FCP - Motion Question	Can't Post

I shot a football game for a city league the other night. Turn out pretty good. I used motion to do a scoreboard ticker and I have it popping up everytime the score changes in the game. It looks pretty cool. But the only thing I noticed is that anytime I have the scoreboard from motion display, the video becomes a bit choppy or almost a slight strobe effect. Does anyone know anyway I can eliminate the problem with the video, or am I missing something.

Thanks
Tim

You don't have much here about the specific environment (RT timeline, rendered timeline, whatever) so I'll guess you're in an RT timeline. I can tell you that unless you have a very hefty Mac, it's likely that the problem is that the Motion sequence us using a lot of bandwidth, forcing the DV into a low quality proxy.

Completely render the timeline (including audio mixdown) and see if that helps. If you've done that already, you have the option of rendering the Motion sequence separately and creating a QT movie, then importing that clip into FCP. This will dramatically decrease the overhead and should make everything play nicely after rendering the timeline.

Motion is a wonderful application, but it really uses up your system. It likes lots of processor power, lots of RAM, lots of fast disk, and all the video board you can afford to throw at it. It's not amazing that there's no direct equivalent for a PC. Running a "live" Motion sequence in the FCP timeline is asking a lot unless your system is way fast.

I'm considering going to an X800 board to increase my Motion performance...

BTW, all these problems should vanish when the footage is exported for transcoding. The .mov you export should play nicely in QT Viewer.

I am running a Mac G5 2.0 with 2.5GB of Ram. It looks great in the QT, but after I compile and burn the disk, the sections of the disk where the motion graphics come up look "choppy" or even a strobe like effect. I am going to try to export it as a quick time movie and see if that makes a difference.

For the record, I am not very well versed in motion, this is the first time I am trying to use and incorporate it into FCP.

Thanks for the system info & detail. I was fearful you were on a single or something.

The two things I can think of that could account for this would be the encoder not handling the high bandwidth requirements well, or a resolution issue between FCP and Motion (both have multiple resolution capabilities. Most likely encoding...

If the QT movie looks good, then it will probably help to set additional compression markers in the timeline to help out the encode. Read the manual on this subject to make sure you geet the appropriate Export with Markers, then re-encode the footage. I assume you're also encoding the audio as AC-3 to get a little more bandwidth for the video.

Motion is another journey to knowledge (just like FCP) and is worth it... it rocks! I've never seen anything like you're reporting in my work, which is part of why I suspect the encoding.
