jerky video input frame..

hi this is monty from far east
I have catalyst pro 2008 8core machine with 2 of LFG & multibridge pro

question is that is there any issue with 29.97 fps live input?
I have jerky video input (especially with camera PGM) every 5 second.
it looks like pull down frame drop sometimes...

when I change to 25fps it looks okay...
but here is NTSC area.

please help
thank you
monty

Hi Monty

Hope you are well

Your frame rates should all be the same (or exact multiple) throughout the system...

ie - if your screen runs at 60Hz, then your content should be 30fps and your video inputs should be 30fps (NTSC)

If they are different - then you may see flicker or 'jerky' video input...
