Really Bizzare Interlacing Issues FCP 6 (with pics)

[Chris Poisson]

Joe,

This is probably one of the top three issue here, it has been discussed to death. It’s all in the archives, but 99% of the time this problem (which can happen in different degrees no matter what) is traced to overly high resolution images. Make your images no more than twice your frame size at 72 dpi and most if not all of this will go away. Add a bit of vertical blur or gaussian blur and/or the flicker filter if it persists.

Do a search on “flickering” and you will see a bunch.

Have a wonderful day.

Chris,
Thank you for taking the time to respond to my post. The situation you described sounds eerily similar to ours – full rez images.

Will test and confirm. Thanks again for the response.

Regards,
Joe

I think what you are seeing is completely normal. It is because you have the canvas set to 100% and are therefore seeing both fields and hence the movement.

Looks like normal interlacing to me. You should see this go away if you change the Item Properties of your sequence to Field Dominance – None. My guess as to why your video clips do not show this is that they were shot as 30P. When you pause, the video clips will not show interlace.

Peter and Tom,
Thank you for the reply. I agree that it does look like normal interlacing, however… it isn’t. The issue is apparent regardless of zoom level, and continues through to the export. Regardless of field dominance settings.

I’ve taken the earlier advice of Chris, and resized the images. Currently the issue appears to be gone. Hoping he was right, and that this issue will not return.

The scary part is that the video playback looked fine when I originally put it together, then suddenly, like a switch, the images began to degrade. Hopefully the new, smaller, 72 dpi images (no video footage being used) will remain crisp.

Regards,
Joe

Two of my major gripes with FCP. How it handles speed changes in the TL and how it handles Stills. One thing you also have to be aware of, if you zoom in on the image or do any movement on it, you have to make sure that your x and y coordinates are on whole numbers (make sure there are no decimals in your x/y settings). I had to conform one project of almost all stills to whole numbers due to this PITA FCP anomaly.

I’ve had a lot of luck in changing the Motion FIltering Quality settings from Normal or Best to Faster (Linear) to take care of problems I get with fine lines or HD to SD resizing issues. This can be changes in “Sequence Settings” under the video processing tab.

Has anyone seen any improvement with the image issue when moving stills around. I have the same problem and spent two days with it. I got lines in the image and sometimes it go darker during the move. I did find that if I put none in the field dominance setting that it took a lot of the problems away. Does that affect the video? I worked with Velocity for years and images were easy to move around. This is kind of crazy. It almost seems like a bug.I do programs that I have to move images around quite a bit so moving to FCP is a bit scary.

Thanks.

This question is for Joe Kinney – or anyone who can answer for him.

Did you resolve the problem you described in the 2008 post, “Really bizarre interlacing issues in FCP6?” I’m experiencing the same problem and am not sure how to resolve it – the interlacing shows up with footage or even if a still is moving, but goes away when there is no movement.

I hope this is a simple fix as I’ve spent thousands to edit a documentary and the problems is fairly consistent throughout.

Thanks,
Amy Povah

Amy,

Tell us more…

How are you monitoring? What codec are you editing? Is your canvas size set exactly to 100?
