HD Slow Motion - Experimenting

I took a stab recently at modifying the build.prop in order to capture slow motion video in 1280x720 (and also in 720x480).
The slow video mode by default caputres in QVGA (320x240). I started by changing every instance of 320x240 to 1280x720. No avail. I tried it again at 720x480 - also with no result.
I also tried changing the instances of 30 fps to 60 fps. Nothing worked. I gave up with the plan to approach it again later. Now it is later.
My head must be more clear now because I see that most of the changes I was making were in lines that describe encoding, not capturing. I see now that there is no mention of 24fps in the build.prop, so the regular HD recording must be getting its capture instructions from elsewhere.
The only mention of capture fps is fast mode and slow mode which are 4 fps, and 60 fps, respectively.
As a side note, I also changed the HD video encoding bitrate from bps=8000000 to bps=12000000, and even greater, but I saw no noticeable difference in quality.
I know that capturing slow motion at 60 fps in 1280x720 is likely more than the phone can handle. So - I'm not looking for that response. I am just curious to see what limit I can push it to. Maybe it can handle 60 fps at 720x480. I won't know until I can figure out how to try it.
If it isn't evident by the direction I already tried, I am no expert here. I think I know enough to prevent any serious screw ups of my phone. I am looking for a little guidance here on where to look next for changing the capture settings. Any thoughts?

I would love to be able to capture video at higher frame rates! Slow motion is awesome.
Sent from my DROIDX using XDA App

any more luck with this. I was thinking and im no dev so tell me if im retarded, but have you changed the capture fps to 60 as well as the encode to 60 and what would happen if you changed not only the instances of 30 to 60 but the instances of 1 to 30 also. just throwing some ideas off the wall because this sound like a cool idea

I thought about that, but I am holding off until I find out where the the instruction to capture 24fps for the HD video is located. I think if I find that, I will also find the settings for the slow motion.

Just because you didn't initially see a difference in quality when you bumped up the bit rate doesn't mean its not there. I've been doing green screen tests and have yeilded impressive results so far. Solid colors are still pretty blocky and a higher would definately help. I've been doing side by side tests with an iphone4 as well. So far the dx's higher bitrate yields a cleaner key. Im using a professional cyc and lights of course and primate to key it out.

At what bitrate do your tools tell you the video quality is better?

The data rate on the X is almost twice that of the iphone4. In real life the effect may give iphone more aparent contrast but in reality there is less information in the video. This is quite obvious when chroma keying.
When I have more down time i'll post some studio examples

[TWEAKS] List of build.prop tweaks (can be applied to stock ROM)

I'll share with you the /system/build.prop tweaks I have in the upcoming Nova.
You can do this on any ROM, even on stock, you just need a file manager with root access and built-in editor. Edit this file and add/change/remove values as follows.

user.feature.ls_normal=false
user.feature.sui=false
If anyone has some other tweaks or better values (tested of course) please do share.

Thanks! I go to try with the Orange stock rom v10b.

Nice Noejn.
# Helps scrolling responsiveness
windowsmgr.max_events_per_sec=150
Here I use 260 and it is very smooth and responsive. The maximum value for this tweak is 300.
# Save battery
wifi.supplicant_scan_interval=180
180 is the scan interval in seconds so you can use a lower or higher value.
Good topic

Code:
# Raise JPG quality to 100%
ro.media.enc.jpeg.quality=100
This will make for very large files. I would suggest using a value of 90-95, this will be indistinguishable from quality 100 while leaving smaller files. You can test this yourself by encoding any high quality image using various JPEG quality settings with the image tool of your choice.
Code:
# Net tweaks
net.tcp.buffersize.default=4096,87380,256960,4096,16384,256960
net.tcp.buffersize.wifi=4096,87380,256960,4096,16384,256960
net.tcp.buffersize.umts=4096,87380,256960,4096,16384,256960
net.tcp.buffersize.gprs=4096,87380,256960,4096,16384,256960
net.tcp.buffersize.edge=4096,87380,256960,4096,16384,256960
I don't know what those values used to be in their default state, but I am sure that it isn't sensible to use the same values for all networks. TCP buffer sizes should consider bandwidth and delay of the connection, which are both vastly different between edge and wifi for example.
Other values which seem interesting are:
Code:
user.feature.lgdrm=false # disable lg drm service
I can confirm this will disable the lg drm service - I have no idea what it does, but apparently I don't need it.
Code:
user.feature.flex # don't disable this
flex must be enabled, else com.android.phone and com.android.mms will crash constantly.
These can be disabled without visibly breaking something:
Code:
user.feature.lgresource
user.feature.lgpoweroff
user.feature.ls_event
user.feature.ls_normal
user.feature.sui
Anyone know what they do?

Of course =) It will do the same for every launcher. It isn't specific for LG.

I really don't get it... If this value actually given a better performance, why didn't those LG's engineer use this value for stock ROM?
They do know aren't they?

Ask them, they come to this forum.

don't tell me they come here to learn how to make a better ROM...

Maybe the factory setting is for failsafe defaults. Like ones on computer BIOS, only advanced user dare to change to their own setting.

Noejn, but...his change are already in your NOVA rom?
Becouse when i open the build.prop i found all this tweaks. (i have your rom)

of course, it is already included in teh Nova ROM....

