Nola birkodetu AVI MPG(e)ra bideo-kalitatea galdu gabe?
+
Upload your AVI 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 MPG output gets a codec its container supports: H.264 for MP4, MOV and MKV, VP9 for WebM. AVI fitxategiak kodeke modernoen aurretik sortu ziren: MPEG-4 Part 2 (DivX/Xvid), Motion JPEG edo konprimitu gabeko fotograma gordinetatik abiatuta, H.264 baino. MPEG-1 edo MPEG-2 bideoa MP2 audioarekin; muxing-a eta GOP egitura.mpeg fitxategiaren berdinak dira.
Nire AVI grabazioak zati zenbakidunetan banatuta daude. MPGk muga bera du?
+
Ez, eta hori da mugitzeko arrazoi hoberenetako bat. AVI edukiontziak fitxategi bakar baten muga praktikoa du, bit-tasa handiko grabazioak zuzenean sartu ahal izateko, eta hori da grabatutako zati zaharrak 1. zatia, 2. zatia, 3. zatia bezala iristeagatik. MPG ez du muga baliokiderik, beraz, zatiak fitxategi jarraitu batean elkartu daitezke. AVIk ez du kodeke modernoen euskarri natiborik, fotograma-tasa aldakorra, azpititulu bigun edo 4 GB baino gehiagoko fitxategiak hack-ik gabe, eta zati bakoitzeko gainkargak fitxategia handitzen du.
Bi formatu zaharren artean (AVI eta MPG) bihurtzen den punturik ba al dago?
+
Ekipamendu-zati jakin batek helburua eskatzen badu bakarrik. Bi formatu H.264 aurreko garai berekoak dira, beraz, bikoizteak ez du eraginkortasuna, kalitatea edo etorkizunerako segurtasuna erosten, gailu jakin batekin bateragarritasuna erosten du. Filma luzean erabilgarria izatea helburua bada, uneko edukiontzian bihurtu, ez albokoan. MPGk MPEG-2ren muga guztiak heredatzen ditu: bit-tasa handia, tartekatzea, azpititulurik ez, eta formatu bakarraren bi hedapenen nahasketa.
Zein bideo-kodeke erabiltzen du MPG irteerak?
+
It depends on the MPG 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. MPG MPEG programaren korronte bera da.mpeg bezala — hiru letrako luzapena DOS garaian trunkatua da, ez formatu desberdin bat.
Nire audio-pistak iraungo du AVI-tik MPG-ra bihurtzean?
+
Yes, the main audio track comes through, re-encoded to a codec the MPG 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.
Mantendu al dezaket jatorrizko fotograma-emaria AVI MPG bihurtzean?
+
Yes. The frame rate is kept unless you change it: a 24 fps AVI stays 24 fps in the MPG. 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.
Zenbat aldatuko da fitxategiaren tamaina AVI(e)tik MPG(e)ra?
+
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 AVI 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.
MPG fitxategia iPhone, Android eta Smart TVetan erreproduzituko da?
+
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. MPG DVDak sortzeko softwarearen luzapen bat da, kamera zaharrek eta broadcast ingest tresnek onartzen dutena, beraz, kanal horietan erabilgarria izaten jarraitzen du.
Zenbat denbora behar da ordubeteko AVI bideo bat MPG bihurtzeko?
+
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.
Zein da AVI eta MPG artean onartutako gehienezko bereizmena?
+
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 AVI can look washed out.
Nire AVI bideoa pribatua da MPG bihurtzean?
+
Yes. Uploaded AVI files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted MPG are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
Ebaki, moztu edo biratu dezaket AVI-(e)tik MPG-(e)ra bihurtzean?
+
Not in the same step. Use /trim-video/ or /video-cutter/ to clip the AVI first, or /rotate-video/ to turn it, then run the AVI to MPG conversion. Trimming first is faster than re-encoding the whole AVI just to drop unused footage.
