TK: Can someone try taking 720P 23.98 DVCPRO HD and cross converting to 1080P 23.98?
I’ve tested what you ask for (and a couple of other things as well), and this is what I found out.
720@23.98 -> 1080
There is in theory two ways of upconverting this video. One would be using an 1080@23.98p output and the other 1080@59.97i video output with a 3:2 pulldown added.
I can only get the decklink card to do 1080@59.97i, and not with a 3:2 pulldown, witch makes the video looks very jerky.
I can not find any way to set the output to 1080@23.98. The uprezing looks fine.
720@59.97 and 720@29.97 (Varicam) -> 1080
Upconverts to 1080@59.97. Both the motion and uprezing looks nice.
Luke, i’ve also been trying to downconvert 720@23.98 to NTSC, but it seems also here that the correct 3:2 pulldown is not added. The result is of course a jerky video. Am I doing something wrong, or is this simply not a feature yet?
If it’s not possible with the current version of the Decklink driver (v5.1), I hope you will be able to add this in the near future. It’s would be very usefull for all the people ouut there working with the Varicam.
