Develop Bugs

Is [email protected] due to the software?

As Google announced at their event, the GN should film [email protected], but after seeing the many review which are available on the net, the conclusion is that the GN only films at 24fps.
Could this be fixed through software? It would be a huge lie, if Google mentioned 30fps, reality being something else.

i would also like to know that.. really dont like 24 fps

Is that why the videos seem so choppy ?

generally, most film is done at 24FPS which is the standard for NTSC. in the past, they would 'convert' films to 30FPS by "splitting" the A/B fields in the video in an attempt to give it a more fluid sort of feel. they originally did this for older tv sets though...
if you were watching such films on a newer TV for instance you could tell a video's been converted by seeing occasional weird doubling/lines appear in motion-filled areas. tv's/pc's though have software "filters" to hide this effect, at least the lines part.. but if you have good eyes you'll still see the occasional doubling(ghosting).
considering the compact size of the GN screen though, you should not see "jerkiness(choppiness)" unless it's some sort of hardware or software related issue.
[EDIT] although it would still be weird to do a full 1080P video and limit it to 24FPS even if you are just watching it on your phone. the whole 24FPS thing was from the DVD days.

This is normal spec of 1080p videos. If you had an HTPC you'd probably already be aware of this, as some videocard manufactures have a bug were it's not fully 24fps, or alternates causing you to see a shudder..

When filming at 1080p it is usually done at 30fps...

The FPS is usually capped in media_profiles.xml that you can find in the source on AOSP. That's where the quality settings and codecs used per setting is defined.

But why all the video looks like under-water

Film is 23.976 fps. If your video card is set to 24fps instead of 23.976, you'll get a stutter every 41.66 seconds.

The resolution, screen density & camer pixel of Z5 premium is untrue

Hello ? everybody and expertise,
I have install CPU X app, on my z5 premium then i got shocked whe i found out that my resolution is 1080 x 1920 pixels and screen density is 403 ppi aside from 803 ppi more over i found the camera pixel is 8 megapixel aside from 23 mp
Any idea about whats happening with our handset

The phone runs in FHD. The resolution is correct. It only runs UHD in media content, photos and videos. Have you ever saw a review of this phone? This is well know by now.

So you bought phone and you have no idea how its work, you didnt read any reviews, that mention how this 4k work on z5p, and now you registered on XDA, and made topic IN WRONG SECTION about it.
Also maybe you could read USER MANUAL how superior auto mod work on camera? Its nothing hard, its in that box that you get with your phone :]

The phone goes into 4k mode when you are looking at 4k content (so 4k pictures and video etc). There is no need for 4k when you are looking at normal apps as that would just kill your battery and give you no visual benefit whatsoever.
As for the camera by default it shoots in 8mp but if open up the camera app then click the gear icon and then click resolution you can choose what MP you want. I recommend 20mp for best overall quality.

maybe you should read some reviews or watch review videos on the phone before you buy a phone :/

Does the Z5 Premium Allow 4K When Using As A VR Cinema?

Hi guys, I'm considering buying the Z5P to use with a virtual reality HMD (head mounted display) due to it's 4K screen resolution. I'm primarily interested only in using it as a virtual screen (aka private screen, private IMAX) due to the presumed ability (on my part) to display 1080 lines to each eye when using a HMD.
However I'm reading that the Z5P only uses 4K during certain situations but that this can be up to developers to implement.
So I'm assuming using a Z5P in a HMD to get a 1080 line display to each eye is possible in theory but can someone please confirm it for me - and I mean a person who has done it and confirmed it's actually 1080 lines.
I have read a couple of threads about doing this and while they claim it's working I need more reassurance that they aren't seeing a lower resolution while still having a marked improvement due to the high DPI leading to much less "screen door effect".
Thanks!

diji1,
I'm interested in the Z5p for the same reasons and also have a ZU just like you. Hope someone can come along and answer this.

