<div dir="ltr"><br>Hi,<br><br>I just recently started looking at HTML5 and noticed the video tag. Neat addition.<br>I also noticed that it as an attribute named 'pixelratio', however, as you know this<br>is never an integer, but rather is the result of a fraction (i.e. ratio). As for proper<br>
playback of video frames, it is important to understand exact float and therefore<br>I would suggest either expressing it as a ratio of two 32-bit integers separated by a colon (or slash) or use two<br>different attributes. This avoids unintentional rounding.<br>
<br>Something roughly along the lines of:<br><br><video pixelratio="10:11"> <!-- 525 composite NTSC --><br><video pixelratio="59:54"> <!-- 625 composite PAL --><br><video pixelratio="1018:1062"> <!-- 1920x1035 HDTV SMPTE RP 187-1995 --><br>
<br><video parhSpacing="10" parvSpacing=11"><br><br>Container formats tend to store this information in a ratio like this and not in a float.</div></blockquote><div><br>Please excuse me for referencing the video tag as, after further reading, it is apparent that the pixelratio attribute is applied to the source tag. Regardless, I believe the same points apply, so therefore please mentally /video/source/ . Thank you and sorry for the confusion and stress I may caused.<br>
