I updated the test patterns again. Pattern 1, the one icester linked to, you need to use the galsses, but pattern 2 you don't need the glasses just a dslr camera at a fast enough shutter speed you can see the pattern, you don't need glasses for pattern 2.
Pattern 2 is 30 white bars for the 30fps source, 30fps per eye.
The 30 bars light up one at a time so all 30 bars have lit up in one second, 30fps.
I also have one with 24 bars and all 24 bars light up in one second, 24fps per eye.
It is zero parallax, so only one bar should be lit up at any one time.
It's possible to measure a box and wait for the bar to lightit up and see if the white is larger than the box, but the pattern is fast and this might bother your eyes if you watch it too long.
The moving bars are the full height of both 1080 and 720.
This is the avs code I used:
loadplugin("C:\\Program Files\\AviSynth 2.5\\plugins\\DirectShowSource.dll")
left=directshowsource("C:\\Users\\GreenEyz\\Desktop\\30 seconds of 30p.avi", audio=false, 29.970).crop(0, 0, -35, 0).addborders(0, 0, 70, 0)
right=directshowsource("C:\\Users\\GreenEyz\\Desktop\\30 seconds of 30p.avi", audio=false, 29.970).crop(35, 0, 0, 0)
return stackhorizontal(left, right).converttoyv12()
The source this was used on was a 30 second 30p avi. The entire design for pattern 2 was drawn in MS paint.
