Saturday Night Fever 4K disc – major problems

Saturday Night Fever Issues
I just scanned through the new 4K disc of Saturday Night Fever. I thought it might be a DVD by mistake! The poor image contrast, color and clarity were on top of on a crippled Dolby HD 5.1 track and the worst menu image ever.

My first reaction was to try out the included BR with the same Dolby 5.1 HD track. The result…much better. The contrast, color and clarity were excellent. The room was filled with the rich surround track I remembered.

Next I spot checked the bit rate and here is really bad news!

For the opening credits the 4K disc ranges from 11 to 26 Mbps. The BR’s same credit sequence clocks at 30 to 36 Mbps!

The 4K starts a more standard 4K bit rate after the credits at 03:42, but the sound never achieves the fidelity of the BR.

Later in the 4K film, I found the scene running from 6:30 to 6:50 hovering around 20 Mbps, while the end credit sequence ranges from 11 to 21 on 4K and 25 to 35 Mbps on BR!

SNF takes the prize for my worst 4K disc and is not watchable when a BR version is available.

Paramount needs to offer a corrected disc or take responsibility and authorize refunds.

I don't have my 4K disc yet, but apparently Ron Epstein disagrees with your assessment of this 4K disc. Not surprisingly, I kind of expected this 4K disc to be a flashpoint for controversy and discussion, especially since it's a Paramount title.

The bit rates registered on my Oppo show what is there to work with.
4K usually floats in the 40 to 90 Mbps range, while this disc has long passages in the low end BR range of 11 to 20 bits. The BR version doubles those numbers for the same sequences. Has Ron checked the Blue to compare quality?
Also the menu looks like several DVD screenshots were captured for a bootleg effect, while the BR menu looks professional!

I didn't measure bitrates so your findings on that front are more revealing than mine.

However, I noticed an uptick in image quality/detail of the 4k over the Blu-ray, noting however that there is less grain evident which leads me to believe there was some removal done.

There's always the possbility that Indy just got a bad disc? I'd just return it and ask for a new 4K set...if it too looks as bad as you say go for the refund!! But at least this way, you'll know for sure, right?

I rarely stray from this forum to be able to read reviews elsewhere, but out of concern for what is being reported here, I went to see if I could find other reviews of this release.



This review on YouTube pretty much is aligned with my findings in that there is a better grain structure and more detail in the 4k release, though encoding has been criticized.

I would highly doubt that Indy Guy got a bad disc.

That's doable, but if someone else could confirm the bit rate on the opening credits it would confirm if the problem is a single copy or an encoding error. The first 3:15 minutes range between 11 and 20 Mbps. The standard BR in the same box doubles that rate.

Bit rates between UHD and BD can’t be directly compared because each format uses a different compression codec - the one used on BD is less efficient and therefore needs a higher bitrate to achieve the same result. It’s an apples to oranges comparison.

Oh Wow! Now THAT is interesting.

Since you’ve looked at comments elsewhere, I’ll note that a prominent member at another site says the HDR10 is a disaster but the Dolby Vision is much better. That could account for the different reactions here.

I knew this title would be a problem. I vividly remember seeing it at the drive-in, and even in it's original release, the image varied. It was never a pretty film. Some scenes were very grainy, while others were crystal clear. That has to be difficult to transfer.

Sony or Warner could have done it.

After the major disappointment of the 4K, I watched the BR and everything was fine.
Also, I have no other 4K's that dip into an 11 to 20 Mbps rate except on blank screens.

May I ask whether you're running Dolby Vision or HDR10? Robert's post above suggests there may be an issue with HDR10.

Reading the review on the other site, it sounds like this may be an improperly authored Dolby Vision FEL title.

I use a Lumagen Radiance Pro which adjusts the input to match my projectors capability. The projector alone does not have direct Dolby Vision capability, but the Lumagen delivers a perfectly adjusted signal for almost all 4K input.

Guess this proves 4k not for every film --

Yes, but the Lumagen can only process what it's being fed, right? If you're projector is not Dolby Vision capable, then it's (by necessity) feeding an HDR10 signal to the Lumagen. If there IS an issue with HDR10 (and I'm only saying if there is as I really have no idea at this point) then your Lumagen must be working from that flawed signal in the first place. Right?

The Lumagen receives direct output from an Oppo 203. It adjusts the signal to what the projector can handle irregardless of the disc encoding, so the Lumagen has done all the processing before sending a proper signal to the projector where the processing is in override mode.
This creates 4K images that require little or no adjustment for a great looking picture.
Has anyone else confirmed the sub standard bit rates during the opening credits and "Staying Alive" song?

Wow, I took a quick peak at mine the other day and just watched a few minutes and thought it looked very good and very detailed (large projection screen), but did not compare it to my bluray.
