ווי קען איך איבער־קאָדעירן M4V צו MP4 אָן אָנצולײגן די ווידעאָ־קװאַליטעט?
+
Upload your M4V 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 MP4 output gets a codec its container supports: H.264 for MP4, MOV and MKV, VP9 for WebM. א סטריקטורעלע M4V איז אַ MP4 — H.264 אָדער HEVC מיט AAC — מיט אַ אָלטערנאַטיוו Apple FairPlay DRM און iTunes קאַפּיטל מעטאַדאַטע. די גאנצע סדרה איז באזירט אויף די 1960ער יארן, און די גאנצע סעריע איז באזירט אויף די 1970ער יארן, מיט די 1990ער און 2000ער.
װאָס איז דער סיבה אַז מײַן טעקע M4V קען ניט ווערן איבערגעזעצט צו MP4?
It depends on the MP4 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. MP4 איז א ISO/IEC 14496-14 סטאנדאַרד, סטענדאַרדיזירט אין 2001 און באזירט אויף די זעלבע קוויטשט קעסטל אויסלייג ווי MOV.
װעט מײַן אודיו־פֿאַרב איבערלעבן די איבערזעצונג פֿון M4V צו MP4?
+
Yes, the main audio track comes through, re-encoded to a codec the MP4 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.
קען איך בלײַבן מיט דער אָריגינעלער ראָם־רײט װען איך װײַז אױס M4V צו MP4?
+
Yes. The frame rate is kept unless you change it: a 24 fps M4V stays 24 fps in the MP4. 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.
How much will the file size change going from M4V to MP4?
+
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 M4V 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.
װעט די טעקע MP4 אױסשפּילן אױף iPhone, Android און סאָרטי־טעלעװיזיעס?
+
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.

ווי לאַנג װעט עס נעמען צו איבערװײַזן אַ 1־שעה־װײַטע M4V װידעאָ צו MP4?
+
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 M4V can look washed out.
איז מײַן M4V װידעאָ פּריוואַט בשעת דער איבערזעצונג צו MP4?
+
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 MP4 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 M4V first, or /rotate-video/ to turn it, then run the M4V to MP4 conversion. Trimming first is faster than re-encoding the whole M4V just to drop unused footage.
