Playback not smooth

[Claude Lyneis]

Playback is all about the video card in your Mac. Once I got a new iMac the playback smoothed out.

Do your clips have audio? I noticed on my system that I have to have audio under the footage (whether it is from the actual clip or added music) to play smoothly. This seems to be a rare bug, independent of system configuration. We have a few Mac Pro FCP X systems with all the same configurations and this only happens on one.

What is the codec, frame rate, etc. I assume you have the latest drivers from AJA?

It looks smooth on the computer screen but the main preview goes out to AJA Kona SDI box and through another Kona mini converter from SDI to HDMI. I work on an Xserve dual 2.93 nehalem machine

All clips have audio and its playing well, Under system prefs, I selected kona as audio out. If there is a bug, are there any fix at this time? Thanks

Codec proRes, frame rate from canon dslr and latest drivers from AJA. Anything I’m missing? I tried waiting and probably theres some background rendering going on but nothing. Any advice?

Playback should be smooth with that config. One thing to check is the frame rate and size of the video out matches your timeline. On my Matrox mx02 there is a specific setting both in system prefs and prefs for FCP. I would double check that, then if you still have trouble i would give AJA a shout.

Gerry,

Is playback without the Kona working well? I’m thinking there is something up with the Kona if everything else is working fine. I would contact AJA.

BTW. With your setup everything should be running very smoothly, especially just playback without any extensive compositing. On my system I have Canon 7D h264 footage (not optimized) playing back a high quality with my mx02 on, and waveform, and I am able to stack several color corrections on that footage and still not have any dropped frames (and I have a 2006 MacPro). Of course FCP X will start dropping frames as any app would once you max it out on compositing, but it should handle all the basics without any problem.

If you really need some help I’ll be happy to screen share with you. Email me at my creative cow username without the period at me.com
