Ya. FLV teu mibanda trek subtitle soft anu bisa digunakeun, ku kituna subtitle pikeun FLV kudu dibakar kana gambar atawa dikirimkeun minangka file sidecar nu béda. MKV mibanda subtitle minangka stream anu bisa dipilih, ku kituna sanggeus konversi anjeun bisa nyambungkeun trek SRT anu bisa diaktifkeun, dimatikan atawa dirobah gayana.

Pikeun sagala anu anjeun badé jaga, ya. FLV asalna ti generasi saméméhna alat video sarta parangkat lunak anu maca éta terus-terusan kaleungitan ti telepon, browser, jeung sistem operasi. Ngalikeun pilem kana MKV ayeuna, nalika masih aya dekoder bersih, nyaéta béda antara arsip anu anjeun tiasa buka dina sapuluh taun sareng anu henteu. Teu aya browser, telepon, atawa TV anu ayeuna bisa maénkeun FLV — sagala anu aya dina wadah ieu kudu dipindahkeun ka luar pikeun tetep bisa disaksikeun. MKV nyaéta arsip anu dipilih sabab éta nyimpen trek audio tanpa wates, subtitle soft, tanda bab sareng gambar cover dina hiji file.

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 FLV with that track first (VLC or ffmpeg can do this), then convert it. MKV nyaéta Matroska, hiji kontener terbuka anu dirancang dina taun 2002 tanpa watesan lisénsi sareng tanpa watesan kana naon anu tiasa disimpen.

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.

MKV nyaéta hiji-hijina wadah mainstream anu nyimpen lampiran berkas anu dipikahoyong (font TTF pikeun subs ASS, gambar sampul JPG, inserts PDF disalin ku fans). Ngaliwatan FLV ka MKV bakal ngaleupaskeun lampiran ieu lamun MKV henteu MKV — aliran dasarna dikonversi, tapi payload anu dilampirkeun tetep dina sumber. Pastikeun FLV salaku salinan cadangan upami anjeun gumantung kana fonta anu dilampirkeun.

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 henteu ngagaduhan dukungan hardware asli - telepon, browser, sareng TV biasana peryogi VLC atanapi remux sateuacan tiasa diunduh.

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 FLV 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 FLV 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.

The converter has no resolution cap of its own; the limit is the upload size allowed on your plan, and 4K, 8K and 60 fps files keep their resolution and frame rate unless you change them. MKV to MP4 or MOV with the default settings copies the video stream, which is quick at any resolution. Other pairs re-encode on CPU and the time grows with the pixel count, so a long 4K or 8K file takes much longer than the same length in 1080p.
