2. Video compression picture types - Wikipedia

   en.wikipedia.org/wiki/Video_compression_picture...

   Three types of pictures (or frames) are used in video compression: I, P, and B frames. An I‑frame ( intra-coded picture ) is a complete image, like a JPG or BMP image file. A P‑frame (Predicted picture) holds only the changes in the image from a previous frame.

3. Comparison of video codecs - Wikipedia

   en.wikipedia.org/wiki/Comparison_of_video_codecs

   The quality the codec can achieve is heavily based on the compression format the codec uses. A codec is not a format, and there may be multiple codecs that implement the same compression specification – for example, MPEG-1 codecs typically do not achieve quality/size ratio comparable to codecs that implement the more modern H.264 specification.

   One of the simpler ways of increasing the size, replacing every pixel with a number of pixels of the same color. The resulting image is larger than the original, and preserves all the original detail, but has (possibly undesirable) jaggedness. The diagonal lines of the "W", for example, now show the "stairway" shape characteristic of nearest ...

5. Video codec - Wikipedia

   en.wikipedia.org/wiki/Video_codec

   A short video explaining the concept of video codecs. A video codec is software or hardware that compresses and decompresses digital video.In the context of video compression, codec is a portmanteau of encoder and decoder, while a device that only compresses is typically called an encoder, and one that only decompresses is a decoder.

   The bit rate (speed) of the video clip; The faster the bit rate of video clips, the better the quality of the video; however, the speed of your internet connection may limit the bit rate of the video clip. For example, if you have a 56kbs dial-up connection to the internet, you will be able to watch videos with a bit rate of 56kbs or less.

7. Image scaling - Wikipedia

   en.wikipedia.org/wiki/Image_scaling

   In video technology, the magnification of digital material is known as upscaling or resolution enhancement. When scaling a vector graphic image, the graphic primitives that make up the image can be scaled using geometric transformations with no loss of image quality .
