Built-In Screen Recording 

We've been hard at work trying to find all the new and cool things that came with the update.  So we'll start off these series of videos with what we think is the coolest feature on Android 4.4 which is screen recording.

Screen recording was a feature that we first heard about during the announcement of the Galaxy Note 2, however, about a day into the launch of the device in the initial countries, the feature was removed virtually out of existence.  Eventually, 3rd party apps with the screen recording feature became available for rooted and unrooted devices.  But the quality was ok at best.  Definitely not up to HD standards.  Well, that has changed for the Galaxy Note 3.  With the Android 4.4 update, the screen recording feature is built into the OS.

Prerequsistes

To get screen recording working, you need 3 things.  One, you need to have updated to Android 4.4.  Second, you need to have the official USB drivers for your Android device.  It's true that you can connect your galaxy note 3 to your computer with generic drivers that came with your computer, but for something like this, you need the official usb drivers.  You can get them at samsung's support site by providing your model number.  And last, you need a command line tool called adb.  You can officially get them by installing the free android software developer kit from Google.  But it is a gigantic package for the little file that you need, so it may be worthwhile google searching for just the adb.exe file and download it from unofficial sources.

How to Screen Record on the Note 3

Two things you need to enable on your Android is Developer options and usb debugging.  If you haven't enabled it already, you can enable developer options by going to settings -> general -> about device and tap on the build number 7 times.  Then go into developer options and enable usb debugging.
If want to record and show where you are touching, you can enable this in the settings.
After that, connect your device to your computer and open up command prompt.  Find adb.exe.  It will be where you installed the android sdk and in the subfolder here.

Then type this command you see on the screen:
adb shell screenrecord --bit-rate 8000000 --time-limit 30 /sdcard/kitkat.mp4

As soon as you hit enter it silently starts recording.  Perform the actions you want to record.

Screen Recording Options

So there are 3 things you can change in the command line.  The bitrate, time limit, and filename.  The bitrate, I'm not sure what the limit is, but higher the better.  The downside obviously is that the higher the bitrate, the bigger the filesize.  I've tried 24 megabits or 24000000 and it looked beautiful.  You can probably even go higher if necessary.  But keep in mind, this slows down the bitrate as well as you go up in bitrate.  The time limit, you can specify up to 3 minutes or 180 seconds.  For longer recordings, at the moment, you can only do it with paid apps that require your phone to be rooted.  But we wouldn't be surprised to see unrooted apps doing this in the future as long as you are tethered to your computer.

Last, the filename.  From my tests, whenever you do a recording, always make sure you change the filename.  If you start a recording and the filename exists, it seems to erase the file that you had before and the new recorded file never appears.  So if you did video1.mp4, just change it to video2 and so on.  Also, if you try to copy the file to your computer too quickly after it appears, especially if you're doing a high bitrate capture, the file seems to get corrupt.  So after a screen recording, make sure you wait a few seconds before trying to copy the file over.

No Sound During Screen Recording?

This feature does not record the audio.  To record the audio, you can get one of these 4-pole 3.5mm minjacks and route the audio channels to the appropriate channels.  Samsung likes to switch these audio channels from the standard configuration, so you will need to try a combination of these to find which channel is for the right and left speakers.  Then simply feed it into mic jack into your computer.
So for some of you looking to do the highest quality screen recordings which is 1080p at near 60frames per second, this is the only way to do it, and it's free.
