Can anyone recommend (or create?) a video clip that tests various<br>
aspects of deinterlacing quality? I'm imagining something that includes<br>
samples of real movies, some with slow panning, others with fast action,<br>
some sports, some text scrolling with talking heads, some difficult<br>
textures, and some artificially created content (e.g. alternate<br>
scanlines, other tough cases). (Maybe even mix in different frame rates,<br>
and throw in a progressive section?) Pack it into a minute or two so one<br>
can quickly evaluate a deinterlacer.<br>
<br>
Ideally, each portion would include some text describing what artifacts<br>
to look for, maybe even with a circle around the region(s) to focus on.<br>
(Subtitles? Text encoded into the video?)<br>
<br>
And ideally it would come in 480i and 1080i versions.<br>
<br>
Has anyone seen such a thing? Any volunteers to put one together?<br>
It could become a standard, making conversations about deinterlacing<br>
quality more concrete.<br>
<br>
A related thought: wouldn't it be nice if while watching a video, one<br>
could pull up a menu and select the renderer and the deinterlacer?<br>
