Video resolution Lower quality = 176 x 144 px Higher quality = 480 x 360 px

For creating HD and MD resolutions of a video, first you must know the pixel density of the target device that will play the video. If you don't know, you must create multiple HD and MD videos for each pixel density category.

Categories:

• HDPI(160 pixel per inch)
• MDPI(240 pixel per inch)
• XHDPI(320 pixel per inch)
• XXHDPI(640 pixel per inch)
• XXXHDPI(1280 pixel per inch and above)
