[Q] Best Video Quality?

Which is better between the following two:
YouTube (HD, 10m)
or
YouTube (High, 10m)
Also explain so I can get a better understanding what the differences are.
Thank you

I was curious too so I took some footage, trying to capture the same footage every time (about 15-16 seconds each). Here are my results:
HD 1280x720, ~6000 kbps video, 17 fps, 95 kbps audio, 11.8 MB
High 720x480, ~3000 kbps video, 18 fps, 96 kbps audio, 6.05 MB
YouTube HD 1280x720, ~6000 kbps video, 18 fps, 101 kbps audio, 11.1 MB
YouTube High 720x480, ~3000 kbps video, 17 fps, 98 kbps audio, 6.12 MB
So it looks like high is 480p res and HD is 720p res, as expected. What I don't understand is why there are YouTube and non-YouTube versions of essentially the same thing. I watched each file back to back and couldn't find any noticeable difference in quality between YouTube and non-YouTube versions.

[Battery saver] custom auto brightness

OK, so I'm testing out custom auto brightness settings to share with everyone to help improve battery life, its definitely a wip and I need testers to help find the perfect balance of darkness vs being able to see the screen clearly
Auto brightness settings can be found in "settings>display>custom backlight settings>edit other levels" in many custom roms just make sure screen dim level is set to 1 and use custom is checked

OK, so far I have the following settings which seem OK though might be a little dark, please test and report back
Only change values in the "screen" column
5
7
10
13

135

(Last value is just to ensure max brightness in very strong light)

Good to see someone already started this thread. I have some settings I collected from xda and android forums that have been working well so far for my needs...

Reset Threshold: 400Lux
Sample Interval: 2sec
Screen Dim Level: 5
Allow Light Decrease : Yes

3000 3999 90
4000 5999 100

If anyone can tweak these and get better results by all means do share!

Hi, i just tried these values, and for me its way to dark. I think that the display of the galaxy looks realy bad, if the value is under 1/4 of max.

I think most slots should be raised by 5-10 for best visibility but I would suggest adding a slot or 2 at the beginning of it for best low light (mainly nighttime) settings

Did you try my values? I think its a little easier to tweak some different light levels just to your liking, also the only thing that really doesn't look all that great are dark backgrounds on the home screen and launcher background but by raising some of the brightness levels by 5 or so at a time, its easily correctable... this is mainly to be a baseline guide since the stock values are wayyy to high in most cases
Fyi, before doing this I considered 2.5 hours on extended battery good, now I easily get 3+ even 4 hours on screen time with overclocking (1344 MHz) and interactive governor

I get 4 hours easy. I agree its a bit dark but I have no idea on what to modify because I don't really understand how its set up. To the guys who tried it already can you post your modified values that might be brighter ?

Just try upping the values in the "screen" column by 5-10...even with increasing by 10 its still far lower than stock (stock setting has 50 as lowest value when even 15-25 should be plenty bright
To determine what level you are currently on look at the very top for filtered/raw values and see which level they fit between the first 2 columns (lower and upper)

Ok I tried metalspring way and this is what I have now :
Window Length: 10 seconds
Reset Threshold: 400Lux
Sample Interval: 10 seconds
Screen Dim Level: 10
Allow Light Decrease : Yes
Lower Upper Screen
0 199 20
200 399 25
400 599 35
600 799 45
800 999 55
1000 1249 65
1250 1499 75
1500 1999 85
2000 2999 95
3000 3999 105
4000 5999 115
6000 9999 125
10000 ∞ 255
Oh I also have the color calibrated from franco kernel app using the values suggested in app so I'm REALLY liking this now. No gradient banding or grain, looks sweeet.
updated: after todays field test I modified the values to allow for gradual dimming as much as possible. I will keep tweaking and posting results here.

Hi, how can I get gradual change like stock does? More values? Less? I hate the pop high/low u get with this

does it happen to anyone else that changing the number of levels/steps for custom auto brightness from the stock 20 to anything less causes the screen go go MAX (255) brightness?

Not to bring back this thread, but this is the exact issue that has shown up in CM10 ROMs and reported by quite a few users. If you use any number of levels other than 20, brightness is locked to 255 no matter what your thresholds or sensor is registering. Have you found any workaround or fix for this?

I really thought I was the only one. I have NOT found a work around unfortunately. Rather, I've just stayed with the stock steps/levels all the while. the behaviour is still present, and I've not found any other resource or posts on the issue.

I have brought this up in another thread over at rootzwiki and others have chimed in. Perhaps I'll create a brand new thread to acknowledge it (as opposed to responding to relevant threads already created) since it doesn't appear to be getting traction in finding a solution.

Light Sensor / Auto Brightness - Too few steps at brighter levels

Something that's been bugging me with the HOX is the light sensor and auto brightness. I've been trying apps to customise the levels but outdoors has been causing me issues.
On a bright day, when I'm in the shade, a level of 50% brightness is about right for me and in direct sunlight I need it at 100%. However, both of these conditions have the same light sensor value of 10240 lux (ie maximum) from the light sensor, despite being a big change in ambient light.
Below are the available steps with the stock sensor and as you can see there's a massive gap between the last 2. I appreciate the levels are logarithmic but there's a very perceivable difference between those values and I would estimate that over half my use falls between them.
Is there anyway devs could unlock extra values or are we stuck with these? I'm sure my previous phones had more than these.
10
40
90
160
225
320
640
1280
2600
10240

I believe these are the available steps with a desire hd. There's more throughout but in particular an additional 5 in the upper level

You can add extra steps within this app but they won't get utilised because the light sensor doesn't report any intermediate values between 2600 & 10240

Probably going to have to be a kernel source code deal.

I hope you're right and it can be done.
The sensor is a CM3602, the same as many devices including the Desire HD so it doesn't appear to be a hardware limitation as that has much better resolution.

may be it's on rom side too and not only on kernel side. libs for sensors are compiled into roms, too. and as of my knowledge these values are given in rom libs. but i may be wrong

going to have a closer look into this... it's enerving, you're right. starting this earliest coming monday -> [email protected]

it's onkernel side; messed around a bit with it but wasn't succesful so far will search a little bit more, found this http://forum.xda-developers.com/showthread.php?t=1277700 so far, first point to start with but tegra has completely different code...

[Q] Xperia S - Heats and lags, sometimes pauses games

Hi guys!
I got my SXS on 24 December and i try to play games (etc. Dead Space NFS Most Wanted) but my phone gets a bit hot (not very, but its a bit uncomfortable for my hands) but the bigger problem is: it drops the CPU clocks to 805 (?) MHz and its make games unplayable. All stock on my phone and I try to play nonpirate games. The worst is, sometimes the games pause automatically.
The phone do that too when I start playing. (So thats isn't hot and still lags, and pauses...)
Any suggestions?

only pauses, lags, and heats? man you are lucky..
my xperia ion is nowhere better. after 1st time playing dead space, it doesn't get hot or get lags. it simply rage quit and not letting me play every time i start the game.. all stock no pirate as well.
btw, xperia ion will be my last android phone, yes, no more android, but still other sony devices. i so hate the way android works, even though you can really enjoy the customization and apps integration, but seriously nothing else. i have lost all the faith on android and sony mobile. i don't wanna struggle just to get something i want to work. i want something reliable, and that's definitely not android.

Reboot your phone will no longer lag during heavy game! Before if u reach 53 degree u'll lose performance. Now It will not clocked down until 63 Degree.
Thank me, if I deserved it.
