How to extract scenes from the 4K.. series video files?
Time

Hm, that’s interesting…do you have enough hard drive space? What options do you have checked?

Since I haven’t yet left for work, I opened up my 4K77 v1.4 in mkvtoolnix - if you just want the 35mm Dolby Surround track, here’s what it should look like (this is assuming you still want the chapter headings; unchecking the “3 entries” of “global tags” at the bottom shouldn’t cause any problems, but just to be safe I’d leave it checked:

Make sure you point your “Destination file” to the location you want that has plenty of free space (this file will most likely still be in the 55-65GB range even after most of the audio tracks are stripped), then click “Start multiplexing” and you should be fine. Just leave your computer alone while it works!

The primary use of tsmuxer is to either demux files (split an MKV/MP4/etc. into its elementary video, audio, and subtitle streams) or mux them into a Blu-Ray or AVCHD folder/ISO or .m2ts file - it can’t output a muxed MKV or MP4 or whatever.

The primary use of mkvtoolnix is to either take elementary streams and mux them into an MKV file, or to take an existing muxed file (MKV/MP4/etc.) and take out/rearrange/add audio or subtitle tracks, outputting an MKV file.

Basically, mkvtoolnix will give you an MKV file at the end that contains exactly the tracks you want, but tsmuxer can’t do that (you could make it give you an m2ts file or an authored Blu-Ray with no menu, though).

Here’s a good thread on the various audio mixes:

https://originaltrilogy.com/topic/Star-Wars-sound-mixes/id/15294

The mono mix was the last one prepared and has quite a few different sound effects, new lines of dialogue (the tractor beam line extension and “close the blast doors” which were put back in in 1997), alternate dialogue takes (all of Beru’s dialogue), etc. I like it for the differences (“Blast it, Biggs” sounds weird to me now), but the quality isn’t as good, obviously. It was restored from a videotaped recording (or two?) of a TV broadcast that used the mix; it’s never been officially released on home video.

Here’s hairy_hen’s thread about his 5.1 recreation of the 70mm Dolby Six-Track mix (which is the 5.1 mix included on 4K77 and Despecialized):

If LUTs are what you’re primarily interested in working with, I’d recommend first demuxing the video stream out of the MKV file before doing anything else with it. Grab tsmuxer (free), open the file using it, uncheck everything except the video stream (h264 for the 1080p and h265 for the 4K), select “demux” above the destination field, then choose where you want the file to go.

You’ll end up with a video-only stream that some programs might not be able to open, but most things that you can use to apply LUTs should play nicer with that than with a muxed MKV file.

You can also check one of the audio tracks if you want to end up with both the video stream and an audio track as two separate files in the end, which might be useful depending on what you want to do with it in the end.

Oh, okay, I thought you were asking about 4K video in general.

Um…which releases of the films do you have? The actual 4K MKV files, the 1080p MKV files, or the 1080p authored Blu-Ray files?

Windows Media Player is probably the worst possible choice for doing whatever it is you’re trying to do. These files all have multiple audio tracks, a good chunk of which are lossless DTS-HD MA files - those two things alone probably make Windows Media Player panic. Add in the fact that the 1080p versions are high-bitrate h264 and the 4K version is a whopping 80GB or so MKV file encoded in h265 and I’m surprised Windows Media Player actually plays them!

What exactly are you trying to do with the files? That might help narrow down your options. You’ll almost certainly have to strip out all but one audio track first, and to make sure you pick an audio track that will work well with whatever it is you’re trying to do (which might mean downloading a separate PCM track if the software you want to use doesn’t like DTS-HD MA or 5.1 tracks).

  1. Yes, the specs are the same.
  2. No, don’t downmix the 5.1, use the 2.0 track - the 5.1 is a specifically constructed upmix of multiple 2.0 and 5.1 tracks to recreate the 1977 70mm six-track mix as closely as possible and is not suitable for 2.0-channel downmixing. The 2.0 tracks are all authentic, direct-from-laserdisc stereo tracks.

New video format proposal

Yep yep. The only major drawback I see to the BR standard is the lack of 1080p25/720p25 support (requiring many UK shows like Doctor Who to release 1080i50 BRs, or slow down the video to 24fps), and I don’t even know if that’s a thing for UHD BR.

All the other issues you present are really non-issues - resolution? Upscale/downscale; your player or the TV itself will have to do that to display it anyway if it isn’t in your display’s native resolution. Aspect ratio? Letterboxing; the amount of bitrate wasted on black bars is negligible.
