Quote from: attila on April 01, 2020, 07:01:05 AM- if I cut the .mkv again with "Opus Encoder": will the sound be reencoded or will it be cut?
QuoteThat is will I loose quality everytime I recut it or only one time?
Quote- is there a way to keep LPCM audio format?
Quote from: attila on April 02, 2020, 05:45:19 AMWhich audio codec do you suggest? (from a compatibility point of view)
QuoteWhat about if I select a lossy codec at first encoding, then "copy" after subsequent encodings: will it be reencoded?
QuoteDoes it have any importance if I use mpeg as output format with AC3 audio if I select a lossy audio format? (does mpeg have any advantage/disadvantage compared to mkv?)
Quote from: eumagga0x2a on April 02, 2020, 09:25:34 AMFrom the compatibility point of view, the video should be H.264 (deinterlaced prior to re-encoding!) and audio AAC.
Quote"Copy" does not re-encode, but it may trim the ends of stream as well as at cutpoints.
QuoteMPEG (MPEG-2, I hope) is a legacy codec (necessary when you would like to make a video DVD), mkv is a container to hold all kinds of multimedia stuff. So the question should be, what are you going to do with the final result? What is the target device?If you want to make a DVD, MPEG-2 + AC3 is fine, but the container must be MPEG-PS, not MKV.If you don't want to make a DVD, MPEG-2 is a bad choice. I hope, you still have the original file to convert the video to H.264 or, depending on your target device, HEVC.

QuoteQuote"Copy" does not re-encode, but it may trim the ends of stream as well as at cutpoints.Audio streams have also such entities as keyframes in videos?
QuoteTarget devices are mostly computers and "smart" TVs.
QuoteIf the video stream is copied and audio is kept lossless: does it have any importance whether I reencode them now or sometime in the future when mpeg2 is not working anymore?
QuoteSo currently I think the easiest and fastest choice for me is to keep mpeg2 video, convert sound to AAC (lav?) and save it in MKV container.
