So this is totally something that has sort of fascinated me for a bit and I was wondering if anyone has ever managed to get working?

So apparently, certain audio codecs have the compatibility of including two separate LFE channels.

What's more, there's clearly documentation of it being coded into FFMPEG as part of the added support for 22.2 mixes—as insane as that sounds.

Now whilst I understand that there is the whole argument about whether or not this is something that'd even be worth the effort given low frequencies aren't particularly "directional" so-to-speak, I still at least like the prospect of its existence in a codec since it technically opens the door to properly supporting stuff like Dolby "Baby Boom" stuff which had dual LFEs.

Obviously, the opportunity of preserving something like that is practically nonexistent here, but I'm more curious about whether or not it can even work more than anything else at this point.

So I was spending a fair chunk of my afternoon testing different channel layout combos in FFMPEG to see if I can get it working, but for whatever reason, I can't seem to get it working whatsoever.

Maybe I'm doing something wrong with my code, but for some reason every time I try introducing the LFE2 in AAC, I get an error saying "Channel 3 cannot be referenced twice", so I assume the software's interpreting LFE2 as LFE still or something? I even tried trying to do a test creation of a 22.2 track—since it's the only standard channel layout that includes this mysterious channel—and not even that works.

I don't know. I don't suppose anyone else is willing to give this a shot on their end for experimentality's sake?

A hidden gem of 70s political thriller on conspiracy theories and paranoia. Shot by Gordon Willis, the same cinematographer who shot The Godfather two years prior. Highly recommended.

A shame that Criterion filtered away all the bass: Everything below ~70Hz is gone. Moshrom posted an excellent clip as usual: https://blah-ray.blogspot.com/2021/08/th...-1974.html

I've synced the unfiltered track from AMZN WEB-DL to the Criterion BD. Waveform and spectrogram match what Blah-ray showed. In particular, notice how the low frequencies are absent on the Criterion BD's spectrogram, but full of life on the WEB-DL.

Notes on the sync:

• The WEB-DL looks quite different from the Criterion BD, notably in color timing. I would guess it was encoded from an old DVD master.
  
• Frame wise, there are only two diverging points. The first is WEB-DL contains an extra frame (#129883).
  
• The second is a minor editing error on Criterion's part. During the epilogue, their frame #141582 is a duplicate of the next frame (#141583). The only difference is that it's not color-corrected and has a green tint that's not present from the next frame until the end of the sequence. Easily visualized here: https://slow.pics/c/F49FoV2L. This frame is absent on the WEB-DL. If you're interested, I've described this in more detail on BR.
  
• Again during the epilogue, the dialog is out of sync by > 1 second when the committee announced its findings. This is the case for the Criterion BD, AMZN WEB-DL, and apparently the recent Imprint BD as well. At first I thought the dialog may have been dubbed in post. But after applying a -1300ms delay, it was clear that the dialog matched lip movements. So this must be an error that has gone back for years. I've now fixed it.

Scooby-Doo! and the Witch's Ghost has an HD web-dl, but I'm not a huge fan of how it looks. 

Comparison

For the most part the DVD is progressive, but there was a small handful of frames that showed interlacing artifacts. I did my best to clean these up. I also applied a very fine layer of grain to give it a more natural look.

Video
1080p h265 HEVC

Audio
Dolby Digital 5.1 - R1 DVD

Chapter titles and subtitles taken from the DVD as well.

The credits indicate it was originally mixed in Dolby Stereo, and the only good source of that mix would be the VHS release. I don't have a way to rip VHS so if anyone does and can provide me the audio I'd greatly appreciate it.

Hi everyone. I'm looking to build a new PC to get myself set for editing in 4K.

My current PC build is getting on a bit now, I think about 9 years. i74770K, 32GB RAM, GTX770 4GB.

As I've been out of the loop on new PC stuff for a while I'm not sure what everyone is using these days. I've been watching some YT videos and there is a lot of conflicting information. Intel vs AMD, DDR5 or DDR5, etc.

I'll be using mostly Adobe Suite, Premiere, and AE.

I'm also going to need a new monitor since my current one is only 1080p. Used for colour correction and playback.

I'm not looking for a budget option, this thing will be with me for a while, so I don't want to cheap out on it. I also don't want to waste money on the latest parts just for a couple of percent performance increase.

Interested to hear what others are using and opinions on where is best to spend the money for our specific hobby. I'm not looking to make a gaming PC.

Cheers everyone.

Tough one here: getting interference on my S-Video in on my Diamond VC500 USB capture card..
The composite (RCA) in does NOT have the interference..
-Replaced cables, that didn't do it.
-Moved the card around to different ports, nothing changed.
-Tried turning off every device in my room.. nothing.
-Uninstalled/reinstalled the driver.. still not resolved.
-Tried 3 different capture programs.
-Even replaced the cap card w/ an identical brand new one.. same problem.
I don't get it. It worked a few months ago flawlessly in Win10 x64. I don't know whats changed??

Note: its not RGB aura lights (they're off just like they were 6 months ago when I last capped. Its not the wall outlet either, tried that. Nor the lights in the room.. same lights as last time.

Hi there! As someone who is all for the preservation of theatrical releases, original audio mixes, etc. this seems like a good place to be.

PS: I am a bit confused as to why there is another forum with a very similar domain name.

Greetings every one,
A humble request regarding Thelma & Louise [1991] - https://www.imdb.com/title/tt0103074/
https://www.lddb.com/laserdisc/03923/ML102410/

Looking the audio(s) specific to this LD linked above, can be unsynced or synced to BD etc.

Regards

Absolute beast audio for the movie.

Synced to UHD.
Also managed to sync the AUS BD to UHD (FYI even the AUS was oos when compared to UHD).

PM for links if needed.
