[HOW TO] Enable MediaTek's ClearMotion Technology on Redmi Note 2 and All Other MIUI 7 based ROMs

Friday, December 25, 2015

Short Intro: Hey everyone! :) Coming to Redmi Note 2 from my thl 5000 was not without sacrifices. I was used to the exceedingly long battery life of thl 5000 (5000 mAh) and the multimedia features of MT6592; especially the ClearMotion technology.
Xiaomi Redmi Note 2 powered by MediaTek's powerful Helio X10 was supposed to be a desirable update; however, I found the lack of ClearMotion very disappointing and so the developer laying dormant inside me since the CyberShot Xperience camera drivers back in 2009-2010 finally came out once more. After some research into the technology (that worked on AOSP ROMs but not on MIUI), I finally managed to get ClearMotion working on MIUI 7 based ROMs; and here it is for all of you to enjoy! :)

The hype around Redmi Note 2 being launched with MediaTek's Helio X10 Processor was phenomenal; however, Xiaomi really stripped down the power of Helio X10 by excluding a vast number of multimedia features that the Redmi Note 2 was capable of; one of them being MediaTek's ClearMotion Technology.



About MediaTek's ClearMotion Technology:

ClearMotion is one of the most unique but under-rated features in the MediaTek line of processors. I honestly feel surprised why most people don't know about it. On several online forums, I saw confusion among a number of people who never experienced this feature, so I briefly want to describe how this technology works.

ClearMotion is infact a type of Motion Interpolation technology; which as wiki says is "a form of video processing in which intermediate animation frames are generated between existing ones by means of interpolation, in an attempt to make animation more fluid and to compensate for display motion blur."
In other words: when you play a movie/season at 24fps or 30fps; the processor continuously takes two or more adjacent frames from the video and generates an "average" of those frames and places it between those frames. In this way, it plays the video as if it was recorded in 60fps. In this way, the movements of the camera, the people or the objects in the video are very fluid and smooth; giving an overall pleasing and high-end video playback experience.

This effect is most prominent on movies and certain television series recorded at as they are recorded in 24fps. (Check out Game of Thrones intro on ClearMotion and it's hard not to come away impressed).

Most high-end televisions offer built-in motion interpolation for smooth video playback under different trade names (e.g. Sony calls it Motionflow whereas Samsung calls it Clearmotion rate)

HOW TO GET CLEARMOTION IN REDMI NOTE 2 AND OTHER MIUI 7 BASED ROMS

Disclaimer:
Confirmed working on most MIUI builds for Redmi Note 2. (7.0.12, 7.0.14, 7.1.4.0 CHINA, 7.1.3.0 CHINA, 5.12.24, 5.12,23, 5.11.1 etc)
Does not work on Global stable MIUI Builds beyond 7.0.12; however, it works in equivalent China builds.


Pre-requisites:
  • Rooted Redmi Note 2 (or MediaTek based Android 5.0 device on MIUI 7 ROM)
  • TWRP or CWM recovery installed
  • Flashable zip file containing ClearMotion libraries ported to MIUI: Download HEREhttp://adf.ly/1UKo4V
(Please don't mirror the file to other file sharing services: and don't mind the adfly link. The port is being given to you free of cost; and you compensate for it simply by not mirroring it. Thank you :) ) 
Method 1:
  • Download the file "Enable_ClearMotion_v2a_for_Redmi_Note_2_by_Hasaan6545.zip" and place it in your sdcard
  • Reboot into recovery and backup your ROM (as a precaution).
  • Flash the file. Reboot
  • Play a video using MX Player (or any player that supports HW decoding) and feel the difference ;)
Method 2 (Only for those who can not flash the zip for any reason; you may attempt manual installation).
  • Download the file "Enable_ClearMotion_v2a_for_Redmi_Note_2_by_Hasaan6545.zip" and place it in your sdcard. Extract the folder.
  • Using "Root Explorer", navigate to "system/build.prop" and use its built in text editor to add the following lines at the end of the file. Don't forget to add an extra empty line at the end.
persist.sys.display.clearMotion=1
persist.clearMotion.fblevel.nrm=255
persist.clearMotion.fblevel.bdr=255
ro.mtk_clearmotion_support=1
ro.mtk_slow_motion_support=1
ro.mtk_16x_slowmotion_support=1
(Alternatively, you may add these lines to your build.prop file using any build.prop tweaker from Play Store)
  • Using Root Explorer, copy the libraries located in the zip file's system/lib folder into your phone's "root>system>lib" directory.
  • Reboot your system and play a video to see the difference (if the mod worked for you) ;)
_________________________________________________________________________________
SO YOU INSTALLED THIS MOD; NOW, HOW TO KNOW IF CLEARMOTION IS WORKING?

Once you install this mod, all videos played using hardware decoder (stock player, MX player, Facebook, YouTube etc.) will automatically be optimized by the ClearMotion technology.

Unlike AOSP, you won't have a ClearMotion option in the MIUI settings app; however, ClearMotion will be installed and it will work.

If you have doubts, you may check the working of ClearMotion and compare it with standard playback using Engineer Mode through the steps below.
  • 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". You will see the following screen.

  • Set ClearMotion Demo to 1
  • Now when you open any video using MX Player; you will see the screen divided into two halves as shown. 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.
After you enable the demo mode, if the screen divides as shown in video player, ClearMotion is working. You can compare the difference between ClearMotion on/off in this demo mode; Left side is clearmotion enabled; right side is clearmotion disabled.
  • Turn off ClearMotion demo mode (set to 0) to enable ClearMotion on fullscreen once more.

WHY NOT SIMPLY USE AOSP ROMs FOR CLEARMOTION ON REDMI NOTE 2?

AOSP ROMs for Redmi Note 2 offer ClearMotion and MiraVision by default; however, there are advantages of using ClearMotion on MIUI instead of switching to AOSP: (These advantages are subjective: no offence intended to AOSP fans - I myself am one.)
Redmi Note 2's Fast Focus is attributable to MediaTek's InstantFocus technology rather than the "PDAF sensor" it claims to have.
  • Camera with MediaTek's InstantFocus™ and TrueBright™ technology: On MIUI, we retain a good quality camera that we have to sacrifice when switching to AOSP. (Yes, the fast focus speeds and superior image quality on MIUI ROMs are not due to the "so-called" PDAF sensor; it's because of Helio X10's  InstantFocus and TrueBright technologies; both of which are operational in MIUI Camera.
  •  Most AOSP ROMs for Redmi Note 2 are (currently) plagued by an assortment of deep sleep bugs that pop up at times and drain battery during standby. This is very annoying; and is attributable to AOSP Lollipop Build 5.0.x more than the ports itself.
  • Slow Motion feature on MIUI is superior to that in AOSP's (the latter needs the stock camera app and saves videos that can be played in slow motion only through the stock video player; whereas MIUI actually exports a slow motion video in mp4 format that can be played using any player, and can also be shared)
  • I really feel suited to AOSP, but the MIUI ROM also has much eye candy to offer.
