Nola birkodetu MPG MPEG(e)ra bideo-kalitatea galdu gabe?
+
Upload your MPG 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 MPEG output gets a codec its container supports: H.264 for MP4, MOV and MKV, VP9 for WebM. MPEG-1 edo MPEG-2 bideoa MP2 audioarekin; muxing-a eta GOP egitura.mpeg fitxategiaren berdinak dira. Bideoa MPEG-1 edo MPEG-2 da, MP2 edo AC-3 audioarekin, funtzio finkoko hardwareak dekodetzeko diseinatutako korronte batean multiplexatuta.
Bi formatu zaharren artean (MPG eta MPEG) 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. MPEG-2k H.264ren bitratea lau edo sei aldiz behar du irudi berberak grabatzeko, eta bere edukia sarritan interlaced da, pantaila modernoetan orrazia dirudiena.
Zein bideo-kodeke erabiltzen du MPEG irteerak?
+
It depends on the MPEG 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. MPEG-1 edo MPEG-2 bideo-formatu bat da, bideo-CD eta DVDak grabatzeko erabiltzen dena, eta bideo-fitxategien formatu estandarra da.
Nire audio-pistak iraungo du MPG-tik MPEG-ra bihurtzean?
+
Yes, the main audio track comes through, re-encoded to a codec the MPEG 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 MPG MPEG bihurtzean?
+
Yes. The frame rate is kept unless you change it: a 24 fps MPG stays 24 fps in the MPEG. 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 MPG(e)tik MPEG(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 MPG 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.
MPEG 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. MPEG programa korronteak dekodetzen dira literalki DVD erreproduzitzaile, set-top box eta broadcast kate guztiek, eta bit erroreak onartzen dituzte.
Zenbat denbora behar da ordubeteko MPG bideo bat MPEG 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 MPG eta MPEG 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 MPG can look washed out.
Nire MPG bideoa pribatua da MPEG bihurtzean?
+
Yes. Uploaded MPG files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted MPEG 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 MPG-(e)tik MPEG-(e)ra bihurtzean?
+
Not in the same step. Use /trim-video/ or /video-cutter/ to clip the MPG first, or /rotate-video/ to turn it, then run the MPG to MPEG conversion. Trimming first is faster than re-encoding the whole MPG just to drop unused footage.
Zergatik da lauso MPEG fitxategia MPG iturburuarekin alderatuta?
+
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. MPG DVDak sortzeko softwarearen luzapen bat da, kamera zaharrek eta broadcast ingest tresnek onartzen dutena, beraz, kanal horietan erabilgarria izaten jarraitzen du.