I think to be absolutely sure which I will happily test is to run an overlay script or app that can tell me if the VR apps or games I run is in fact in 4k. So I see there are overlay apps to determine the FPS of a game. It will be nice to know it there is something similar to determine the resolution of the app/game.
One test I did make is to take a screenshot of CMoar Cinema running a movie. The properties of the screenshot says its 4K (3840x2160). But perhaps you can analyse the screenshot file for yourself and determine whether the content is actually true 4k or not. I suggest analyse the interior parts of the cinema and not the actual movie (Force Awakens) shown on screen because I was playing a straight 1080p rip of my blu ray (I dont own any 4k blu rays). Hopefully the original screenshot file here can help you determine. Do let me know if you want me to upload screenshots of other games and apps. I will post this up on the other thread so we can discuss it a bit further given this is strictly a Q&A

Software (ease of use, features, etc)

When you hand your phone to granny to take a photo of you, can she get the job done? Rate this thread to express how you deem the Google Pixel's camera software. A higher rating indicates that the software is easy to use, fast, uncluttered, and inclusive of advanced features for when you need them.
Then, drop a comment if you have anything to add!

To sum up , This is a no compromise camera!

Coming from a Moto X '14 which had outstanding camera software I'm disappointed with the Pixel. You could do almost everything one handed on the MX14 from zooming in/out to taking a picture by touching the screen. Just yesterday I realized that I can't draw on pixel photos either. Hoping they add some usability features because the hardware is great.

The pics looks nice and crisp to me after I take them, low light detection still sucks like most other cameras. Colors are decent and hold up when I display them on a 4k monitor. I must say I like the speed, when I want to capture a moment it takes the pic right away. When I get close to an object it actually focuses where my buddy's Nexus 6 had issues with that. It seems like an improvement but there is still some features they can add. One handed operation would be nice.

When on home screen, Google assistant always detect "ok Google" even though I have turned it off in settings... Serious privacy concern!!... Does this really hear me fart!
Any solutions?
Even, I can see that the phone is never in sleep state and is always awake..
Any help?

I just got Google pixel yesterday.
I am trying to play 4k video on YouTube but for some reason there is no 4k option in quality.
what am I missing ?

pixel is fullHD bro, but it can capture 4k video

The pixel is not physically capable of displaying 4K video, so that's probably why you don't get that option.

iPhone 7 has only 720p display. It can still play 4k video.
Google just have to enable the 4k option for 1080p androids.

Is there any benefit to playing 4K video on a lower resolution display? Maybe you could perceive a difference in 4K video on a 1080p 20" or larger screen, but I don't that's the case on a phone. Just seems like a waste of bandwidth at that point for google and the end user.

I have a nexus 5x. I didn't realize that there are differences now. Before to just flash twrp su then you are done. I read there are 2 slot sorts something so twrp needs am IMG and zip.

no it can not. it can play downscaled video to 720p but you would get no benefit over watching the original 720p video.

Question 4k video worth it over 1080p?

I have been doing some video recordings today and noticed how large the 4k 60fps videos are (about twice as larger as 1080p 60fps recordings).
So I went ahead and did some 1080p recording to compare 4k and 1080p on my 4k LG CX TV.
Tbh, I didn't notice much of a difference.
So I am really wondering if 4k is even worth it considering its file size?

It mostly just depends on the camera used. I guess you used your phone to record. right? Most phones can't do 4K properly, it's just a feature they advertise. If to you 1080p looks fine, I don't see why you would bother with 4K60. Or maybe just try 4K30, in some cases it does end up looking better than 4K60.

i mean twice the size for 4X the resolution is worth it
you need to take into account the finer details and edging in 4K which will show better results.
also most smart tvs including the CX have resolution scaling and other filters to make lower res content look better on 4K panels
also dont forget thats an Oled tv thats gonna look great with whatever you pump into it

Ye but if most TV's (or small screens like our smartphones, or any 1080p screen) won't really show a difference in quality, why even bother with the bigger file size. No one will realistically notice? :S

One advantage would be that you could theoretically crop or zoom the video and still retain acceptable quality on most resolutions on screens. Just like you said, it won't make a big difference on standard FHD displays however it would be noticeable when the video is cropped or zoomed.

i mean by that logic why watch 4k and get 4k tvs in first place. why have a higher res screen.
I mean why get the pro should have got the 1080p panel 6
Theres a lot of content 4K video will shine
even 4k video downsampled to 1080p retains better details than 1080p does.
Sure on a phone screen you wont see the difference but on a tv thats 55inch or higher the gap is noticeably wider its a major difference.
There will be parts you notice also more so. take into the account if you want to focus on specific parts of a video or edit / crop edit
also your content is future proofed
open all the images in seperate tabs to see full resolution.
the latter 2 are 50% res of the original screencaps you can easily see the details are maintained scaled down

