Nola erauzten ditut M4V bideo bateko fotogramak BMP irudi gisa?
+
Upload the M4V and open the options. Frame Extraction has two modes: Single Frame saves one BMP from the second you enter (for example 1, 5 or 10.5), and All Frames saves every frame of the video as a BMP image. There is no every-Nth-frame or one-per-second mode.
Zein bereizmenarekin ateratzen da erauzitako BMP irudia?
+
M4V bideoaren bereizmen bera — 1080p iturburu batek 1920×1080 BMP fotograma sortzen ditu; 4K iturburu batek 3840×2160 BMP fotograma sortzen ditu. Aldatu tamaina erauzketa egin ondoren koadro txikiagoak behar badituzu.
Erautsi al dezaket M4V fitxategiko fotograma bakoitza BMP gisa?
+
Yes, with All Frames in the Frame Extraction option, but watch the count: one minute of 30 fps video gives 1,800 BMP images. For a single still, choose Single Frame and enter the second you want instead.
HDR footage is not tone-mapped: each frame is converted from the M4V as it is decoded, so a frame from an HDR M4V can look flat or washed out as a BMP. Standard (SDR) video keeps its colours.
Zenbat denbora behar da M4V-(e)tik BMP-(e)ra fotogramak ateratzeko?
+
It depends on the size and length of the file. Small documents and images are usually ready quickly. Long videos take the longest, because most video conversions re-encode every frame.
Erautsi al ditzaket M4V bideoko denbora-zigilu jakin batzuetako fotogramak?
+
One at a time. Single Frame takes one time in seconds (for example 83 for 1:23) and saves that frame as a BMP. There is no field for a list of times, so run the conversion again for each extra timestamp.
Nire M4V bideoa pribatua da fotogramak erauzteko?
+
Yes. Uploaded M4V files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted BMP are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
Zergatik dira lausoak nire ateratako BMP fotogramak?
+
Ia beti mugimendu lausotzea iturburutik M4V (kamera mugitzen ari zen fotograma hartzean). Saiatu eszena estatikoetatik denbora-zigiluak ateratzen, edo atera alboko hainbat fotograma eta aukeratu zorrotzena. Kanalizazioak ez du zorroztasuna sintetizatzen.
Tresna honek eszena-aldaketaren fotograma bat erauzten du?
+
No. The converter has no scene detection and no one-per-second mode: it saves either a single frame at the second you enter or every frame. For one image per scene, extract single frames at the times where the scenes change.
Erabili al ditzaket erauzitako BMP fotogramak merkataritzarako?
+
Bai, iturburu M4V edukia arautzen duen lizentziaren arabera. Formatu aldaketak ez du erreklamaziorik gehitzen — ez dugu ur-markarik gehitzen eta ez dugu erreklamaziorik egiten BMP irteeran.
BMP fitxategiek irudiak konprimitu gabeko bitmap formatuan gordetzen dituzte, eta ondorioz, fitxategi tamaina handiak baina kalitate perfektua lortzen dira.
