MP4 a M4V Preguntas frecuentes sobre a conversión
Como recodificar MP4 a M4V sen perder a calidade do vídeo?
+
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 M4V output gets a codec its container supports: H.264 for MP4, MOV and MKV, VP9 for WebM. Case todos os MP4 na natureza son vídeos H.264 con audio AAC; o contedor tamén contén legalmente HEVC, AV1 e VP9. Estruturalmente un M4V é un MP4 — H.264 ou HEVC con AAC — con metadatos de capítulos de Apple FairPlay DRM e iTunes opcionais.
Pode o M4V conter máis dunha pista de son?
+
Si, e é unha verdadeira actualización de MP4. M4V trata cada fluxo de son como unha pista de primeira clase, polo que unha mestura na lingua orixinal, unha dobraxe e un comentario do director poden vivir nun ficheiro co reprodutor trocando entre eles segundo o precise. M4V mantén os marcadores de capítulo, ilustracións e pistas de subtítulos na forma que esperaplicación Apple TV, que o MP4 normal perde a miúdo.
Podo incorporar o ficheiro nunha páxina web despois de converter MP4 en M4V?
+
Non directamente. MP4 reproduce inline en todos os navegadores; M4V non, polo que unha páxina que o incorpore recae nunha ligazón de descarga ou nunha moldura baleira do reprodutor. Se o ficheiro está destinado a un sitio web, manteña o MP4 para a web e trate o M4V como copia de arquivo ou edición. As compras de M4V protexidas por DRM non poden ser convertidas por nada; só os ficheiros M4V non protexidos son convertibles, e os reprodutores que non son de Apple a miúdo precisan cambiar o nome da extensión.
Que códec de vídeo usa a saída M4V?
+
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. M4V é a variante de Apple de MP4, usada por iTunes e a aplicación Apple TV para películas e episodios de TV.
Sobrevivirá a miña pista de son á conversión de MP4 a M4V?
+
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.
Podo manter a taxa de fotogramas orixinal ao converter MP4 a M4V?
+
Yes. The frame rate is kept unless you change it: a 24 fps MP4 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.
Canto cambiará o tamaño do ficheiro se vai de MP4 a 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 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.
Reproducirase o ficheiro M4V en iPhone, Android e 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.
Canto tempo leva converter un vídeo de MP4 horas en 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.
Cal é a resolución máxima soportada para MP4 a 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 MP4 can look washed out.
É privado o meu MP4 vídeo durante a conversión a M4V?
+
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 M4V are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
Podo recortar, recortar ou xirar durante a conversión de MP4 a M4V?
+
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 M4V conversion. Trimming first is faster than re-encoding the whole MP4 just to drop unused footage.
M4V é un formato de ficheiro de vídeo desenvolvido por Apple. É semellante ao MP4 e úsase habitualmente para a reprodución de vídeos en dispositivos Apple.
