Last year, I decided to put online a website able to transcode (almost) every kind of video format or codec into another (from avi to mkv, from xvid to h.264, and so on); it was called onlinevideotranscoder.com (yes, I admit that my fantasy isn’t very rich), and it had been around the web for some… Continue reading How to make an online video transcoder in few minutes

H.264 output quality and bitrate
In video coding, understanding the real bitrate requirements that correspond to the desired quality is a key feature. It’s possible to assess quality by using appropriate objective metrics such as PSNR and SSIM Index, or simply through subjective methods as the Mean Opinion Score (MOS). Objective metrics are good if the aim is evaluating video… Continue reading H.264 output quality and bitrate
