WebM pou AV1 FAQ sou Konvèsyon
Ki jan mwen ka re-encode WebM nan AV1 san yo pa pèdi bon jan kalite videyo?
+
Upload your WebM 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 AV1 output gets a codec its container supports: H.264 for MP4, MOV and MKV, VP9 for WebM. WebM se volontèman epè: VP8 oswa VP9 videyo (AV1 plis dènyèman) ak Vorbis oswa Opus son, ak pa gen anyen lòt. AV1 se yon codec, pa yon kontenè - bitstream anjeneral vwayaje andedan MP4 oswa WebM, pare ak Opus oswa AAC son.
Èske AV1 la pral jwe san pwoblèm sou yon telefòn oswa yon televizyon?
+
Li ka pa. WebM se dekode pa silisyòm dedike sou telefòn, tablèt ak televizyon, ki se poukisa li jwe san yo pa flate batri a. AV1 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, WebM se kontenè ki pi an sekirite pou rete nan. AV1 enkodaj se vit, ak dekodè hardware sèlman te parèt nan telefòn ak televizyon soti nan sou 2020 an pou pi devan - aparèy ki pi ansyen yo tounen nan pouvwa-soti nan dekodaj lojisyèl.
Èske AV1 se yon kontenè oswa yon codec, epi èske sa chanje sa mwen jwenn tounen?
+
Li chanje sa pou espere nan dosye a sortie. Yon bò nan konvèsyon sa a non yon encodage piske yon wrapper, konsa sa ki rive tounen se ke bitstream andedan nenpòt ki kontenè ki pi bon pou li - nòmalman MP4 oswa MKV. L' extension reflete kontenè a; codec se sa ki reyèlman detèmine gwosè a dosye a ak kote li pral jwe.
Ki codec videyo AV1 ekspòtasyon an itilize?
+
It depends on the AV1 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. AV1 se yon codec videyo san restriksyon ki te lage pa Alliance for Open Media an 2018 kòm yon pwochen nan VP9.
Èske track mwen an ap survive konvèsyon WebM a AV1?
+
Yes, the main audio track comes through, re-encoded to a codec the AV1 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 WebM nan AV1?
+
Yes. The frame rate is kept unless you change it: a 24 fps WebM stays 24 fps in the AV1. 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 WebM a AV1?
+
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 WebM 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 AV1 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. AV1 bay sou 30% pi bon konpresyon pase H.264 nan menm kalite a ak pote pa gen okenn frè lisans, ki se poukisa YouTube ak Netflix pouse li.
Konbyen tan li pran pou konvèti yon videyo 1 èdtan WebM nan AV1?
+
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 ki sipòte pou WebM a AV1?
+
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 WebM can look washed out.
Èske WebM videyo mwen an prive pandan konvèsyon an nan AV1?
+
Yes. Uploaded WebM files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted AV1 are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
Èske mwen ka koupe, triye, oswa ranje pandan konvèsyon WebM a AV1?
+
Not in the same step. Use /trim-video/ or /video-cutter/ to clip the WebM first, or /rotate-video/ to turn it, then run the WebM to AV1 conversion. Trimming first is faster than re-encoding the whole WebM just to drop unused footage.
AV1 se yon fòma konpresyon videyo ouvè, san redevances ki fèt pou difizyon videyo efikas sou entènèt la. Li bay efikasite konpresyon segondè san yo pa konpwomèt bon jan kalite vizyèl.
