Can Kona 2 display at 59.94 in 1080i?
on Jan 29, 2007 at 12:58:59 am

I'm editing/color correcting some 1920x1080i material in FCP 5.12 using the Avid DNxHD codec (Found it to be better then DVCPro, and smaller then Uncompressed). The catch is that it is a 59.94 frame rate. I've read that displaying it at 29.97 should be fine. But when I set the Kona 2 display settings in FCP to 29.97 it seems like it is skipping frames. There is a DVCPro HD resolution that is 59.94 which seems to smooth, but unfortunately the resolution is only 720.

Is their a way to get the Kona 2 to display at 1920x1080i at 59.94?


Thanks

1080i is 59.94 fields per second. My guess is the problem you are finding is that FCP does not like the Avid codecs. You should really use codecs that FCP is designed to work with and play in real time.

Yep. The Avid Quicktime Codecs are not optimized for realtime playback. They are intended for interchange between graphics programs and Avid systems, not for editing on competing systems.

Remember the Avid itself does not use Quicktime in realtime playback. Every Quicktime is converted to OMF or MXF media on import.

What would be a better codec that FCP can do then? My system can't handle uncompressed, and I don't want to use DVCPro HD as the frame size is so much smaller (at least internally).

That is why I went with the avid codec, seemed a good compromise between the two.

DO you have to lay this off yourself?

If not, you can cc in uncompressed, render out a self contained movie and get it to a transfer house for layoff.

Or do the whole thing in DVCPRO HD. Have you looked at DVCPro HD before judging it by frame size alone?

There's a codec called Sheer Video that's supposed to be uncompressed at really small file sizes, and there's also PhotoJPEG. I do not have experience with either of them.

[Isoparm] "What would be a better codec that FCP can do then? My system can't handle uncompressed, and I don't want to use DVCPro HD as the frame size is so much smaller (at least internally)."

DVCPro HD is an anamorphic format so that's why the frame size is smaller. And it's not "so much smaller." 1080i/60 is 1440x1080. 1080i/50 is 1280x1080. These are the native sizes.

If you don't want to work in uncompressed, this is your best alternative on FCP. If you want to work in the Avid codec, then work on an Avid. Not really sure why you would think to capture in an Avid proprietary codec and then bring that to another NLE and expect it to work in realtime.

Gary Adcock just emailed me and noted I got these backwards. It's 1440 for 1080i/50 and 1280 for 1080i/60. It's confusing and I jump back and forth between both formats now. Thanks for the heads-up Gary!
