Also a bit of sarcasm mixed in, as well.... I sort of disagree with your statement, bitrate of a video file should produce better quality, than an audio file, but I like your use of "automagically" OK, so you told me what Ripbot uses to mux, but what is used to govern the bitrate of an encode ??? If not mkvmerge ??? Speaking of mkvmerge, there is a newer version of MKVToolNix now available, v25...and does Ripbot use the 32 or 64 bit versions ?? Is there a way to at least maintain original bitrates using Ripbot ?? Generally I just use CQ 20, and everything is smaller / lesser bitrate, an "X Copy" type option (as used with your audio settings) might be an idea. Oh, and another thing I need to mention, the majority of 4K 2160p HEVC movies also have True-HD audio. Even my brand new 2018 model LG 4K TV doesn't support that format, so I have to convert any THD audio to DTS-MA or DTS to maintain the 7.1 tracks, as I'm pretty sure Ripbot can't do that. (Correct me if I'm wrong) Maybe I should say that Ripbot can't convert THD to DTS, only ac3. (and again, correct me if I'm wrong), as we've had this conversation before.

However, most of the files I use, are .mkv, and that option isn't available...can you make that an option for .mkv's ??? Or do I have to convert them to .m2ts with tsmuxer ??? Please tell me you can add it ??? |

If you want to retain original quality/bitrate in mkv then why don't you just use mkvtoolnix?

An interesting statement, none the less. I am using mkvmerge a lot more than I use to, tho. But, using Ripbot has some features that I like to use for filtering, audio, etc. Oh, and yes, increasing bitrates...lol !!! So is that a no, about adding Copy Stream for .mkv's ?? And another question I asked last night was, what does Ripbot use that affects bitrates ? For example, today I re encoded a basic 2160p movie that had an original bitrate of 24.7Mb/s, but running it thru Ripbot at basic setting's, with MDGrain filter, and CQ 20, it was reduced to 3,540kb/s, and of course a huge reduction in file size...I am yet to check out the quality. |

If you remove randomness (noise) from picture then encoder can achieve much higher compression ratios. For example MDegrain2 can reduce average bitrate in CQ mode by up to 1.7x factor!

And can you please answer the question I asked in the previous post, about bitrate control ?? |

You are just reducing degradation effect during lossy compression. Keep in mind that picture quality will be still worse than original due to lossy nature of compression. It is something like copying VHS tapes (worse quality) to BETA tapes (better quality) or audio cassette type-I (iron oxide) to type-II (chrome).

Hint: if you encode to a higher bitrate without any filters, the resultant will will be lower quality. In special cases you can encode with filters and result in a higher visual quality, but very high bitrate sources are not those cases. This is just a case of confirmation bias. |

I find Degrain helpful as a basic way of making it perceptually better looking for my personal taste. |

Nah, the MKVToolNix works and the updates to MKVToolNix are generally minimal. FFMPEG same situation.
As for Codecs he is almost always on top of it. I was just trying to be cheeky. The only thing in RipBot as far as features that I've been looking for is better queue management. I know FFMPEG crashes sometimes but almost always doubling my Encoding Servers (ie slowing per thread FPS) seems to keep it from crashing as much when it comes up for some videos more than others. |
