Rate convert – 720p50 to 720p25
One of the drawbacks about not living in the USA is that our local peculiarities occasionally get forgotten (No!! I do NOT want to load US Letter).
So while my Hall Research scan converter gives me heaps of 30/60 fps options I only have one 720P output. So my question is “can I drop 720p50 to 720p25 with the Ki Pro?”
Sure I can work with 50 in FCP on a 25p timeline, but it is overkill and Motion seems to get upset (weird loss of audio sync).Thanks
Charles.

If your camera sends Vfr info @25p then yes. Otherwise you have to work at the baseband of 50

Cool, thanks.
I probably should have explained workflow a bit better – doesn’t change the answer though 🙂
Conference Session – PC/Laptop VGA powerpoint presentation into scan converter (with desk audio for manual rough sync with head-shot of presenter), scan converter HDMI into Ki Pro at 720p50. Combine camera and Ki Pro source onto FCP time-line with some round-tripping through Motion for effects.
Anyway, I guess since the scan converter givers me 720p50 – that’s what I will have to work with 🙂Thanks
Charles.

720p25 only exists on storage devices. As a signal, it is not sent over baseband video, only 720p50. If your scan converter was capable of sending rp188 the Ki would be able to extract the 25 frames you’d like to keep out of the 50p signal, but alas that’s a tall order.
