How to clean android mobile storeage

The mobile phone this days have gone smart but more and more features has made the mobile devices slow and it freezes time to time. 

It happens because your mobile phone space is limited and updating your phone OS software and firmware adds up more space in the limited storage space available in your phone memory.

Most of the softwares only work from the phone internal memory and not from the external micro SD cards so its better not to use games or applications which display ads as it hogs space.



The other thing to remember to have longer life for your mobile phone is to use maximum ram available and phone memory so that your phones allows the maximum apps to be installed in the phone internal storage.

It is advisable to clean cookies from the browser and app data from settings to make more space.

It can be achieved by cleaning phone cache memory, uninstalling and disabling unwanted phone apps.

There are anti virus software for mobile phones but buy a mobile package which runs smoother. Some power saving apps does not save power.

Frame rate Vs Ntsc and Pal

FRAME RATE: 
The number of images showed in a sequence in a second to give the pictures the illusion of movement. The measurement of frames in a second is called frames per second (FPS).

FILM:
It runs on 24 FPS (Traditional standard frame rate)

But now days you may shoot on 23.98, 24, 25, 29.98, 30 or 48 fps and have the same playback on digital projector or device.

DVD requires conversion from 25 fps pal to 30 fps ntsc for different regions in the world to play back on television or the reverse due to different systems.

(Update - Streaming Platform may have 23.976 or 24 fps requirement. Mostly are okay with any fps.)

OR

Shoot as 50, 60, 48, 72, 120, 1000 fps and slow down to get slow mo effect played back as 24 fps in movie theatre or 25 fps on television.

TELEVISION:
WIKIPEDIA

NTSC: National Television System Committee

30 FPS

Lines/Field: 525/60 (SD)


PAL: Phase Alternation Line

25 I FPS or 50 I

Lines/Field: 625/50 (SD)

IMAGE SOURCE


HD Lines: 1920 * 1080 I broadcasted as interlaced.

The videos when broadcasted its broken into odd and even lines for the older television which represents videos in lines.

I - Interlaced which means two fields. (Odd and even lines)

Example:

50fps (25+25=50) has two horizontal lines in single frame.

60fps (30+30=60) has two horizontal lines in single frame.

P - Progressive single filed.

Broadcasted as 1080I High Definition or 720 Standard Definition
(NTSC - 720 * 480/ PAL - 720 * 576 ).

How to stop unwanted facebook invites

We all have been frustrated with unwanted 'Candy Crush Saga' or 'Mafia' game invites from your Facebook friends multiple times a day.

People have even put up status update warning friends taking exterme measures to ban people sending such unwanted invites.

So here is a way to still be friends and not get annoyed by such invites on Facebook.

You can actually block such apps by going to Facebook settings by clicking on top right little triangle and then going to 'Blocking' tab on left pane and type the name and select the app that you want to block.


You can also 'Turn Off' notifications by hovering your mouse on the app or group notification and clicking on the 'X" you will get a option to 'Turn Off.


You can also change the email notification settings on the 'notification' Facebook page to free your cluttered email account.


This has worked for me for past few years. Settings - Blocking - Block apps.

Apple ProRes 444 codec with Gamma issues

Screen Grab
This is my 2012 diploma film G A P exported from Final Cut Pro 7. As you can see the difference shown on the above image master QuickTime MOV generated from .dpx frames in DaVinci and the Apple QuickTime ProRes 444 exported from Final Cut Pro with sound and subtitles slapped looks darker. Eventhough the H.264 are more compressed but the codec retains the Mov gamma (brightness).

Buggy DaVinci Resolve and Mavericks osx transcoding

I work as a freelance Digital Image technician. I rely on Apple ecosystem on films shot digitally or even on film format to color correct, transcode or check raw footage for feature films, ads, short films and various fashion films projects but the wired thing that I noticed is that when trancoding rushes for the edits in low res formats. The trancoding suddenly slows down from real time on a 16 GB ram on the latest Mac book Pro 15 inch retina display or over heats and makes the system crash a lot in the log in screen.

For example a trancoding is happening at 24fps (Frames per second) it slows down to 2 to 4 fps per second after sometime.

Only way to make it work is by pressing the power button risking a clone copy of the hard drive reopening the project and giving in and out points and continuing from the point the DaVainci slowed down and completed transcoding.

I am hoping for an update for Black magic product soon for this bug.

Some suggestions:
Disable the screen saver and switch of graphic switching
Revert back to old OSX
Wait for updates

UPDATES:  Install Mavericks OSX and Install the latest version of DaVinci Resolve
