Nola birkodetu MP4 3GP(e)ra bideo-kalitatea galdu gabe?
+
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 3GP output gets a codec its container supports: H.264 for MP4, MOV and MKV, VP9 for WebM. MP4 formatu gehienak H.264 bideoa AAC audioarekin, eta HEVC, AV1 eta VP9 ere legez onartzen ditu. 3GPk H.263 edo MPEG-4 Part 2 bideoa du AMR banda estuko hizketa audioarekin, bit-tasa minimoarentzat egokituta, kalitaterik gabe.
Ez zuzenean. MP4 arakatzaile guztietan lineaz kanpo erreproduzitzen da; 3GP ez du egiten, beraz, kapsulatutako orrialde batek deskarga-esteka edo erreproduzitzaile-marko huts bat itzultzen du. Fitxategia webgune baterako bada, gorde MP4 weberako eta tratatu 3GP artxibo edo edizio-kopia gisa. 3GPk muga du bereizmen txikietan eta mono hizketa-mailako audioan; eskalatzeak ez du berreskuratuko inoiz grabatu ez ziren xehetasunak.
It depends on the 3GP 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. 3GP 3GPPk telefono mugikorren lehen bertsioetarako estandarizatu zuen edukiontzia da, bideoak 176x144 pantaila eta 2G datu-plan batean sartu behar zirenean.
Yes, the main audio track comes through, re-encoded to a codec the 3GP 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.
Yes. The frame rate is kept unless you change it: a 24 fps MP4 stays 24 fps in the 3GP. 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.
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.
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. 3GP fitxategiak txikiak dira eta dekodetzen dira pentsa daitekeen hardwarerik ahulenean, eta horregatik telefono mugikorrek eta terminal txikiek oraindik grabatzen dute.
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.
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.
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 3GP are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
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 3GP conversion. Trimming first is faster than re-encoding the whole MP4 just to drop unused footage.
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. MP4a ahalik eta entregatze helburu seguruena da, azken hamarkadan eraikitako telefono, nabigatzaile, kontsola, editore eta Smart TV guztiek software gehigarririk gabe erreproduzitzen dute.
