Panasonic UB820/UB9000 4K UHD Blu-ray player

[blue348]

I stopped updating the OLED and Denon awhile back (if there are even any updates).

B7: 06.05.03
920: 3600-3048-3095

The UB820 is running the latest, 1.76.

Yes. The problem isn't the output resolution, it's the player. It's just plain borked at properly deinterlacing 480i material, doesn't matter whether it's piped out at 480p, 720, 1080, 4K (note there's no source direct function so you can't output the 480i unmolested. I did have the brainwave of trying 1080i to try and preserve the original interlacing but nope, it's still doing it's crappy processing first and then applying the 1080i deinterlacing).

The way I detailed it in my original reply, isolates it down to specifically FEL DV discs on the 820 to LG OLEDS as confirmed by other people on another forum. Seems like a firmware issue with either the 820 or LG. There is a work around by changing the 820's 24p auto setting to off so it outputs at 60p. That will play a full feature without dropouts in DV. For some reason, the issue only occurs with the 820 outputting at 24p to LG OLED with FEL discs.

But turning off 24p (at least from my understanding) would downgrade the color space from 12 bit to 8 bit. Meaning, you aren't really watching Dolby Vision content the way it should be.

Is this the same method that can be applied to all other 4K players, such as LG? So we can compare if the 4K TV upscales better or if the 4K player upscales better by switching the player to 1080p mode and flipping back to 4K UHD using a standard BD?

I'm not sure if the LG player has something like a 'source direct' mode where it just passes thru the native resolution of the disc to your display. But even if it doesn't, yes, you can switch back and forth between 1080p and 4K on the player to see if the player or display upscales 1080p better. I would recommend doing controlled little A/B experiments with various scenes on different content looking to see which excels and I also like looking at certain test patterns (Spears and Munsil and AVS I use). I also like look at some of the chroma and luma patterns to see how they do on 1080p output such as when I looked at the Panasonic 420 and Oppo 103D. But if you're only using one player, it doesn't matter as much assuming that's the only one you're going to use. The Oppo basically has perfect 1080p output and paired with my Radiance Pro for upscaling, it's best option in my set-up.

I'd like to repeat what I said before about Panny, but with pictures this time

One picture is worth a thousand words, isn't it?

Using S&M disk:

[1] 24fps sourced material is very good:

and not a single pixel is cropped

Thus, almost all movies and some shows will play well.

[2] 60i sourced material is very bad [Ship test pattern]

Thus, many shows and cartoons will play horribly (and some movies that are reprocessed as 60i).

Addition:
output set to 2160p, YCbCr 4:4:4

Recently got the UB9000. Watching a Dolby Vision title (Arrow's "Flash Gordon"), I noticed that the special features, which are 1080p REC709 SDR, are being output as Dolby Vision 12-bit REC2020, just like the main feature. I also have an Oppo 203 and it outputs all content in its native form. Is there any way to change this on the 9000?

I believe both the 820 and 9000 just do that if they’re in DV mode. No option.

So once the player detects a Dolby Vision disc it stays "locked" in Dolby Vision mode, so to speak, until you eject the disc?

Here's what you do. If you're going to watch special features on a disc where the movie itself is in Dolby Vision, is to turn off Dolby Vision in the player's menu when you're watching the special features.

More or less. Unless you feel like disabling it like the above poster says.

I know, I checked the patterns years ago. They seem fine. But in actual playback of 480i - film based or otherwise - it's visibly 'off' to me. So I'll continue avoiding DVD playback on it like the proverbial plague.

The patterns for the film based material are more than fine: they are close to ideal. They are better than Toshiba XA2. But there is no question that XA2 produces better picture.
Test patterns are not everything...

How are you able to watch 480i, btw? Your player is Region 1?

A head-scratching "feature" by Panasonic. Makes no sense, frankly. I wonder why they decided in favor of this, unless it is a glitch that they never bothered to fix.

Do you recommend 24hz output for film based DVDs on the Toshiba or should I just stick to 1080/60?

It depends on TV, you have to test it. For 60Hz TVs it should not matter. But it may/will for 120Hz ones.

But in general, Toshiba forces 24Hz on all material if you select this option. Which is not good for menus and 60i sourced extras.

Addition: and, of course, Pioneer Kuro (72Hz) will benefit from 24Hz mode too.

I would update both the OLED and Denon if I were you (if there are updates of course). Updates on firmware seem to solve a lot of issues that come up. AV receivers especially need their firmware updated when they can be!

Does region hack still work after update?

[Telemachus]

I am on the newest Panny firmware and just did the remote hack last night
