MP4 pou FLV FAQ sou Konvèsyon
Ki jan mwen ka re-encode MP4 nan FLV san pèdi bon jan kalite vizib?
+
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.
Ki codec FLV ekspòtasyon an itilize pa default?
+
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.
Èske travès mwen an ap 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 diferans ki genyen ant MP4 ak 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 nan navigatè ak sou aparèy mobil?
+
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.
Ki sa ki tan li pran pou konvèti yon 1-èdtan MP4 dosye 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?
+
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.
Èske mwen ka kouvri oswa triye pandan konvèsyon MP4 a FLV?
+
Pa nan menm etap la — itilize /trim-video/ oswa /resize-video/ pou koupe ak tranpe MP4 an premye, Lè sa a, mete nan liy MP4 → FLV etap la. Fè yo nan seri se pi vit pase re-enkode tout dosye a jis pou koupe segond soti nan bout yo.
Poukisa se FLV dosye a blurry oswa blocky konpare ak MP4 sous?
+
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.
Èske konvètisè MP4 a FLV la sipòte sous-titres?
+
On some pairs. MP4 to MOV keeps every text subtitle track. AVI, WMV, MPEG, FLV, VOB and M4V to MKV keep every subtitle track: text subtitles are copied or converted to SRT, and picture-based subtitles such as DVD or Blu-ray ones are copied as they are. MP4, MOV and WebM to MKV keep only the first subtitle track (as ASS), and MP4 to WebM keeps the first one as WebVTT. Other pairs, including MKV to MP4 or MOV and WebM to MP4, drop subtitle tracks, and the converter does not burn them into the picture. Subtitles that are already burned in stay, because they are part of the video frames.
