Why 24fps is not enough for HDR movies

[proyal]

Thanks, but I prefer to use a short test clip that I can go over again and again on every TV One that can reveal potential problems in picture processing / shadow detailing and so on. I'm still looking for the perfect match.

The problem with using a Blu-ray movie is that it is encoded in H.264 / AVC on the disc so in order to do a HEVC version you are re-encoding an already lossy version, which is not optimal for testing purposes (other than confirmed that the TV can decode the file and bitrate obviously).

These ones may not be re-encoded from h264 since they come from digital distribution {WEB-DL} :

Many file sizes to chose from too.

On bluray disk, yes, it is re-encoded indeed. You are right.

Thanks, I'll look into it.

I actually tried to rip some of the test clips that TV manufacturers use (and supply to reviewers on USB hard drives or a test player), but most of the time the devices are locked. I also noticed that a lot of the test clips used on 4K TVs at trade shows are actually high-bitrate mpeg2 videos

LG LF630V in 2015 comes with HEVC but no 3D.

Any other 1080p models from LG in 2015 ?

Samsung considers Full HD trash so their full HD lineup will be very bad technologically this year compared to 2014 models.

No HEVC in Samsung J6300/J6200/J5500

Better hope Sony uses HEVC on their 1080p and they get great results in tests.

I can't see any LG higher than 6 series either. So only cheap crap models on market this year.

The 8 and 7 series Full HD are missing from LG. Can you confirm this ?

Can you confirm if Sony Android TV will come with HEVC on 1080p models ?

[Rasmus Larsen]

Sony just told us that the Full HD TVs with Android TV do not support HEVC or VP9. This is unfortunate, but I'm still not 100% convinced. Still digging a little.

Philips' Full HD TVs with Android TV support HEVC (but not VP9)

The 8 and 7 series Full HD are missing from LG. Can you confirm this ?

Yes true. I can confirm that there are no 7 or 8 series Full HD TVs. Only 6, 5 and 4 series will use HEVC.

A full overview of LG's 2015 TVs will come online here on FlatpanelsHD very soon.

Regarding Philips (TP vision).

This article : http://www.hdtvtest.co.uk/news/philips- ... ent-493156 states that :

Delving into the UK-bound ranges, the majority that will be arriving during the first half of 2015 will be full HD 1080p models, with the higher-end ones getting the aforementioned double-sided QWERTY remote, 100Hz native 10-bit LCD panel, active 3D capabilities, 2- or 3-side Ambilight (which this year is boosted by the addition of new presets for music and gaming), and higher Picture Motion Rate (PMR) specification.

The higher ones meaning the 6500 full hd series.

100Hz native with true 10-bit LCD panel is fantastic if true and still at 1080p price levels.

Any idea ?

[Rasmus Larsen]

10-bit Full HD panels, hmm well. I will need to have that confirmed by Philips before I believe that Higher-end models could also mean the UHD models, no? Philips has a HDR capable TV planned for the third or fourth quarter of 2015 and that will surely use a 10-bit panel.

Normally 99% of all IPS were 6 bit + FCR (frame rate control) and VA were true 8 bit with only some expensive IPS being true 8 bit like the VA panels.

So as you say, only high end ultra HD are true 10 bit panels. The 6500 with active 3D is most likely a 8 bit VA 60Hz panel just like the Sony.

There was some debate weather h265 can retain the same fine details /grain as h264.

Conclusion is that even the latest H265 is not able to preserve details in the video and that h264 is superior in terms of details.

http://forum.doom9.org/forumdisplay.php?f=81

How is x265 superior and useful on 4K if it lack details except for bandwidth ? It is not apparently.

So right now there is no problem buying a TV that lacks HEVC on 1080p it seems.

Any comment ?

[proyal]

Maybe in 2016 1080p will come with HEVC.

Any news if TVs can handle full bit-rate movies from USB ?