I would also prefer a quality factor of 90-95% in Nova as 100% results in much larger files and only slightly better quality.

My guess is they can't lose time on experimental values.
They will go for stable and heavily tested ones already.

Irrelevant. You have plenty of space in /system partition and having this really won't affect your internal memory because:
a) you already have reserved space for system partition
b) we're talking about 3 MB, tops. considering I removed 80% of LG applications which account for like 150 MB do you think that system partition is that small?
So it's a luxury we can perfectly have. Besides, I do notice 10% of quality difference.

I can confirm this will disable the lg drm service - I have no idea what it does, but apparently I don't need it.

Nice tip.
But they have a whole partition for that service, it's strange you don't notice a difference.

In the new version yes. In the old one I guess a missed a few.

build.prop tweak. it can use in stock firmware v10e?

My guess is they can't lose time on experimental values.
They will go for stable and heavily tested ones already.

Yes it could be, too, LG r&d guys surely knew about this and decided to setup this defaults. That's why smart devs like you and other nova contributors should maximize this phone potential, what next?

Yeah, I didn't found any changeable because they are already tweaked haha.

Is it right that i must add the most of your tweaks in stock rom?
Because i can't find these lines in stock rom build.prop!
There is only "dalvik.vm.heapsize=32m" to find!
And if i add these tweaks, i can simply write them on the end of the page?
With or without the "#" line?
Thank you

# Disable blackscreen issue after a call

this option didn't work for me... I even tried to change do 10, 3, even 1, I didn't see any difference...

Applied only few tweaks to stock 10e:

debug.performance.tuning=1
video.accelerate.hw=1
And now UI seems a bit too responsive and fast in some cases, heheheh

build.prop tweaks (LTE)

Has anyone modified their build.prop file for further enhancements? I did some research online and found the following, which might work. If anyone has more to add or if they can confirm that something works or not, then that would be helpful.

I did a lot of these tweaks last night and it seems to be running fine. I want to test a lot of them and determine which ones actually make the device run smoother/faster.
is it possible to make a flashable zip that pushes a new build.prop to another users device, or does that file have unique info that is specific to an individuals tab?

This is great find one thing or another that works well?

Pretty sure all our 8.9 LTE build.props will be the same.

So because I am terrible at making CWM flashable zips, this is what I did.
I used a ton of different threads for this research, so I cant really link back to a specific one...
I tested by adding the line to remove boot animation and it worked, so the rest should as well. Also, make a backup, just in case something goes terribly, terribly wrong...
--------------------
1. [Using ADB] adb pull /system/build.prop
(this will pull the file to whatever folder you have the adb files in)
2. edit build.prop with wordpad (not notepad)
I added these to the end of the build.prop file:
Code:
#extras
debug.performance.tuning=1
video.accelerate.hw=1
windowsmgr.max_events_per_sec=150
persist.sys.use_dithering=0

net.tcp.buffersize.edge=4096,87380,256960,4096,16384,256960
3. Save file
4. [Using ADB] adb remount
5. [Using ADB] adb push build.prop /system/
6. [Using ADB] adb reboot
--------------------
So yea, these seem to be working fine for me. I tried the 3g/4g booster stuff but i saw no noticeable speed differences, so I didn't keep it.

I will keep messing with stuff to see if any more functionality can be added.
Will also look into some init.d scripts as well as zipalign at boot, but thats later.

very interested to hear any details on detectable changes based on these tweaks, particularly battery life changes

[Q] Any Droid 3 build.prop tweaks?

Been experiencing terrible battery life for my XT860 after CM9.
Just looking for you direction in terms of increasing battery life through build.prop tweaks. Or maybe even some performance tweaks...
Thanks!

I'm not sure of any build.prop tweaks, but check your battery stats (system settings > battery) to see what's eating it. 'Media server' and facebook (I just switched to friendcaster for a variety of reasons and am quite pleased) were my biggest culprits, followed by news/weather feeds refreshing every 30 min by default. Setting screen brightness down (turn off auto, which will mess with hard/soft key backlights), turning off wifi/bt/gps all help too. There are possibly some tweaks that might help, but these all helped significantly and hopefully they do the same for you

Over time, I've collected most of my info from Google. Build.prop Tweaks

Wow, the suggestion about disabling News and Weather is COMPLETELY AWESOME! By this time in the day I'd usually be around 60-70% on battery life, but now I'm all the way up at 83%!
No other tweaks were used, I'm running on AOKP 05-17-2012 with my XT860 patch.

I know this was a while ago and hopefully you found your solution, but if not..
Most of those programs have a refresh interval setting (ie anytime a widget updates its displyed information). These can be found under the parent apps settings via the app drawer. You might be out of luck on some programs, but I know the stock weather/news widget and most weather do as well. Hope it helps =]

There is also tons of apps in the play store that do this for you with out even having to go into system and manually changing build.prop

True, about the legacy devices.
The question is: which ones of those can we ACTUALLY use to gain some benefit?

I personally just make the WiFi interval to 500
(Which is also misleading on the op)
And disable all kernel and system logs
Anything else is useless with kit kat and anything higher than gingerbread.
Op is just cross posting on every forum possible even though not every device has a DPI like the one stated above and heap size is also misleading.
