Hey ALL ;),
According to my research If a video has a height of:
> 576 then its DVD Quality (for PAL)
> 720 then its 720p / 720i
> 1080 then its 1080p / 1080i
Although I believe it would depend on the source and the codec used as to whether a video file can be truly described as being HD.
But what happens if the video file does not conform to any of the video heights? For instance if the video has a height of 588 or 905 - does it make them 588p (/ 588i) and 905p (/ 905i)
Also I would to point out that some video files claim to be 1080p when there dimensions are 1900 x 800 so what does that make this?
Is there an easy way of checking if a video file is HD?
