Extracting only 1 stream from Blu ray disc ?

[hdtvjeff]

Quick question,

How if possible can I select the main title to be extracted to a hard drive folder, in original M2TS format, not copy the entire disc and not in MKV format

Is that possible?

Thank You !

Not really - the Backup feature is "whole disk".

Remember that a "main title" can be more than one m2ts file. Watching MakeMKV rip Rogue One to MKV files earlier this month, the main feature was pulled together from MANY m2ts files.

Thank you for the answer !

Quality wise and bitrate wise, is the MakeMKV mkv output virtually indistinguishable from an original M2TS ?

The streams inside the m2ts file are copied to the MKV file. Video is never recoded within MakeMKV; so the video should be the same.

You can optionally convert some audio streams, but that is not done by default.

So why might MKV file size be lower?

Is the bitrate staying untouched too?

Thanks !

Bitrate should not change. If you do not select all audio tracks, or all subtitle tracks, or a combination of those, the file can be smaller.

Personally, I rip all audio tracks, regardless of language, and all subtitle tracks, so generally the size is without a few megabytes between them. And the MKV can be bigger, if the title you're ripping is constructed from multiple m2ts files.
