Many people have problems when they want to upload, share or send videos because of the large video file size. True, nowadays the video quality gets increasingly better.

What You’d Better Not Do While Resizing Video

Video file size can be affected by these factors: bit rate, video codec, resolution, frame rate and video duration. Some users think that the bit rate means the amount of data transferred per seconds, so why not directly change the bit rate to reduce video size? Sure, you can do this, but only if it’s lowered with reasonable scale. Too much reduction of the bit rate may leave the video unwatchable.

The other common mistake is to change the video format for a smaller size of video.
