2. 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.

3. Video super-resolution - Wikipedia

   en.wikipedia.org/wiki/Video_super-resolution

   Video super-resolution (VSR) is the process of generating high-resolution video frames from the given low-resolution video frames. Unlike single-image super-resolution (SISR) , the main goal is not only to restore more fine details while saving coarse ones, but also to preserve motion consistency.

4. Quarter-pixel motion - Wikipedia

   en.wikipedia.org/wiki/Quarter-pixel_motion

   Video encoding software products such as Xvid, 3ivx, and DivX Pro Codec, which are based upon the MPEG-4 specification, use motion estimation algorithms to significantly improve video compression. The default level of resolution for motion estimation for most MPEG-4 ASP implementations is half a pixel, although quarter pixel is specified under ...

   The company has released beta firmware that lets its Fusion VR camera capture 5.6K spherical video at 24 frames per second. That's not a huge bump over the original 5.2K, but it could still be ...

   x264 contains some psychovisual enhancements which aim to increase the subjective video quality of the encoded video.. Adaptive quantisation in two modes using VAQ.The second mode, a later addition, adapts the strength per frame in an attempt to improve the quality.

7. Advanced Video Coding - Wikipedia

   H.264 can often perform radically better than MPEG-2 video—typically obtaining the same quality at half of the bit rate or less, especially on high bit rate and high resolution video content. [50] Like other ISO/IEC MPEG video standards, H.264/AVC has a reference software implementation that can be freely downloaded. [51]
