Video resolution and memory FAQs for Android users

Overview

Once you start using Swivl for extended periods of time there are many things to consider, like the created video files can get rather large. There are many ways to deal with large video files, and we are working on adding more capabilities to make it easier to get the files off the Android device and to your final destination.

Considerations

When making long recordings (like lectures or classes) there are several things to consider:

1. Power
2. Storage
3. Setup and preperation
4. Moving files

We have some recommendations on each that will make it easier for you to use Swivl.

Power

Swivl base will last approximately 4 hours. Swivl marker will last approximately 4 hours. The amount of time an Android device last is highly variable and depends on the age of the device, video recording quality, etc. Swivl does not draw any power from the Android device when they are connected.

First, you have to understand how big the video files can get depending on what Android device you use, at what resolution, and which camera. This table is to help you understand it better (based on the Swivl app version 1.7 or later):

DEVICE	CAMERA	RESOLUTION - SIZE BUTTON	SIZE: MEGABYTES PER MINUTE OF RECORDING
LG Nexus 5 Asus Nexus 7	Rear Facing	1080P - HD	~65MB
		720P - HD	~40MB
		480P - SD	~20MB
	Front Facing	720P - HD	~40MB
		480P - SD	~20MB
Samsung Galaxy S4	Rear Facing	1080P - HD	~65MB
		720P - HD	~40MB
		480P - SD	~20MB
	Front Facing	1080P - HD	~65MB
		720P - HD	~40MB
		480P - SD	~20MB
Samsung Galaxy Tab Pro 8,4 (SM-T320)		1080P - HD	~65MB
		720P - HD	~40MB
		1080P - HD	~65MB
		720P - HD	~40MB
		480P - SD	~20MB

Storage — Good ideas for dealing with video on Android devices

• Make sure you have plenty of space on your device. See table above to give you a sense of how much space you need. Ideally make sure you have 2x the space
• To find out how much available space you have on your Android device, go to Settings->DEVICE->Storage->DEVICE MEMORY or SD CARD

Setup and Preparations

• If possible, use front facing camera — this way the video will be smaller and you will be able to see yourself and the video recording status
• Record 1-2 short videos practicing the recording. Test how well the audio works — is the microphone too far? too close? Do you see where the video files are created (hint: check Swivl video library)
• Do not record one 4 hour video. Periodically stop and restart the recording. Usually it takes 10-20 seconds if you have recorded an hour video to stop and restart it.  Doing this will create more manageable files.

Moving Video Files off Android Device (Swivl App)

DO NOT MOVE LARGE VIDEOS TO YOUR Gallery — Android does not handle moving or copying large files very well — it takes a long time and sometimes fails.

Another uncommon but unique way to transfer or share directly from the Android device (preferred method)

• Goto Settings > Apps > My Files > Device Storage or SD Card > Android > Data > com.swivl.android > files > Movies > Three dots in the top right corner, tap on Select to select the video or videos > Select Share icon

You can copy the files onto to your computer. Please note that copying can take a while for very large files.
