Ta yaya zan sake encode MP4 zuwa HLS ba tare da rasa ingancin bidiyo ba?

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 HLS output gets a codec its container supports: H.264 for MP4, MOV and MKV, VP9 for WebM. A kusa da dukan MP4 a cikin daji ne H.264 bidiyo da AAC sauti; da kwandon kuma doka ke da HEVC, AV1 da VP9. A HLS stream is a.m3u8 manifest pointing at a staircase of H.264 or HEVC segments at several bitrates, so the player can switch quality mid-playback.

Wanne codec na bidiyo ne fitarwa HLS take amfani dashi?

It depends on the HLS 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. HLS shine Apple's HTTP Live Streaming - ba fayil ba amma playlist tare da fayil na ɓangarorin kafofin watsa labarun.

Shin za'a iya canza waƙoƙina na sauti daga MP4 zuwa HLS?

Yes, the main audio track comes through, re-encoded to a codec the HLS 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.

Menene lokacin da za'a yi wa canja bidiyo mai awa 1 zuwa MP4 zuwa HLS?

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.

Mene ne mafi girman ma'aunin rarraba da ake goyon baya ga MP4 zuwa HLS?

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 color, so a HDR MP4 can look washed out.

Shin MP4 bidiyo na na sirri ne yayin canjawa zuwa HLS?

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 HLS are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.

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.
