MKV to MPEG Conversion FAQ
How do I re-encode MKV to MPEG without losing video quality?
+
Upload your MKV 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 MPEG output gets a codec its container supports: H.264 for MP4, MOV and MKV, VP9 for WebM. MKV is codec-agnostic: H.264, HEVC, VP9 and AV1 video sit happily beside AAC, FLAC, Opus, DTS or Dolby audio in the same file. The video is MPEG-1 or MPEG-2 with MP2 or AC-3 audio, multiplexed into a stream designed to be decoded by fixed-function hardware.
What happens to the subtitle tracks in my MKV file?
+
They are dropped. MPEG has no soft-subtitle stream to hold them, and the converter neither burns them into the picture nor exports them as a separate file. If you need them, extract the subtitles to an .srt file with a desktop tool such as ffmpeg or MKVToolNix before converting, and load that file alongside the MPEG in your player. MPEG-2 needs roughly four to six times the bitrate of H.264 for the same picture, and its content is frequently interlaced, which looks combed on modern displays.
Why would I convert MKV to an older format like MPEG?
+
Because a lot of hardware never learned anything newer and never will. DVD players, in-car head units, camcorder playback modes, industrial displays and plenty of broadcast ingest equipment accept MPEG and nothing else. The conversion is a deliberate step down in efficiency, bought in exchange for working on a device that has no other option. MPEG program streams are decoded by literally every DVD player, set-top box and broadcast chain ever built, and they tolerate bit errors gracefully.
Which video codec does the MPEG output use?
+
It depends on the MPEG 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. MPEG here means an MPEG-1 or MPEG-2 program stream, the format standardised for Video CD and then for DVD and broadcast television.
Will my audio track survive MKV to MPEG conversion?
+
Yes, the main audio track comes through, re-encoded to a codec the MPEG 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.
Can I keep the original framerate when converting MKV to MPEG?
+
Yes. The frame rate is kept unless you change it: a 24 fps MKV stays 24 fps in the MPEG. 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 MKV to MPEG?
+
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 MKV 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.
Will the MPEG file play on iPhone, Android, and Smart TVs?
+
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.
How long does converting a 1-hour MKV video to MPEG take?
+
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.
What is the maximum resolution supported for MKV to MPEG?
+
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 MKV can look washed out.
Is my MKV video private during conversion to MPEG?
+
Yes. Uploaded MKV files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted MPEG are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
Can I crop, trim, or rotate during the MKV to MPEG conversion?
+
Not in the same step. Use /trim-video/ or /video-cutter/ to clip the MKV first, or /rotate-video/ to turn it, then run the MKV to MPEG conversion. Trimming first is faster than re-encoding the whole MKV just to drop unused footage.
