MP4 ka WebM FAQ Konversi
Kepiye aku bisa ngode ulang MP4 dadi WebM tanpa ilang kualitas video?
+
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 WebM output gets a codec its container supports: H.264 for MP4, MOV and MKV, VP9 for WebM. Sacara umum, MP4 dipaké pikeun nyimpen video H.264, audio AAC, sarta kodekan audio HEVC, AV1, VP9, sareng VP9.

Video codec apa sing digunakake output WebM?
+
It depends on the WebM 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. WebM nyaéta subset Matroska anu diterbitkeun ku Google dina taun 2010 khususna pikeun masihan HTML5 video kontener royalty-free.
Bakal trek audioku tetep urip sawise dikonversi saka MP4 dadi WebM?
+
Yes, the main audio track comes through, re-encoded to a codec the WebM 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.
Apa aku bisa nyimpen frekuensi bingkai asli nalika ngowahi MP4 dadi WebM?
+
Yes. The frame rate is kept unless you change it: a 24 fps MP4 stays 24 fps in the WebM. 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.
Ukuran file bakal ganti saengga saka MP4 dadi WebM?
+
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.
Apa file WebM bakal dimainake ing iPhone, Android, lan 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. WebM henteu cocog pikeun digunakeun di luar browser - editor video, galeri asli telepon, sareng Smart TV henteu ngartos.
Kepiye suwe kanggo ngowahi video MP4 1 jam dadi WebM?
+
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.
Resolusi paling dhuwur sing didhukung kanggo MP4 nganti WebM?
+
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.
MP4 videoku pribadi nalika dikonversi dadi WebM?
+
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 WebM are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
Apa aku bisa potong, potong, utawa ngolah nalika ngowahi MP4 dadi WebM?
+
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 WebM conversion. Trimming first is faster than re-encoding the whole MP4 just to drop unused footage.
Mengapa file WebM blur dibandingkan dengan sumber MP4?
+
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.
