Have you wondered thinking that how a full HD movie comes in size around 1GB but while recording using your Handycam or mobile camera in full HD resolution, 1GB size gets consumed just in 10-15 minutes of recording?
Well, the simplest answer to this question is “video compression“.
The movies which we download or watch over the internet are compressed version, hence their sizes are comparatively smaller than the video of the same length we record from our mobile device or Handycam.
Now, you may need to understand how these ‘video compression” works?
Well, there are two major methods of compression, one is called Intraframe Compression and other is Interframe Compression.
In simple words, this method of compression compresses each frame of a video individually and then merges each frame to form compressed video.
Now, suppose we have a 10 minutes video in 1080p (1920×1080) recorded at 30 FPS, which means there are 30 full HD frames in one second. So, with Intraframe Compression, the system (software) splits each frame and compresses it using any standard algorithm, such as JPEG.
Once the compression is done to each frame, the system merges them all to form the compressed video.
Sadly, this technique fails to save data (size) efficiently. And hence we go for the second option, which is Interframe Compression.
In simple words, this method of compression compresses the video by analyzing the frames and pixels.
Now suppose, we have a 10 minutes video in 1080p (1920×1080) recorded at 30 FPS, which also means there are 30 full HD frames in one second. So, with Interframe compression, the system analyses each pixel color of frames and checks which are static pixels.
Those pixels are static throughout the video, are just instructed to not to change anything, hence huge data/memory is saved.
The system also predicts next frame by comparing last few frames and hence instruct to change or not to change pixel values.
Interframe Compression is the most commonly used video compression technique.
