And I’ll assume SD PAL.
So hit control-q and choose the AJA Kona PAL uncompressed 10 bit easy setup.
Make a new sequence (very important).
Drag the footage to that timeline, and when FCP asks if you want to confrom the sequence to the clip, say NO!
Render, and playback.

Thank you for your reply,
i figured the problem..
that i work HD and the aja kona sequence presets to play on broadcast monitor hasn’t all codecs of the QT again i mean HD..animation,H264 is not of them!
so i should from begin work with the codecs found in the presets or render any other codec for one of this presets..
thank you ,

November 2, 2009 at 8:38 pm[Jeremy Garchow] “FCP does not support rt playback of codecs that aren’t supported by the suite, such as h264. h264 is a web delivery codec, not an editing codec. “
And this is getting less clear all the time. Right now, the h264 clips from a 5D or 7D Canon can be thrown onto the FCP timeline, and if you say yes when asked if you want the sequence to be changed to match the clips, they play on the FCP timeline in realtime without rendering. So, somewhere deep inside, FCP has this ability and a codec for h264 playback.
Of course the Kona can’t play through to the monitors, so it’s a hollow victory.
I guess at the end of the day, we have to define what an editing codec is, or perhaps it’s being redefined for us?

The proper workflow for H.264 originated material is to convert it to something like ProRes or ProResHQ prior to dropping it into the timeline. You can use compressor for this.

WEll yes, that’s because the clip and timeline codec match. Now, try to do a cross dissolve, a 3 way cc, or whatever, and you will see just how non rt it is. Most likely, those clips are RGB, so when does the conversion to YUV happen?
[Mitch Ives] “I guess at the end of the day, we have to define what an editing codec is, or perhaps it’s being redefined for us?”
An editing codec in FCP terms, is a codec that has real time effects and real time playback in the FCP timeline out of a capture card. Something that could be played back and assemble edited to tape in real time without a render would be a couple of other requirements.

November 4, 2009 at 4:47 pmMy point was that they can even play at all. I wouldn’t try to edit that way, but I find it interesting that it can find something (a codec) that I cannot locate manually that will play this? One wonders if Apple could build on this, especially since it appears Avid can edit these files natively (haven’t verified it myself).

An h264 file? An iPhone can play an h264 file. That’s not the challenge.
[Mitch Ives] “One wonders if Apple could build on this, “
Yeah, it’s called iFrame and it’s coming to iMovie.
[Mitch Ives] “especially since it appears Avid can edit these files natively (haven’t verified it myself). “
Avid usually transcodes files upon import, a process very different to FCP. At that point, you aren’t playing back h264 files, but rather Avid codec files.
