If you want to enable clear motion, do as follows...
1. Root your device...
2. Install root explorer...
3. Open root explorer and navigate to /system
4. Mount as R/W
5. Open build.prop in text editor..
6. Got last line and add these lines..
( and also leave extra line at end..)
Save it and reboot phone... Voilla.... Ita done....
To Test it... Record a slow motion video...
Open the dialer app and type ##3646633## to open the Engineer Mode (To help you remember, ##3646633## corresponds to ##ENGMODE## in Phone Input)
Go to "Hardware Testing" tab and scroll to "Video"
Set ClearMotion Demo to 1
Now when you open video using MX Player; you will see the screen divided into two halves as shown(HW). The left side shows ClearMotion enabled and the right side shows ClearMotion disabled. This implies that ClearMotion is working. In case ClearMotion isn't working (faulty installation etc.), the screen won't divide.
But if you don't want to root your device.... Just get the stock rom of your device and edit the build.prop by your PC and add the lines above as instructed.....
