Video Capture on the CLIQ/DEXT

[Kangal]

I have been thinking about this for a while now.
Can we expect WVGA (800x480) video at 30fps?

***Rambling
Well I've always been intrigued by why most cameras record at 24fps and learnt that it was because that was the speed the old movies were made in (film reel spins displaying 1440 pictures every minute).
I also learnt that is the minimum speed to observe smooth videos for humans. On average, less than 23 will be choppy, around 24 will be smooth, and ~50fps will be smooth for people with a trained eye (video gamers, jet pilots, astronauts).
Anything extra frames above 60fps, is usually not registered, so its like it wasn't there (and it doesn't matter since LCD screens have difficulty projecting images that fast).
After learning these I thought videos should be captured at 30fps, so that its half the maximum*, its a nice round figure and can be converted (delete 1 images from each 6) to 24fps standard.
And now that iPhone 4, is using this ideology and pushing forward at this standard the other vendors have decided to follow eg Galaxy S.
And recently we've seen the HTC Droid Incredible and the Nexus One been hacked and pushed to hit 30fps on 720p. That got me thinking, the CLIQ/DEXT has a decent quality 5MP (2584 x 1938) shooter but its horrible at video; HVGA (480x320 or 0.153MP) at 24fps.
So I thought may be it could be pushed to do WVGA (800x480 or 0.384MP) at 30fps, since that doesn't sound like much to ask for.
------

What I'm asking for is (11520000/3686400) 312% increase or an extra 7,833,600 pixels per second.
What the Nexus One achieved was a (27648000/9216000) 300% increase or an extra 18,432,000 pixels per second.

What are your thoughts?

[isocertified]

I think you forgot about motion blur when talking about 24 fps vs 60 But in another note, 30 fps @ wvga would be awesome!

[j_r0dd]

the n1 was able to do that because it has the same camera as the Desire which stock has 720P recording. if anybody could do it it would be charnsingh_online. if i remember correctly he has a cliq

[Kangal]

charnsingh_online , hope he sees this thread.
I mean judging by the camera's capabilities it should be possible, but the problem is basically the drivers/camera stack that's the issue.
Perhaps the camera used here is identical to the camera of another Android device that has more capability (looking at you Milestone).

But yes, someone should look into this if they can because it is a no-brainer.

In other news, the HTC Droid Incredible can now save video directly into mpeg-4 format.
It no longer does (phone video capture) mpeg-4 > phone auto-convert (lose quality) to .3gp > "user-PC" convert (lose more quality) to mpeg-4 ....for compatibility with many devices.

Sorry just noticed the Sony Ericson Xperia X10 runs on Cupcake (like the CLIQ/DEXT), has an 8MP camera and can do recording at WVGA @30fps. So this may be a good candidate to look into. Maybe its the same camera (but just amplified the 5MP to 8MP image = no real pixel gain) or it's totally different but may be useful source for the software stack.
Sorry this issue is quite dear to my heart, as is the lack of an LED-flashlight which I find handy.

The Droid2 I believe also has 30fps. I dont recall the resolution though.

The Droid2 I believe also has 30fps. I dont recall the resolution though.

Droid 2 has a 5mp camera and i read sumwhere on xda that u can edit the build.prob or the prob.build i cant remember im to lazy to look it up again lol

Ok i decided to look it up nd its the build.prop that people edited for better camera quality

[chagothegreat]

Remember to read all instruction, btw I wrote this while half asleep. Also remember to back up before trying this and that if your phone kicks the bucket it makes a nice paper weight.



Guys my modification did not work, I am working on a fix just do not have time. I have determined that the resolution is to great I am going to use a smaller resolution, that is still larger than the default.

here is a fix for you, not sure if it will work or not but use ADB and pull build.prop

adb remount
ADB pull /system/build.prop build.prop

this will put it in the directory in which abd is at, once you have it look for these lines of code in build.prop. (you can open it with a text editor )

no replace lines 81 through 126 with this code, I have it set so for high quality it does 800x480 @ 30 FPS max but can vary to 1 FPS, and for low quality it will be 352x288 @30FPS max and minimum of 1fps

change 352 to 800

and 288 to 480

Now copy your modified build.prop to your sdcard

adb shell

su
mount -o remount,rw -t yaffs2 /dev/block/mtdblock4 /system
mv /system/build.prop /system/build.prop.bak
cd sdcard
busybox cp -R build.prop /system
chmod 644 /system/build.prop
mount -o remount,ro -t yaffs2 /dev/block/mtdblock4 /system
sync
reboot

Enjoy dude, remember to make a back up of your phone just in case

also for better performance so your phone does not think so hard change the 30 to 24

I tried this and it didn't work. Does it work for you?

[alexdagreat1]

hmm i think ill try it out just to get another opinion to see if it worked...

didnt work for me i kept getting messages saying that no such directory existed

[chagothegreat]

hmm well I have not had a chance to try it out, I am going to try it out when I install JIT. I will give you guys an update tonight.


Ok I tried it out and it seems that the CPU on the Cliq is not strong enough so itreverts back to the old high resolution, so what I am going to do is lower the res to 640x380

[tonymy01]

All those directories do exist on the phone (hmm, my adlx-2 is mounted on mtdblock1,not 4) and I guess it was either a typo or you renamed the build.prop to something that is no longer build.prop when you edited it...
Anther way is to:
adb remount
adb shell
(if you get an error when adb remount here, then adb shell, rwsystem works for adlx-2 anyway, if not, mount, see the current mounts, and mount -o remount -r -w /dev/block/mtdblock1 /system . Ensure your mtdblock1 matches what you see when you type mount, if it isn't mtdblock1, put the correct on in ).
cp /system/build.prop /sdcard
ed /system/build.prop
1,$s/width=352/width=800/p
1,$s/height=288/height=480/p
1,$s/vid.fps=30/vid.fps=24/p
w
q

Then reboot to go back to read only, or type rosystem, or type the long:
mount -o remount -r /dev/block/mtdblock1 /system (or whatever mtdblock your system is mounted on that you found out earlier by typing mount).

did you try this?

[tonymy01]

Yep, just tried it now ;-) (I did all that before but didn't save the file).
It does buckleys (I did reboot the phone to check too). The end result is still a cruddy overcompressed 352x288 file, even with the video mode set to so called "high" quality (looks more like the front camera quality of my Nokia N95!). Totally garbage this phone is.

ok, I had a typo above, it should be 1,$s/height=288/height=480/p

[alexdagreat1]

didnt work for me it when i input ed /system/build.prop it says applet not found or something like that

[tonymy01]

The commands worked, just not the result. I thought all roms had ed, that is why i gave those instructions. are you sure you did this from shell, and it is best to copy paste the commmands so there won't be any typos. edit. hmm my ed is in /system/xbin.. and is a link to busybox, which I don't think *all* rooted roms have. I also missed the 'su' command you should type if doing this in the terminal emulator instead of adb (I do this naturally and so forgot to mention).
