Kona LHi, FCP & 720p

[Jeremy Garchow]

FWIW, this file plays just fine on a Kona3 and KonaLHi from the viewer.

It is 720p24 with 3:2 progressive pulldown so perhaps that’s what you are thinking is stuttery as technically 60% of the frames are dupes.

It looks normal and plays fine, though. There isn’t a problem with this clip.

As Bob says, it might be system related.

It’s a fairly new Mac (MacPro 4.1 Quad-Core Intel Xeon 2.66Ghz, 8gigs of ram.On the xserve (6 years old) I changed the pre read fetch to the middle option, it was on the 128 option. But the problem occurs on the internal raid as well. PCI slot assignments. Fibre card is slot 4 (dual channel) ATI Radeon is slot 1 kona is slot 4 and matrox compressHD is slot 3

I think I’ve solved the problem. I’d decided to remove my Matrox card to see if I had the playback problem without it.

In the process of tearing the computer apart, i discovered that the Kona card was loose. The aluminum bar that holds the pci cards in with the 2 knurled knobs wasn’t tight enough and both the kona and matrox card were flopping around.

After re-seating the cards, I took a pliers to the knurled knobs and made sure there was no pci wiggling going on in there. I put it all back together and everything seems to be all better.

Thanks for all the suggestions and the confirmation that it should work.
