded AV1 files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted MP4 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 AV1 i MP4?

Not in the same step. Use /trim-video/ or /video-cutter/ to clip the AV1 first, or /rotate-video/ to turn it, then run the AV1 to MP4 conversion. Trimming first is faster than re-encoding the whole AV1 just to drop unused footage.

Pam mae'r ffeil MP4 yn llythrennol yn ddull o'r ffynhonnell AV1?

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. Mae AV1 yn darparu cywasgu 30% gwell na H.264 ar yr un ansawdd ac nid yw'n cario unrhyw gostau trwydded, sy'n golygu mai YouTube a Netflix sy'n ei bwyso.
