MP4 pou FLV FAQ sou Konvèsyon
Ki jan mwen ka re-encode MP4 nan FLV san yo pa pèdi bon jan kalite videyo?
+
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 FLV output gets a codec its container supports: H.264 for MP4, MOV and MKV, VP9 for WebM. Preske chak MP4 nan forè a se H.264 videyo ak AAC son; kontenè a tou legalman depoze HEVC, AV1 ak VP9. FLV gen depoze Sorenson Spark oswa H.264 videyo ak MP3 oswa AAC son, enpak nan yon fòma stream ki fèt pou RTMP livrezon.
Èske mwen ka toujou enkòpore dosye a sou yon paj entènèt apre konvèsyon MP4 nan FLV?
+
Pa dirèkteman. MP4 jwe nan tout navigatè; FLV pa fè sa, se konsa yon paj ki enkòpore li retounen nan yon lyen telechaje oswa yon frame jwè vid. Si dosye a se destiné pou yon sit entènèt, kenbe MP4 pou entènèt la epi trete FLV kòm archive oswa edite kopi. Pa gen navigatè, telefòn oswa TV ka jwe FLV - nenpòt bagay ki toujou nan sa a kontenè dwe deplase soti nan li pou rete watchable.
Èske FLV la pral jwe san pwoblèm sou yon telefòn oswa yon televizyon?
+
Li ka pa. MP4 se dekode pa silisyòm dedike sou telefòn, tablèt ak televizyon, ki se poukisa li jwe san yo pa flate batri a. FLV anjeneral retounen nan dekodaj lojisyèl sou menm hardware - chaj CPU ki pi wo, yon aparèy pi cho, ak kadr tonbe sou materyèl 4K. Pou yon aparèy ki vize, MP4 se kontenè ki pi an sekirite pou rete nan.
Poukisa mwen ta dwe konvèti MP4 nan yon fòma pi ansyen tankou FLV?
+
Se paske anpil aparèy pa janm aprann anyen nouvo e pa janm pral aprann. DVD jwè, in-car head units, camcorder playback modes, industrial displays ak anpil ekipman broadcast ingest aksepte FLV e pa gen anyen lòt. Konvèsyon an se yon etap deliberan nan efisiens, achte nan echanj pou travay sou yon aparèy ki pa gen lòt opsyon. FLV a ba per-paket overhead te fè li ekselan nan streaming sou koneksyon ki pa fiab nan epòk li, ak archivals gwo li yo toujou egziste.
Ki codec videyo FLV ekspòtasyon an itilize?
+
It depends on the FLV 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. FLV se Flash Video kontenè ki te pote esansyèlman tout videyo sou entènèt la soti nan apeprè 2003 jiskaske Flash te dezaktive nan fen 2020.
Èske travès mwen an pral survive konvèsyon MP4 a FLV?
+
Yes, the main audio track comes through, re-encoded to a codec the FLV 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.
Èske mwen ka kenbe framerate orijinal la lè mwen konvèti MP4 nan FLV?
+
Yes. The frame rate is kept unless you change it: a 24 fps MP4 stays 24 fps in the FLV. 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.
Ki jan anpil gwosè dosye a pral chanje soti nan MP4 a FLV?
+
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.
Èske FLV dosye a pral jwe sou iPhone, Android, ak Smart TV?
+
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.
Konbyen tan li pran pou konvèti yon videyo 1 èdtan MP4 nan FLV?
+
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.
Ki sa ki se rezoud maksimòm sipòte pou MP4 a FLV?
+
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.
Èske MP4 videyo mwen an prive pandan konvèsyon an nan FLV?
+
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 FLV are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
