There is no stream-copy switch on this page. A few pairs copy a compatible video stream into the MKV container without re-encoding it, MKV to MP4 among them, which is quick and loses no quality. Most pairs re-encode the video. DivX مینځپانګه ده MPEG-4 برخه 2 ویډیو، معمولا په AVI، سره MP3 یا AC-3 غږيز د هغې سره سره راوستل. MKV دی codec-agnostic: H.264، HEVC، VP9 او AV1 ویډیو په خوښۍ سره د AAC، FLAC، Opus، DTS یا Dolby غږ په ورته فایل کې سره ناست.
ایا MKV یو کانټینر یا کوډ دی، او ایا دا بدلیږي چې زه بیرته راځم؟

دا بدلونونه څه د محصول دوتنې څخه تمه. د دې بدلون نومونه يو اړخ د يو encoding پرځای د يو wrapper، نو څه بېرته راځي دا ده چې په هر ډول کانټينر کې bitstream دا غوره fits - په عمومي ډول MP4 يا MKV. د پراختيا د کانټينر انعکاس؛ د codec دی څه په حقيقت کې د دوتنې د اندازې او چېرته چې دا به لوبې.
به ډېر-پټلۍ غږيزه بڼول DivX ته MKV ژوندی پاتې شي؟

Usually not. Most conversions keep one audio track, the one with the most channels (normally the main mix), re-encoded for the MKV container, so commentary and alternate-language tracks are dropped. AVI, WMV, MPEG, FLV, VOB and M4V to MKV keep every track, and so does MP4 to MOV. To keep a different track, remux the DivX with that track first (VLC or ffmpeg can do this), then convert it. MKV Matroska ده، د يو خلاص کانټينر په 2002 کې د جوړ شوي دي سره د کومو د جواز محدوديتونه او نه د کومو چې دا کولای شي د ساتلو د لوړوالي.
On some pairs. MP4 to MOV keeps every text subtitle track. AVI, WMV, MPEG, FLV, VOB and M4V to MKV keep every subtitle track: text subtitles are copied or converted to SRT, and picture-based subtitles such as DVD or Blu-ray ones are copied as they are. MP4, MOV and WebM to MKV keep only the first subtitle track (as ASS), and MP4 to WebM keeps the first one as WebVTT. Other pairs, including MKV to MP4 or MOV and WebM to MP4, drop subtitle tracks, and the converter does not burn them into the picture. Subtitles that are already burned in stay, because they are part of the video frames.
It depends on the MKV 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. MKV د انتخاب د آرشیف کانټينر ځکه چې دا د يوې دوتنې په بې نه محدود غږيزو ترانسپورت، نرم subtitles، فصل markers او پوښ هنر ساتي. MKV لري نږدې هیڅ اصلي هارډویر ملاتړ - فونونه، برېښناليکونه او تلویزیونونه معمولا د VLC يا د remux ته اړتيا لري مخکې له دې چې دوی به دا ولوبوي.
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 as it is. When the video is re-encoded, the HDR10 mastering metadata is dropped and Dolby Vision or HDR10+ data is not kept, and with a Quality, Resolution or Frame Rate setting some pairs also reduce the video to 8-bit colour, so an HDR DivX can look washed out in the MKV.
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 DivX 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.
