Is it right for a three hour stereo DTS-HD MA track to be reduced from 1.9 GB to 250 MB when converting to FLAC? Is it really still the same quality? It's an old movie, Judgement at Nuremberg (Kino). I never converted any of my movies to FLAC until yesterday. Seems odd that there would be so much filler in the track.

FLAC is much more efficient then DTS-HD, plus it doesn't have the embedded DTS stream which at full bitrate can take up half of that 1.9GB by itself

I think its basically that DTS-MA is very bloated

Then the program fre:ac isn't messing up the conversion. Okay. Embedded DTS stream? I thought the DTS core was part of the same Master Audio stream. That when a device can't play MA, the codec simply tells it to cut off all the information above DTS core. Are you saying the core audio is redundant?

The core is the older DCA codec (full bitrate) and the extra information is used to reconstruct the lossy core into a lossless audio track

Like Dolby Vision layer on top of the HDR10 base on discs. Kind of what I thought at another time. So because it has to max out the DTS core bitrate consistently there is often more than needed. Okay, now I get what stwd4nder2 meant.

the filesize difference feels right. If the DTS-MA is a 5.1 (or 6.1 or 7.1) mix, you can replicate that in a lossless FLAC and save on the space. Some FLAC decoders might struggle a bit representing the discrete channels though

You also have to take into account the content of the audio track, a relatively inactive track will compress to a greater ratio than a busier, more active one

dumb Q but anyone begun tackling Babylon? I wouldn't change a thing, but I can understand how a few editors might want to tweak a tad here or there. Its divisive, but I loved it

Yay! I recently received a HD-DVD&BluRay Kombo internal drive! Now I am able to check out HD-DVDs on my PC! Sadly no recent Software Player to be found that still supports them playing.

That’s great MrBrown

Sadly all my HD-DVDs are all at another Place stored, I only have the 5 Disc Blade Runner HD-DVD Set at hand...

Pretty sure you can rip them with makemkv

I do not use makemkv for ripping. I avoid that shady tool, as I do not trust it at all. I know I can rip stuff now, but I want to play it on my screen without needing to rip it ahead.

Hope you can work something out MrBrown, it doesn't look like there is much software out there that can play HD-DVD, and any older software may have compatibility issues with newer versions of Windows

PowerDVD 7 (and PowerDVD 8 Ultra with some hack) were capable of.. I ordered a PowerDVD7 CD with key at ebay.. i try it.. its worth a try. Because I want to see the menus.. and not just be relying on ripping

Damn.. PowerDVD 7 would work with HD-DVD. But not on my win 10... So far.

Noticed fre:ac reduces my 24-bit DTS-HD movies to 16-bit when converting to FLAC. Is that normal? Is it fine?

just use ffmpeg

Never figured that out. Too complicated. Would rather just keep 24-bit in DTS-HD then.