Real 4k movie content does look surely better on my 4k TV compared to a 1080p TV / content.
But that is real 4k movie material and not google pixel 6 pro 4k video content.
Are your screencaps from recordings done with the google pixel 6 pro?
Because I am talking only about the P6P recordings, not about anything recorder with smth else.

no they were not but the point still stands it was just a prime example
regardless i literally did test videos of still objects in my spare room with text from a distance.
in poor lighting conditions its literally dark and the bulbs ****
literally even look at the portrait still in gallery before you even play the video you could see the text on objects was actually legible and also sharper
if you fail to even notice the difference between 1080 and 4k on your tv you may need your eyes checked.
dont forget theres literally rated seating distances for screen sizes, distant seated and also resolurion of display
the closer you are the better the fine details you see
did you stand up and look or did you sit down and look so you basically looking at like a 20inch display
Sounds like you putting the LG CX to waste
it was the exaxt same situation with people when hd 720p and 1080p came out they coudnt tell difference from sd
also people who think FHD and 4K dont make a difference are the type of people who think you can see above 60fps.
One of these is 4k downscaled the other is 1080p downscaled both also limited to poor lighting conditions

Okay, then again: This is specific to the google pixel 6 pro.
Yes there is a difference between 4k and 1080p.
Yes there is a difference between 30hz,60hz,120hz.
But it also depends on the source equipment and how it is recorded.
I can use a **** camera to record a video in 4k but it won't look any better than 1080p due the camera being so bad. And this is exactly why I am asking this in regards to the google pixel 6 pro.
How good is the camera in videos really and how big is the difference with it in 4k vs 1080p.
Thanks, I know how to setup my TV. And due to my job I have to test my eyes every year.. still getting highest results :>
But if you can see a difference in the thumbnail of your image gallery, then the placebo is really strong with you.

Most people who cannot notice a difference either have reduced vision or use a small monitor. I dare everyone that can't make out a difference between 1080p and 4k source material to use a Monitor 40" or bigger. On my LG CX (48") that I use as a monitor the difference is night and day.
It should be noted, though, that the difference is rather minor when video footage has been shot by phones - their sensors are just too small to make out the minute differences, plus they can't take in enough light. If you compare professional video material shot by expensive dedicated gear in 1080p vs 2160p, the difference is HUGE, whilst smartphone camera footage isn't that "obvious".

At the end of the day it's what works for a given person. If 1080p video works then that's a great option, if 4k works then that's a great option.
If the 4k video is really only twice the size then it's because they're being more aggressive in compression. There's no magic bullet to squeeze 4x the data into 2x the space other than throwing data out.
Tangentially related - GoPro's 8/9 and probably 10 set (i.e. limit) the recorded video to 100mbs for higher resolutions. Ergo you get higher quality (less compression) with 4k24 versus 4k30 versus 4k60 because they're all recorded at the same bit rate.
The P6P may have throughput issues that limits just how fast they can write data that results in higher compression in order to reduce the file size at higher resolutions. Or it could be design choice to reduce file use since the most common ones are likely the 128gb versions.
In this case, specifically with the P6P's, the actual end result is that 1080P might be nearly as good as 4K if they're cranking the compression up and loosing the details that are the point of recording in 4k. So bottom line the OP could have a pretty solid case.
I should get mine tomorrow and the holiday coming up should make for some interesting testing.

For me, the question is do you need 60 FPS over 30 FPS? I do 4K because I want the highest resolution I can get but I do 30 FPS because I don't need that smooth look.

That's interesting that the bitrates are on the lower, half the bitrate for 4K30 for example compared to any GP in the last few years. Is this user adjustable is a question.
I'm getting the P6P 512 with the hope that I can ditch the GP's I usually carry. I record VLOG footage during my ultra runs and I carry a phone with me regardless. One less device and its accessories to deal with would be great.
I have a selection of video recorded with my GP 8 and 9's, I can run the same run/route in the same resolution and do an apples to apples comparison of quality. It'll be interesting if nothing else to compare the stabilization quality of each. Hmm, I think I can probably mount both the phone and a GP to the same stick and get direct side by side as well. The wheels are spinning now on how best to compare the final product of each for my needs.

could be a heavier encoding profile than standard go pros that and action cams in general usually have a large amount of motion so bitrate is needed to compensate and gopros are generally used professionally so editing etc needs that kind of headroom
my akaso v50x uses the same bitrate roughly at 4k30 as the pixel but is perfectly fine in daytime except its cheapness shows in low light performance
